New Opinions: June 30th | 3 Blockbusters End the Term

OVERVIEW

Three opinions released June 30th, 2026 — the final day of the October 2025 Term — spanning birthright citizenship, transgender athletes in school sports, and political party campaign spending.

Two decisions split 6-3 along identical lines — the same conservative majority, anchored by Kavanaugh — in West Virginia v. B.P.J. (Title IX and equal protection) and NRSC v. FEC (First Amendment). A third split 5-4 in Trump v. Barbara, with Chief Justice Roberts and Justice Barrett crossing coalitions to strike down the President's birthright citizenship order alongside the Court's three liberal justices.

Justice Kavanaugh authored two majorities and a pivotal concurrence-in-judgment-and-dissent-in-part in the third — the day's most prolific author. Justice Gorsuch filed three separate writings across two cases — two dissents in Barbara (one joining Thomas, one solo) plus a concurrence in B.P.J. Justice Thomas wrote a dissent in Barbara and a concurrence in B.P.J. The liberal bloc — Sotomayor, Kagan, Jackson — voted together in all three cases, splitting only in B.P.J. where Sotomayor and Jackson each filed separate partial dissents.

Trump v. Barbara spans 194 pages — 30 more than another blockbuster this Term, the Trump Tariff Cases.

Trump v. Barbara | Case No. 25-365 | Argued: 04/01/2026 | Decided: 06/30/2026

Overview: President Trump's executive order strips birthright citizenship from children of unlawfully or temporarily present parents, triggering a constitutional fight over the Fourteenth Amendment's Citizenship Clause.

Question Presented: Whether the Citizenship Clause guarantees citizenship to children born here to unlawfully or temporarily present parents.

Posture: District Court enjoined the order; Supreme Court granted cert before judgment.

Holding: Children born in the United States to parents unlawfully or temporarily present still fall "subject to the jurisdiction" of the United States and thus qualify as citizens at birth under the Citizenship Clause.

Voting Breakdown: 5-4. Chief Justice Roberts wrote the majority opinion joined by Sotomayor, Kagan, Barrett, and Jackson. Justice Jackson filed a concurring opinion, joined by Sotomayor as to the introduction and Part I. Justice Kavanaugh filed an opinion concurring in the judgment and dissenting in part. Justice Thomas filed a dissenting opinion joined by Gorsuch. Justice Alito filed a dissenting opinion. Justice Gorsuch filed a separate dissenting opinion. Affirmed.

Majority Reasoning: (1) English common law granted citizenship by birth regardless of parents' momentary presence; (2) The Fourteenth Amendment and Wong Kim Ark (1898) codify that rule, rejecting Dred Scott; (3) Historical record shows scant evidence Congress intended a domicile requirement.
