The United States Supreme Court has delivered a significant legal defeat to former President Donald Trump, ruling that birthright citizenship is enshrined in the Constitution. In a 6-3 decision delivered this afternoon, the court rejected the administration’s argument that the 14th Amendment’s citizenship clause did not apply to children born in the United States to undocumented immigrants.
Chief Justice John Roberts, writing for the majority, stated that the amendment’s text is unambiguous: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States.” The ruling reaffirms long-standing precedent dating back to the 1898 case United States v. Wong Kim Ark, which established that children born on American soil are automatically citizens regardless of their parents’ immigration status.
The Trump administration had argued that the phrase “subject to the jurisdiction thereof” excluded children of undocumented immigrants, whom they claimed owed allegiance to another nation. The court dismissed this interpretation, noting that the United States exercises jurisdiction over all individuals within its borders, irrespective of legal status.
Justice Clarence Thomas, joined by Justices Samuel Alito and Neil Gorsuch, filed a dissenting opinion arguing that the 14th Amendment was never intended to grant citizenship to the children of those unlawfully present. However, the dissent failed to sway the majority.
The decision has immediate and far-reaching implications for an estimated 4.5 million children born in the United States to undocumented parents, many of whom are now adults. Advocacy groups have hailed the ruling as a victory for civil rights, while conservative critics have condemned it as judicial overreach.
President Joe Biden welcomed the decision, stating in a brief press conference that “birthright citizenship is a cornerstone of American democracy and a reflection of our nation’s commitment to fairness and opportunity.” The White House had filed an amicus brief in support of the existing interpretation.
Former President Trump, who had made ending birthright citizenship a central plank of his immigration policy, responded via his social media platform, calling the decision “a tragic mistake” and vowing to pursue a constitutional amendment to overturn it. Legal experts consider such an amendment unlikely given the supermajority required for ratification.
The ruling arrives amid a broader political debate over immigration ahead of the 2026 midterm elections. Analysts suggest the decision could energise both pro-immigrant advocates and anti-immigration activists, potentially reshaping the electoral landscape.
The Supreme Court’s decision is final unless a future court reverses it, which remains a possibility only if the ideological composition of the court shifts significantly. For now, birthright citizenship remains the law of the land.
