<h1>Federal decision limits president's power to declare national emergencies and impose sweeping import tariffs, keeps tariffs temporarily in place</h1> A federal appeals court held that the president lacked statutory authority to declare national emergencies and unilaterally impose broad import tariffs on nearly all trading partners, largely affirming a lower court's decision but reversing the immediate vacatur so the tariffs remain in place pending further review. The ruling preserves the administration's ability to seek Supreme Court review and notes alternative, more constrained statutory avenues for imposing duties that would limit the pace and scope of tariff actions. The decision leaves existing tariffs effective for now while creating legal uncertainty and potential economic disruption.
