Quick Summary
The US Supreme Court ruled 6-3 on Tuesday, June 30, that President Donald Trump’s executive order seeking to end birthright citizenship is unconstitutional, delivering one of the most consequential rebukes of his second term. In Trump v. Barbara, Chief Justice John Roberts wrote for the majority that children born on US soil to parents who are undocumented or present temporarily are citizens at birth under the 14th Amendment. Hours after the ruling, the Justice Department announced it would prioritize criminal prosecutions targeting so-called “birth tourism” schemes.
What Happened
The Supreme Court’s decision in Trump v. Barbara struck down Executive Order 14160, which Trump signed on the first day of his second term in January 2025 in an attempt to deny automatic citizenship to children born in the United States to parents who were either in the country illegally or on temporary visas. Every lower court that reviewed the order found it unconstitutional before it ever took effect.
Chief Justice Roberts, joined by five other justices, grounded the ruling in the text and history of the 14th Amendment’s Citizenship Clause, which grants citizenship to anyone “born … in the United States, and subject to the jurisdiction thereof.” Roberts pointed to the Supreme Court’s 1898 decision in United States v. Wong Kim Ark, which affirmed birthright citizenship for a man born in San Francisco to Chinese immigrant parents, as a precedent that has stood for well over a century.
Justice Brett Kavanaugh agreed the executive order should fall but reasoned it conflicted with federal statute rather than the Constitution itself, leaving open a narrow path for Congress to legislate exceptions in the future. Justices Clarence Thomas and Neil Gorsuch dissented, arguing the majority’s reading of the amendment’s history was flawed.
Background
Birthright citizenship, rooted in the legal principle of jus soli, has been a settled feature of American law since the 14th Amendment was ratified in 1868 in the aftermath of the Civil War. It was designed in large part to guarantee citizenship to formerly enslaved people and their children, overriding the Supreme Court’s notorious 1857 Dred Scott decision.
Trump has long argued that immigrants without legal status or on temporary visas are not “subject to the jurisdiction” of the United States, and that the current system amounts to what he has called a “scam” exploited by foreign nationals. The case moved through the courts for more than a year, with a federal judge in New Hampshire blocking the order in 2025 and certifying a nationwide class of affected children before the administration asked the Supreme Court to intervene directly.
Why It Matters
The ruling affects an estimated 255,000 children born each year in the United States to noncitizen parents, preserving their automatic citizenship and the rights that come with it. It also represents a significant test of the limits of executive power in Trump’s second term, with the conservative-majority Court siding against the administration on one of its signature immigration policies.
The decision does not end the political fight. Trump is now pushing Congress to pursue legislation narrowing birthright citizenship, an effort Kavanaugh’s concurring opinion suggested could theoretically survive constitutional scrutiny, though such a bill would likely face steep opposition and its own legal challenges.
Expert Analysis
Legal impact: Roberts secured his majority with only one of the Court’s other conservatives, Justice Amy Coney Barrett, joining his constitutional reasoning, while Kavanaugh reached the same result on narrower statutory grounds.
Political impact: The decision is a rare defeat for Trump’s immigration agenda at the Supreme Court after a term in which the administration won other major cases, including on nationwide injunctions.
Enforcement impact: The Justice Department’s same-day announcement prioritizing prosecutions of “birth tourism” schemes signals the administration intends to pursue immigration restriction through criminal enforcement of existing fraud and visa laws rather than through the citizenship clause itself.
Statistics & Context
The ruling came down 6-3, with Chief Justice Roberts writing the majority opinion. Justice Kavanaugh concurred in the judgment on different grounds, and Justices Thomas and Gorsuch dissented. An estimated 255,000 children born annually in the US to noncitizen parents were at stake in the case.
What’s Next
Attention now shifts to Congress, where Trump is expected to press Republican lawmakers to pursue legislation restricting birthright citizenship. The Justice Department’s new focus on birth tourism prosecutions is also likely to generate its own legal challenges in the months ahead.
FAQ
What did the Supreme Court rule in Trump v. Barbara? The Court ruled 6-3 that Trump’s executive order attempting to end birthright citizenship is unconstitutional.
Does this ruling affect people who are already US citizens? No. Citizenship rules remain unchanged from before the order was signed.
Can Congress still try to change birthright citizenship? Justice Kavanaugh’s concurring opinion suggested Congress could theoretically pass legislation addressing the statutory question, though most legal experts say any such law would still face significant constitutional challenges.
What is “birth tourism,” and why is the Justice Department targeting it? Birth tourism refers to foreign nationals traveling to the US specifically to give birth so their child gains automatic citizenship. The DOJ said it will prioritize prosecuting such schemes under existing visa fraud, identity theft, and money laundering laws.
