The Supreme Court on Tuesday blocked President Donald Trump’s executive order aimed at ending birthright citizenship for children born in the United States to undocumented immigrants and temporary foreign residents. In a 6-3 ruling, the justices reaffirmed that the 14th Amendment of the U.S. Constitution guarantees citizenship to nearly all individuals born on American soil, a principle upheld for over a century.

Chief Justice John Roberts authored the majority opinion, joined by conservative Justices Amy Coney Barrett and Brett Kavanaugh, as well as liberal Justices Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson. Writing for the majority, Roberts stated that the Constitution’s language is clear: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” He emphasized that citizenship has historically been understood as “the right to have rights” and that the framers of the 14th Amendment extended this promise to “every free-born person in this land.” Roberts rejected the Trump administration’s attempt to reinterpret the amendment by limiting automatic citizenship based on parental immigration status, calling this a “dramatically revisionist view” unsupported by constitutional text or history.

Justice Kavanaugh offered a separate opinion agreeing that the executive order violated current federal law but not the Constitution. He argued that changes to birthright citizenship, particularly concerning children of foreign nationals, would require congressional action rather than an executive order.

President Trump, who closely followed the case and attended part of the oral arguments earlier this year, criticized the ruling on social media. He described the decision as “too bad for our Country” but urged Congress to pass legislation to end birthright citizenship, asserting a constitutional amendment was unnecessary. However, legal experts and commentators noted that overturning birthright citizenship by legislation would face significant obstacles, including bipartisan opposition in the Senate and the high threshold for constitutional amendments.

The ruling ends a legal battle that has spanned several years, marking a setback for Trump’s broader immigration agenda. Critics of the executive order argued that it would have jeopardized the rights of thousands of children and complicated immigration status for families, potentially leaving some children stateless. Defenders of Trump’s policy viewed birthright citizenship as an incentive for illegal immigration and birth tourism.

The decision also drew historical context, referencing the 1898 Supreme Court case United States v. Wong Kim Ark, which established that children born in the United States to immigrant parents are citizens by birth. The court’s majority rejected arguments rooted in 19th-century anti-immigrant and racist scholarship that sought to limit citizenship rights.

The Trump administration sought to challenge the long-standing interpretation through unilateral executive action, but the Supreme Court reaffirmed that such a substantive change to citizenship law requires constitutional or legislative processes, not simply an executive decree. The ruling underscores the resilience of birthright citizenship as a constitutional principle and reflects deep divisions within the court and the country on immigration issues.
