Justice Thomas is inventing a domicile fiction to strip citizenship from millions of children.
Chief Justice Roberts’s opinion for the Court — joined by Justices Barrett, Sotomayor, Kagan, and Jackson — reaffirmed what Wong Kim Ark, 169 U.S. 649 (1898), settled and what the 14th Amendment’s text states: “All persons born in the United States, and subject to the jurisdiction thereof, are citizens.” That language was drafted to overturn the slave-status ruling the Amendment was passed to repudiate, and the Solicitor General conceded at argument that the President’s executive order contradicted the constitutional text. The Chief’s reliance on Wong Kim Ark and the common-law tradition the 14th Amendment incorporated is itself an interpretive choice — the precedential, prudential path that resolved the case without unsettling settled doctrine. The majority chose institutional stability over methodological display. That choice is what makes the rest of the opinion unremarkable, which is the highest praise a constitutional ruling can earn.
The dissents did not make that choice. They chose to display methodology, and what they displayed is the subject of this column. Justice Thomas, joined by Justice Gorsuch, argued that originalism turns on a person’s “domicile” — “the permanent members of the body politic — the people whose roots were in a place.” Justice Alito, dissenting solo, argued that originalism turns on whether a child owes “allegiance solely to this country.” Justice Kavanaugh filed an opinion concurring in the judgment and dissenting in part, agreeing that the President’s order was illegal as a matter of statutory law but reserving the constitutional question for another day.
Three constitutional theories, mutually exclusive. The Wall Street Journal Editorial Board, in its July 1 column, observes that the dissenters “can’t all be correct.” The Board reads the disagreement as evidence that this Supreme Court is not the “lockstep MAGA majority” critics have warned about. The honest reading is the opposite, and it is more devastating to the conservative legal project than the cartoon version the Board is rebutting.
The conservative legal movement has spent four decades promoting originalism as the disciplined methodology that constrains judicial will. The dissents demonstrate that it constrains nothing. Thomas reads the historical record to find domicile. Alito reads the same record to find allegiance. Gorsuch reads Thomas’s reading and immediately notices the implication Thomas declined to draw — that long-term residents have nowhere else to be “domiciled.” Kavanaugh, the most disciplined textualist in the group, reads the controlling statutes and bypasses the constitutional question.
These are not four applications of one method. They are four conclusions, each dressed in the same methodological vocabulary, each citing the same founding-era sources, each reaching results that cannot be reconciled. The scholarship documenting the gap between originalist claims and originalist results — and the methodology’s character as faith rather than method — has just been proven in 194 pages of Supreme Court opinions. The proof was provided by the methodology’s own practitioners, in opinions joined by Justices who have spent their careers telling the public that originalism is the only legitimate way to read the Constitution.
But this textualist sleight of hand collapses under the weight of the very history the dissenters claim to revere. In 1866 legal usage, “jurisdiction” meant the reach of sovereign authority — who was amenable to the law, not the political alienage of a person’s parents. During the debates on the Civil Rights Act of 1866, ch. 31, 14 Stat. 27, which the Amendment was designed to constitutionalize, Senator Lyman Trumbull explicitly defined “subject to the jurisdiction thereof” as meaning “not owing allegiance to anybody else.” The constitutional exception was for sovereign allegiances — diplomats and invading armies. The concept of the “illegal alien” did not exist in 1868; federal immigration regulation did not begin until the Page Act of 1875. The conservative dissent is reading a post-1875 statutory category backward into the Reconstruction Congress, inventing a requirement to solve a political problem the framers never contemplated and the text does not support.
Justice Thomas’s footnote reserves the question of children born to “illegal aliens” who have lived in the United States for years. “I would reserve for another day the question whether the children of illegal aliens can be domiciled here.” This is not a hypothetical category. The footnote identifies the precise population whose citizenship the next administration — of either party — will test in the next case. Justice Gorsuch’s separate writing gestures at the answer Thomas declined to give: “If those parents are not domiciled here, then where are they domiciled?” Gorsuch’s separate writing reads as an argument that long-term residents meet Thomas’s domicile test — which would put Gorsuch closer to the majority’s holding than to Thomas’s dissent, even though Gorsuch signed that dissent.
Kavanaugh’s concurrence in the judgment is the most analytically interesting of the four. He reads the Immigration and Nationality Act of 1952 and its 1940 predecessor as codifying the Wong Kim Ark reading. The President’s order is illegal as a matter of statutory law, he concludes, regardless of how the broader constitutional question is resolved. The argument is narrower than the majority’s but reaches the same result on the order before the Court. Kavanaugh’s statutory ground is also the writing that most clearly protects the majority’s holding from a future administration willing to test the reserved questions.
That protection matters. The executive order the Court rejected was sweeping. A future administration, briefed by lawyers who read the dissents carefully, could return with an order tailored to the domicile theory — limited to children born to mothers who arrived within the past year, or to children born to parents in active removal proceedings. Thomas reserved the question. The next test case will not allow the question to stay reserved.
Justice Thomas’s dissent asks the reader to believe that the Reconstruction Congress, which explicitly constitutionalized birthright citizenship to overturn Dred Scott v. Sandford, 60 U.S. 393 (1857), and enfranchise the children of formerly enslaved people, secretly intended to authorize a hereditary caste of stateless people born on American soil. The majority closes that door. The conservative dissent’s attempt to pick the lock with a fabricated key does not make the dissenters serious originalists. It makes them, as they have always been when the text gets in the way, revisionists.
The four dissents do not show independent minds at work. They show that originalism, as practiced by its most credentialed adherents, produces whatever result the practitioner prefers. That finding — methodological confession rather than methodological vindication — is the load-bearing fact the Editorial Board declined to name.
