The Globe and Mail reports in its Saturday edition that President Donald Trump's protectionist trade policy may face legal challenges early next year. The Globe's Mark Rendell writes that in November, the U.S. Supreme Court heard cases challenging Mr. Trump's use of the International Emergency Economic Powers Act to impose tariffs. The Supreme Court is likely to declare the IEEPA tariffs illegal, following two lower court decisions. A ruling is expected this month or next. A negative decision would highlight the chaotic manner in which Mr. Trump has advanced his protectionist agenda over the past year, potentially causing complications for the U.S. government, which has collected over $130-billion (U.S.) in tariff revenue that may need to be refunded. Holland & Knight lawyer Patrick Childress says that if the court rules to strike down the IEEPA tariffs, "there would be some period where the overall tariff burden on goods being imported into the United States would be lower." He doubts that period will last very long because "the administration has the tools it needs to recreate all or substantially all of the IEEPA tariff framework using other statutory authority."
