On June 27, 2025, in an Opinion authored by Justice Amy Coney Barrett, the United States Supreme Court determined that “universal injunctions,” injunctions issued by district judges that apply nationwide, “likely exceed the equitable authority that Congress has given to federal courts.” In Trump v. CASA, Inc., the Supreme Court, with a 6-3 vote, concluded that district courts do not have authority to issue universal injunctions which seek to prohibit the enforcement of a law or policy against anyone nationwide. The decision limits the relief afforded by the district courts in consolidated matters to only the parties in those actions.
By prohibiting the use of “universal injunctions” in federal courts, litigants already have started to utilize another procedure to seek the relief they seek – class actions. Class actions are a special procedure provided by both federal and state law that allows one or more class representatives to file suit and seek to represent the interests of other similarly situated individuals or companies. Prior to the Supreme Court’s ruling in Trump v. CASA, Inc., a single litigant could apply for a universal injunction through an individual action. Now that the Supreme Court has declared that process unavailable for application of an injunction nationwide, class actions may be the procedural process litigants attempt to use to achieve that same purpose. It remains to be seen whether class actions will be an effective way to achieve broader relief for individuals impacted by government policies.
