Supreme Court upholds birthright citizenship 6-3, striking down Trump's executive order

Summary

The Supreme Court ruled 6-3 on June 30 that the 14th Amendment's citizenship clause bestows citizenship on virtually all persons born on US soil, striking down Executive Order 14160, which President Trump signed on January 20, 2025, directing agencies not to recognize citizenship for children born to parents who are neither citizens nor lawful permanent residents. Chief Justice Roberts wrote for a majority that included Justices Sotomayor, Kagan, Barrett, and Jackson, citing United States v. Wong Kim Ark (1898) and quoting: "The Framers of the Fourteenth Amendment extended that promise to every free-born person in this land. We keep that promise today." Kavanaugh filed a separate concurrence on statutory grounds only, without reaching the 14th Amendment question, and explicitly wrote that Congress "could, consistent with the Fourteenth Amendment, amend §1401(a) or otherwise enact new legislation establishing exceptions," a legislative door that Trump immediately tried to walk through. Justices Thomas, Alito, and Gorsuch dissented; Thomas's dissent ran 91 pages arguing the Citizenship Clause applied only to former slaves. The order was never implemented.

Trump responded on Truth Social calling the ruling "too bad" and urging Congress to act through legislation rather than a constitutional amendment, but his own Republican allies split: Heritage Foundation President Kevin Roberts and Sen. Mike Lee called for a constitutional amendment, arguing legislation alone would not hold.

The split

The Roberts majority and liberal justices read Wong Kim Ark as decisive: citizenship for persons born on US soil is a textual and historical fact not subject to executive redefinition. Kavanaugh's concurrence deliberately stayed on statutory ground, preserving the question of whether Congress could act, and is the most legally significant opinion because it signals where the key fifth vote would have landed if legislation replaces the EO. The dissenters, particularly Thomas's lengthy reading, argued the Citizenship Clause's original meaning was narrower than the 127-year-old precedent the majority relied on. Internationally, no foreign government formally responded; Al Jazeera and European outlets covered the ruling but noted the US is unusual among peer democracies in still extending birthright citizenship without restriction.

By the numbers

• 6-3, the vote (Roberts, Sotomayor, Kagan, Barrett, Jackson, plus Kavanaugh concurrence vs. Thomas, Alito, Gorsuch)
• 91, pages in Thomas's dissent
• 1898, year of United States v. Wong Kim Ark, the controlling precedent
• 0, lower courts that had upheld EO 14160 before it reached the Supreme Court
• 52 U.S.C. §1401(a), the statute Kavanaugh cited as the narrow legislative path

Why it matters

The ruling is the term's most significant immigration decision and a direct rebuff to one of Trump's signature second-term priorities. Kavanaugh's concurrence is the most consequential element going forward: by refusing to reach the 14th Amendment on constitutional grounds, he left open the possibility that a future Congressional statute could narrow birthright citizenship in ways a court with his vote might sustain. The Republican split between the legislation camp (Trump) and the amendment camp (Heritage, Lee) will define the political fight ahead of the 2026 midterms.

What to watch

• Whether Senate Republicans introduce legislation to narrow birthright citizenship, and whether Kavanaugh's concurrence provides a roadmap courts will accept
• Thomas's dissent as a template for a future majority if the court's composition changes
• State-level Republican responses and whether any governors attempt to implement non-recognition policies on a different legal theory
• 2026 midterm framing: birthright citizenship is now a live legislative issue rather than a settled constitutional one
