In this episode of Reasonably Speaking, ALI President David Levi moderates a timely and incisive discussion on nationwide (or universal) injunctions—court orders that extend relief beyond the parties in a case, often halting federal policy nationwide. Featuring legal scholars William Baude and Samuel Bray, along with Judge Robin Rosenberg and former Judge Gregg Costa, the conversation explores the constitutional debates, practical consequences, and political implications of these powerful judicial tools. From forum shopping and the shadow docket to potential reforms like three-judge courts, this panel examines whether the nationwide injunction is a necessary check—or a threat to judicial legitimacy.
