Supreme Court strikes down Trump birthright-citizenship order

The Supreme Court on June 30 struck down Donald Trump’s executive order seeking to end birthright citizenship, delivering a major constitutional defeat in a fight over who is considered a U.S. citizen at birth.

In a 6-3 ruling, the court rejected the administration’s attempt to deny citizenship to children born in the United States to undocumented immigrants and some temporary foreign residents, according to published coverage. The decision preserves the long-standing reading of the 14th Amendment’s Citizenship Clause and leaves in place the rule that nearly all people born on U.S. soil are citizens at birth.

Trump signed the order on his first day back in office in 2025, setting off an immediate legal battle over whether a president can narrow a constitutional guarantee through executive action. Lower courts blocked the policy before it could take effect, and the Supreme Court’s ruling now makes clear the order cannot stand.

The ruling

Chief Justice John Roberts wrote the majority opinion, according to published coverage. Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented, while Justice Brett Kavanaugh concurred in the judgment.

The majority reaffirmed the conventional understanding of the 14th Amendment’s Citizenship Clause, which has long been read to protect nearly all people born in the United States. Coverage also ties the decision to the Court’s earlier interpretation in Wong Kim Ark, a landmark precedent that has underpinned birthright citizenship for generations.

The case turned on the phrase “subject to the jurisdiction thereof” in the amendment. The administration argued for a narrower reading that would have excluded children born in the United States to people in the country illegally or temporarily. The court rejected that effort.

How the case got here

Trump’s executive order was part of an early push in his return to office in 2025. It targeted birthright citizenship as a way to deny automatic citizenship to some children born in the United States, a move that immediately drew litigation.

The legal fight centered on whether the president could unilaterally change a rule rooted in the Constitution itself. Advocates for the order argued for a narrower interpretation of the Citizenship Clause, while opponents said the 14th Amendment had already settled the question for generations.

Lower courts stopped the policy before it could be implemented. That meant the order never took effect, but it still became a major test case over the limits of presidential power and the scope of the 14th Amendment.

Who is affected

The policy would have affected children born in the United States to undocumented immigrants and to people in the country temporarily, including some foreign residents covered by the administration’s order. Coverage says the issue carries the potential to affect hundreds of thousands of annual births, underscoring the scale of the dispute.

Because the order was blocked before implementation, the court’s decision preserves the status quo rather than reversing a policy already in force. For families who would have been affected, the ruling leaves the existing birthright citizenship rule intact.

The practical effect is straightforward: nearly all people born in the United States remain citizens from birth.

Why it matters

The ruling is not just an immigration case. It is also a major statement about the limits of presidential authority and the durability of constitutional precedent.

By rejecting Trump’s order, the court reinforced that a president cannot use executive power to override a long-settled reading of the Constitution. That makes the decision a significant marker in the broader fight over executive power.

It also lands in a politically charged part of the immigration debate. Trump made the order a signature move early in his return to office, and the case quickly became a test of whether his administration could turn a campaign promise into federal policy.

The court’s decision also preserves a rule that has been treated as settled law for generations. By tying its reasoning to earlier precedent, the majority signaled that any effort to end birthright citizenship would face an exceptionally high legal bar.

What happens next

The ruling may still trigger new disputes over implementation and related litigation, even though the core effort to end birthright citizenship has been rejected.

Coverage says Trump could also seek congressional action to change citizenship rules, though any such effort would face separate political and constitutional hurdles.

Lower courts and federal agencies will now have to align pending cases and internal guidance with the Supreme Court’s decision. For the moment, the constitutional rule remains unchanged: almost everyone born in the United States is a citizen at birth.

The case also leaves open the broader question of how far a president can go in trying to reshape immigration policy through executive orders when the underlying issue is anchored in constitutional text. That question is likely to continue shaping litigation even after this ruling.

For now, the Supreme Court has drawn the clearest available line: birthright citizenship remains in force, and Trump’s attempt to end it cannot move forward.
