The United States Supreme Court has reaffirmed the constitutional guarantee of birthright citizenship, delivering a significant legal defeat to President Donald Trump’s efforts to end automatic citizenship for children born on American soil to undocumented immigrants and temporary residents. In a closely watched 6-3 ruling, the court held that the Constitution’s 14th Amendment continues to protect citizenship for nearly everyone born in the United States, regardless of their parents’ immigration status.
Chief Justice John Roberts authored the majority opinion, joined by Justices Sonia Sotomayor, Elena Kagan, Ketanji Brown Jackson and conservative Justice Amy Coney Barrett. Justice Brett Kavanaugh agreed with the outcome but wrote separately, arguing that the executive order conflicted with existing federal law rather than directly violating the Constitution. Conservative Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented, maintaining that the Citizenship Clause should not extend to children of undocumented immigrants or temporary visitors.
The ruling strikes down an executive order issued by Trump shortly after returning to office in 2025, which sought to deny automatic citizenship to children born in the United States if their parents lacked legal immigration status or were in the country temporarily. The order had been challenged in several courts before reaching the Supreme Court and never came into force because of nationwide legal injunctions.
In its judgment, the majority traced the historical evolution of American citizenship, noting that the 14th Amendment was adopted after the Civil War to overturn the infamous Dred Scott decision, which had denied citizenship to Black Americans. The court also relied on long-established legal precedent, including the landmark 1898 United States v. Wong Kim Ark ruling, which confirmed that children born on US soil are citizens regardless of their parents’ nationality.
Roberts wrote that citizenship remains a fundamental constitutional guarantee and rejected arguments that birthright citizenship should depend on ancestry or parental allegiance. The majority concluded that Trump’s interpretation lacked historical and constitutional support, emphasizing that the 14th Amendment was designed to provide an inclusive definition of citizenship rather than one based on bloodline.
Justice Ketanji Brown Jackson, in a concurring opinion, criticised the dissenting view, arguing that attempts to narrow the Citizenship Clause were inconsistent with both the amendment’s text and its historical purpose. Meanwhile, Justice Thomas, writing for the dissent, contended that the framers never intended automatic citizenship to apply to children born to individuals who owed allegiance to another country.
Civil rights groups welcomed the judgment, calling it a major victory for constitutional protections and immigrant communities. Legal advocates argued that overturning birthright citizenship would have left hundreds of thousands of children born annually in the United States vulnerable to statelessness or prolonged legal uncertainty. They said the decision preserves a constitutional principle that has remained intact for more than a century.
Trump reacted by expressing disappointment with the verdict but signalled that he would continue pursuing the issue through Congress. He argued that lawmakers should consider legislation to redefine the scope of birthright citizenship, although constitutional experts believe any such effort would face significant legal and political obstacles given the court’s interpretation of the 14th Amendment.
The ruling is widely regarded as one of the most consequential decisions of the Supreme Court’s 2025-26 term. It not only preserves a long-standing constitutional safeguard but also reinforces judicial precedent on one of the most contentious issues in America’s immigration debate, dealing a substantial blow to one of the Trump administration’s central immigration policy objectives.
