Litigating Birthright Citizenship in the Shadow of World War II: The Continuing Relevance of a Forgotten Case

With the question of birthright citizenship before the Supreme Court this term in Trump v. Barbara , this Article explores the last time that federal courts confronted an attempt to restrict birthright citizenship. It tells the story of two lawsuits, Regan v. King and Fisk v. Wade , filed in 1942 by organizations seeking to overturn United States v. Wong Kim Ark , the 1898 Supreme Court decision that affirmed the broad scope of birthright citizenship under the Fourteenth Amendment. While the cases left little mark doctrinally, their history sheds light on a dimension of birthright citizenship litigation that has received little prior attention: the degree to which restrictionist arguments, past and present, have relied on the statutory frameworks of their respective eras. The 1942 litigation, which represented the culmination of two decades of efforts by anti-Asian groups to strip Japanese Americans of citizenship, sought to tether judicial interpretation of the Fourteenth Amendment’s Citizenship Clause to the racial exclusions then embodied in the immigration and naturalization laws. While the restrictionist arguments being put forward today are quite different, they, too, are deeply dependent on a particular statutory framework – namely, the array of late-twentiethcentury legislative changes that have collectively produced the contemporary construction of immigrant illegality. This Article argues that if courts were to allow the interpretation of the Fourteenth Amendment’s Citizenship Clause be guided by the shifting configurations of exclusion embodied in U.S. immigration policy, they would be defeating one of the central aims of the Fourteenth Amendment: to place birthright citizenship beyond the reach of repeal by a subsequent Congress.

Introduction

With the Supreme Court poised to rule on the scope of birthright citizenship this term in Trump v. Barbara ,1Trump v. Barbara, No. 25-365, 2025 WL 3493157 (U.S. Dec. 5, 2025) (mem.) (granting certiorari before judgment). The litigation concerns the legality of Exec. Order No. 14160, 90 Fed. Reg. 8449 (Jan. 20, 2025). See infra notes 278-83 and accompanying text. this Article argues that we have much to learn from a close examination of the last time that a challenge to the scope of birthright citizenship wound its way through the federal courts. It tells the story of Regan v. King 249 F. Supp. 222 (N.D. Cal. 1942), aff’d 134 F.2d 413 (9th Cir. 1943). and Fisk v. Wade, 3Fisk v. Wade, No. 22177R (N. D. Cal. June 17, 1942) (on file with Nat’l Archives, Records of District Courts of the United States, Record Group 21.6.2). twin actions filed in 1942 that sought to compel two registrars of voters, in San Francisco and in Alameda County, to remove the names of Japanese Americans from the voter rolls. Although the cases were nominally about voting rights, the plaintiffs’ primary aim was to overturn United States v. Wong Kim Ark ,4169 U.S. 649 (1898); Regan , 49 F. Supp. at 223 (“Counsel for plaintiff frankly stated that he was asking this court to overrule the leading case of United States v. Wong Kim Ark . . . because he believed the decision was erroneous.”). the Supreme Court decision that has governed the scope of birthright citizenship under the Fourteenth Amendment5 U.S. Const. amend. XIV, § 1 (“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”). since 1898.

As attempts to overturn a Supreme Court precedent, the cases were abject failures. Fisk v. Wade evaporated within a matter of weeks, when the plaintiff agreed to a voluntary dismissal after an attempt to consolidate the two cases failed.6Dismissal of Action, Fisk , No. 22177R. Regan v. King progressed further through the judicial system but met with rejection at every level.7Reporter’s Transcript, Regan v. King, 49 F. Supp. 222 (N.D. Cal. 1942) (No. 22178-S) (on file with Nat’l Archives, Records of District Courts of the United States, Record Group 21, Civil Case Files (1912-2004)). In July 1942, the District Court dismissed the case under a straightforward application of Wong Kim Ark .8 Regan , 49 F. Supp. 222. The following February, the judges of the Court of Appeals for the Ninth Circuit were so certain that the case lacked merit that they announced their decision from the bench – affirming dismissal of the complaint – immediately following the following the plaintiff-appellant’s argument without even hearing an opposing argument.9Regan v. King, 134 F.2d 413 (9th Cir. 1943) (per curiam). On May 17, 1943, a little over a year after the complaint was filed, the Supreme Court denied certiorari.10Regan v. King, 319 U.S. 753 (1943).

It would be easy to write the cases off as curiosities. Fisk v. Wade has almost never been mentioned since, and although Regan v. King has been the subject of some scholarly attention,11The most detailed accounts of the litigation can be found in the scholarship of historian Greg Robinson. See Greg Robinson with Frank H. Wu, In Defense of Birthright Citizenship: The JACL, the NAACP, and Regan v. King, 3 AABANY L. Rev. 1 (2014); Greg Robinson , After Camp: Portraits in Midcentury Japanese American Life and Politics 171-82 (2012) [hereinafter Robinson , After Camp ] (profiling attorney Hugh Macbeth); Greg Robinson, When Birthright Citizenship Was Last “Reconsidered”: Regan v. King and Asian Americans Part III , The Faculty Lounge (Aug. 9, 2010) [hereinafter Robinson, Birthright Citizenship ] (on file with the Michigan Journal of Race & Law); Greg Robinson, Regan v. King , Densho Encycl. (Feb. 6, 2025, at 05:44 ET) [hereinafter Robinson, Regan ], https:// encyclopedia.densho.org/Regan_v._King/ [https://web.archive.org/web/20251027200847/ https://encyclopedia.densho.org/Regan_v._King/]; see also Rachel E. Rosenbloom, Policing the Borders of Birthright Citizenship: Some Thoughts on the New (and Old) Restrictionism , 51 Washburn L.J. 311, 319 (2012) (discussing Regan v. King in the context of the broader history of efforts to restrict birthright citizenship). it has played little role in commentary on the current assault on birthright citizenship. Despite their doctrinal insignificance, however, the cases are worth a closer look. Falling approximately at the midpoint between the Supreme Court’s 1898 decision in Wong Kim Ark and the emergence of the contemporary movement to restrict birthright citizenship, they provide a window into the evolution of debates about the Citizenship Clause over the course of the twentieth century, and an opportunity to view the current attempt to restrict birthright citizenship from a new angle.

Regan v. King and Fisk v. Wade were filed five months after the Japanese military’s attack on Pearl Harbor, at the height of wartime anti-Japanese sentiment. It would be a mistake, however, to see the cases as simply a manifestation of wartime hysteria. Anti-Asian groups in California had been trying for over two decades to deprive Japanese Americans of citizenship.12 See infra Part II.A. The groups behind the litigation thought that the wartime rise in anti-Japanese animus would provide a new opening for them. They were not wrong about the changing landscape: public opinion was more supportive of their efforts than ever before, and Earl Warren, then serving as attorney general of California, lent the effort support behind the scenes.13 See infra Part II.B. However, the attempt ultimately failed, and the litigation was one of the last acts of a movement whose influence, once significant in California politics, was waning.

If the litigation can be seen as the last gasp of a particular chapter of American racial nativism, it also tells a story about the emergence of new configurations of legal advocacy in defense of birthright citizenship. Regan v. King attracted the attention of attorneys from the American Civil Liberties Union (ACLU), the National Lawyers Guild, the Japanese American Citizens League (JACL), and the National Association for the Advancement of Colored People (NAACP).14 See infra Parts II.D, II.E . The involvement of civil rights advocates illustrates the broad changes that were occurring at mid-century, both in the alignment of social movements and in the rhetoric of debates about citizenship. Their interventions through amicus curiae briefs marked the first time since the passage of the Fourteenth Amendment that debates over the Citizenship Clause ceased to revolve solely around the contested meanings of the Civil War and Reconstruction. World War II and the fight against Nazism provided a new paradigm for discussions of citizenship, race, and democracy.

This Article tells the story of the 1942 litigation, and then considers its contemporary relevance. Part I briefly reviews the Supreme Court’s interpretation of the Citizenship Clause in the decades following the ratification of the Fourteenth Amendment. Part II examines the lead-up to the filing of the complaints in Fisk v. Wade and Regan v. King , and the path that Regan v. King took through the District Court and Court of Appeals. It focuses in particular on the plaintiffs’ attempt to tether birthright citizenship to the racial exclusions then embodied in both the naturalization statute and the statutes governing the admission of foreign nationals to the United States.15 See infra Part II.D. Part III argues that this aspect of the 1942 litigation – the extent to which restrictionists’ arguments relied on the statutory frameworks of racially restricted naturalization and Asian exclusion – can help us understand the current attack on birthright citizenship in a new way. Although the contemporary effort to restrict birthright citizenship presents entirely different legal arguments than those raised in 1942, it, too, relies heavily on statutory frameworks, seeking to tether birthright citizenship to an array of late-twentieth-century legislative changes that have collectively produced the contemporary construction of immigrant illegality.16Although the United States has a long history of immigration restriction, the contours and significance of unauthorized status have shifted over time. See infra notes 303-22 and accompanying text. The boundaries that restrictionists sought to draw around birthright citizenship in 1942 would be difficult to articulate today, in light of the changes that have occurred in statutory law, while the boundaries that restrictionists seek to draw today would have made little sense to the restrictionists of the 1940s. Part III explores this dynamic, and argues that it offers yet another reason, beyond the doctrinal arguments that have already been identified, for courts to reject the interpretation of the Fourteenth Amendment that the Trump administration has advanced. If courts were to allow statutes enacted over the past few decades to shape the contours of birthright citizenship, they would be defeating one of the central aims of the Fourteenth Amendment: to place birthright citizenship beyond the reach of repeal by a subsequent Congress.17 See United States v. Wong Kim Ark, 169 U.S. 649 (1898) (recognizing the framers’ desire to protect birthright citizenship from repeal by a future Congress); see infra notes 324-26.

Part I: The Citizenship Clause

The Fourteenth Amendment, ratified in 1868, declares that “[a]ll persons born . . . in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”18 U.S. Const. amend. XIV, § 1. These words radically reconfigured the relationship between race and citizenship in the United States. In the years leading up to the Civil War, policing the racial boundaries of citizenship formed a key component of the nation’s racial caste system. This caste system was expressed most notoriously in the Supreme Court’s 1857 decision in Dred Scott v. Sandford , in which the Court held that no American of African descent could be recognized as a citizen of the United States because the nation’s founders had intended to erect a “perpetual and impassable barrier . . . between the white race and the one which they had reduced to slavery.”1960 U.S. 393, 409 (1857). Less than a decade after Dred Scott , following the Union victory in the Civil War, Radical Republicans in Congress overturned the decision, first through the passage of the Civil Rights Act of 1866,20Civil Rights Act of 1866, ch. 31, 14 Stat. 27. which provided a statutory guarantee of birthright citizenship free from racial restrictions, and then a few months later through the inclusion of the Citizenship Clause in the proposed language of the Fourteenth Amendment.

In 1866, when Senator Jacob Howard introduced the language that would become the first sentence of the Fourteenth Amendment, he proclaimed that its purpose was to “settle[] the great question of citizenship and [to] remove[] all doubt as to what persons are or are not citizens of the United States.”21 Cong. Globe , 39th Cong., 1st Sess. 2890 (1866). Over the next few decades, however, the debates continued.22On nineteenth-century debates, see Sam Erman & Nathan Perl-Rosenthal, Jus Soli Nation to Jus Soli Evasion: International Lawyers for White Supremacy and the Road Through Wong Kim Ark, 3 J. Am. Const. Hist. 615 (2025); Bernadette Meyler, The Gestation of Birthright Citizenship, 1868-1898: States’ Rights, The Law of Nations, and Mutual Consent , 15 Geo. Immigr. L.J. 519 (2001); Jonathan C. Drimmer, The Nephews of Uncle Sam: The History, Evolution, and Application of Birthright Citizenship in the United States , 9 Geo. Immigr. L.J. 667 (1995). Courts faced two questions about the language of the Citizenship Clause: who should be deemed to be born “subject to the jurisdiction” of the United States and who should be deemed to be born “in” the United States.23 See United States v. Wong Kim Ark, 169 U.S. 649 (1898) (regarding “subject to the jurisdiction”); Elk v. Wilkins, 112 U.S. 94 (1884) (same); In re Look Tin Sing, 21 F. 905 (C.C.D. Cal. 1884) (same); Gonzales v. Williams, 192 U.S. 1 (1904) (regarding overseas U.S. territories).

Two foundational cases interpreting the Citizenship Clause were decided in quick succession in the fall of 1884.24 Elk , 112 U.S. 94; In re Look Tin Sing , 21 F. 905. Two earlier cases, Minor v. Happersett, 88 U.S. 162, 167-68 (1874) and The Slaughter-House Cases, 83 U.S. 36, 73 (1872), included dicta about the Citizenship Clause but rested on the Court’s interpretation of the Privileges and Immunities Clause in Article IV of the Constitution rather than on the scope of birthright citizenship. In September of that year, Supreme Court Justice Stephen Field, riding circuit in California, authored a decision on behalf of a unanimous panel of judges in In re Look Tin Sing .2521 F. at 905. The case concerned the citizenship of Look Tin Sing, a fourteen-year-old boy who was born in California to Chinese immigrant parents.26 Id. Look had left the United States at the age of nine to be educated in China. While he was gone, Congress enacted the Chinese Exclusion Act, barring the entry of Chinese laborers.27Chinese Exclusion Act of 1882, ch. 126, 22 Stat. 581 (repealed 1943). An amendment that made the Act even harsher went into effect just before Look’s arrival. Act of July 5, 1884, ch. 220, 23 Stat. 115. The amendment required Chinese laborers who were returning to a prior residence in the United States to obtain a return certificate prior to departing the United States – a certificate that Look, for obvious reasons, could not have procured. When Look returned to California in 1884, immigration inspectors barred him from entering, citing the Chinese Exclusion Act.28 In re Look Tin Sing , 21 F. at 910. As Justice Field points out in the decision, the Act applied only to Chinese laborers, and thus would not have applied to Look – the son of a m erchant – even if his citizenship claim had failed. Id. Writing for a unanimous panel, Justice Field parsed the meaning of the phrase “subject to the jurisdiction thereof” and found that the only recognized exceptions concerned the children of diplomats, “whose residence, by a fiction of public law, is regarded as part of their own country,” and those born on a public vessel of a foreign country within U.S. waters.29 Id. at 906. Field acknowledged that Look’s parents were racially barred from citizenship under the statute governing naturalization,30 Id. at 909. which restricted naturalization to “white person[s]” and to “aliens of African nativity and . . . persons of African descent.”31The Naturalization Act of 1790 restricted naturalization to “free white person[s].” Naturalization Act of 1790, ch. 3, 1 Stat. 103 (repealed 1795). When the 1790 Act was repealed in 1795, the act that replaced it retained the “free white person” requirement. Act of Jan. 29, 1795, ch. 20, 1 Stat. 414. Congress extended naturalization to “aliens of African nativity and . . . persons of African descent” in 1870, Act of July 14, 1870, ch. 254, § 7, 16 Stat. 254, 256, and to “descendants of races indigenous to the Western hemisphere in 1940, Nationality Act of 1940, ch. 876, § 303, 54 Stat. 1140. See generally Ian Haney López , White by Law: The Legal Construction of Race (2006) (tracing the history of racial exclusions in the naturalization statute); Gabriel J. Chin & Paul Finkelman, The “Free White Person” Clause of the Naturalization Act of 1790 as Super-Statute, 65 Wm. & Mary L. Rev. 1047 (2024) (discussing the broad impact of the racially exclusionary language of the Naturalization Act of 1790). However, Field concluded that this fact did not change the analysis. At the time of the adoption of the Fourteenth Amendment, Field pointed out, the naturalization laws excluded Black people born outside the United States from becoming citizens,32 In re Look Tin Sing , 21 F. at 909. but the framers of the Fourteenth Amendment showed no intention of excluding their children from citizenship.33 Id. By the same token, Field concluded, Look Tin Sing’s citizenship was not conditional on his parents’ eligibility for naturalization.34 Id.

The next decision came just five weeks later, in a case that must have been on Justice Field’s mind when he wrote the decision in Look Tin Sing . In April 1884, shortly before Field had departed Washington for California, the Supreme Court had heard oral arguments in Elk v. Wilkins , a case concerning the citizenship of a man named John Elk who had severed his relationship with the Ho-Chunk (Winnebago) Nation and had taken up residence in Omaha, Nebraska.35112 U.S. 94 (1884); Is a Non-Tribal Indian a Citizen? , Omaha Daily Bee , Apr. 5, 1884, at 4 (reporting on oral arguments in Elk ). The Supreme Court’s decision does not specify which nation Elk belonged to, but scholars have identified him as Ho-Chunk (Winnebago). See Gregory Ablavsky & Bethany Berger, “ Subject to the Jurisdiction Thereof”: The Indian Law Context , 100 N.Y.U. L. Rev. Online 201, 203 (2025); Bethany R. Berger, Birthright Citizenship on Trial: Elk v. Wilkins and United States v. Wong Kim Ark, 37 Cardozo L. Rev. 1185, 1215 (2016). Elk was denied the right to vote and challenged the denial, arguing that he was a citizen under the Fourteenth Amendment.36 Elk , 112 U.S. at 94-95. The case remained pending while the Court was in summer recess. When Field returned to Washington in the fall, five weeks after he authored the Look Tin Sing decision, he joined the majority in Elk v. Wilkins, holding that Elk, unlike Look, was not born a citizen of the United States. In a decision written by Justice Horace Gray, the Court held that those born into membership in Native nations were not born “subject to the jurisdiction” of the United States and were therefore not citizens under the Fourteenth Amendment.37 Id. at 109. The Court reasoned that “Indians born . . . members of, and owing immediate allegiance to, one of the Indiana tribes, (an alien though dependent power[]),” were not birthright citizens.38 Id. at 102. Although they were “in a geographical sense born in the United States,” they were

no more ‘born in the United States and subject to the jurisdiction thereof,’ within the meaning of the first section of the fourteenth amendment, than the children of subjects of any foreign government born within the domain of that government, or the children born within the United States, of ambassadors or other public ministers of foreign nations.39 Id.

Together, the two cases drew a clear line. Children born into membership in sovereign Native nations were to be treated in the same way that children of subjects of any foreign government born within the domain of that government (for example, a child born in France to French parents) would be treated; the fact that Native nations were located within the borders of the United States did not change the analysis. Courts also recognized the children of diplomats and children born on a public vessel of a foreign country while within U.S. waters as not being born fully subject to the jurisdiction of the United States despite the physical location of their birth. But children such as Look, who did not fall under these exceptions, were birthright citizens under the Fourteenth Amendment – even if their own parents were barred from citizenship.

Elk was decided at a moment when federal policy toward Indigenous people was in flux. Soon after the decision, the federal government embarked on an aggressive campaign to promote U.S. citizenship, assimilation, and private land ownership among Indigenous people in ways calculated to break up Native land and bring about the end of Native sovereignty.40A large body of scholarship has analyzed the role of citizenship in dismantling Indigenous sovereignty. See, e.g. , Stephen Kantrowitz, White Supremacy, Settler Colonialism, and the Two Citizenships of the Fourteenth Amendment , 10 J. Civ. War Era 29, 32 (2020); Robert B. Porter, The Demise of the Ongwehoweh and the Rise of the Native Americans: Redressing the Genocidal Act of Forcing American Citizenship upon Indigenous Peoples , 15 Harv. BlackLetter L.J. 107 (1999); Kevin Bruyneel, Challenging American Boundaries: Indigenous People and the “Gift” of U.S. Citizenship , 18 Stud. Am. Pol. Dev. 30 (2004). Over the decades that followed, many Indigenous people became U.S. citizens under the Dawes Act of 1888 and subsequent legislation.41The General Allotment (Dawes) Act of 1887 gave the federal government broad authority to allot land to individuals on reservations and decreed that those who received allotments were automatically made citizens of the United States, as was “every Indian born within the territorial limits of the United States who has voluntarily taken up, within said limits, his residence separate and apart from any tribe of Indians therein, and has adopted the habits of civilized life[.]” Act of Feb. 8, 1887, ch. 119, § 6, 24 Stat. 390. In 1924, Congress passed the Indian Citizenship Act, providing that “all non-citizen Indians born within the territorial limits of the United States be, and they are hereby, declared to be citizens of the United States . . . .”42Act of June 2, 1924, ch. 233, 43 Stat. 253. In light of these subsequent developments, the significance of Elk has been limited.

Look Tin Sing, on the other hand, set forth a rule that has remained in force to this day, now incorporated into Supreme Court precedent.43United States v. Wong Kim Ark, 169 U.S. 649 (1898). In the wake of the decision, federal courts began routinely granting claims where birth in the United States had been established.44This was true both in California, where the decision was binding, and in other jurisdictions, where federal courts chose to follow the decision. See, e.g. , Ex parte Chin King, 35 F. 354 (C.C.D. Or. 1888); In re Yung Sing Hee, 36 F. 437 (C.C.D. Or. 1888). In the fourteen-year period between Look Tin Sing and the Supreme Court’s adoption of the rule as Supreme Court precedent in Wong Kim Ark , no federal court reached a contrary conclusion. The only published case that has ever departed from Look Tin Sing ’s holding is a case decided by the New Jersey Supreme Court in 1895, which added a domicile requirement. See Benny v. O’Brien, 32 A. 696, 698 (N.J. 1895) (commenting that the exceptions to birthright citizenship include those “born in this country of foreign parents who are temporarily traveling here.”); see also Catherine Y. Kim, Citizenship Outside the Courts , 57 U.C. Davis L. Rev. 253, 297 (2023) (noting that “the lower federal courts during this period uniformly recognized the citizenship of ethnic Chinese persons born in the United States to noncitizen parents.”). John Wise, who oversaw the enforcement of the Chinese exclusion laws in San Francisco, reported to Attorney General Judson Harmon in 1895:

[F]or many years . . . it has been the established rule and uniform practice to permit the landing of those Chinese who have been born within the United States, and upon the sole ground that by reason of their birth they are native born citizens thereof, and as such are exempt from the provisions of the Exclusion Act . . . . [T]he cases in which such action has been taken during the past ten years are very numerous and are now of frequent occurrence.45Letter from John Wise to Judson Harmon, Att’y Gen. (Oct. 10, 1895) (on file with Nat’l Archives, General Records of the Department of Justice, Record Group 60, Letters Received, 1884-1903).

Immigration inspectors often rejected citizenship claims on factual grounds, questioning the veracity of assertions of birth within the United States.46On agency and judicial scrutiny of Chinese American citizenship claims, see Erika Lee , At America’s Gates: Chinese Immigration During the Exclusion Era , 1882-1943, at 100-09 (2003); Lucy E. Salyer , Laws Harsh as Tigers: Chinese Immigrants and the Shaping of Modern Immigration Law 150-52, 207-12 (1995). They made no headway, however, in narrowing the scope of birthright citizenship in the decade following Look Tin Sing . San Francisco attorney George Collins, who opposed recognizing the U.S.-born children of Chinese immigrants as birthright citizens, complained in 1895 that the “executive department of the general government has apparently acquiesced in Judge Field’s decision as a correct interpretation of the law.”47George D. Collins, Citizenship by Birth , 29 Am. L. Rev. 385, 385 (1895). The executive branch did not, however, entirely cease efforts to restrict the scope of birthright citizenship during this period. Professor Catherine Kim provides a detailed account of the ways in which the executive branch continued to resist a broad rule of birthright citizenship. For instance, in 1885, two Secretary of State opinions both deemed white men born in the United States to have lost their claim to birthright citizenship – in effect, to have been expatriated – on the basis of having grown up abroad and of having no intention of residing in the United States. See Kim, supra note 44, at 298-99 (citing Letter from Frederick Frelinghuysen, Sec’y of State, to John Kasson, U.S. Minister to Ger. (Jan. 15, 1885), in Papers Relating to the Foreign Relations of the United States 394-96 (1885) [hereinafter Papers Relating ]; Letter from Thomas Bayard, Sec’y of State, to Boyd Winchester, U.S. Minister to Switzer. (Nov. 28, 1885), in Papers Relating , supra , at 814-15 (1885)). In addition, in an opinion written in 1897, while Wong Kim Ark was pending at the Supreme Court, Attorney General Joseph McKenna concluded that “it [was] not yet finally decided whether or not children born in this country of subjects of the Chinese emperor are to be recognized as citizens of the United States.” See id. at 299-300 (citing Chinese – Certificates as to Citizenship, 21 Op. Att’y Gen. 581 (1897)).

It would take fourteen years before the Supreme Court ruled directly on the question raised in Look Tin Sing , but in the interim, the Court appeared to signal its approval of the holding. In 1891, in Quock Ting v. United States , the Court heard an appeal in a case involving another teenager arriving from China who claimed to have been born in the United States. In denying the appeal, the Court focused only one question: “whether the evidence[] before the court below was sufficient to show that the petitioner was a citizen of the United States.”48Quock Ting v. United States, 140 U.S. 417, 419 (1891). As Justice David Brewer noted in his dissent, that evidence revolved around a “single question”: “whether the petitioner was born in this country or not.”49 Id. at 423 (Brewer, J., dissenting). The following year, when the newly established Ninth Circuit Court of Appeals was confronted with a case involving a passenger arriving from China who claimed to have been born in the United States, the court did not even bother to cite a legal precedent when it referenced the principle that a person born in the United States to Chinese immigrant parents would be a citizen under the Fourteenth Amendment.50Gee Fook Sing v. United States, 49 F. 146 (9th Cir. 1892).

Collins’ complaint in 1895 about the executive branch’s inaction was part of an ongoing campaign to convince the Department of Justice to challenge the holding of Look Tin Sing .51On the lead-up to Wong Kim Ark , see Carol Nackenoff & Julie Novkov , American by Birth: Wong Kim Ark and the Battle for Citizenship (2021); Erman & Perl-Rosenthal, supra note 22; Amanda Frost, ” By Accident of Birth”: The Battle over Birthright Citizenship After United States v. Wong Kim Ark, 32 Yale J.L. & Human. 38 (2021); Erika Lee, Birthright Citizenship, Immigration, and the U.S. Constitution: The Story of United States v. Wong Kim Ark, in Race Law Stories 89 (Rachel F. Moran & Devon W. Carbado eds., 2008); Lucy E. Salyer, Wong Kim Ark : The Contest over Birthright Citizenship , in Immigration Stories 51 (David A. Martin & Peter H. Schuck eds., 2005). In the summer of 1895, at Collins’ instigation, President Grover Cleveland asked the Department of the Treasury (which oversaw immigration) to consider the matter.52 See Letter from George D. Collins to Grover Cleveland, President (June 6, 1895) (on file with Nat’l Archives, General Records of the Department of Justice, Record Group 60, Box 857) (requesting that Cleveland exclude U.S.-born children of Chinese immigrants from entering the United States upon arrival from abroad). Subsequent correspondence indicates that Cleveland referred the matter to the Secretary of the Treasury. See Letter from George D. Collins to John G. Carlisle, Sec’y of the Treasury (June 19, 1895) (on file with Nat’l Archives, General Records of the Department of Justice, Record Group 60, Box 857) (stating that he received a letter from the President informing him that the matter had been referred to the Secretary of the Treasury). A plan to engineer a test case was soon in place . 53Letter from Henry S. Foote, U.S. Att’y, to Judson Harmon, Att’y Gen. (Aug. 19, 1895) (on file with Nat’l Archives, General Records of the Department of Justice, Record Group 60, Box 857) (stating that he has been directed to bring a test case by the Acting Attorney General). When a U.S.-born passenger named Wong Kim Ark arrived in San Francisco on the steamship Coptic on August 31, 1895, he was refused entry, despite the fact that his U.S. citizenship had been previously recognized.54Wong had taken a previous trip to China and been admitted as a citizen upon his return. See Lee, supra note 51. In addition, prior to his second trip, he had submitted the required documentation of his citizenship to immigration officials, including signed statements from three white witnesses attesting to his birth in San Francisco. Id. at 96. Wong promptly filed a habeas corpus petition to challenge his exclusion.55 In re Wong Kim Ark, 71 F. 382, 383 (N.D. Cal. 1896), aff’d sub nom ., United States v. Wong Kim Ark, 169 U.S. 649 (1898).

The government’s gambit succeeded in propelling a test case into the courts, but it failed to overturn Look Tin Sing . In 1898, in United States v. Wong Kim Ark , the Supreme Court reached the same conclusion that Field had reached, holding that Wong was a birthright citizen.56 Wong Kim Ark , 169 U.S . 649. The court noted that, before the Civil War, it was “beyond doubt that . . . all white persons, at least, born within the sovereignty of the United States, whether children of citizens or of foreigners, excepting only children of ambassadors or public ministers of a foreign government, were native-born citizens of the United States,”57 Id. at 674-75. and held that the Fourteenth Amendment extended that principle to all, “restricted only by place and jurisdiction, and not by color or race.”58 Id. at 676. The decision recognized as exceptions only “children of foreign sovereigns or their ministers, or born on foreign public ships, or of enemies within and during a hostile occupation of part of our territory . . . .” along with “the single additional exception of children of members of the Indian tribes owing direct allegiance to their several tribes.”59 Id . at 693. The Court rejected the arguments put forth by the government (represented by Collins as well as by Solicitor-General Holmes Conrad) that sought to impose a rule of citizenship-by-descent derived from international law, rather than a rule of territorial birthright citizenship derived from the common law.60For a detailed discussion of the government’s theory, see Erman & Perl-Rosenthal, supra note 22, at 660-62.

Soon after deciding Wong Kim Ark , the Supreme Court confronted the question of the case’s applicability to the territories in America’s expanding overseas empire. In 1901, in a case concerning duties on goods arriving from Puerto Rico, the Court suggested that the Citizenship Clause did not extend to “unincorporated” territories.61Downes v. Bidwell, 182 U.S. 244, 251 (1901) (commenting that “the 14th Amendment, upon the subject of citizenship, declares only that ‘all persons born or naturalized in the United States , and subject to the jurisdiction thereof, are citizens of the United States, and of the state wherein they reside.’ Here there is a limitation to persons born or naturalized in the United States, which is not extended to persons born in any place ‘subject to their jurisdiction.’”). Three years later, in Gonzales v. Williams, the Court held that Isabel Gonzales, a woman born in Puerto Rico, was not a foreign national and therefore could not be excluded upon her arrival in New York.62192 U.S. 1, 13 (1904). The decision refers to her as “Isabella Gonzales,” but as legal historian Sam Erman has observed, she referred to herself as “Isabel.” Sam Erman, Meanings of Citizenship in the U.S. Empire: Puerto Rico, Isabel Gonzalez, and the Supreme Court, 1898 to 1905 , 27 J. Am. Ethnic Hist. 5, 27 n.1 (2008) (discussing the choice to use “Isabel” rather than “Isabella” when discussing the case). The Court stopped short, however, of declaring that Gonzales was a citizen under the Fourteenth Amendment. These cases have generally been interpreted to leave residents of unincorporated U.S. territories in an in-between status as nationals, with many, but not all, of the rights of citizens.63 See 8 U.S.C. § 1408. On the history of jurisprudence regarding citizenship in overseas U.S. territories and the history of legislation concerning the citizenship status of those born in Puerto Rico, see Sam Erman , Almost Citizens: Puerto Rico , the U.S. Constitution , and Empire (2018). Congress has since extended birthright citizenship to many U.S. territories by statute.648 U.S.C. §§ 1402-1407.

Litigation on the question of the applicability of the Citizenship Clause in U.S. territories has continued,65 See Fitisemanu v. United States, 1 F.4th 862 (10th Cir. 2021), cert. denied , 143 S. Ct. 362 (2022) (mem.) (holding that persons born in American Samoa are not citizens under the Fourteenth Amendment); Tuaua v. United States, 788 F.3d 300 (D.C. Cir. 2015), cert. denied , 579 U.S. 902 (2016) (mem.) (same). but Wong Kim Ark’ s holding with regard to those born in the continental United States has remained undisturbed. Applying Wong Kim Ark , federal courts have consistently recognized the citizenship of those born in the United States without regard to the status of their parents.66 See, e.g. , INS v. Rios-Pineda, 471 U.S. 444, 446 (1985) (referring to a child born in the United States to parents who had entered the United States without authorization as “a citizen of this country”); United States ex rel. Hintopoulos v. Shaughnessy, 353 U.S. 72, 73 (1957) (noting that a child born to two foreign nationals who had overstayed their temporary admission was “of course, an American citizen by birth.”); see also Plyler v. Doe, 457 U.S. 202, 211 n.10 (1982) (remarking that “given the historical emphasis on geographic territoriality, bounded only, if at all, by principles of sovereignty and allegiance, no plausible distinction with respect to Fourteenth Amendment ‘jurisdiction’ can be drawn between resident aliens whose entry into the United States was lawful, and resident aliens whose entry was unlawful.” (internal citation omitted)). Congress has also codified this understanding of the Citizenship Clause, first in the Nationality Act of 1940 and again, in 1952, in the Immigration and Nationality Act.67Immigration Act of 1940, Pub. L. No. 76-853, § 201(a), 54 Stat. 1137, 1138; Immigration and Nationality Act, Pub. L. No. 82-414, § 301(a)(1), 66 Stat. 163, 235 (1952) (codified at 8 U.S.C. § 1401); see also Brief of Immigration Law Scholars Kristin Collins, Gerald Neuman & Rachel Rosenbloom as Amici Curiae Supporting Appellees, CASA v.

Part II: Challenging Birthright Citizenship in the Shadow of World War II

Forty-four years after the Supreme Court decided Wong Kim Ark, two Federal District Court judges in San Francisco found themselves presiding over lawsuits arguing that the decision should be overturned. In the federal courthouse at the corner of Seventh and Mission Streets, approximately a mile and a half from the site of the former courthouse where Judge William Morrow had granted Wong Kim Ark’s habeas corpus petition,68The federal courthouse where Wong’s habeas corpus petition was heard was located on Sansome Street in San Francisco. See Northern District History , U.S. Dist. Ct.: N. Dist. Cal. , https://cand.uscourts.gov/about/northern-district-history [https://perma.cc/83WL- F7XL] (last visited Oct. 8, 2025). By 1942, the judges of the Northern District of California had moved to a courthouse located at the corner of Seventh Street and Mission Street. Id . Judge Adolphus St. Sure heard arguments in Regan v. King ,69Complaint, Regan v. King, 49 F. Supp. 222 (N.D. Cal. 1942) (No. 22178-S) [hereinafter Regan Complaint] (on file with Nat’l Archives, Records of District Courts of the United States, Record Group 21, Civil Case Files (1912-2004)). while Judge Michael Roche considered the case of Fisk v. Wade .70Complaint, Fisk v. Wade, No. 22177R (N. D. Cal. June 17, 1942) [hereinafter Fisk Complaint] (on file with Nat’l Archives, Records of District Courts of the United States, Record Group 21.6.2). Both actions were filed on the same day – May 7, 1942 – by the same attorney: Ulysses S. Webb, who had recently returned to private practice after serving as California’s attorney general for thirty-seven years.

The plaintiffs, John Regan and James Fisk, sued in their personal capacities, but both were leaders of organizations with long histories of anti- Asian advocacy. Regan was Grand Secretary of the Native Sons of the Golden West, 71 See Roger Daniels , The Politics of Prejudice: The Anti-Japanese Movement in California and the Struggle for Japanese Exclusion 85 (1977) (calling the Native Sons of the Golden West “perhaps the most influential pressure group in the state” and describing their views as “consistently reactionary and nativist”). and Fisk led the California state affiliate of the American Legion.72The American Legion, founded in 1919, was involved in anti-Japanese agitation from its founding convention. See, e.g. , Am. Legion , Committee Reports and Resolutions Adopted at the First National Convention of the American Legion 37-38 (1919) (demanding exclusion of Japanese immigrants from the United States and the exclusion from birthright citizenship of the children of immigrants ineligible to naturalize). Both Regan and Fisk, along with Webb, were core members of the California Joint Immigration Committee, a coalition that was at the center of anti-Asian organizing in California.73On the history of the CJIC, see infra note 103. Each complaint named a registrar of voters as the defendant: Regan brought suit against Cameron King, registrar for the City and County of San Francisco, while Fisk brought suit against G.E. Wade, registrar for Alameda County. 74 Fisk Complaint, supra note 70; Regan Complaint, supra note 69. Each sought a court order directing that Japanese Americans be removed from the voting rolls.75 Fisk Complaint, supra note 70, at 7-8; Regan Complaint, supra note 69, at 7-8. At the center of each complaint was the argument that the U.S.-born children of Asian immigrants were not citizens under the Fourteenth Amendment.76 Fisk Complaint, supra note 70, at 5; Regan Complaint, supra note 69, at 5. The complaints contended that “Japanese of the full blood born in the United States . . . of alien parents born in the Empire of Japan were at birth citizens . . . of the Empire of Japan, owing allegiance to that government,” were “subject to the jurisdiction of the United States of America in the same manner and to the same extent as all other aliens, but not otherwise,” and were “ineligible to citizenship in the United States of America[.]”77 Fisk Complaint, supra note 70, at 5; Regan Complaint, supra note 69, at 5.

A. The Early Roots of the Litigation

The complaints in Fisk v. Wade and Regan v. King were filed five months after the Japanese military attacked the U.S. naval base at Pearl Harbor, and the cases played out against the backdrop of the wartime incarceration of over 120,000 people of Japanese ancestry, approximately two-thirds of whom were U.S. citizens.78For a discussion of the importance of avoiding euphemisms such as “internment,” see Aiko Herzig-Yoshinaga, Words Can Lie or Clarify: Terminology of the World War II Incarceration of Japanese Americans – Part 1 , Discover Nikkei (Feb. 2, 2010), http://www.discovernikkei. org/en/journal/article/3246/ [https://perma.cc/W4EP-UVH5]; Roger Daniels, Words Do Matter: A Note on the Inappropriate Terminology and the Incarceration of the Japanese Americans – Part 1 of 5 , Discover Nikkei ( Feb. 1, 2008), http://www.discovernikkei.org/en/journal/ 2008/2/1/words-do-matter/ [https://perma.cc/8WHD-UWBK]; Terminology , Densho , https://densho.org/terminology/ [https://perma.cc/Y4UK-UTMD] (last visited Oct. 8, 2025). On the forced evacuation and incarceration of Japanese Americans, see Greg Robinson , By Order of the President: FDR and the Internment of Japanese Americans (2001); Wendy Ng , Japanese American Internment During World War II: A History and Reference Guide 38 (2002); Morton Grodzins , Americans Betrayed: Politics and the Japanese Evacuation (1949). In June 1942, when Webb argued Regan v. King before the District Court, all of the voters whose rights were at issue in the suit were being held by military authorities, most of them at the Tanforan Assembly Center in nearby San Bruno.79Reporter’s Transcript, supra note 7, at 15-16. Almost all of them would be sent to the Central Utah Relocation Center, also known as Topaz.80 See Konrad Linke, Tanforan (Detention Facility) , Densho Encycl. (June 11, 2025, at 19:59 ET), https://encyclopedia.densho.org/Tanforan_(detention_facility)/ [https://web. archive.org/web/20251027231633/https://encyclopedia.densho.org/Tanforan_(detention_ facility)/] (noting that “98 per cent of the 7,824 Japanese Americans in Tanforan who were transferred to ‘relocation centers’ were sent to the Central Utah WRA camp also known as Topaz.”).

It would be a mistake, however, to see the cases as simply one more manifestation of wartime hysteria. They also represented the resurrection of an earlier effort by anti-Japanese groups in California to strip Japanese Americans of citizenship. The initial phase of that effort had begun in 1919 in the wake of another lawsuit initiated by Webb (who was then the state attorney general): People v. Harada. 81People v. Harada, No. 7751 (Super. Ct. Riverside Cnty. 1916). Webb had brought the Harada action as a test case aimed at expanding racial restrictions on property ownership to encompass the U.S.-born children of Asian immigrants. The case concerned the reach of the California Alien Land Law, a statute drafted by Webb and enacted by the California state legislature in 1913.82California Alien Land Law of 1913, ch. 113, 1913 Cal. Stat. It barred noncitizens from owning property if they were not “eligible to citizenship.”83 Id.

That phrase – “eligible to citizenship” – functioned as a kind of code in the early twentieth century.84On the history of the alien land laws, see Keith Aoki, No Right to Own? The Early Twentieth-Century “Alien Land Laws” as a Prelude to Internment , 40 B.C. L. Rev. 37 (1998); Rose Cuison Villazor, Rediscovering Oyama v. California : At the Intersection of Property, Race, and Citizenship , 87 Wash. U. L. Rev. 979, 992 (2010); Bruce A. Castleman, California’s Alien Land Laws , 7 W. Legal Hist. 25, 34 (1994); Charles H. Sullivan, Alien Land Laws: A Re-Evaluation , 36 Temp. L.Q. 15 (1962); Dudley O. McGovney, The Anti-Japanese Land Laws of California and Ten Other States , 35 Calif. L. Rev. 7, 43 (1947). Leveraging the racial bar contained in the naturalization statute, it provided an ostensibly race-neutral cover for what was universally understood to be a racial bar. The Alien Land Law was aimed in particular at barring land ownership by Japanese immigrants, who had begun arriving in California in higher numbers at the turn of the century and had become the primary target of racial nativism on the Pacific Coast.85 See Daniels , supra note 71, at 16-30 (tracing the history of the Japanese exclusion movement).

Those targeted by the Alien Land Law found several ways to circumvent it; one was by purchasing land in the name of their U.S.-born (Nisei) children. This was the strategy pursued by Jukichi and Ken Harada, who bought property in 1915 in Riverside, California, in the name of their three youngest children, nine-year-old Mine, five-year-old Sume, and three-year-old Yoshizo.86For a detailed account of the case and of the Harada family, see Mark Howland Rawitsch , The House on Lemon Street: Japanese Pioneers and the American Dream (2012); see also Castleman, supra note 84, at 35-37 (discussing the Harada case). Webb’s office brought suit to confiscate the Haradas’ property, taking the position that any attempt to use U.S.-born children to avoid the restrictions in the Alien Land Law made the ownership invalid.87 See Anti-Alien Land Law Does Not Apply to Minor of Japanese Parentage Born in California , Recorder (S.F.), Mar. 2, 1916, at 1, 5. In April 1919, a Superior Court judge in Riverside County ruled in the Haradas’ favor, holding that the purchase of the property in the name of the Harada children was lawful and that “[t]he political rights of American citizens are the same, no matter what their parentage.”88People v. Harada, No. 7751 (Super. Ct. Riverside Cnty. 1916). The case was not appealed. The California Supreme Court later held that a 1920 amendment to the Alien Land Law, which prevented parents who were ineligible to citizenship from serving as guardians for their children for the purpose of land purchases, was unconstitutional. In re Estate of Yano, 188 Cal. 645, 656 (1922).

The state’s defeat in Harada led Webb and other opponents of Japanese immigration to attempt to strengthen the language of the Alien Land Law.89On the attempt to strengthen the Alien Land Law through a 1920 ballot measure, see Aoki, supra note 84, at 56-63. It also led them to call for stripping Asian Americans of birthright citizenship, a campaign that they pursued through a series of proposed constitutional amendments. In a speech to the Sacramento Chamber of Commerce on August 24, 1919, newspaper publisher and prominent exclusionist V.S. McClatchy warned that “[t]he white race is helpless against the economic competition and high birth rate and unassimilable character of the Japanese.”90 Jap Menace Put Before Sacramento , S.F. Exam’r , Aug. 24, 1919, at 32. McClatchy proposed a set of actions to preserve white dominance in the United States, including amending the Citizenship Clause to provide “that no child born in the United States of foreign parents shall be considered an American citizen unless both parents are of a race that is eligible to citizenship.”91 Id. In doing so, McClatchy was taking the strategy that had been used in the California Alien Land Law – leveraging the racial exclusions of the naturalization statute as a basis for racially discriminatory state laws – and proposing to apply it to the Fourteenth Amendment itself.

A week later, McClatchy and others met in Sacramento and founded the Japanese Exclusion League, described by one of its founders as being dedicated to “keep[ing] California as a white man’s country.”92 Move to Keep Out Asiatics is Under Way , S.F. Exam’r , Sep. 6, 1919, at 1 (quoting speech by Assemblyman Ivan Parker at founding meeting); Educational Campaign to Halt Japanese Invasion Is Decided Upon at Meeting , Sacramento Bee , Sep. 6, 1919, at 1; Daniels , supra note 71, at 84-85. The League adopted a program that followed the goals McClatchy had outlined in his article and included the passage of a constitutional amendment excluding children of Asian descent from birthright citizenship.93 See Gregory Mason, The ‘Possum and the Dinosaur: Staff Correspondence from California , Outlook (N.Y.), June 16, 1920, at 320 (contemporaneous magazine account of the founding of the League). Some versions of the League platform stated more generally that the League was opposed to “[t]he granting of citizenship, either by birth or naturalization” to “any people incapable for any reason, of assimilating with the white race and of furnishing desirable material for American citizenship.” Platform and Purpose of the Japanese Exclusion League of California (n.d.) (on file with U.C. Santa Cruz, Special Collections and Archives, Noel L. Patterson Papers). The platform soon garnered endorsements from a variety of organizations and the California state legislature,94 See, e.g. , Jap Exclusion is Demanded , S.F. Exam’r , Sep. 7, 1919, at 6 (reporting on an endorsement by the California State Dairyman’s Association); Am. Legion , supra note 72, at 37-38 (resolution by the American Legion); Two Anti-Alien Resolutions Are Voted by Senate , Sacramento Bee , Apr. 5, 1923, at 16 (reporting on a resolution by the California State Senate); Assembly Adopts Resolution for Barring Aliens , Sacramento Bee , Mar. 26, 1 923, at 1 (reporting on a resolution by the California State Assembly). and by the end of the year, Senator Wesley Jones of Washington introduced an amendment in the Senate along the lines McClatchy had suggested. The amendment would have altered the first sentence of the Fourteenth Amendment to provide that “[n]o child hereafter born in the United States of foreign parentage shall be eligible to citizenship in the United States unless both parents are eligible to become citizens of the United States.”95S. Con. Res. 18, 66th Cong., 59 Cong. Rec. 40 (1919). Representative John Raker of California introduced a parallel resolution in the House.96H.R.J. Res. 255, 66th Cong., 59 Cong. Rec. 214 (1919). The following month, Senator James Phelan of California proposed his own amendment. Dispensing with euphemisms, Phelan sought to change the first sentence of the Fourteenth Amendment to grant citizenship to “[a]ll persons born in the United States and subject to the jurisdiction thereof whose parents are white persons, Africans, American Indians, or their descendants.”97S.J Res. 144, 66th Cong., 59 Cong. Rec. 1815-16 (1920).

When these various proposals failed to make it out of committee, further attempts (equally unsuccessful) followed in 1921.98 See S. Con. Res. 2, 67th Cong., 61 Cong. Rec. 424 (1921). In April of that year, members of Congress from eleven Western states met to discuss plans to build support for a constitutional amendment, as well as to strengthen the alien land laws and seek a federal exclusion act.99 Westerners Unite to Curb Japanese , N.Y. Times , Apr. 21, 1921, at 17. The leadership of the campaign remained in northern California, centered around Webb and McClatchy, along with Phelan, who was at the time campaigning for reelection under the slogan “Keep California White.”100 See Erika Lee , America for Americans: A History of Xenophobia in the United States 189-96 (2019) (discussing James Phelan’s 1920 campaign and his political career).

The League temporarily halted its campaign for a constitutional amendment in 1923 in order to focus on securing a federal law excluding Japanese immigrants from the United States. After it achieved that goal with the passage of the Johnson-Reed Act of 1924,101Immigration (Johnson-Reed) Act of 1924 , Pub. L. 68-139, 43 Stat. 153. it held off on returning to the constitutional amendment in favor of other priorities.102 See Progress Report, Cal. Joint Immigr. Comm. (Dec. 17, 1925) (on file with U.C. Berkeley, Bancroft Library, James D. Phelan Papers, Carton 8, Folder 15) (discussing the decision not to return to the campaign for amendment while seeking to counter attempts to roll back the exclusion provisions in the 1924 Act). On the history of efforts to amend the Japanese exclusion provisions of the 1924 Act, see Lon Kurashige , Two Faces of Exclusion: The Untold History of Anti-Asian Racism in the United States 146-47 (2016); Izumi Hirobe , Japanese Pride , American Prejudice: Modifying the Exclusion Clause of the 1924 Immigration Act 67-148 (2001). Now operating as the California Joint Immigration Committee (CJIC)103On the history of the CIJC, see Natalia Molina , How Race is Made in America : Immigration , Citizenship , and the Historical Power of Racial Scripts 53-58 (2014); Hirobe , supra note 102, at 14-17; Grodzins , supra note 78, at 44-47. – a group comprised of Webb, McClatchy, Phelan, and representatives of five statewide groups104The member organizations were the California branch of the American Legion, the California State Federation of Labor, the Grange, and the Native Sons of the Golden West. See Hirobe , supra note 102, at 15-16. – the organization pivoted to a variety of other issues.105Those issues included advocating for federal policies that would racially bar Mexican immigrants from naturalization; opposing statehood for Hawai’i on the grounds that its large proportion of non-white residents made it unsuitable for statehood; opposing proposed amendments to the 1924 Immigration Act that would have allowed for the admission of small numbers of Japanese immigrants; and seeking to remove material from California textbooks deemed too favorable in its portrayal of Japanese immigrants. See, e.g. , Letter from V.S. McClatchy, Exec. Sec’y, Cal. Joint Immigr. Comm., to R.H. Fouke (June 30, 1936) (on file with U.C. Berkeley, Bancroft Library, Japanese American Evacuation and Resettlement Records) (regarding combatting efforts to create exceptions to the 1924 Act); Press Release, Cal. Joint Immigr. Comm., Japanese Propaganda in American Public Schools (Feb. 5, 1935) (on file with U.C. Berkeley, Bancroft Library, Japanese American Evacuation and Resettlement Records); Press Release, California Joint Immigr. Comm., Hawaiian Statehood and Dual Citizenship (Nov. 14, 1940) (on file with U.C. Berkeley, Bancroft Library, Japanese American Evacuation and Resettlement Records). For a discussion of attempts to bar Mexicans from naturalization, see Molina , supra note 103, at 53-58. To keep the question of birthright citizenship in play, the CJIC developed a campaign to prohibit dual citizenship.106For discussions of opposition to dual citizenship more generally, see Peter J. Spiro , At Home in Two Countries: The Past and Future of Dual Citizenship 22-38 (2016); David A. Martin, The United States and Dual Nationality, Past and Future , 24 Def. Alien 14, 15 (2001). Its pamphlets accused Nisei of having divided loyalties and emphasized the fact that Japanese citizenship law, until 1924, provided automatic Japanese citizenship for a child born abroad to a Japanese father.107 See, e.g. , V.S. McClatchy , America and Japan: Their Treatment of Foreigners and Resulting Conditions 14 (1925) (“The United States is the only nation in the world which confers the great privilege of citizenship upon all children born to aliens within its borders, and entirely regardless of the fitness or desire of the recipients for citizenship when they shall reach majority. The grave consequences following operation of this provision of our National Constitution are seen in the case of the Japanese.”) The Japanese law governing citizenship was amended in 1916 to permit Japanese citizens born abroad to retroactively renounce their Japanese citizenship, and was amended further in 1924 to provide citizenship by descent only if a parent applied for citizenship within fourteen days of the child’s birth . Eric L. Muller , American Inquisition: The Hunt for Japanese American Disloyalty in World War II 11-12 (2007). The CJIC contended that the amendments were not sufficient, because they required anyone born before 1924 to formally renounce their citizenship . McClatchy , supra , at 15.

The prominence of the CJIC declined after McClatchy’s death in 1938,108For a discussion of the declining influence of the CJIC, see Grodzins , supra n ote 78, at 10-11 (1949). but in the wake of the U.S. declaration of war on Japan in 1941, the members of the CJIC sensed an opportunity to regain the organization’s momentum. At their first meeting after Pearl Harbor, one member remarked that “the Committee has received more active support and more general support in the last month than it has received in the last thirty years of its existence.”109Meeting of the California Joint Immigration Committee, Feb. 7, 1942, at 6 (transcript on file with Univ. of Berkeley, Japanese American Evacuation and Resettlement Records, 1930-1974) [hereinafter CJIC Feb. 7 Meeting]. Another encouraged the group to take action, commenting, “This is our time to get things done that we have been trying to get done for a quarter of a century.”110 Id .

B. Birthright Citizenship, Earl Warren, and the Wartime Incarceration of Japanese Americans

The CJIC met on February 7, 1942, two months after Pearl Harbor and shortly before the issuance of the executive order that would pave the way for the forced relocation and incarceration of Japanese Americans. The meeting began with a discussion about resuming the organization’s efforts to strip birthright citizenship from dual citizens. Webb, who served informally as in-house counsel for the organization, discouraged this proposal, warning that “[t]he deprivation of a constitutional citizenship is not an easy matter.”111 Id . at 15. Dual citizenship was a frequent focus of other anti-Asian groups as well. A few weeks earlier, the California Department of the American Legion (headed by Fisk) had passed a resolution demanding that “all Japanese who are known to hold dual citizenship . . . be placed in concentration camps.” Jacobus tenBroek , Edward N. Barnhart & Floyd W. Matson , Prejudice , War , and the Constitution: Causes and Consequences of the Evacuation of the Japanese Americans in World War II 79 (1968). That prompted others to propose that the Committee pursue a constitutional amendment to strip dual nationals of their U.S. citizenship.112CJIC Feb. 7 Meeting, supra note 109, at 15-17. Webb, however, had other ideas: he argued that the organization should ignore citizenship and instead seek the immediate removal of anyone of Japanese ancestry from all coastal areas. “It isn’t a question of place of birth,” he argued. “[I]t is a racial question whether they are Japanese or not.”113 Id. at 27.

By that point, Earl Warren had walked into the meeting. Warren had succeeded Webb as attorney general in 1938. He would soon be elected governor of California, and in 1953 he would become Chief Justice of the U.S. Supreme Court. In February 1942, he was already cultivating a national reputation. Unlike Webb, who loudly espoused racist views throughout his time in office, Warren gave speeches urging racial tolerance.114One year before Pearl Harbor, in a speech to the Associated Farmers convention, Warren urged listeners to remember: In his prior position as District Attorney of Alameda County, he had gone after the Ku Klux Klan.115Charles Wollenberg, “Dear Earl”: The Fair Play Committee, Earl Warren, and Japanese Internment , 89 Cal. Hist. 24, 28 (2012). He was, however, also a longtime member of his local chapter of the Native Sons of the Golden West, one of the groups most actively involved in the Japanese exclusion movement.116On the history of the Native Sons, see Daniels , supra note 71, at 85; Grodzins , supra note 78, at 48-50; He had been profoundly shaped by mentors such as Senator Hiram Johnson and other California progressives who were, as legal scholar Sumi Cho has put it, “as decidedly anti-Asian as they were anti-monopoly.”117Sumi Cho, Redeeming Whiteness in the Shadow of Internment: Earl Warren, Brown , and a Theory of Racial Redemption , 40 B.C. L. Rev. 73, 86-87 (1998).

Warren had a complicated relationship with the CJIC. In 1938, a few days before he was sworn in as attorney general, he had attended a meeting at which the Committee voted to invite him to membership in his official capacity as attorney general, with Webb remaining on in a personal capacity.118Minutes of Meeting, Cal. Joint Immigr. Comm. (Dec. 28, 1938) (on file with U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18). After receiving an explanation of the Committee’s work from Webb, Warren accepted the offer. Warren could not have been under any illusion about what he was getting into – the Committee’s positions were well known. Any conceivable ambiguity would have been cleared up three weeks later, when Warren received a handwritten welcome note from Charles Goethe, a wealthy eugenicist who was a member of the CJIC. Goethe sent the note from the Halukelani Bungalows by the beach in Waikiki. “It is good to feel you are carrying on General Webb’s contribution,” Goethe wrote to Warren, telling him that as the new attorney general, he was now “the key man” in the work of the Committee.119Letter from Charles Goethe to Earl Warren, Att’y Gen., Cal. (Jan. 18, 1939) (on file w ith U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18). Noting that forty-eight percent of the population of Hawai’i was of Japanese descent (a frequent preoccupation of the CJIC), Goethe told Warren that “[o]ne only holds permanently what one holds racially,” underlining the word “racially” three times. “After all, the racial instinct is deep-seated. Therefore you will be doing the immensely popular as well as the statesmen like thing in continuing General Webb’s work.”120 Id . Warren responded that he appreciated Goethe’s “expression of good will and also the interest in the work of the Joint Immigration Committee.”121Letter from Earl Warren, Att’y Gen., Cal., to Charles Goethe (Feb. 11, 1939) (on file with U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18).

Warren’s name was added to the group’s letterhead, but he did not attend the next meeting, and at the meeting after that, he announced that he was resigning his membership and would continue only in an advisory capacity.122Minutes of Meeting, Cal. Joint Immigr. Comm. (Aug. 31, 1939) (on file with U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18). The Committee accordingly moved him off the letterhead, but informed him that he would continue to receive copies of all documents and notices.123Letter from Dorothy Kaltenbach, Sec’y, Cal. Joint Immigr. Comm., to Earl Warren, Att’y Gen., Cal. (Nov. 21, 1939) (on file with U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18). Warren thanked the Committee for understanding “that it would be better for all concerned” if he stepped down, and emphasized that he remained “interested in the Alien Land Law and other matters to which your Committee directs its attention and . . . shall be willing to consult with [the Committee] at anytime on these and kindred matters.”124Letter from Earl Warren, Att’y Gen., Cal., to Dorothy Kaltenbach, Sec’y, Cal. Joint Immigr. Comm. (Dec. 7, 1939) (on file with U.C. Berkeley, Bancroft Library, Robert W. Kenny Papers, Box 18). Thus, he was present at the February 1942 meeting not as a member, but as one of several invited guests.

In early 1942, Warren was emerging as one of the most influential voices supporting the incarceration of Japanese Americans.125 See Frank F. Chuman , The Bamboo People: The Law and JapaneseAmericans 151 (1981). Many accounts of Warren’s career have underplayed his role in Japanese removal and incarceration. See Cho, supra note 117, at 77-86 (critiquing secondary literature on Warren). Sumi Cho and Charles Wollenberg provide correctives to this narrative. See id. at 86-105; Wollenberg, supra note 115. He spent the months after Pearl Harbor heavily engaged in discussions with local, state, and federal law enforcement and military officials about alleged (but never substantiated) patterns of Japanese landholding near sensitive locations such as airports, railroad tracks, and military installations.126Cho, supra note 117, at 90-103. He also initiated a project to map property ownership, and revived enforcement of the Alien Land Law.127 Id. The mapping project, although methodologically flawed,128 Id. was influential in swaying public opinion nationwide, leading figures like Walter Lippmann – the nation’s most renowned newspaper columnist at the time – to call for mass evacuation.129 Id. at 101-02 (stating that “[t]he mapping project so impacted renowned newspaperman Walter Lippmann that it formed the basis for Lippmann’s influential February 12 syndicated column on the military necessity of internment” and that Lippmann’s column influenced other journalists, federal officials, and President Roosevelt).

At the February meeting, Warren concurred with Webb, urging those gathered to pursue a strategy based on race, rather than legal status. He argued that a focus on dual citizens could have negative consequences for Americans of German and Italian descent, whom he described as “born to the soil” and “of the same race.” (“[T]hey are blended in entirely,” he argued. “It is an entirely different situation.”)130CJIC Feb. 7 Meeting, supra note 109, at 37-38. To emphasize his point, he criticized a recent decision by the state Personnel Board (one that the CJIC had advocated for) to bar both naturalized citizens from enemy nations and their U.S.-born descendants from civil service jobs. “Think what that means,” he told the others. “Think how many people there are in California whose fathers and mothers were born in Germany or in Italy.” Id. at 39-40. Warren’s ostensible concerns about the spillover effect of this policy on white birthright citizens, it should be noted, had little basis in fact; the actual Personnel Board policy, which Warren read aloud at the meeting, specified that the Board would “start out by applying the action to persons with Japanese names.” Id. at 41. He also urged the members of the Committee to stop thinking in terms of political and legislative strategies, which would not yield results quickly enough:

We have to recognize . . . that native-born Japanese . . . have certain rights the same as you and I have them so long as the United States Government recognizes their citizenship to be the same as ours. With that we cannot interfere until Congress either makes some different approach to it or until our Constitution is changed. Those things take time.131 Id. at 36.

Warren urged the Committee to push instead for a military solution. The military, he argued, had the authority to evacuate anyone, regardless of citizenship:

I can’t see any way that [the forced relocation of U.S. citizens] can be done in a civil way. There is no way that our courts could permit it to be done, but the Army that is charged with the security of this combat zone has the right to do it. It has the right to tell me to get back 200 miles if it wants to do it, and as a good American citizen I have no right to complain. Now, if a good American citizen cannot complain, I don’t see why the Japanese should complain.132 Id. at 36-37.

Warren intimated that the military authorities would “not be averse to having pressure applied in order to show the rest of the country just what their danger is here.”133 Id. at 48. (As many accounts have shown, and as Warren undoubtedly knew at the time, federal officials were, in fact, quite divided on the question of what actions could be taken against U.S. citizens; political pressure mobilized by Warren and others was influential in swaying them toward incarceration.)134 Milton S. Eisenhower , The President is Calling 99-110 (1974) (on divisions within the Roosevelt administration); Cho, supra note 117, at 90-105 (discussing Warren’s influence). Following Warren’s intervention, the Committee resolved to focus its immediate efforts on a mass evacuation policy that made no distinctions along lines of citizenship status, and also to continue working on the issue of dual citizenship over the long term.135CJIC Feb. 7 Meeting, supra note 109, at 47. Following the meeting, the group issued a public statement urging federal authorities to declare the Pacific coastal region a combat area and to ensure that the “Japanese, including Japanese citizens of the United States . . . be removed as quickly as possible from said zone.”136 See Ouster of Citizen Japanese is Urged by State Group , Fresno Bee , Feb. 16, 1942, at 1.

C. The Decision to Litigate

Webb and others had previously sought to amend the Citizenship Clause, but they had never contemplated a legal challenge to Wong Kim Ark , and the idea was not mentioned at the February meeting. By April, however, the Committee arrived at a plan to bring a lawsuit to do precisely that.137 See infra notes 173-88 and accompanying text. The decision to file the complaints in Regan v. King and Fisk v. Wade was a direct response to calls within Congress for the Supreme Court to overturn Wong Kim Ark .138 See infra notes 155-69 and accompanying text. Those calls occurred soon after the CJIC’s February meeting.139 Id. They were a response to the airing of significant doubts within the Roosevelt administration regarding the legality of incarcerating Japanese Americans based solely on their ethnicity.140 See infra notes 142-51 and accompanying text.

In the immediate aftermath of Pearl Harbor, federal authorities had begun arresting Japanese immigrants (Issei) , along with smaller numbers of Germans and Italians, as alleged threats to national security. By mid- February, the government had detained 879 Issei in Hawai’i and over two thousand Issei on the mainland (almost ten percent of the adult males within Japanese immigrant communities in Pacific Coast states).141 Peter Irons , Justice at War: The Story of the Japanese American Internment Cases 19 (1983). When such arrests began, federal officials did not give serious consideration to taking mass action against U.S. citizens of Japanese descent. On December 26th, when Lieutenant General John DeWitt, Commander of the Western Defense Command, was informed that the Los Angeles Chamber of Commerce was urging that all residents of the city of Japanese descent, citizen and noncitizen, be evacuated, he dismissed the idea, saying, “An American citizen, after all, is an American citizen.”142 Eisenhower , supra note 134, at 101. By the end of January, however, DeWitt’s position would change, influenced heavily by meetings with California elected officials.143 Id . at 103-04.

Even as DeWitt’s position was shifting, attorneys within the Department of Justice, including Attorney General Francis Biddle, remained staunchly opposed to evacuating Nisei, engaging in tense discussions with staff within the War Department.144 Id. at 105 (stating that in early February 1943, “the situation [among federal officials] was confused, and it could have gone either way,” with Biddle and some others resisting mass evacuation, DeWitt wavering, and others favoring mass evacuation). When California Congressman Leland Ford wrote to Cabinet members demanding that all ethnic Japanese be placed in inland concentration camps,145 Id. at 102. Biddle wrote back, “Unless the writ of habeas corpus is suspended, I do not know of any way in which Japanese born in this country and therefore American citizens could be interned.”146 tenBroek , Barnhart & Matson , supra note 111, at 312 (quoting Letter from Francis Biddle, Att’y Gen., to Leland Ford, U.S. Rep., Cal. (Jan. 24, 1942)). In a memorandum to the president, Biddle used even stronger words: “American born Japanese, being citizens, cannot be apprehended or treated like alien enemies.”147Amanda L. Tyler, Courts and the Executive in Wartime: A Comparative Study of the American and British Approaches to the Interment of Citizens During World War II and Their Lessons for Today , 107 Cal. L. Rev. 789, 832 (2019) (quoting Memorandum from Francis Biddle, Att’y Gen., to Franklin D. Roosevelt, President (Jan. 30, 1942)). On February 1st, Biddle proposed sending out a joint press release on behalf of the Department of Justice and the War Department, stating that the departments were “in agreement that the present military situation does not at this time require the removal of American citizens of Japanese race.”148 Eisenhower , supra note 134, at 104-05.

The press release was not distributed, however, due to division within the military. Although Secretary of War Henry Stimson still had reservations, DeWitt and others now supported mass evacuation.149 Id. at 101-12. DeWitt sent a memo on February 14th recommending the evacuation and incarceration of all those of Japanese descent along the entire West Coast.150 Robinson , supra note 78, at 106. The memo, written for DeWitt by Col. Karl R. Bendetsen, an attorney who worked in the Provost Marshal General’s office, stated that “the Japanese race is an enemy race and while many second and third generation Japanese born on United States soil, possessed of United States citizenship, have become ‘Americanized,’ the racial strains are undiluted.”151Natsu Taylor Saito, Interning the “Non-Alien” Other: The Illusory Protections of Citizenship , 68 L. & Contemp. Probs. 173, 177 (2005) (citing U.S. Congress, Commission on Wartime Relocation and Internment of Civilians, Personal Justice Denied: Report of the Commission on Wartime Relocation and Internment of Civilians 66 (1982)). The day before the memo was finalized, Walter Lippmann’s highly influential opinion piece appeared in newspapers nationwide under the headline “The Fifth Column on the Coast.”152Walter Lippmann, The Fifth Column on the Coast , Wash. Post , Feb. 12, 1942, at 14 (the column was syndicated and appeared in newspapers across the country). In the days immediately following, both Stimson and Biddle dropped their opposition.153 tenBroek , Barnhart & Matson , supra note 111, at 111. On February 19th, President Roosevelt issued Executive Order 9066, authorizing the Secretary of War to designate military areas and to exclude people from such areas at his discretion, and over the following months, a series of military orders directed thousands of Japanese Americans, along with Japanese immigrants, to report for “relocation.”154Exec. Order No. 9066, 7 Fed. Reg. 1407 (Feb. 25, 1942). On the implementation of the policy, see Robinson , supra note 78, at 127-39; NG, supra note 78, at 21-27; Grodzins , supra note 78.

When questions about the legality of rounding up U.S. citizens of Japanese descent surfaced within the administration, a few voices in Congress began calling to overturn Wong Kim Ark . Congressman John Rankin, a staunch segregationist from Mississippi, gave a speech in the House of Representatives on February 18th, in which he proclaimed that the conflict with Japan was a “race war” and called for “get[ting] rid of every Japanese whether in Hawaii or on the mainland. . . . Damn them! Let us get rid of them now.”15588 Cong. Rec. 1419-20 (1942). He followed up with more detailed remarks on February 23rd, delivering a speech entitled “Concentration Camps for Japanese.”15688 Cong. Rec. 768 (1942). In the speech, Rankin acknowledged that “[i]t is being argued in some quarters that we do not have the constitutional right to handle the Japanese who are born in this country,” and that some were taking “the position that these Japanese are American citizens and entitled to the same rights as are the descendants of the signers of the Declaration of Independence.”157 Id . at 769. He emphatically disputed that contention, proclaiming, “These Japanese are not citizens of the United States and never can be.”158 Id . Rankin acknowledged that “a different position was once taken by the Supreme Court” and then quoted at length from the Wong Kim Ark dissent.159 Id.

Another Southern Democrat, Senator Tom Stewart of Tennessee, presented similar arguments in the Senate. On the same day that President Roosevelt issued Executive Order 9066, Stewart introduced a bill directing the Secretary of War to “provide for taking into custody certain persons who are citizens or subjects of, or owe allegiance to, any nation or country with which the United States is at war.”16088 Cong. Rec. 1440 (1942). The legislation may have been worded broadly, but its aim was racially specific. When Stewart spoke of the bill a few days later on the floor of the Senate, he described it as a bill to take into custody “any person who is considered by the laws of any foreign power with whom we are at war to be a citizen of such nation and is of a race or nationality ineligible to naturalization in the United States.”16188 Cong. Rec. 1682 (1942). (By June, Stewart would be describing the bill as authorizing the detention of “all Japanese in America and in the island possessions of America, regardless of whether or not they were American born.”162S. 2293, 77th Cong., 88 Cong. Rec. 5427 (1942).) Speaking on the Senate floor on February 26th, Stewart acknowledged that the bill was “directed at the Japanese” and noted that it “raises directly the question of its constitutionality under the fourteenth amendment of the Constitution and, specifically, the first clause thereof . . .”16388 Cong. Rec. 1682 (1942). Stewart then quoted extensively from the dissent in Wong Kim Ark and stated that he was “calling attention to this Wong Kim Ark case because it ought to be reversed or overruled.”164 Id . at 1682-83.

Stewart’s call to overturn Wong Kim Ark generated significant media coverage,165 Bill Proposed to Cancel Nisei Citizenship , Long Beach Sun , Mar. 13, 1942, at 1; Move Starts to Ban Jap Citizenship , Oakland Trib. , Mar. 12, 1942, at 1; Citizenship to Japs Assailed , Knoxville News-Sentine l, Mar. 1, 1942, at 5; Offers Bill to End Jap Citizenships , Daily News (N.Y.), Mar. 13, 1942, at 20. and on March 15th, he followed up with an announcement that he had invited the governors of six states – California, Washington, Oregon, Arizona, Nevada, and Texas – to Washington D.C. to testify in support of his bill.166 Governors of Six States Asked to Confer on Rigid Alien Bill , Richmond Times-Dispatch , Mar. 16, 1942, at 8. He acknowledged that there was “some doubt now as to authority of the War, Justice and other departments to arrest and intern [Japanese Americans]” and promised that his bill would remedy this uncertainty.167 Id . The governor of New Mexico, although not among the governors invited by Stewart, also voiced support for challenging the validity of Wong Kim Ark ,168 See Nackenoff & Novkov , supra note 51, at 130; Robin Dale Jacobson, Daniel Tichenor & T. Elizabeth Durden, The Southwest’s Uneven Welcome: Immigrant Inclusion and Exclusion in Arizona and New Mexico , 37 J. Am. Ethnic Hist. 5, 25-26 (2018). and New Mexico Supreme Court Justice A.L. Zinn went on a round of speaking engagements calling for Wong Kim Ark to be overturned.169 Can Deprive Nisei of Citizenship? , Santa Fe New Mexican , Mar. 14, 1942, at 4; Zinn Says American Born Japs Aliens , Albuquerque J. , Mar. 14, 1942, at 5. One of these speeches was read into the record in the Senate by Senator Edwin Johnson of Colorado. 88 Cong. Rec. 3334 (1942) (reproducing the text of Zinn’s address to the Daughters of the American Revolution).

Anti-Asian groups in California were paying careful attention to these developments. Grizzly Bear , a monthly magazine published by the Native Sons of the Golden West, reproduced both Stewart’s and Rankin’s speeches in full.170John E. Rankin, Japs Not Citizens of the U.S. and Never Can Be , Grizzly Bear , May 1942, at 4; Tom Stewart, Does the U.S. Constitution Make Citizens of Children Born of Japs? , Grizzly Bear , Apr. 1942, at 3. Stewart’s speech, including its call for a lawsuit to overturn Wong Kim Ark , appeared in the April issue, along with a note from the editor remarking pointedly that the speech was being “directed to the attention of the attorney-general and the several district attorneys of California.”171Editorial, Grizzly Bear , Apr. 1942, at 3. The editor’s note made it clear that the land ownership issues that had animated earlier attempts to restrict birthright citizenship were still at play. It argued that if the children of Japanese immigrants were not citizens under the Fourteenth Amendment, it would “be less difficult to recover from [them] all the land, rural and urban, they have obtained through violation or evasion of the California Alien Land Law. Let’s have action, NOW.”172 Id . Questions about land ownership also motivated Webb. See Webb Tells Native Sons of Steps to Revoke Japanese Citizenships , Fresno Bee , May 20, 1942, at 4 (reporting on a speech that Webb delivered to a Native Sons convention, in which he cited the California Alien Land Law and stated that “productivity of the Japanese constitutes a definite threat which must be obviated by a reinterpretation of the constitution or a constitutional amendment.”); see also Robinson with Wu, supra note 11, at 13 n.63 (discussing Webb’s motivation for the lawsuit).

On April 27th, on the heels of the publication of Stewart’s speech, the CJIC approved a resolution to bring an action in federal court to “determine whether native born Japanese are citizens.”173Minutes, Cal. Joint Immigr. Comm. (Apr. 27, 1942) (on file with U.C. Berkeley, Bancroft Library, Japanese American Evacuation and Resettlement Records). Ten days later, Webb filed the complaints in Regan v. King and Fisk v. Wade . Soon afterward, Webb served as the keynote speaker at a convention of the Native Sons, where the assembled members approved the creation of a committee to raise money “to prosecute, and carry through to the Supreme Court of the United States, if necessary, a suit challenging the United States citizenship of the Japanese” and “to draft and sponsor an amendment to the Constitution of the United States which shall have as its object the exclusion of all persons of Japanese ancestry from American citizenship.”174Peter T. Conmy, An Historical Discussion of Citizenship and the Case of Regan v. King (n.d.) (on file with Cal. Hist. Soc’y, Papers of the Native Sons of the Golden West). Warren also addressed the gathering, telling the crowd that he “strongly favored prosecution of the suits.”175 Court Test on Japs Gets Warren O.K. , Oakland Trib. , May 20, 1942, at 15. This is the only documented instance of Warren expressing his support; as historian Greg Robinson has observed, “A fair conclusion is that Warren, who had announced in April his candidacy for governor . . . made a single hedged statement supporting the suit as a necessary profession of faith to retain the political support of the Native Sons, long his chief backers.”176Robinson, Birthright Citizenship , supra note 11. Robinson notes that Warren’s support was “hedged,” in that he backed the litigation but stopped short of backing a constitutional amendment, instead saying that, if the litigation failed, other methods should be studied. Id ; see also Robinson with Wu, supra note 11, at 15 (discussing Warren’s “limited and cautious” support for the litigation).

Although the lawsuits were directed at denying Japanese Americans the right to vote, there is no indication that Webb or any of the others involved in the lawsuits were particularly focused on electoral issues at that moment. Rather, an attack on voting rights provided a convenient vehicle for challenging Wong Kim Ark . Emboldened by wartime anti-Japanese hysteria, the CJIC members’ first instinct had been to renew their attack on dual citizenship. On the advice of Warren, they shifted gears to focus on a military strategy that would be directed at people of Japanese descent without regard to citizenship status. When doubts arose about the legality of subjecting Japanese Americans to such actions, they decided to bring a suit to challenge Wong Kim Ark .

Anti-Asian organizations in California had returned to the question of the Citizenship Clause for several reasons. First, they understood that birthright citizenship once again posed an obstacle (or at least, a potential obstacle) that required dismantling. Just as birthright citizenship had blunted the effects of the Alien Land Law, it now threatened to block plans for relocation and incarceration. Second, they remained focused on the goal that had originally led them to seek a constitutional amendment years before: depriving Japanese immigrants and their U.S.-born children of land ownership.177Editorial, supra note 171, at 3; Editorial, Now is the Time to End It , AppealDemocrat (Marysville, Cal.), Sep. 25, 1942, at 12 (making arguments for deporting Japanese Americans who had shown “sympathy for Japan” and also calling for ending the “abuse of fake land ownership” – a reference to the purchase of land under the name of U .S. citizen children). Although the constitutional amendments that they had proposed in the 1920s had failed to make it out of committee, they believed that the right moment had finally arrived to achieve their goal through litigation. As Webb would note in his argument before Judge St. Sure in June, “[T]he attitude of the Federal Government toward the Japanese Government up to recently was not very favorable, but on the 7th of December, last, I concluded that it was about time that this question should be submitted to the courts of this country.”178Reporter’s Transcript, supra note 7, at 43. December 7th was the date of the Pearl Harbor attack. Third, they understood the value of keeping the matter in the public eye, even if their argument did not prevail. At the February 7th meeting, while discussing the possibility of pursuing a constitutional amendment that would bar dual citizenship, Charles Goethe acknowledged that it would be “a tremendous fight to amend the Constitution.”179CJIC Feb. 7 Meeting , supra note 109, at 16-17. He argued, however, that even an unsuccessful attempt would be valuable:

If we should make a fight of this kind, even though we never win it . . . the very fact that we keep after that month after month and year after year, and we can do it with a very small amount of funds, we would educate the people of the United States to the whole problem of dual citizenship.180 Id.

Goethe understood that the ultimate goal was to get the message out to a broader audience: “If we can go ahead and hammer at this thing week after week and day after day, we will change the attitude of what is practically the whole of the United States except the northern end of California.”181 Id . at 17. The lawsuits, however far-fetched they may have been in their legal arguments, provided a vehicle for “hammer[ing] away” at the legitimacy of Japanese American citizenship. On the day that the complaint was filed, Fisk wrote to a fellow member of the CJIC: “Today, I signed as plaintiff, the legal papers prepared by the General [Webb] – so now we may expect fireworks.”182Letter from James Fisk to V.S. McClatchy, Exec. Sec’y, Cal. Joint Immigr. Comm. (May 7, 1942) (on file with U.C. Berkeley, Bancroft Library, Japanese American Evacuation and Resettlement Records).

Fisk and his collaborators were correct in sensing that the war had created a more receptive audience for their agenda. The ideas that they had been putting forward for decades – that Japanese Americans had divided loyalties and represented a racial threat to the United States – had never been more widely shared. The following year, in Hirabayashi v. United States 183320 U.S. 81 (1943). and Yasui v. United States ,184320 U.S. 115 (1943). the Supreme Court would uphold the imposition of curfews on Japanese Americans. In Korematsu v. United States ,185323 U.S. 214 (1944), abrogated by , Trump v. Hawaii, 585 U.S. 667, 710 (2018). the Court would uphold the orders excluding Japanese Americans from coastal areas, deferring to the military and declining to find that singling out Americans of Japanese ancestry violated the Constitution. A public opinion poll taken in December 1942, while Regan v. King was being litigated, found that a majority of Americans thought that all of the Japanese Americans being held in internment camps should be “sent back” to Japan.186 Amanda Frost , You Are Not American: Citizenship Stripping from Dred Scott to the Dreamers 127 (2021) (citing Louise Merrick Van Patten, Public Opinion on Japanese Americans , 14 Far E. Surv. 207, 207-08 (1945)). Although federal law prohibited renunciation of citizenship during wartime, Congress amended the relevant statute in 1944 to permit such renunciations.187Renunciation Act of 1944, Pub. L. 78-405, 58 Stat. 677. During a three-month period beginning in late 1944, one out of every fourteen U.S. citizens of Japanese descent – 5589 people in all – renounced their U.S. citizenship, many under coercive conditions.188 Donald E. Collins , Native American Aliens: Disloyalty and the Renunciation of Citizenship by Japanese Americans During World War II , at 3 (1985). See also Mae M. Ngai , Impossible Subjects: Illegal Aliens and the Making of Modern America 187-201 (2004) (discussing the renunciation cases); Frost , supra note 186, at 126-134 (same). Many of the renunciants later regained their citizenship. See Charles Wollenberg , Rebel Lawyer: Wayne Collins and the Defense of Japanese American Rights 71-85 (2018).

D. Litigation Before the District Court

At a hearing in June 1942, Webb urged Judge St. Sure to reject the Supreme Court’s holding in Wong Kim Ark and to adopt the position of the dissenting justices. This was not, however, simply a rehashing of the position that the Department of Justice took in the 1890s. Webb’s new strategy was clear right from the start, when he defined the issue before the court as one of seeking to restrict people based on race, and race alone: “Is a member of the Japanese race, born in the United States, a citizen of the United States?”189Reporter’s Transcript, supra note 7, at 23.

In Wong Kim Ark , the government had presented a much broader question to the Supreme Court: “[W]hether a person born within the United States of parents the subjects of a foreign power is a citizen of the United States.”190Motion to Advance at 1, United States v. Wong Kim Ark, 169 U.S. 649 (1895) (No. 904). Wong’s attorneys had stated the question in similarly broad terms: “Are the children born in this country of alien residents not connected with the diplomatic service citizens of the United States?”191Brief of the Appellee at 4, Wong Kim Ark , 169 U.S. 649 (No. 904). Arguing within this framework, the attorneys representing the government had sought to convince the Supreme Court that the Fourteenth Amendment, despite its apparent focus on territorial birth, embodied a rule of international law that recognized only descent, not place of birth, as the basis for citizenship at birth.192 See Erman & Perl-Rosenthal, supra note 22, at 664 (discussing arguments by Wong Kim Ark’s attorneys). Wong Kim Ark’s attorneys, in turn, pointed out to the Court that such a rule would affect not only the children of Chinese immigrants but also the children of European immigrants. 193 Id. The government had been confident that a victory in the case would not pose an obstacle to citizenship for children of European immigrants, because they could easily naturalize.194 See The Wong Kim Ark Case , S.F. Call , Mar. 29, 1896, at 19 (newspaper article in which Collins reported that he sought to have the Supreme Court delay a decision in Wong Kim Ark until after the upcoming election, in order to leave “ample time before another election for the Caucasians who may be disfranchised by the ruling to make good their citizenship.”). Nevertheless, the argument of Wong Kim Ark’s attorneys appeared to resonate with the Court; the majority opinion noted that the government’s reading of the Citizenship Clause would “deny citizenship to thousands of persons of English, Scotch, Irish, German, or other European parentage, who have always been considered and treated as citizens of the United States.”195 Wong Kim Ark , 169 U.S. at 694.

In 1942, Webb offered Judge St. Sure a way to strip Asian Americans of citizenship without harming the children of white immigrants. Rather than grounding his argument in a descent-based principle of citizenship drawn from international law, he grounded it in the history of American racism and its ongoing legal architecture. Webb proposed drawing the same line that he and his collaborators had pitched to Congress as a constitutional amendment two decades earlier: basing a child’s citizenship on the parents’ racial eligibility to naturalize.196Although this was not the line that the government had proposed in Wong Kim Ark , Justice Fuller’s dissent does contain some suggestion that such a line was also contemplated in 1898. Referring to the specifics of Chinese immigration to the United States, Fuller wrote: I think it follows that the children of Chinese born in this country do not, ipso facto, become citizens of the United States unless the fourteenth amendment overrides both treaty and statute. Does it bear that construction; or, rather, is it not the proper construction that all persons born in the United States of parents permanently residing here, and susceptible of becoming citizens, and not prevented therefrom by treaty or statute, are citizens, and not otherwise?

Webb began by mapping the racial dimensions of his project. Although the complaint had framed the question presented as one about the children of Japanese immigrants, he quickly clarified that his argument reached more broadly:

I might add, so that it will not appear I am presenting this thing narrowly, that that question, incidentally, involves races other than the Japanese. In short, that question, as we conceive it to be, involves the citizenship, the right to citizenship of all peoples and all races who do not fall under the characterization or description of white people.197Reporter’s Transcript, supra note 7, at 23.

Anticipating the inevitable next question, he then clarified further:

I might mention, by way of explanation here, when I speak of “white,” I am quite aware that the court has in mind the fact that as a result of the Civil War the gates were opened to the Negro, and the Negroes were included under the Fourteenth Amendment of the Federal Constitution, and also expressly covered by the Fifteenth Amendment to the Federal Constitution, and by the Naturalization Law, as amended in 1870.198 Id. at 24.

How could Webb convince the court to adopt a rule of “white” citizenship that would not exclude Black people? By tying it to the naturalization statute. Acknowledging that the Fourteenth Amendment “brings, of course, into citizenship the colored race, for they were born in this country, and wholly subject to the jurisdiction of the United States,” he then argued that “their status is in nowise involved or concerned” because the Fourteenth Amendment, in his view, “citizenized [sic] all persons born in the United States of parents who were eligible to citizenship.”199 Id. at 26. However, as the Supreme Court itself noted in the Wong Kim Ark decision, at the time of the ratification of the Fourteenth Amendment, Black immigrants were still racially barred from naturalizing, and thus, not all Black people born in the United States were children of parents who were eligible to citizenship. Wong Kim Ark , 169 U.S. at 701-02; see also In re Look Tin Sing, 21 F. 905, 909 (C.C.D. Cal. 1884) (“When [the Fourteenth Amendment] was adopted, the naturalization laws of the United States excluded colored p ersons from becoming citizens, and the freedmen and their descendants, not being aliens, were without the purview of those laws. So the inability of persons to become citizens under those laws in no respect impairs the effect of their birth, or of the birth of their children, upon

Webb then attempted an inversion of the strategy that Wong Kim Ark’s attorneys had used. They had argued that the government’s proposed rule would harm the children of all immigrants, hoping to capitalize on the Court’s hesitance to harm white immigrants. Webb sought to harness racial bias in the opposite direction: by persuading Judge St. Sure that if he followed the rule set forth in Wong Kim Ark , he would be leaving the door open not just to the children of Japanese immigrants but to millions of racialized others. Webb offered the court an alternative construction of the Fourteenth Amendment that “would exclude from its operation all colored races, all colored persons except the Negro . . . .”200Reporter’s Transcript, supra note 7, at 27. This construction, Webb promised,

excludes three-fifths of the world’s population; it excludes the Hindus, the Chinese, the Japanese, the Hottentots, and the inhabitants of the islands of the Pacific, while the construction which gives citizenship to the Japanese, includes all the peoples of the world who chance to be born within the territory of the United States.201 Id.

Descending even further into racist tropes, Webb warned that the Wong Kim Ark decision “extends citizenship automatically to all people of the world, and possibly if the Darwin theory of human origin be correct it might include the chimpanze [sic], of Africa, if it cared to be one of our citizens.”202 Id. at 39-40.

Webb’s vision was an unabashed expression of white nationalism, and he had no trouble grounding it in then-current U.S. statutes and case law. He walked Judge St. Sure through the various times that Congress had enacted statutes that restricted naturalization to white immigrants and later, in 1870, to white and Black immigrants.203 Id. at 29-32. He cited the Supreme Court’s decisions in Ozawa v. United States 204Ozawa v. United States, 260 U.S. 178 (1922). and United States v. Thind ,205United States v. Thind, 261 U.S. 204 (1923). in which the Court held, respectively, that Japanese and Indian immigrants were racially ineligible for naturalization. He then quoted a passage from Thind that linked the racial bar on naturalization to the exclusion of Asian immigrants in the Immigration Act of 1917: “[I]t is not likely that Congress would be willing to accept as citizens a class of persons whom it rejects as immigrants.”206Reporter’s Transcript, supra note 7, at 39. Although Webb did not provide the citation at oral argument, the passage is from Thind , 261 U.S. at 215. The implication of Webb’s argument was clear: why should that principle, which had already found favor at the Supreme Court, apply only to naturalization and not to birthright citizenship as well?

Webb also quoted liberally from the Wong Kim Ark dissent, including the dissent’s statement that

[t]he true bond which connects the child with the body politic is not the matter of an inanimate piece of land, but the moral relations of his parentage. The place of birth produces no change in the rule that children follow the condition of their fathers, for it is not naturally the place of birth that gives rights, but extraction.207Reporter’s Transcript, supra note 7, at 35 (quoting United States v. Wong Kim Ark, 169 U.S. 649, 708 (1898) (Fuller, J., dissenting)).

The government had argued in Wong Kim Ark that this principle should be applied to all children whose parents were not U.S. citizens. Webb’s innovation was to shift the status in question from citizenship itself to the racially coded question of eligibility for citizenship.

The final element of Webb’s argument sounded as if it were lifted from the Dred Scott decision: “This country, your Honor, was settled by the white race.”208 Id. at 27. In his view, the nation’s white founders “had no contact with any other people, they had no thought of any other people; they were not seeking to build a new world and government for any people other than the white people, their own kind.”209 Id. He then provided his own gloss on the preamble to the Constitution:

“We, the People of the United States” – it is the same white [sic] that I have been talking about, these same Caucasians, if your Honor please – “in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America.”210 Id. at 40 (quoting U.S. Const. pmbl.).

Webb appealed to Judge St. Sure to interpret the Citizenship Clause in line with this vision of white nationhood. He suggested that the “admission to this country of Caucasians from any country” might be in line with the goals expressed in the preamble, but claimed that “it requires no proof to show that the admission of Japanese to citizenship does not comply and conform to the purposes to be achieved by that instrument.”211 Id. at 40. “Already, in a frantic effort to provide for the country’s defense, we have incurred obligations in excess of two hundred million dollars to segregate them from our citizens fighting upon land and upon sea, to prevent their fighting us behind the line,” Webb argued.212 Id. at 40-41. “Does any human being imagine for a moment that the admission of these people to this country in the activities, not only our commercial activities, but military activities, can promote the general welfare?”213 Id. at 41.

In sharp contrast to Webb’s rambling argument, the response from Chief Deputy City Attorney Walter Dold was brief and to the point. Dold uttered only six sentences. Noting that Webb’s argument “has come a little too late,” he pointed out that there were two Supreme Court cases directly on point. “I would like to cite them to the Court,” he continued, “and that is all there is to it, as far as we are concerned.”214 Id. at 42. Historian Greg Robinson and legal scholar Frank H. Wu have suggested that Dold’s reticence and the absence of Chief City Attorney John J. O’Toole at the hearing may have stemmed from behind-the-scenes cooperation between the City Attorney’s office and Webb. See Robinson with Wu, supra note 11, at 22 (citing a contemporaneous statement by ACLU attorney Ernest Besig that the City Attorney’s office was cooperating with Webb). One of the cases was, of course, Wong Kim Ark . The other was Morrison v. California , a 1934 case concerning an appeal of a criminal conviction for conspiracy to violate the California Alien Land Law, in which the Supreme Court had stated that “[a] person of the Japanese race is a citizen of the United States if he was born within the United States.”215Morrison v. California, 291 U.S. 82, 85 (1934).

After Dold’s quick argument, Webb requested time for a rebuttal on Morrison . (Webb, who had litigated Morrison , remarked dryly, “I argued that case in the United States Supreme Court, and succeeded in getting a unanimous opinion against my contention, so I know something about it.”)216Reporter’s Transcript, supra note 7, at 42 He argued that Morrison should not be cited as a precedent on birthright citizenship because the issue had not been in dispute. “It is true that Justice Cardozo, in speaking of it, did say that Japanese born in this country are citizens, and this lost the case,” Webb conceded, “but that question was not argued, not presented, not considered. We admitted that Japanese born in this country were citizens.”217 Id. at 43.

This was an interesting admission from an attorney who was now arguing exactly the opposite. Webb sought to explain the about-face: “We have always admitted it,” he said. “We challenge it here for the first time.”218 Id. What accounted for the change? Webb explained that he had “learned in 1922 the decision was wrong.”219 Id. That, presumably, was a reference to Ozawa , which the Supreme Court decided in 1922. The timing did not quite add up, though, because Morrison was not argued until 1933, eleven years after Ozawa was decided. Webb’s next sentence made clear that the change that had propelled him to bring the challenge was not just Ozawa . “I have been intending from 1922, ever since then, to bring an action of this kind in order that that question might be submitted, but the attitude of the Federal Government toward the Japanese Government up to recently was not very favorable [to such a challenge],” Webb explained. That changed, he said “on the 7th of December, last,” – the date of the Pearl Harbor attack – “[when] I concluded that it was about time that this question should be submitted to the courts of this country.”220 Id.

The hearing could have easily ended there, with Webb’s vision of the United States as a white republic countered only by Dold’s brief recitation of the law. There were, however, two other attorneys present, and they were ready to name Webb’s vision for what it was. Attorney Harold Sawyer, representing the National Lawyers Guild as amicus curiae, began his argument with a dramatic opening line: “If you had taken the argument made by General Webb,” Sawyer began, “and substituted the word ‘white’ to Aryan, you would have had the same language as contained in Hitler’s ‘Mein Kampf.’”221 Id. He continued in this vein for the remainder of his argument. “We are fighting a democratic war,” he told Judge St. Sure, “and we cannot do it by adopting fascist technique, and to limit the right to be a citizen to only a selected few of the white race is to destroy the meaning of everything we are trying to do.”222 Id. at 44-45. Charles Garry, also representing the Guild, developed this argument further:

Your Honor, I would like to throw into the question that millions of Americans, as well as some of our Allies, some twenty-six nations who are fighting with us, what would they think if we came out to-day, in the midst of a war, and said that the United States would only recognize Americans who were born white as citizens of the United States.223 Id. at 49.

They followed up a few days later with an amicus brief along the same lines:

We are fighting a war for the preservation of the four freedoms enunciated by President Roosevelt, for the installation of the Atlantic Charter, and for the triumph of democracy over slavery; but if democracy is only to be for the white people, our war aims are meaningless and there is little distinction between them and Hitler’s aim to conquer the world for the German people. The possibility that our war aims could be so limited is revolting to every American citizen.224Memorandum on Behalf of S.F. Chapter of Nat’l Law. Guild as Amicus Curiae at 5, Regan v. King, 49 F. Supp. 222 (N.D. Cal. 1942) (No. 22178-S) (on file with Nat’l Archives, Records of District Courts of the United States, Record Group 21, Civil Case Files (1912-2004)).

The National Lawyers Guild was the only civil rights group represented at the hearing. However, attorney Wayne Collins, who was soon to become one of the central figures in challenging the constitutionality of internment and in restoring the status of those who had renounced U.S. citizenship,225On Wayne Collins’ work on the renunciation cases, see Wollenberg , supra note 188. read a news article about the hearing and quickly drafted an amicus brief on behalf of the ACLU.226Letter from Wayne Collins to A.L. Wirin (Dec. 5, 1942) (on file with U.C. Berkeley, Bancroft Library, Wayne M. Collins Papers). “Petitioner’s counsel argues for a ‘white’ America – over a century and a half too late,” the ACLU brief argued. “Purity of race is a fiction . . . There is no race – there is only mixture. The ‘white’ race is a product of the imagination.”227Brief of Wayne M. Collins as Amicus Curiae on Behalf of the ACLU at 2-3, Regan , 49 F. Supp. 222 (No. 22178-S) [hereinafter Collins Brief]. Like the Guild brief, the ACLU brief – written, Collins later told a colleague, in “great anger, fury and haste”228Letter from Wayne Collins to A.L. Wirin, supra note 226. – also invoked the specter of Nazism: “What plaintiff’s counsel has done is obvious. He has confused the word ‘white’ with the word ‘Aryan’ as understood in modern Germany under Nazi rule.”229Collins Brief, supra note 227, at 2. Although not as focused on the American war effort as the Guild brief, it alluded to the wartime implications of the case: “Thousands of these native born American citizens of alien parentage now serve in our military and naval forces in defense of our traditional rights and liberties. Those who instituted this action have chosen a strange time in which to launch an assault on cherished constitutional rights.”230 Id. at 3-4.

On July 2, 1942, Judge St. Sure dismissed the case in a brief order in which he cited Wong Kim Ark , Morrison v. California , and Perkins v. Elg ,231307 U.S. 325 (1939). a 1939 decision in which the Supreme Court reaffirmed Wong Kim Ark in a case concerning a woman born in the United States but raised in Sweden by her Swedish parents. “This case is exceptional,” St. Sure remarked in the decision, “because the sole question it presents to this court is one which has been definitely decided by the United State Supreme Court.”232 Regan , 49 F. Supp. at 223. Because the question was a matter of settled law, he ruled, it was “unnecessary to discuss the arguments of counsel.”233 Id.

E. The Appeal

Webb sought review of Judge St. Sure’s decision,234Notice of Appeal, Regan , 49 F. Supp. 222 (No. 22178-S). and as the case headed for the Ninth Circuit in the fall of 1942, it attracted broader attention. In December 1942, attorney A.L. Wirin wrote to Collins, asking to have his name added to the ACLU’s brief to the Court of Appeals.235Letter from A.L. Wirin to Wayne Collins, (Dec. 3, 1942) (on file with U.C. Berkeley, Bancroft Library, Wayne M. Collins Papers). Wirin, a Jewish immigrant whose family had fled pogroms in Russia, had previously worked as the ACLU’s first full-time staff attorney and was known for his work defending free speech and worker’s rights.236 See A.L. Wirin, First Counsel to Civil Liberties Union , N.Y. Times , Feb. 5, 1978, at 28; Greg Robinson & Brian Niiya, A.L. Wirin , Densho Encycl. (June 27, 2025, at 15:52 ET), https://encyclopedia.densho.org/A.L.%20Wirin [https://web.archive.org/web/2025102720 1644/https://encyclopedia.densho.org/A.L.&20Wirin]. In 1942, he became involved in legal challenges to internment and became counsel to the Japanese American Citizens League (JACL).237Robinson & Niiya, supra note 236. He took on a central role in litigating Regan v. King at the Ninth Circuit. In addition to joining the ACLU brief, he was also on an amicus brief submitted by the San Francisco and Los Angeles chapters of the National Lawyers Guild.238 See Brief of Amici Curiae in Support of Appellee at 2, Regan v. King, 134 F.2d 413 (9th Cir. 1943) (No. 10299) [hereinafter ACLU Brief] (on file with Nat’l Archives, Records of the U.S. Courts of Appeals, Record Group 276, Appeals Case Files and Briefs (1891-1998)); Brief on Behalf of S.F. & L.A. Chapters of Nat’l Law. Guild as Amici Curiae at 13, Regan , 134 F.2d 413 (No. 10299). More significantly, he brought the JACL into the case.

While Regan v. King was pending at the Ninth Circuit, Wirin attended a JACL national meeting in Salt Lake City, where he briefed participants about the birthright citizenship litigation as well as about the various cases challenging curfews and removal.239Robinson & Niiya, supra note 236. The JACL had, controversially, opted to collaborate with the program of forced removal and incarceration and did not play a role in litigating the cases challenging those policies, but it did decide to get involved in Regan v. King .240For a detailed account of the way that the JACL positioned itself with regard to Regan v. King and other contemporaneous litigation, see Robinson with Wu, supra note 11, at 26-30. As historian Greg Robinson and legal scholar Frank Wu have recounted, two attorneys who were in the JACL leadership, Saburo Kido and Walter Tsukamoto, took an interest in the case, but their ability to participate in drafting a brief was limited, since both were incarcerated at the time.241 Id. at 29. With Wirin’s assistance, they recruited Hugh Macbeth to author a brief on behalf of the JACL.242 Id. Macbeth, a Black civil rights attorney born in Charleston, South Carolina, and educated at Harvard Law School, ran a law firm in Los Angeles with his brother and was the founder of an antiracist advocacy group called United Races of America.243 See Robinson , After Camp , supra note 11, at 172-75. Macbeth founded the organization in 1937. The following year, Governor Frank Merriam appointed Macbeth to be executive secretary of the newly established California Race Relations Commission. Id. He had close ties to the Japanese community in Los Angeles and was among the first attorneys to defend the rights of Issei who were arrested in the wake of Pearl Harbor.244 Id. at 175-80. Macbeth, in turn, recruited Thomas L. Griffith, president of the Southern California branch of the NAACP, to work with him on the brief.245 Id.

Together, these five attorneys – Wirin, Kido, Tsukamoto, Macbeth, and Griffith – submitted a brief on behalf of the JACL that emphasized the broad implications of the case.246Brief for Japanese American Citizens League, Amicus Curiae, Regan v. King, 134 F.2d 413 (9th Cir. 1943) (No. 10299) [hereinafter JACL Brief] (on file with Nat’l Archives, Records of the U.S. Courts of Appeals, Record Group 276, Appeals Case Files and Briefs (1891-1998)). The brief also acknowledged anthropologist Morris Edward Opler for his input on ethnological and historical material. Id. at 76. Their brief argued that, while the framers of the Fourteenth Amendment had primarily been motivated to protect the rights of African Americans, the amendment’s protection was much wider in scope:

Today [those being targeted] are American-Chinese, American-Filipinos, American-Koreans, and Americans of Japanese ancestry. Tomorrow it may be another group. The true relation of the Thirteenth, Fourteenth, and Fifteenth Amendments of the Constitution to the Negroes is that they are a shield protecting human rights on which is emblazoned: “You shall not do again to others as you did it unto these.”247 Id. at 26-27.

The brief repeatedly emphasized the broader implications of the assault that Japanese Americans were experiencing:

You cannot attack the citizenship of those of Japanese ancestry without debasing citizenship as such; and without cheapening the birthright of those of Negro ancestry and White ancestry as well. The Japanese American Citizens League is speaking in this brief, far more than may appear on the surface, not merely for its members whose citizenship is jeopardized by the case at bar, but for an America composed of many peoples united by common ideals—ideals which ugly prejudices and ungrounded hysteria must not be allowed to destroy.248 Id. at 10.

In a section entitled “Interests of Negroes and This Case,” the brief drew connections between Black citizenship and Asian American citizenship. It took aim at a statement in Webb’s brief to the Ninth Circuit in Regan v. King that sought to assure the court that “[t]he status of the Negro is in no way involved in this case.”249 Id. at 43. Seeking to confine the scope of the Citizenship Clause to its immediate post-Civil War context was a standard element of efforts to attack Asian American citizenship, dating back to the government’s briefs in Wong Kim Ark .250Erman & Perl-Rosenthal, supra note 22, at 654-55. This strategy was evident in the language of the constitutional amendments that anti-Asian legislators introduced in the 1920s, which were carefully constructed to draw a line between Asian American citizenship and Black citizenship.251As noted above, restrictionists often distinguished between Black citizenship and Asian American citizenship implicitly, by tethering birthright citizenship to the naturalization statute. Phelan’s proposed amendment, however, did so explicitly, by seeking to restrict birthright citizenship to those whose “parents are white persons, Africans, American Indians, or their descendants.” S.J. Res. 144, 66th Cong., 59 Cong. Rec. 1815 (1920). The JACL brief expressed skepticism about Webb’s assurance, noting:

The very fact that the appellant found it necessary to make this reference attests to the deep uneasiness with which the Negro is watching actions of this kind. The Negro recognizes this assault as a move against that little corner of security possessed by any American minority group of color. He realizes that, except for the absence of war hysteria or other externalized emotionalism directed against him at the moment, he stands in precisely the same position as those of Japanese ancestry.252JACL Brief, supra note 246, at 44. Pointing out Webb’s many references in his brief to whiteness as

foundational to the Constitution, the brief stated that “the Negro knows that this is but a skirmish in a campaign that will overwhelm and dispossess him if it reaches its ultimate goal.”253 Id . at 45. It noted that the goal of overturning Wong Kim Ark had the support of Representative Rankin, one of the most outspoken segregationists in Congress.254 Id. at 46. It also quoted a CJIC document in which the organization had once described the granting of citizenship to African Americans after the Civil War as a “grave mistake.”255 Id. at 47. The CJIC document in question appears as an exhibit to CJIC member Robert Fouke’s testimony at the Tolan Committee hearing on Feb. 21, 1942. National Defense Migration: Hearings Before the House of Representatives Select Comm. Investigating Nat’l Defense Migration , H.R. Res. 113, 77th Cong., Part 29, 10965, 11084-87 (1942) (Exhibit E to Testimony of Robert H. Fouke). It is identified as a report prepared by the CJIC “at the request of the Dies Committee, House of Representatives, on Japanese problems and propaganda.” Id. at 11084. Regan v. King , it argued, was the first step in the CJIC’s “white America” program.256JACL Brief, supra note 246, at 47. The next step, it asserted,

will be to propose a constitutional amendment to “rectify” the “grave mistake” of “the granting of citizenship to the Negroes after the Civil War” and to surrender the final victory to Hitlerism, no matter how the tide of actual battle has gone.257 Id.

The brief emphasized the high stakes of the case for many Americans, imploring the court to take note that, “in spite of the appellant’s exploitation of war-time hysteria and current racial prejudices against those of Japanese ancestry, this action is in reality aimed at persons of many diverse ethnic backgrounds.”258 Id. at 42.

In keeping with Dold’s approach at the oral argument before Judge St. Sure, the City of San Francisco submitted a bare-bones brief that did not include any legal argument. Less than two pages long, it consisted mostly of a quote from Webb’s own brief, in which Webb conceded that what he was asking for was in conflict with the Wong Kim Ark holding.259Brief for Appellee at 1, Regan v. King, 134 F.2d 413 (9th Cir. 1943) (No. 10299) (on file with Nat’l Archives, Records of the U.S. Courts of Appeals, Record Group 276, Appeals Case Files and Briefs (1891-1998)). Dold also apparently planned a similarly minimalist strategy for his oral argument before the Court of Appeals. Two days before the hearing, on the same day that the JACL brief was filed, Wirin sent a telegram to the court informing the court that he had spoken with Dold, who had advised Wirin that “his oral argument will take five minutes,” and that he had no objection to the court allocating the rest of the time to Wirin.260Telegram from A.L. Wirin to 9th Cir. Ct. of Appeals (Feb. 17, 1943) (on file with Nat’l Archives, Records of the U.S. Courts of Appeals, Record Group 276, Appeals Case Files and Briefs (1891-1998)).

Webb seemed to understand the dynamics at play: the public interest lawyers who had submitted amicus briefs were the opposing counsel he cared about, not Dold. Webb did not bother filing a reply to the City’s brief, but did file a lengthy reply to the briefs submitted by the ACLU and the Guild.261Appellant’s Reply to the Briefs of the Civil Liberties Union and National Lawyers Guild, Regan , 134 F.2d 413 (No. 10299) [hereinafter Appellant’s Reply Brief]. (He was apparently not yet aware of the JACL brief, which was filed shortly before the oral argument.) In his reply brief, Webb repeatedly denied that racial animus had anything to do with the suit, claiming that, “[r]ace superiority is not involved” and that “[w]hether the white race is inferior or superior does not affect the question.”262 Id. at 37. He also responded to arguments raised by the ACLU that had not been raised before the district court, including the argument that the citizenship of Japanese Americans was guaranteed not only by the Fourteenth Amendment but also by the Nationality Act of 1940.263 Id. at 32-34; ACLU Brief, supra note 238, at 24. The other argument raised by the ACLU was that the court lacked jurisdiction, because the case did not raise a federal question, since the plaintiff had not suffered any deprivation of his voting rights. ACLU Brief, supra note 238, at 18-19; Appellant’s Reply Brief, supra note 261, at 2-22.

Although the court had granted Wirin’s request to participate in the oral argument,264A.L. Wirin, U.S. Court Upholds Citizenship Rights of Japanese Americans , Pac. Citizen , Feb. 25, 1943, at 5. Wirin never got the opportunity to do so. Webb spent thirty minutes making his argument before the Court of Appeals, which was sitting en banc.265 Id. When Dold rose to present his arguments on behalf of the City, Chief Judge Curtis Wilbur told him not to bother, and took the extraordinary action of announcing the court’s decision from the bench, without even hearing the opposing argument: the decision of the District Court would be sustained.266 Regan , 134 F.2d 413 (per curiam) (affirming dismissal). For accounts of the oral argument, see Wirin, supra note 264; Appeals Court Hears Argument on Jap Issue , Chico Enter. , Feb. 19, 1943, at 3; Court Upholds Voting Rights of Japs Born in U.S. , Chi. Trib. , Feb. 21, 1943, at 13; Irons , supra note 141, at 176-77; Robinson with Wu, supra note 11, at 34. In a per curiam decision, the court cited the Fourteenth Amendment, Wong Kim Ark , and “a long line of decisions” in affirming the judgment of dismissal.267 Regan , 134 F.2d at 413. On May 17, 1943, a little over a year after the complaint was filed, the Supreme Court denied certiorari.268Regan v. King, 319 U.S. 753 (1943).

F. The Aftermath

The immediate impetus for litigating the scope of the Citizenship Clause in 1942 was the substantial doubt that existed within the Roosevelt administration about the constitutionality of incarcerating U.S. citizens of Japanese descent; Webb was seeking to restrict birthright citizenship so that it did not get in the way of internment. Webb lost on the question of the interpretation of the Citizenship Clause, but in other ways he prevailed: birthright citizenship turned out not to be much of an obstacle after all. At the very same time that Regan v. King was being decided, Nisei citizenship was being gutted of its substance in a series of cases upholding actions by the government that singled out Japanese Americans on the sole basis of ethnicity.269 See supra notes 183-85 and accompanying text. Japanese Americans were simultaneously affirmed as citizens on the level of formal status but denied the basic rights of citizenship. They were rendered, in the words of historian Mae Ngai, “alien citizens.”270Mae M. Ngai, Birthright Citizenship and the Alien Citizen , 75 Fordham L. Rev. 2521, 2521 (2007).

In many ways, the 1940s represented a moment of vindication for groups that had been involved in anti-Japanese advocacy for decades: Japanese Americans were deprived of the basic rights of citizenship, and many ultimately lost the formal status of citizenship as well.271 See Frost , supra note 186, at 126-134. It was also, however, the beginning of the end of the movement that the CJIC embodied. Organized labor had traditionally been the mainstay of support for anti-Asian activism, including earlier attempts to restrict birthright citizenship, but even as Regan v. King was being litigated, that was changing. When delegates from 1,300 union locals gathered in Long Beach in September 1942 for the annual convention of the California State Federation of Labor, they overwhelmingly rejected a proposed resolution that would have expressed support for a constitutional amendment barring Japanese Americans from birthright citizenship.272 Cal. State Fed’n of Lab. , Officers’ Reports and Proceedings of the Forty-Third Annual Convention of the California State Federation of Labor 211 (1942). A heated discussion on the floor revealed that the frameworks being put forward by civil rights activists and lawyers reflected broader shifts that were underway; the debate included comments that the proposed resolution was “inhuman, vicious and undemocratic” and “played into the hands of axis propagandists.”273 Attack on Japs Voted Down , Santa Maria Times , Sep. 23, 1942, at 2; Labor is Told U.S. Requires 15 Million Workers , Sacramento Bee , Sep. 24, 1942, at 27; AFL Rejects Plan to Bar American Born Japs from Citizenship , Daily News (L.A.), Sep. 24, 1942, at 37. For perspectives on race and the U.S. labor movement at midcentury, see Marlene Kim, Organizing Asians Americans into Labor Unions , in The State of Asian America : In 1946, when the CJIC drafted a ballot measure to enshrine the Alien Land Law in the state constitution, it lost by a large margin – a sharp contrast to the support that the Japanese exclusion movement had formerly enjoyed in California.274The 1946 measure, Proposition 15, was defeated 59% to 41%. See California Begins Making Amends to Its Japanese , ST. LOUIS POST-DISPATCH, Mar. 2, 1952, at 6A [hereinafter California Begins]; see also KURASHIGE, supra note 102, at 194-202 (discussing the defeat of the ballot measure and other indications of the decline of the exclusionist movement in the postwar period). In contrast, the same set of actors, operating then as the Japanese Exclusion League, had secured a landslide victory in 1920 for a ballot measure aimed at strengthening the Alien Land Law. See infra note 289.

Soon after the 1946 ballot measure, Webb died at the age of eighty-three. Over the next few years, courts began to strike down statutes that discriminated against Asian Americans under the rubric of “ineligibility to citizenship.”275 See, e.g. , Fujii v. State, 242 P.2d 617, 630 (Cal. 1952) (striking down the California Alien Land Law); Namba v. McCourt, 204 P.2d 569, 577 (Or. 1949) (striking down the Oregon Alien Land Law); Takahashi v. Fish & Game Comm’n, 334 U.S. 410 (1948) (striking down a California statute that prohibited the issuance of commercial fishing licenses to immigrants who were ineligible for citizenship); Oyama v. California, 332 U.S. 633 (1948) (holding that a provision of the California Alien Land Law was a violation of the Fourteenth Amendment, as applied to a U.S. citizen with Japanese immigrant parents). In 1952, Congress eliminated the racial bar to naturalization.276Immigration and Nationality Act of 1952, 8 U.S.C. § 1422 (“The right of a person to become a naturalized citizen of the United States shall not be denied or abridged because of race or sex or because such person is married”). A newspaper article that year described the CJIC as having “lost the support of veterans’ and labor groups” and having “disintegrated to a mere paper organization.”277 California Begins , supra note 274, at 6A.

Part III: What Can We Learn from Regan v. King ?

On January 20, 2025, President Donald Trump issued an executive order purporting to upend the long-settled boundaries of American birthright citizenship. Executive Order 14160, entitled “Protecting the Meaning and Value of American Citizenship,” declares that the Fourteenth Amendment’s guarantee of citizenship to all those “born . . . in the United States, and subject to the jurisdiction thereof” extends only to those who, at the time of their birth, have either 1) a father who is a U.S. citizen or lawful permanent resident, or 2) a mother who is neither “unlawfully present in the United States” nor in “lawful but temporary” status.278The relevant language in Executive Order 14160 is as follows: This attempt to make birthright citizenship contingent on a parent’s immigration status directly conflicts with the longstanding interpretation of the Citizenship Clause by federal courts, Congress, and the executive branch.279For examples of how courts have applied the Citizenship Clause, see Doe v. Trump, 766 F. Supp. 3d 266, 280-82 (D. Mass. 2025) (discussing cases applying the Citizenship Clause). For a discussion of how Congress and the executive branch have interpreted the Citizenship Clause, see Law Scholars’ Brief, supra note 67. In defending the legality of the order against multiple legal challenges, the Department of Justice has asked courts to adopt a novel reading of the Citizenship Clause that would narrow the holding of Wong Kim Ark beyond recognition, limiting its application to children whose parents fit within the parameters of the executive order . 280 See, e.g. , Brief for Appellants at 10, Washington. v. Trump, 145 F.4th 1013 (9th Cir. 2025) (No. 25-807) (arguing that United States v. Wong Kim Ark recognized birthright citizenship only for “children of those with a ‘permanent domicil[e] and residence in the United States’”); see Marty Lederman & John Mikhail, Taking Stock of the Birthright Citizenship Cases, Part III: DOJ’s Arguments Regarding Domicile and Unauthorized Immigrants , Just Sec. (Sep. 8, 2025), https://www.justsecurity.org/120152/birthright-citizenshipdomicile/ [https://perma.cc/C886-W4VV] (critiquing the DOJ’s domicile argument). Several district courts and two courts of appeals have rejected the government’s arguments.281Doe v. Trump, 157 F.4th 36, 58 (1st Cir. 2025) (“[P]laintiffs are likely to succeed on the merits of their claims three times over—first, in showing that the children that the EO describes are entitled to birthright citizenship under [8 U.S.C.] § 1401(a) even if Wong Kim Ark must be read as the Government urges us to read it; second, in showing that those children are entitled to birthright citizenship under that federal statutory provision because Wong Kim Ark may not be so read; and third, in showing that, for the very same reason, those children are entitled to birthright citizenship under the Citizenship Clause itself.”); Washington , 145 F.4th at 1035 (“The plain text and ordinary meaning of the Fourteenth Amendment, controlling precedent interpreting the Citizenship Clause, drafting history, and most post-ratification public understanding weigh in favor of Plaintiffs’ interpretation of the Citizenship Clause.”); N.H. Indon. Cmty. Support v. Trump, 765 F. Supp. 3d 102, 109 (D.N.H. 2025) (“As to plaintiffs’ constitutional claim, the Executive Order contradicts the text of the Fourteenth Amendment and the century-old untouched precedent that interprets it.”); Barbara v. Trump, 790 F. Supp. 3d 80 (D.N.H. 2025) (recognizing a class action and extending the preliminary injunction granted in N.H. Indon. Cmty. Support v. Trump to cover all members of the class), cert. granted before judgment , No. 25-365, 2025 WL On December 5, 2025, the Supreme Court granted certiorari in one of these cases, Barbara v. Trump , a class action suit filed in the District of New Hampshire.282 Barbara , 790 F. Supp. 3d 80.

The litigation has prompted a flood of new commentary on the meaning and history of the Citizenship Clause,283For recent commentary arguing that EO 14160 is unconstitutional, see, for example, Ablavsky & Berger, supra note 35; Evan D.

Almost all of this work addresses the common-law roots of birthright citizenship, the drafting of the Fourteenth Amendment, and the nineteenth-century case law interpreting the Citizenship Clause.285For commentary that explores a different angle, see Kristin A. Collins, Gerald Neuman & Rachel E. Rosenbloom, Another Reason Trump’s Birthright Citizenship Order is Unlawful , Just Sec.

Regan v. King offers an entirely new way to understand the current litigation.

Given the unvarnished racism of Webb’s legal arguments, it might be tempting to view Regan v. King as merely a shameful artifact of an earlier era, with little contemporary relevance.286While such language has not been evident in the Trump administration’s litigation on birthright citizenship, expressions of white nationalism have been a frequent element of President Trump’s rhetoric. See, e.g. , Julie Hirschfeld Davis, Sheryl Gay Stolberg & Thomas Kaplan, Trump Alarms Lawmakers with Disparaging Words for Haiti and Africa , N.Y. Times (Jan. 11, 2018), https://www.nytimes.com/2018/01/11/us/politics/trump-shitholecountries.html [https://perma.cc/EE8V-9ERV] (reporting on President Trump’s reference to “shithole countries”). On the place of white nationalist ideology in Trump’s immigration p olicies, see Jayashri Srikantiah & Shirin Sinnar, White Nationalism as Immigration Policy , 71 Yet, we should not be so quick to dismiss its significance. Webb was not a fringe figure. He served as California’s attorney general for nine terms – a total of thirty-seven years.287 See History of the Office of the Attorney General , State of Cal. Dep’t of Just. : Off. of the Att’y Gen. , https://oag.ca.gov/history [https://perma.cc/A8C6-A5X2] (last visited Oct. 17, 2025). He won re-election again and again while persistently attacking the rights of both Japanese immigrants and their U.S.-born children.288For examples of Webb’s involvement in anti-Asian advocacy while in office, see supra Part II.A. His agenda enjoyed broad support among white Californians while he was in office,289One measure of that support is the success of a measure that was on the ballot in California in November 1920. It aimed to prevent land from being purchased in the name of the U.S.-born children of Japanese immigrants, by barring immigrants ineligible for citizenship from serving as guardians for the purpose of such purchases. It was approved by 74% of voters. California Proposition 1, Alien Property Initiative (1920) , Ballotpedia , https://ballotpedia.org/ California_Proposition_1,_Alien_Property_Initiative_(1920) [https://perma.cc/HL6S-PUSB] (last visited Oct. 17, 2025). The provision was later struck down by the California Supreme Court. In re Estate of Yano, 188 Cal. 645, 656 (1922). and he brought the lawsuit in coordination with organizations with substantial memberships. In 1942, in the midst of wartime anti-Japanese hysteria, a majority of Americans believed that Japanese Americans should be “sent back” to Japan.290 See Frost , supra note 186, at 127 (citing Louise Merrick Van Patten, Public Opinion on Japanese Americans , 14 Far E. Surv. 207, 207-08 (1945)). The idea of overturning Wong Kim Ark appealed to figures across regional and political divides, a coalition reminiscent of the one behind the litigation that led to Wong Kim Ark .291Erman & Perl-Rosenthal, supra note 22, at 618-19 (describing the “overlapping white-superiority projects” that brought together opponents of birthright citizenship across sectional and party divides).

Webb chose to employ the language of white nationalism, but it would have been easy for him to make a more sanitized argument. The case law that he cited contained a blueprint for such an argument: the ostensible race-neutrality of restrictions based on “ineligibility to citizenship” was a core element of the defense of discriminatory state laws such as the alien land laws, and enabled such laws to survive numerous legal challenges during this period.292 See, e.g. , Terrace v. Thompson, 263 U.S. 197 (1923) (“Appellants’ contention that the state act discriminates arbitrarily against Nakatsuka and other ineligible aliens because of their race and color is without foundation. All persons of whatever color or race who have not declared their intention in good faith to become citizens are prohibited from so owning agricultural lands.”). The Supreme Court also upheld provisions of alien land laws in Porterfield v. Webb, 263 U.S. 225 (1923); Webb v. O’Brien, 263 U.S. 313 (1923); and Frick v. Webb, 263 U.S. 326 (1923). But see Oyama v. California, 332 U.S. 633, 644 (1948) (striking down provisions of the Alien Land Law as applied to the U.S.-born children of A sian immigrants); Takahashi v. Fish & Game Comm’n, 334 U.S. 410, 422 (1948) The Supreme Court’s decision in Korematsu 293In Korematsu , the Supreme Court declined to conclude that the forced relocation of Japanese Americans was based on racial discrimination: Korematsu was not excluded from the Military Area because of hostility to him or his race. He was excluded because we are at war with the Japanese Empire, because the properly constituted military authorities feared an invasion of our West Coast and felt constrained to take proper security measures, because they decided that the military urgency of the situation demanded that all citizens of Japanese ancestry be segregated from the West Coast temporarily, and finally, because Congress, reposing its confidence in this time of war in our military leaders—as inevitably it must—determined that they should have the power to do just this. Korematsu v. United States, 323 U.S. 214, 223 (1944). In 2018, in Trump v. Hawaii , the Supreme Court took “the opportunity to make express what is already obvious: Korematsu was gravely wrong the day it was decided, has been overruled in the court of history, and – to be clear – ‘has no place in law under the Constitution.’” Trump v. Hawaii, 585 U.S. 667, 710 (2018) (citation omitted). stands as a grim reminder that judges accustomed to viewing discrimination against those “ineligible to citizenship” as uncontroversial found it relatively easy, in the midst of war against Japan, to countenance restrictions on the children of such immigrants.

Regan v. King deserves attention as a bridge between the late nineteenth-century conflicts over birthright citizenship and the ones we are witnessing today. Like Wong Kim Ark itself, and like the present litigation, Regan v. King was an attempt to narrow a previously established interpretation of the Citizenship Clause. Looking at these challenges together reveals that each attempt to persuade the courts to restrict birthright citizenship has produced its own theory about the meaning of the first sentence of the Fourteenth Amendment. In Wong Kim Ark , and in the legal scholarship that led up to it, restrictionists argued that the Citizenship Clause recognized as birthright citizens only the children of U.S. citizens.294More specifically, the government urged adoption of the doctrine that a child born in wedlock followed the citizenship of the father, and a child born out of wedlock followed the citizenship of the mother. See Brief for the U.S. at 10, United States v. Wong Kim Ark, 169 U.S. 649 (1898) (No. 449); see also Wong Kim Ark , 169 U.S. at 708 (1898) (Fuller, J., dissenting) (“The place of birth produces no change in the rule that children follow the c ondition of their fathers . . .”) (citation omitted). In Regan v. King , restrictionists argued that the Citizenship Clause recognized as birthright citizens only children whose parents were either citizens or racially eligible to become citizens. In the current litigation, the government seeks to persuade the courts that the Citizenship Clause recognizes as birthright citizens only children born to at least one parent who is a citizen or possesses a designated immigration status. The government’s chief argument is that children who do not have a parent who fits this description “lack the reciprocal relationship of allegiance and protection that would bring them within the political jurisdiction of the United States.”295Brief for Appellants at 1, Washington. v. Trump, 145 F.4th 1013 (9th Cir. 2025) (No. 25-807). For scholarship that argues for restrictions on birthright citizenship based on theories of consent, allegiance, and domicile, see, for example, Kurt T. Lash, Prima Facie Citizenship: Birth, Allegiance and the Fourteenth Amendment’s Citizenship Clause , 101 Notre Dame L. Rev. (forthcoming 2026); Ilan Wurman, Jurisdiction and Citizenship (July 17, 2025) (unpublished article), https://ssrn.com/abstract=5216249 [https://dx.doi.org/10.2139/ssrn. 5216249]; John C. Eastman, The Significance of “Domicile” in Wong Kim Ark, 22 Chap. L. Rev. 301 (2019). The arguments in this scholarship have been sharply contested by a broad spectrum of scholars. See supra notes 283-284. This argument is premised on a notion that individuals can be said to have (or to lack) something called “primary allegiance” to the United States, a novel term that no court has ever employed in relation to the Citizenship Clause.296Brief for Appellants, supra note 280, at 13. On the government’s dubious reference to “primary allegiance,” see John Mikhail, Birthright Citizenship and DOJ’s Misuse of History in Its Appellate Briefs , Just Sec. (Apr. 18, 2025), https://www.justsecurity.org/110212/birthrightcitizenship-doj-misuse-history/ [https://perma.cc/Q4NE-X5D7] (“The [government’s] brief cites no legal authority for these claims about primary allegiance. Instead, it seems to have made them up out of whole cloth for the purposes of this litigation.”).

The shift in restrictionist arguments between Wong Kim Ark and Regan v. King can be understood as strategic rather than substantive. Webb shared the same goal as the attorneys who sought to limit the scope of birthright citizenship in the 1890s, and merely came up with a different legal theory (grounded in U.S. statutory law rather than international law) to get there. That innovation enabled him to propose a reading of the Citizenship Clause that would have stripped Asian Americans of citizenship while leaving the children of European immigrants unscathed.

In contrast, the shift that has taken place between Regan v. King and the present reveals a fundamental realignment in the effort to restrict birthright citizenship, from one that targeted Asian Americans and relied on arguments about parental ineligibility to naturalize to one that is a) ostensibly race-neutral; b) heavily characterized, in public discourse, by tropes of undocumented Latin American (in particular, Mexican) women giving birth on U.S. soil;297On race and the contemporary restrictionist movement, see Leo R. Chavez , Anchor Babies and the Challenge of Birthright Citizenship (2017); Sandra L. Rierson, From Dred Scott to Anchor Babies: White Supremacy and the Contemporary Assault on Birthright Citizenship , 38 Geo. Immigr. L.J. 1, 30-69 (2023); Robin Jacobson, Characterizing Consent: Race, Citizenship, and the New Restrictionists , 59 Pol. Rsch. Q. 645 (2006). and c) centered on arguments about parental lack of authorized immigration status.298The current attempt to restrict birthright citizenship seeks to exclude not only the children of undocumented parents but also the children of parents who are present in the United States on temporary visas. See supra note 278 and accompanying text. This framing has characterized restrictionist efforts for decades. See, e.g ., Peter H. Schuck & Rogers M. Smith , Citizenship Without Consent: Illegal Aliens in the American Polity 5 (1985) (proposing “a reinterpretation of the Fourteenth Amendment’s Citizenship Clause to make birthright citizenship for the children of illegal and temporary visitor aliens a matter of congressional choice rather than of constitutional prescription.”) In practice, however, calls to restrict birthright citizenship in recent decades have focused primarily on the question of the This realignment, which can be fully understood only in the context of the sweeping changes that have taken place within immigration law since the mid-twentieth century, highlights the degree to which restrictionist arguments, past and present, have relied on the statutory frameworks of their respective eras.

In Regan v. King , Webb sought to tether birthright citizenship to the lines drawn by the naturalization statute, the Asian exclusion laws, and the alien land laws.299 See supra Part II.D. By the 1960s, the entire statutory framework on which his argument had relied was gone; the Asian exclusion laws and the racial bar to naturalization had been repealed, and the alien land laws were no longer in effect.300The Chinese Exclusion Act was repealed in 1943. See Chinese Exclusion Repeal Act of 1943, Pub. L. No. 78-199, § 2, 57 Stat. 600. The passage of the Immigration and Nationality Act in 1952 eliminated the racial bar on naturalization. Immigration and Nationality Act, Pub. L. No. 82-414, § 311, 66 Stat. 163, 239 (1952); see also Gabriel J. Chin, Segregation’s Last Stronghold: Race Discrimination and the Constitutional Law of Immigration , 46 UCLA L. Rev. 1, 13-14 (1998) (discussing piecemeal reforms prior to 1952 that made “races indigenous to the Western Hemisphere,” Chinese immigrants, and Indian and Filipino immigrants eligible for naturalization). The passage of the McCarren-Walter Act formally eliminated the bar on immigration from Asia, but Asian immigrants remained subject to extremely small quotas until 1965. Id. at 13-15. The Supreme Court has never overturned Terrace v. Thompson, the 1923 case rejecting a challenge to the constitutionality of the Washington Alien Land Law, or any of the other cases from the 1920s in which the Court upheld the constitutionality of alien land law provisions. See supra note 292; Shen v. Comm’r, 158 F.4th 1227, 1253-54 (11th Cir. 2025) (referring to the Terrace decision as “moth-eaten” but noting that it has not been overturned); Leo Yu, Reviving Exclusion , 12 Tex. A&M L. Rev. 1683 (2025) (analyzing recently enacted laws in twelve states targeting land ownership by Chinese nationals and describing Terrace and the other cases from the 1920s as “zombie cases” that “no longer possess the full force of good law, but . . . remain on the books with presumed validity.”). However, laws that barred land ownership to those who were ineligible for citizenship became obsolete after the racial bar on naturalization was repealed in 1952. By that point, state supreme courts in both Oregon and California had struck down the respective alien land laws of those states as violations of the Fourteenth Amendment. See Fujii v. State, 242 P.2d 617, 630 (1952); Namba v. McCourt, 204 P.2d 569, 582-83 (1949); see also Yu, supra , at 1698-700 (discussing cases decided in the 1970s in which the Supreme Court cast doubt on the continuing validity of the Terrace line of cases); Gabriel J. Chin & Anna Ratner, The End of California’s Anti-Asian Alien Land Law: A Case Study in Reparations and Transitional Justice , 29 Asian Am. L.J. 17 (2022) (discussing t he repeal of the California Alien Land Law and the payment of reparations). In the decades that followed, a different legal framework took shape, one which has turned out to be just as essential to contemporary efforts to restrict birthright citizenship as those laws had been to Webb’s arguments. This framework has fundamentally altered the legal, social, and political meaning of being present without authorization in the United States, drawing a sharp line between undocumented parents and U.S. citizen children in contemporary mixed-status families.301For a more detailed discussion of these changes, see Rosenbloom, supra note 11, at 323-29.

As historian Mae Ngai has written, “illegal alienage is not a natural or fixed condition but the product of positive law; it is contingent and at times it is unstable.”302 Ngai , supra note 188, at 6. Ngai’s work points to the 1920s as the decade in which the figure of the “illegal alien” emerged as a new legal and political subject, one that soon came to be racialized as Mexican.303 Id. at 71 (tracing a series of changes in the 1920s that led to “[t]he undocumented Mexican laborer who crossed the border to work in the burgeoning industry of commercial agriculture emerg[ing] as the prototypical illegal alien”). As the work of Ngai and others has shown, however, the line that divided undocumented immigrants and U.S. citizens within mixed-status families remained permeable in the early twentieth century. For some mixed-status families, unauthorized status turned out to be merely a technical problem that could be fixed: in the wake of new visa requirements and numerical limits on immigration imposed in 1924 by the Johnson-Reed Act,304Immigration (Johnson-Reed) Act of 1924 , Pub. L. 68-139, 43 Stat. 153. The concept of unauthorized status can be traced back to state restrictions on immigration before the Civil War. See Hidetaka Hirota , Expelling the Poor: Atlantic Seaboard States & the 19 th-Century Origins of American Immigration Policy 2 (2019); Kevin Kenny , The Problem of Immigration in a Slaveholding Republic : Policing Mobility in the 19 th-Century United States 1 (2023); Gerald L. Neuman, The Lost Century of American Immigration Law (1776-1875) , 93 Colum. L. Rev. 1833, 1841-83 (1993). However, a new understanding of the “illegal alien” emerged in the wake of the 1924 Act and the criminalization of unauthorized entry in 1929. See Ngai , supra note 188, at 56-74. policymakers crafted a variety of administrative processes to enable the growing number of European and Canadian unauthorized immigrants to transition to lawful permanent residence (in some cases, based on a showing that their deportation would cause hardship to a citizen child).305 Ngai , supra note 188, at 75-76. In the 1930s, immigration officials repeatedly sought statutory authorization to grant relief to unauthorized immigrants based on hardship to family members who were citizens or permanent residents, and they made clear to Congress that hardship to citizen children should be a basis for such relief. See Law Scholars’ Brief, supra note 67, at 14-15. Congress granted that authority in 1940, creating a form of relief known as suspension of deportation. Alien Registration (Smith) Act of 1940. Pub. L. No. 76-670, § 20, 54 Stat. 670, 671-73. Suspension of deportation was later included in the Immigration and Nationality Act of 1952. Immigration and Nationality Act, Pub. L. No. 82-414, § 244, 66 Stat. 163, 214 (1952). Many of the suspension cases that the agency went on to grant involved parents who were accorded lawful status and a path to citizenship on the basis of a showing of hardship to their U.S.-born children, and all of these cases came to Congress for review under the initial statutory scheme. See Law Scholars’ Brief, supra note 67, at 27-29; Ngai , supra note 188, at 84-90; Richard A. Boswell, Crafting an Amnesty with Traditional Tools: Registration and Cancellation , 47 Harv. J. on Legis. 175, 180-95 (2010). Meanwhile, within ethnic Mexican mixed-status families (few of which benefitted from these new forms of relief)306 Ngai , supra note 188, at 86-87. the line between undocumented immigrants and their U.S. citizen family members was often permeable in a very different way: U.S. citizenship provided little protection in the face of the mass expulsions to Mexico that state and federal agencies carried out during economic downturns. These “repatriations” (better understood as banishment, as historian Marla Ramírez argues),307 See Marla A. Ramírez , Banished Citizens: A History of the Mexican American Women who Endured Repatriation (2025) (exploring oral histories of U.S. citizen women subject to repatriation between 1921 and 1944). swept up people of Mexican descent regardless of status; it is estimated that sixty percent of the approximately one million ethnic Mexicans “repatriated” to Mexico in the interwar period were U.S. citizens.308 Id . at 6 (“The immigration raids that spanned the interwar period from 1921 to 1944, combined with denied relief and employment opportunities, led to the expulsion of approximately one million Mexicans, a startling 60 percent of whom were US citizens of Mexican descent.”); see Raymond Rodríguez & Francisco E. Balderrama , Decade of Betrayal: Mexican Repatriation in the 1930S 149-51 (1995); Kevin R. Johnson, The Forgotten “Repatriation” of Persons of Mexican Ancestry and Lessons for the “War on Terror” , 26 Pace L. Rev. 1, 1-2 (2005). If citizenship status failed to protect Mexican Americans against expulsion during economic downturns, it was also the case that lack of authorized status often posed little barrier to Mexican immigrants in times when employers needed workers; land borders remained porous, and work authorization was not required for employment.309Congress did not prohibit the employment of unauthorized workers until 1986.

In all of these different ways, the lines between documented and undocumented, citizen and noncitizen, remained blurred.

Between the 1960s and the 1990s, those lines hardened. As the number of Mexican undocumented immigrants in the United States rose – a result of statutory changes in the 1960s that transformed formerly lawful flows of temporary workers from Mexico into new flows of unauthorized migrants310Douglas S. Massey & Karen A. Pren, Unintended Consequences of US Immigration Policy: Explaining the Post-1965 Surge from Latin America , 38 Population & Dev. Rev. 1, 1 (2012). Massey and Pren point to 1968 as a key turning point. That was when numerical restrictions on immigrants from the Western Hemisphere, which were introduced through the Hart-Celler Act in 1965, went into effect. Id. at 3. (Those restrictions, which initially capped Western Hemisphere immigration at 120,000 people annually, were later adjusted to impose a cap of 20,000 on each country). Id. at 1-2. That was also the first year following the wind-down of the Bracero Program, which had provided authorization for temporary workers from Mexico since 1942. Id. at 3. As Massey and Pren explain, between the late 1950s and the late 1970s, “Mexico went from annual access to around 450,000 guestworker visas and a t heoretically unlimited number of resident visas in the United States (in practice averaging around 50,000 per year) to a new situation in which there were no guestworker visas and just migratory flows did not disappear but simply continued without authorization or documents.” Id at 5. Thus, Massey and Pren explain, “illegal migration rose after 1965 not because there terminated and the number of permanent resident visas had been capped, leaving no legal way to accommodate the long-established flows.” Id; see also Kevin R. Johnson, The Beginning of the End: The Immigration Act of 1965 and the Emergence of the Modern U.S.-Mexico Border State , 1965 Act and its aftermath, that “one might claim that, over the last fifty years, the United – the media began portraying Mexican immigrants as a threat to the United States.311 See Leo R. Chavez , The Latino Threat: Constructing Immigrants , Citizens , and the Nation 22 (2008); see also Cecilia Menjívar, The Racialization of “Illegality” , 150 Dædalus , J. Am. Acad. Arts & Sci. 91, 91-94 (2021) (discussing the association of illegality with Mexican and Central American immigrants and noting that “[t]he racialization of illegality is . . . tied to notions of deserving and undeserving, good and bad immigrants.”); César Cuahtémoc García Hernández, Creating Crimmigration , 2013 BYU L. Rev. 1457, 1503-07 (2014) (discussing threat narratives directed at Central American, Haitian, and Cuban migrants in the 1980s and ‘90s). Rising anti-immigrant sentiment and public perception that the border was out of control led to a series of restrictive immigration laws, beginning in the late-1980s: the curtailing of options for regularizing status;312On the narrowing of paths to regularizing status, see Boswell, supra note 305, at 193-95 (2010). the militarization of the U.S.-Mexico border;313 Nevins , supra note 309, at 63, 85; Massey & Pren, supra note 310, at 9-14. the proliferation of federal and state laws that require people to furnish proof of lawful status in an ever-growing list of settings, such as obtaining a job or a driver’s license;314 See generally Huyen Pham, When Immigration Borders Move , 61 Fla. L. Rev. 1115 (2009) (describing the increasing significance of immigration and citizenship status in the interior of the United States). and a cluster of developments, often grouped together under the term “crimmigration,” that have blurred the line between immigration law enforcement and criminal law enforcement.315On the convergence of immigration law and criminal law, see García Hernández, supra note 311; Yolanda Vázquez, Constructing Crimmigration: Latino Subordination in a “Post-Racial” World , 76 Ohio St. L.J. 599, 650 (2015); Juliet Stumpf, The Crimmigration Crisis: Immigrants, Crime, and Sovereign Power , 56 Am. U. L. Rev. 367, 376 (2006). Rather than being understood as a potentially temporary state, being undocumented came to be understood as a type of person, defined by illegality.316Unauthorized presence can be the basis for the initiation of removal proceedings, which the Supreme Court has recognized as a “purely civil” process. See INS v. Lopez- Mendoza, 468 U.S. 1032, 1038 (1984) (“A deportation proceeding is a purely civil action to determine eligibility to remain in this country . . . .”). While entry and reentry without authorization are criminal offenses, see 8 U.S.C. §§ 1325, 1326, unlawful presence, on its Meanwhile, the passage of civil rights legislation,317 See, e.g. , Civil Rights Act of 1964, Pub. L. No. 88-352, 78 Stat. 241. combined with the advent of federally-funded legal services programs and the founding of advocacy groups such as the Mexican American Legal Defense and Education Fund,318 See generally Earl Johnson , JR., Justice and Reform: The Formative Years of the American Legal Services Program (1978) (tracing the history of the legal services movement); Michael A. Olivas , No Undocumented Child Left Behind: Plyler v. Doe and the Education of Undocumented Schoolchildren 10-19 (2012) (discussing the history of the Mexican American Legal Defense and Education Fund). meant that citizenship rights started to mean more. Together, these changes sharpened the line running down the middle of mixed-status families.

It is this contemporary understanding of “illegality” – as a fixed and all-encompassing status – and this contemporary understanding of citizenship – as a meaningful source of rights – that animate the current push for restrictions on birthright citizenship. The first scholars to propose the restrictions on birthright citizenship now embodied in the Executive Order, Peter Schuck and Rogers Smith, argued in 1985 that the “massive increase in illegal migration to the United States,” a development that they characterized as “a new, convulsive violation of consensually based political community,” called for rethinking the boundaries of birthright citizenship.319 Schuck & Smith , supra note 298, at 3, 91. The rise in undocumented immigration was one factor that they cited. The other was the rise of the welfare state. Id. A recent commentary on the current birthright citizenship litigation by legal scholar Richard Epstein shows how profoundly this understanding of illegality continues to shape the way that contemporary restrictionists approach the question of the meaning of the Citizenship Clause. “Why would anyone defend birthright citizenship for the children of illegal entrants in to the United States,” Epstein asks, “when that view obliterates, as a matter of constitutional design, the line between legal and illegal conduct?”320Richard Epstein, The Hopeless Case for Birthright Citizenship: The Fourteenth Amendment Did Not Touch the Status of the Children of Illegal Aliens and Temporary Visitors to the United States (May 14, 2025) (unpublished article), https://papers.ssrn.com/ sol3/papers.cfm?abstract_id=5254575 [https://dx.doi.org/10.2139/ssrn.5254575].

Epstein’s question is intended to be rhetorical, but we can learn something by asking it in earnest, in a slightly different form. Why, we might ask, did Webb show no concern, in 1942, about the fact that the Citizenship Clause, even under his constrained reading, would have accorded citizenship to the children of many (non-Asian) immigrants who lacked authorized status?321Webb’s argument, tying birthright citizenship to ineligibility to naturalize, would, in theory, have reached those whose parents were ineligible to naturalize based on requirements outside the racial prerequisite, such as having to demonstrate lawful entry. See Immigration Act of 1940, Pub. L. No. 76-853, § 329(b), 54 Stat. 1137, 1152 (“No declaration of intention shall be made by any person who arrived in the United States after June 29, 1906, until such person’s lawful entry for permanent residence shall have been established, and a certificate showing the date, place, and manner of arrival in the United States shall have been issued.”). However, none of the statements by Webb or others involved in the litigation expressed any intention to tie birthright citizenship to this criterion. Such families were of no concern to Webb. Nor were they of concern to Representative Rankin, Senator Stewart, Earl Warren, the Chief Justice of the New Mexico Supreme Court, or the various governors and advocacy organizations that expressed support for overturning Wong Kim Ark . Voices that called for restricting birthright citizenship all converged solely on a different set of mixed-status families: those that combined parents racially ineligible to naturalize and children who were birthright citizens.

As Webb’s own words make clear, his selective focus was driven by racial animus. We should not lose sight, however, of the statutory scheme that enabled him to turn that animus into arguments for restricting birthright citizenship. Birthright citizenship held heightened significance within Asian immigrant communities in the United States in the early twentieth century, due to the racial bar on naturalization and the many discriminatory laws that incorporated that bar. Webb and others sought to leverage the contradictions posed by the sharp divide that these laws created between citizen children and Asian immigrant parents. In contrast, the type of mixed-status families targeted by current restrictionists would have presented a very different picture.322It should be noted that the groups behind Regan v. King had a long track record of hostility toward Mexican immigrants. See supra note 105. They did not attack Mexican American birthright citizenship, either in Regan v. King or elsewhere. However, if the CJIC had succeeded in its goal of classifying Mexicans as racially barred from naturalization, Webb’s arguments in Regan v. King would have also impacted the birthright citizenship of the children of Mexican immigrants – a fact that underscores the significant role played by t he naturalization statute. Outside of Asian immigrant communities, the line between undocumented parents and citizen children was far less significant in the 1940s than the line that Webb sought to leverage. Tracing the transition between Regan v. King and the current litigation makes it clear that the preoccupations of policymakers in particular eras have profoundly shaped the paths of arguments to restrict the scope of birthright citizenship. Epstein’s question, like Webb’s argument, can be articulated only against the backdrop of a particular statutory scheme.

The impulse that these challenges embody – to mold birthright citizenship to the lines drawn by contemporary statutory law – is precisely what the Reconstruction Congress sought to prevent when it took the step of enshrining a broad rule of birthright citizenship in the Fourteenth Amendment. Senator Jacob Howard made this aim clear when he proposed that birthright citizenship should be guaranteed in the Fourteenth Amendment even though Congress had just enacted a statute to that effect.323Civil Rights Act of 1866, ch. 31, 14 Stat. 27. “We desire[],” he explained, “to put this question of citizenship and the rights of citizens and freedmen under the civil rights bill beyond the legislative power of [those] who would pull the whole system up by the roots and destroy it, and expose the freedmen again to the oppressions of their old masters.”324 Cong. Globe , 39th Cong., 1st Sess. 2896 (1866). In Wong Kim Ark , the Supreme Court recognized that this motivation led to the inclusion of birthright citizenship in the Fourteenth Amendment, noting that the framers of the amendment “evidently [thought] it unwise, and perhaps unsafe, to leave so important a declaration of rights to depend upon an ordinary act of legislation, which might be repealed by any subsequent congress . . . .”325United States v. Wong Kim Ark, 169 U.S. 649, 675 (1898). The Court also discussed this aspect of the Citizenship Clause in Afroyim v. Rusk , 387 U.S. 253, 262 (1967): [W]hen the Fourteenth Amendment passed the House without containing any definition of citizenship, the sponsors of the Amendment in the Senate insisted on inserting a constitutional definition and grant of citizenship. They expressed fears that the citizenship so recently conferred on Negroes by the Civil Rights Act could be just as easily take[n] away from them by subsequent Congresses, and it was to provide an insuperable obstacle against every governmental effort to strip Negroes of their newly acquired citizenship that the first clause was added to the Fourteenth Amendment.

The current litigation does not, of course, concern an attempt by Congress to restrict birthright citizenship, but rather an action that the framers of the Fourteenth Amendment would likely have found even more alarming: an executive order.326 See Garrett Epps, Interpreting the Fourteenth Amendment: Two Don’ts and Three Dos , 16 Wm. & Mary Bill Rts. J. 433, 456 (2007) (“[The Reconstruction] Congress’s attention was mostly fixated on reclaiming its prerogatives against aggressive overreaching by an accidental President.”); see also Afroyim , 387 U.S. at 263 (noting that the framers of the Fourteenth Amendment “wanted to put citizenship beyond the power of any governmental unit to destroy”). At minimum, however, it raises the same concerns that an attempt by Congress to restrict birthright citizenship would raise.327For a discussion of other concerns that such a change would raise, see Amanda Frost, The Coming Assault on Birthright Citizenship , Atlantic (Jan. 7, 2025), https://www.theatlantic. com/politics/archive/2025/01/birthright-citizenship-trump/681219/ [https://perma.cc/ D P5R-X8GM]. Conclusion The Trump administration is asking courts to rewrite the Citizenship Clause to conform to the contemporary construction of immigrant illegality, which itself is profoundly embedded in statutory changes made in the twentieth century. If courts were to allow shifting rationales such as these to shape the contours of birthright citizenship, they would be defeating one of the central aims of the Fourteenth Amendment.

Looking at the current litigation through the lens of Regan v. King is a reminder that arguments for restricting birthright citizenship are historically contingent, shaped by both the political norms and the statutory frameworks of their respective eras. Recognizing this fact does not, on its own, answer the question facing the Supreme Court about the meaning of the Citizenship Clause. It should, however, cause the Court to approach contemporary arguments for restriction with as much skepticism as the courts had for Webb’s arguments in the 1940s. The outrageousness of Webb’s language should not distract us from the distinct parallels that can be drawn between the arguments that he offered in 1942 and the arguments being advanced in the litigation today. Restrictionists past and present have presented versions of the same basic argument: that the framers of the Fourteenth Amendment could not possibly have meant to guarantee a form of birthright citizenship that would one day appear to conflict so seriously with a contemporary statutory scheme.

That temporal dynamic is exactly what the framers of the Fourteenth Amendment sought to guard against. They could not have foreseen what particular targets would emerge in the decades and centuries that followed their drafting, but they did not have to: their own experience in a divided nation and a divided government taught them that their efforts to overturn Dred Scott might be fragile if guaranteed only by statutory law. That is why they sought to put birthright citizenship out of reach of the legislative process. In 1942, as in 1898, this impulse was vindicated: the Citizenship Clause functioned as the Reconstruction Congress had intended, protecting birthright citizenship against exactly the sort of temporary logic that its framers had anticipated. Even at a time when the courts broadly accepted the racial exclusions in the naturalization statute and the various forms of state-sponsored discrimination that flowed from it, they drew the line at extending those forms of discrimination to U.S.-born children, due to the clear and expansive language of the Citizenship Clause.

The judges who have ruled on the current cases so far have reached the same conclusion, striking down Executive Order 14160 with words as unequivocal as those of the judges who ruled on Webb’s complaint in Regan v. King . Judge John Coughenour of the Federal District Court for the District of Washington, appointed to the bench in 1981 by President Ronald Reagan, issued a stinging rebuke to the government, declaring the executive order “blatantly unconstitutional” and remarking that, in over four decades on the bench, he could not “remember another case where the question presented is as clear as this one is.”328David Gutman, Judge in Seattle Blocks Trump Order on Birthright Citizenship Nationwide , Seattle Times (Jan. 23, 2025, at 12:44 ET), https://www.seattletimes.com/seattlenews/politics/judge-in-seattle-blocks-trump-order-on-birthright-citizenship-nationwide/ [https://perma.cc/LXK7-S5J7]. Judge Deborah Boardman of the Federal District Court for the District of Maryland commented from the bench, “No court in the country has ever endorsed the president’s interpretation. This court will not be the first.”329David Nakamura & Silvia Foster-Frau, Federal Judge in Maryland Blocks Trump’s Birthright Citizenship Order , Wash. Post (Feb. 5, 2025), https://www.washingtonpost.com/ immigration/2025/02/05/birthright-citizenship-injunction-trump-immigration/ [https:// perma.cc/3VS6-4LZE].

One way or another, this particular cycle of restrictionism will soon come to a close, but it may not be the last. As the civil rights lawyers who drafted the JACL amicus brief presciently observed, safeguarding the near-universal rule of birthright citizenship established by the Fourteenth Amendment is an ongoing task. “Today [those being targeted] are American- Chinese, American-Filipinos, American-Koreans, and Americans of Japanese ancestry,” they wrote in 1943. “Tomorrow it may be another group.”330JACL Brief, supra note 246, at 26-27.
