A divided Supreme Court on Tuesday upheld a broad conception of birthright citizenship, rejecting President Donald Trump’s executive order declaring that children born in the United States to undocumented immigrants or temporary foreign residents are not American citizens.
The justices relied on a long-settled understanding of the 14th Amendment, adopted after the Civil War, and more recent federal laws in ruling that anyone born in the country, with very limited exceptions, is a citizen.
“Citizenship, then and now, was the right to have rights—to freely participate in our political community. The Framers of the Fourteenth Amendment extended that promise to ‘every free-born person in this land,’” Chief Justice John Roberts wrote for the court, citing congressional debate over the amendment, “We keep that promise today.”
Three conservative justices would have allowed the restrictions to take effect.
“The Court today takes the extraordinary step of holding facially unconstitutional the President’s Order excluding from citizenship the children of foreign temporary visitors and illegal aliens,” Justice Clarence Thomas wrote in a 91-page dissent, more than three times as long as Roberts’ opinion. “In doing so, the Court adds to the sad history of the Fourteenth Amendment, which was designed and understood to secure equal rights for the freed blacks but has instead been repurposed for political projects that the Reconstruction Congress did not support.”
The Republican president’s restrictions had been blocked by several lower courts and had not taken effect anywhere in the U.S.
During arguments in April, both conservative and liberal justices questioned the order’s legality in a momentous case that was magnified by Trump’s unprecedented attendance in the courtroom.
The case framed another test of Trump’s assertions of executive power that defy long-standing precedent for a court with a conservative majority and a robust view of presidential power that has largely ruled in his favor. In the notable exceptions when the court has not, Trump has responded with starkly personal criticisms of the justices.
The justices ruled on Trump’s appeal of a lower-court ruling from New Hampshire that struck down the citizenship restrictions.
The birthright citizenship order, which Trump signed on the first day of his second term, is part of his administration’s broad immigration crackdown.
Birthright citizenship was the first Trump immigration-related policy to reach the court for a final ruling. The justices previously struck down global tariffs Trump had imposed under an emergency powers law that had never been used that way.
Trump reacted furiously to the late February tariffs decision, saying he was ashamed of the justices who ruled against him and calling them unpatriotic.
He also seemed to recognize the court was likely to rule against him on birthright citizenship, too, using his Truth Social platform to criticize “dumb judges and justices” and wealthy pregnant women from China and elsewhere who come to the U.S. to give birth so their newborns will have American citizenship.
Trump’s order would have upended widely held views that the 14th Amendment confers citizenship on everyone born in the U.S., excluding only the children of foreign diplomats and those born to a foreign occupying force.
The amendment was intended to ensure that Black people, including former slaves, had citizenship, though the Citizenship Clause is written more broadly. “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside,” it reads.
In a series of decisions, lower courts have struck down Trump’s executive order as illegal. The decisions have invoked the high court’s 1898 ruling in Wong Kim Ark, which held that the U.S.-born child of Chinese nationals was a citizen.
Roberts, joined by Justice Amy Coney Barrett and the three liberal justices, said the amendment’s language, the historical context and the 1898 case make clear that children born to undocumented immigrants or parents temporarily in the U.S. “are citizens at birth.”
But there was only a bare majority of five justices on the constitutional question.
Justice Brett Kavanaugh sided with the majority, but only because of a federal law that makes those children citizens.
Kavanaugh joined the dissenters in finding that Trump’s order does not violate the Constitution. His view would enable a future Congress to change the law to restrict birthright citizenship.
The Trump administration had argued that the common view of citizenship is wrong, asserting that children of noncitizens are not “subject to the jurisdiction” of the United States and therefore are not entitled to citizenship.
More than one-quarter of a million babies born in the U.S. each year would have been affected by the executive order, according to research by the Migration Policy Institute and Pennsylvania State University’s Population Research Institute.
While Trump has largely focused on illegal immigration in his rhetoric and actions, the birthright citizenship restrictions also would have applied to people who are legally in the United States, including students and applicants for green cards, or permanent resident status.
