Supreme Court ruled 6-3 district courts cannot issue nationwide injunctions, eliminating key civil rights enforcement tool
The Supreme Court ruled 6-3 on June 27, 2025, in Trump v. CASA, Inc. that federal district courts lack authority to issue nationwide injunctions protecting people beyond named parties in a case. The majority opinion, written by Justice Barrett, held that the Judiciary Act of 1789 authorizes only injunctions necessary to provide complete relief to named plaintiffs. The ruling immediately allowed Trump's birthright citizenship executive order to partially take effect against non-parties in states that had not filed suit, while courts continued finding the order unconstitutional.
