During the 2016 Presidential election a number of constitutional scholars debated Ted Cruz’s eligibility to be President. This was not the first time in recent American history that the meaning of the Constitution’s “natural born citizen” clause was a live issue in American law.1 The answer to this legal question depends on the particular theory of constitutional interpretation one favors.2 There has been a good deal of speculation on this issue by scholars of different methodological commitments. Much of the debate focuses on the meaning of the 1790 Naturalization Act, which raises deeper questions about the evolving debate over the legitimacy of originalism as a constitutional theory.3 Rather than approach the meaning of eighteenth-century constitutional and legal texts in a genuinely historical fashion, originalists have adopted a method plagued by anachronism, which invariably leads to distortion.4

The problems with originalism are evident if one takes a close look at the way one of the key texts in the “natural born citizen debate,” the Naturalization Act of 1790, has been interpreted by originalists. In this Act, the First Congress declared “the children of citizens of the United States, that may be born beyond Sea, or out of the limits of the United States, shall be considered as natural born Citizens: Provided, that the right of citizenship shall not descend to persons whose fathers have never been resident in the United States.”5 Historians and originalists interested in discerning this text’s legal meaning in 1790 approach the problem from radically different methodologies.

For most historians, the first step in any such inquiry is to establish the range of possible beliefs this provision might have had in the founding era.6 The entire process of historical interpretation is guided by a holistic approach to meaning. As historian Jonathan Gienapp has recently argued, “The meaning of individual linguistic components—words, phrases, or utterances—can only be understood in terms of their relations within the conceptual vocabulary of which they are a part.”7 Finally, genuine historical inquiry embraces a form of thick contextualism. Context is never a simple given. Historical actors, and the historians who interpret their words, must actively construct the relevant linguistic and ideological contexts for interpreting texts from among the multiplicity of potential contexts available at any historical moment.8

By contrast, originalists approach meaning in an atomistic fashion, looking at the meaning of words as isolated linguistic facts. The originalist conception of context is also exceedingly thin.9 Originalist Lawrence Solum compares constitutional texts to messages in a bottle. In this metaphor context functions like a bucket filled with additional facts—pour the contents of the bottle into the bucket and out comes meaning.10

Neal Katyal and Paul Clement, two of the nation’s most distinguished lawyers, opt for an originalist approach to interpreting the natural born citizen requirement in an influential essay in the Harvard Law Review Forum.11 Focusing on the 1790 Naturalization Act, they conjure up a reading that is almost impossible to imagine being accepted by most lawyers and judges in the founding era. “The Naturalization Act of 1790[,]” they assert, “expanded the class of citizens at birth to include children born abroad of citizen mothers as long as the father had at least been resident in the United States at some point.”12 Their textualist approach is patently ahistorical. The two lawyers have unconsciously imported modern norms of gender equality into their analysis and produce an interpretation that is utterly implausible.13 According to Katyal and Clement, the 1790 Act rejected earlier English law, which limited the rights of natural born subjects to children of English fathers.14 Katyal and Clement’s anachronistic reading offers no evidence to substantiate such a view.

One of the few founding era texts they do cite, Sir William Blackstone’s Commentaries, actually undercuts their argument, but Katyal and Clement’s originalist approach blinds them to this realization.15 It is impossible to talk about citizenship without recognizing the importance of gender in legal definitions of who was a citizen in 1790. “By marriage,” Blackstone wrote, “the husband and wife are one person in the law; that is, the very being or legal existence of the woman is suspended during the marriage, or at least is incorporated and consolidated into that of the husband, under whose wing, protection, and cover, she performs every thing;”16 Thus, for Katyal and Clement’s reading of the 1790 Act to be correct, it would mean that the First Congress had overturned the doctrine of coverture. Not only is there no evidence to support such a bold claim, but if Katyal and Clement had looked at the relevant case law from the founding era on coverture, especially the case of Martin v. Commonwealth,17 they would have immediately grasped how radical their reading would have been in the founding era.

Among the issues central to Martin was the question of a married woman’s capacity to assert her political independence and choose her own political allegiance.18 Martin demonstrates how far outside of mainstream founding era legal thought such a feminist reading of the 1790 Act would have been.19 The judges of Massachusetts’ highest court dealt extensively with the implications of coverture for woman’s legal identity as a citizen. In their view, a feme covert, the situation of a married woman whose legal identity was subsumed within her husband’s during marriage, could have no separate political identity outside of her husband’s national allegiance.20 To accept Katyal and Clement’s interpretation of the meaning of the text of the 1790 Act would mean that the First Congress overturned the pre-existing English doctrines on naturalization, allegiance, and citizenship, and also dismantled a key aspect of the legal doctrine of coverture. Moreover, it would entail accepting that the First Congress struck a major blow for women’s rights that went unnoticed by any contemporary commentator, including some of the nation’s leading jurists, who addressed the issue a little more than a decade later in Martin.21

Katyal and Clement are not the only originalists to have approached the 1790 Act in an anachronistic fashion. Michael Ramsey, another prominent originalist, makes the 1790 Act a cornerstone of his argument in several blog posts and in a forthcoming article.22 In his view, Congress inherited the virtually limitless power of the English Parliament to redefine the terms of citizenship, including the meaning of the term “natural born citizen.”23 The most obvious problem with such a claim is that it equates Parliament’s power in this area, which was absolute under the English Constitution, with Congressional power under the American Constitution, which was far more limited in its scope.24

A much more historically plausible reading of the 1790 Act would begin with the recognition that most members of the First Congress accepted the Blackstonian understanding of coverture and hence took it as unproblematic that the category of natural born citizen already articulated in English law was based on the status of one’s father alone.25 A residence requirement for fathers would not have been seen as a repudiation of the pre-existing understanding of the paternal roots of citizenship, or a revolutionary step toward gender equality in citizenship, but rather a goal consistent with the widespread fears that aliens might exploit America’s generous terms of acquiring citizenship to foment counter-revolution. This interpretation better accords with the political and ideological context in which these early debates over naturalization occurred; the problem Congress grappled with was how to balance the need for a republican conception of naturalization against the danger of foreign threats to America’s new republican experiment, particularly the danger posed by subversion from radical immigrants.26 Moreover, the doctrine of coverture and the gender norms in place at this time all contradict the feminist reading of the 1790 Act.27 Finally, one must apply eighteenth century rules of statutory construction, not modern textualist norms, if one seeks the historical meaning of this act.28 According to those rules, the meaning of a statute was to be derived from an “understanding of the mischief to be remedied.” Congress was worried that citizens living abroad might pass citizenship on to children without ever residing in the United States. Representative Livermore expressed this concern clearly when he warned “that right might be transmitted from father to son and on to perpetuity.”29 The law sought to accommodate the needs of Americans living overseas without creating a situation where one might be eligible to be President without having any real connection with America apart from a claim based on paternity. To conclude that the First Congress intended to equalize gender claims for citizenship without any clear historical reason for taking up this issue not only violates the rules of construction familiar to most lawyers at the time, it makes little historical sense. It is hard to fathom what logic would have impelled the First Congress to add an additional residency requirement for fathers living abroad, at the same time that they allowed mothers to avoid such a requirement.

Finally, originalism’s focus on how a hypothetical fully informed founding era lawyer would have read the texts is misguided.30 Rather than speculate on what fictive constructed readers might have thought about the law, as many originalists suggest, historical inquiry must look at what actual readers thought. Only after establishing what actual readers thought can one hazard a guess at how to weigh any particular reading in terms of its influence or typicality in the founding era. Originalists talk in the language of empirical history, but upon closer inspection there is little genuinely empirical about their claims about how readers behaved.31 This intellectual sleight of hand is neatly accomplished by assuming a level of consensus in the founding era that few serious historians would accept as an accurate description of founding constitutional culture.32 Using this method one can make any evidence from the founding the foundation for a revisionist argument about public meaning. In practice, moving from what specific readers of historical legal texts believed they meant to the larger question of how common such a reading may have been in the founding era is among the most difficult tasks undertaken by historians and must be approached cautiously.33

One of the most interesting “actual readers” to comment on the meaning of this clause was the distinguished Virginia lawyer and jurist St. George Tucker. Originalists sometimes use Tucker and other early commentators on the Constitution as proxies for establishing the contours of an American legal mind, but Tucker was hardly a neutral voice in the contentious debates of the Constitution’s first decade; he was an ardent Jeffersonian Republican. Understanding Tucker’s ideological position in the debates of the 1790s is necessary to evaluating his interpretation of the natural born citizen clause. Tucker represented one pole of the spectrum of legal thought in this period. On this issue, Jeffersonians, including Tucker, were champions of a more open view of naturalization and immigration policy. Tucker thus offers a useful starting point for constructing the outer limits of what a permissive interpretation of naturalization would have looked like in the 1790s. His examination of this issue occurs in an extensive footnote in his annotated edition of Blackstone’s Commentaries.34

In contrast to modern originalists, Tucker did not believe that the power to create uniform rules of naturalization meant that Congress could alter the scope of the natural born citizen clause.35 After reviewing the 1790 Act, and the Naturalization Act of 1795 that dropped any reference to natural born, Tucker stated unambiguously that “[p]ersons naturalized according to these acts, are entitled to all the rights of natural born citizens” except for certain express limits on their ability to hold federal offices.36 As far as the Presidency was concerned, Tucker was emphatic: “they are forever incapable of being chosen to the office of President of the United States.”37 The dominant view among Jeffersonians, the group most sympathetic to the rights of aliens, thus cuts decisively against the notion that Congress had the power to retroactively redefine the meaning of the natural born citizen clause, at least regarding presidential eligibility.38

Recent originalist accounts of the natural born citizen clause only underscore the theoretical and methodological flaws in this approach to constitutional interpretation. It seems hard to credit the notion that the dominant view in the founding era abandoned the longstanding gender hierarchies and patriarchal assumptions that governed thinking about citizenship in the Anglo-American legal world prior to the enactment of the Naturalization Act of 1790.39
