Trump v. Barbara · ¶63

How much? The Government offers a smorgasbord of formulations: “primary allegiance,” “sufficient allegiance,” “full allegiance,” “requisite allegiance.” Brief for Petitioners 12, 14, 15, 17, 19, 21, 23, 29, 32, 42. (The principal dissent, for its part, seems to have settled on “primary allegiance.” Post, at 17, 22, 25, 29, 58.) What all these formulations supposedly share is that they turn on domicile—the place of one’s permanent home. At some point before the ratification of the Fourteenth Amendment, the argument goes, it became “deeply rooted” in this country that “[d]omicile is the key concept that creates allegiance.” Tr. of Oral Arg. 26.
