What Supreme Court Precedent? It's been my understanding for weeks now that the USSC has NEVER ruled on the definition of Natural Born Citizen.
Although the consular report of birth abroad shares some features with a passport, it is historically associated with naturalization, not foreign affairs. In order to establish a "uniform Rule of Naturalization," Congress must be able to identify the categories of persons who are eligible for naturalization, along with the rules for that process. Congress thus has always regulated the "acquisition of citizenship by being born abroad of American parents . . . in the exercise of the power conferred by the Constitution to establish a uniform rule of naturalization." United States v. Wong Kim Ark, 169 U. S. 649, 688 (1898) ; see also Miller v. Albright, 523 U. S. 420, 456 (1998) (Scalia, J., concurring in judgment) (recognizing that "Congress has the power to set the requirements for acquisition of citizenship by persons not born within the territory of the United States"). It has determined that children born abroad to U. S. parents, subject to some exceptions, are natural-born citizens who do not need to go through the naturalization process. 8 U. S. C. S:S: 1401(c), (d), (g).On their face, the bolded passages are conflicting on the question of a 1401(g) person being naturalized.
Cruz's memo also cites McCain precedent and S.Res. 511, old-man Romney, and a CRS publication.
Finally, it cites the applicable naturalization law as evidence that Cruz was not naturalized.
