Supreme Court Limits Nationwide Injunctions; Kennedy Mocks Justice Jackson

The U.S. Supreme Court has ruled that federal district courts may no longer issue nationwide, or “universal,” injunctions that block federal policies across the entire country. The decision reins in a legal tool increasingly deployed in high-profile policy disputes. Justice Ketanji Brown Jackson dissented from the majority opinion, arguing that the limitation weakens a vital check on executive authority. Republican Senator John Kennedy of Louisiana publicly applauded the ruling, declaring that the Court had “turned the universal injunction into fish food.” Kennedy added that Justice Jackson was “mad as a bag of cats,” a remark that highlights the sharp partisan response to the Court’s latest move.
