Supreme Court Strikes Down Key Trump Administration Tariffs

On February 20, 2026, the U.S. Supreme Court issued a 6-3 decision in Learning Resources, Inc. v. Trump, holding that tariffs imposed by the Trump administration under the International Emergency Economic Powers Act ("IEEPA") exceeded the authorities Congress delegated to the President under that law. The Trump administration rolled out the tariffs subject to the decision in a series of executive orders last spring, asserting that the United States was experiencing national emergencies relating to fentanyl trafficking (resulting in tariffs imposed on imports from China, Mexico, and Canada) and the national trade deficit (resulting in so-called "reciprocal" tariffs of at least 10% on imports from most countries and higher rates of 25%-100% for certain countries).
