OTTAWA AND WASHINGTON, D.C. — The U.S. Supreme Court ruled on Friday that the emergency authority that U.S. President Donald Trump relied on to impose sweeping tariffs on Canada “falls short” and said the president violated federal law when he imposed the trade barriers. The decision, which was written by U.S. Supreme Court Chief Justice John Roberts, was a 6-3 ruling. Last year, Trump imposed tariffs on countries around the world using a law meant for national emergencies called the International Emergency Economic Powers Act or IEEPA for short. Friday’s ruling does not impact the Section 232 tariffs that the president has imposed on Canadian steel, aluminum and lumber. “The decision of the Supreme Court of the United States strengthens Canada’s position that the tariffs imposed by the United States under the IEEPA are unjustified,” he said, in a post on X.
