Supreme Court Strikes Down Trump Order Ending Birthright Citizenship in Landmark Ruling
The Supreme Court struck down President Donald Trump’s executive order attempting to end birthright citizenship Tuesday, with a 6-3 ruling affirming that virtually all children born on American soil are automatically citizens regardless of their parents’ immigration status. The decision in Trump v. Barbara, written by Chief Justice John Roberts, represents the most significant ruling on the 14th Amendment in a generation and delivers a clear constitutional rebuke to the White House.
Majority Affirms Constitutional Guarantee
Roberts, joined by Justice Amy Coney Barrett alongside the court’s three liberal justices, held that the 14th Amendment’s Citizenship Clause grants birthright citizenship to children born in the United States even when their parents are in the country illegally or on temporary visas. The majority opinion drew directly on the court’s 1898 precedent in Wong Kim Ark, which first established that principle in federal law.
“Children born in the United States to parents unlawfully or temporarily present are ‘subject to the jurisdiction’ of the United States and are citizens at birth under the Fourteenth Amendment’s Citizenship Clause,” Roberts wrote. “Under the Constitution, they are citizens at birth.”
The justices were unanimous in rejecting the administration’s core argument: that the Citizenship Clause required children to owe “primary allegiance” to the United States at birth, which the government tied to the concept of “domicile.” Roberts called that interpretation “dramatically revisionist” and said there was “scant evidence” to support it.
Dissents and Political Fallout
Justice Samuel Alito wrote one of three dissenting opinions, calling the ruling “one of the most important decisions in the history of the Court” and “a serious mistake.” He argued the 14th Amendment was designed to secure rights for formerly enslaved Black Americans, not to extend citizenship broadly to the children of non-citizens. Justices Clarence Thomas and Neil Gorsuch also dissented, with Gorsuch raising questions about whether the ruling’s logic would apply to parents with no fixed domicile anywhere.
Justice Brett Kavanaugh agreed with the outcome but not the reasoning, arguing Trump’s order violated a federal statute from 1940 rather than the Constitution itself. He noted Congress could theoretically amend that law or pass new legislation to restrict birthright citizenship, though he acknowledged it had not yet done so.
Trump issued the executive order on January 20, 2025, his first day back in the White House for a second term. The order was slated to take effect 30 days later but never went into effect, as federal judges across the country issued injunctions blocking its enforcement while challenges worked their way through the courts.
Trump Vows Congressional Response
Trump responded to the ruling on his Truth Social platform, calling the decision “too bad for our Country” but arguing that Congress could achieve the same result through legislation without a constitutional amendment. “Congress should start TODAY to work on ending expensive and unfair to our Country, Birthright Citizenship,” he wrote. “They will have my Complete and Total Support!”
The American Civil Liberties Union, which argued the case before the court, hailed the outcome. “This victory belongs to all of us and to the American people,” said Cecillia Wang, the ACLU’s national legal director, in an interview. “The president of the United States was trying to undo this foundational right that all Americans have relied on for 150 years.”
If Trump’s order had been upheld, an estimated 60,000 to 100,000 children born in the United States each year to undocumented immigrants or temporary visitors would have been denied citizenship documents, according to immigration law scholars.
What Happens Next
The ruling is final and immediately restores the long-standing interpretation of birthright citizenship under the 14th Amendment. The Trump administration must resume processing citizenship applications for all children born on American soil who were previously denied under the blocked executive order. Immigration attorneys expect a surge of retroactive applications in the coming weeks. Congressional efforts to restrict birthright citizenship through legislation are expected to begin immediately, though such a bill would require 60 votes in the Senate to advance under current procedural rules.
