The Supreme Court ruled 5-4 that Trump's executive order ending birthright citizenship violates the 14th Amendment, but a Kavanaugh concurrence opens a legislative path.
The Supreme Court on June 30, 2026, struck down President Trump's executive order purporting to end birthright citizenship for children born in the United States to parents present unlawfully or on temporary visas [1]. Chief Justice John Roberts authored the majority opinion, holding that such children satisfy the 14th Amendment's Citizenship Clause and are entitled to citizenship by birth on U.S. soil [1]. The decision was 5-4 [1].
The case, *Trump v. Barbara*, arose from constitutional challenges to a Day One executive order Trump signed at the start of his second term [1]. Federal courts had blocked the order at the district level, and the litigation advanced through the appellate system before the Supreme Court took it up [1]. The Court resolved the core constitutional question that lower courts had debated for more than a year, directly addressing whether executive action could redefine the citizenship guarantee embedded in the 14th Amendment [2].
Justice Brett Kavanaugh concurred in the judgment but declined to join Roberts's constitutional holding, writing separately on narrower statutory grounds [1]. That distinction carries practical weight: Kavanaugh's concurrence suggests that Congress, rather than the executive branch alone, may have a viable path to revisit birthright citizenship through legislation, without running into the same constitutional barrier that doomed the executive order [1] [2]. Trump moved quickly to highlight that potential legislative avenue following the ruling [1].
The dissent, joined by Justices Clarence Thomas, Neil Gorsuch, and Samuel Alito, would have upheld the executive order [1]. Their position, now the minority view, reflected a longstanding originalist argument that the phrase "subject to the jurisdiction thereof" in the 14th Amendment excludes children of parents who lack permanent legal status [2]. The majority rejected that reading [1].
The ruling is the most consequential immigration decision of the term and settles, at least as a matter of current constitutional interpretation, a question that has shadowed immigration policy debates for decades [2]. It does not foreclose legislative action, and Kavanaugh's concurrence gives the administration and Congress a doctrinal foothold to pursue statutory alternatives [1] [2]. Congressional leaders have not announced a timetable for any such legislation, and the administration has not yet indicated whether it will press for a bill in the current session.
