The alarming split in the Supreme Court’s birthright citizenship ruling

Supreme Court Upholds Birthright Citizenship, Rules 6-3 Against Trump Executive Order

The Supreme Court on July 1, 2026, ruled 6-3 that President Donald Trump’s executive order limiting birthright citizenship violated federal law. The decision affirmed a lower court injunction blocking the order from taking effect.

In Trump v. Barbara, the Court addressed whether the January 2025 order, which directed federal agencies not to recognize citizenship for children born in the United States after February 20, 2025, whose parents lacked lawful permanent residence, complied with the Fourteenth Amendment and statute. Three families had challenged the order in the U.S. District Court for the District of New Hampshire, which certified a class and enjoined enforcement pending litigation.

Chief Justice John Roberts wrote the majority opinion, joined by Justices Amy Coney Barrett, Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson. The opinion held that the Citizenship Clause of the Fourteenth Amendment guarantees citizenship to persons born in the United States and subject to its jurisdiction, without additional domicile or status requirements not stated in the text.

Roberts wrote: “Citizenship, then and now, was the right to have rights — to freely participate in our political community. The Framers of the 14th Amendment extended that promise to ‘every free-born person in this land.’ We keep that promise today.” The opinion rejected arguments that the clause incorporated a domicile requirement or excluded children of parents present temporarily or without authorization.

Justice Brett Kavanaugh filed an opinion concurring in the judgment. He agreed that the executive order was unlawful but rested his conclusion on 8 U.S.C. § 1401 rather than a direct constitutional holding. Kavanaugh stated that the statute, which codifies the principles from United States v. Wong Kim Ark (1898), sets forth a closed list of exceptions that the order exceeded. He wrote that treating the Wong Kim Ark exceptions as permanently fixed was inconsistent with the Court’s interpretive approach in other areas and left open the possibility that Congress could address additional categories through legislation.

The three dissenting justices—Clarence Thomas, Neil Gorsuch, and Samuel Alito—would have upheld the order or concluded that the Citizenship Clause does not extend to children of parents lacking permanent legal status. Thomas’s principal dissent, joined by Gorsuch, argued that the original understanding of the clause was limited to persons whose allegiance was solely to the United States and did not automatically include children of temporary visitors. Alito’s separate dissent contended that children who acquire citizenship in another country through parental nationality are not subject exclusively to U.S. jurisdiction and that current policy encourages birth tourism.

The majority opinion addressed and rejected the domicile and allegiance arguments advanced in the dissents, stating that the text of the Citizenship Clause contains none of the limiting terms appearing in the executive order. Roberts noted that Congress has considered but never enacted legislation altering statutory birthright citizenship rules in the past thirty years.

Legal observers differed on the significance of the separate writings. Aarti Kohli, executive director of the Asian Legal Caucus, said the outcome should have been unanimous because the order attempted to alter constitutional text by executive action. Betsy Fisher, advocacy counsel at United Stateless, stated that a domicile-based interpretation would create practical difficulties in determining status and could leave some children without citizenship in any country.

Other analysts noted that Kavanaugh’s statutory concurrence preserved the result while signaling that future legislative changes to 8 U.S.C. § 1401 remain possible without a constitutional amendment. The decision leaves in place the nationwide injunction issued by the district court and ends the 2025-26 term’s review of the order.

The case originated from challenges filed in spring 2025 after the executive order was issued on the first day of the new administration. Oral argument occurred on April 1, 2026. The Court’s opinion and separate writings together span more than 100 pages and set forth competing interpretations of the Citizenship Clause’s text, history, and subsequent case law.
