Supreme Court Defies Trump: Birthright Citizenship Upheld in Landmark 6-3 Ruling

The Supreme Court has slammed the brakes on President Donald Trump’s most aggressive immigration gambit, ruling that birthright citizenship cannot be erased by executive order.

In a 6-3 decision handed down on June 30 — just days before America’s 250th anniversary — the justices struck down Trump’s inauguration-day directive that sought to deny citizenship to babies born on U.S. soil whose parents lack citizenship or green cards. The ruling marks the second major rebuke of Trump’s expansive executive authority, following the court’s earlier rejection of his signature tariffs.

Chief Justice John Roberts, writing for the majority, declared that children born to parents unlawfully or temporarily in the United States are fully protected by the 14th Amendment’s citizenship clause.

“Citizenship, then and now, was the right to have rights — to freely participate in our political community,” Roberts wrote. “The Framers of the Fourteenth Amendment extended that promise to ‘every free-born person in this land.’ We keep that promise today.”

Three conservative justices — Clarence Thomas, Samuel Alito, and Neil Gorsuch — dissented. Thomas warned the decision “devalues” American citizenship and is unlikely to “stand the test of time.”

Justice Brett Kavanaugh, while concurring with the result, offered a narrower view: he argued Trump’s order violated a 1952 immigration statute rather than the Constitution itself, calling the constitutional question “far more complicated than the statutory issue.”

Trump’s order — signed on Day One of his second term — would have stripped roughly 255,000 newborns annually of U.S. citizenship, about 6% of all births, according to the Migration Policy Institute.

The policy was immediately challenged by expectant parents, immigrant rights groups, and 22 state attorneys general. Among the plaintiffs: a Honduran asylum-seeker known as “Barbara” and a Taiwanese mother of four, “Susan,” who built her life in America on student visas.

“My baby has the right to citizenship and a future in the United States,” Susan said in court filings.

The 14th Amendment’s citizenship clause — adopted after the Civil War to overturn the infamous Dred Scott decision — states: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.”

During oral arguments, Roberts dismissed Trump’s claims that “birth tourism” and national security concerns justified rewriting that guarantee. “It’s a new world,” Roberts said. “It’s the same Constitution.”

The ruling preserves one of America’s most fundamental constitutional principles — but the 6-3 split signals the fight is far from over. For now, the promise of birthright citizenship remains intact, just in time for the nation’s semiquincentennial.
