- Where it stands
- Decided
Decided 6-3 · June 27, 2025 · Opinion by Justice Barrett
- What it’s about
- This case addresses whether federal district courts possess the equitable authority to issue universal injunctions that block the enforcement of executive orders against non-parties nationwide.
- Who it affects
- Federal policies may now be blocked only as far as needed to fully protect the people or groups who sued. For example, an executive order may remain enforceable against nonparties unless they are covered by narrower relief or a class action.
Summary: written with AI from the case record.
What it's about
The Supreme Court held that such broad relief likely exceeds the traditional equitable powers granted to federal courts under the Judiciary Act of 1789.
The decision limits a remedy frequently used to stop federal executive actions nationwide while challenges proceed in court.
Question presented
Can a district court issue a nationwide (universal) injunction that blocks enforcement of a federal executive order beyond the specific parties involved in the lawsuit?
What the Court decided
Holding
Universal injunctions likely exceed the equitable authority that Congress has given to federal courts. The Court grants the Government’s applications for a partial stay of the injunctions entered below, but only to the extent that the injunctions are broader than necessary to provide complete relief to each plaintiff with standing to sue. Pp. 4– 26. (a) The issue raised by these applications—whether Congress has granted federal courts authority to universally enjoin the enforcement of an executive order—plainly warrants this Court’s review. On multiple occasions, and across administrations, the Solicitor General has asked the Court to consider the propriety of this expansive remedy.

From the opinions
“Universal injunctions likely exceed the equitable authority that Congress has given to federal courts.”
“The Court’s decision to permit the Executive to violate the Constitution with respect to anyone who has not yet sued is an existential threat to the rule of law.”
What's next
Lower courts must narrow the injunctions to relief needed for each plaintiff with standing to sue. Agencies may enforce the executive order against people outside that protected group, unless another court order or properly certified class action applies.
