A federal appeals court has delivered a clear message to President Donald Trump: an anti-terrorism and national security law cannot be repurposed to fight a trade war. The court struck down his administration’s use of the International Emergency Economic Powers Act (IEEPA) to justify global tariffs, calling the move illegal.
The ruling dissects the 1977 law, concluding it was created to give presidents the power to freeze assets and impose sanctions on enemies of the state, not to set duties on goods from allied nations. The court found Trump’s justification—that trade deficits and fentanyl constituted a national emergency—to be a stretch of the law’s intent beyond its breaking point.
The decision throws global trade relations into a state of flux. Agreements made with the European Union, Japan, and others to get out from under these tariffs now appear to be built on an unlawful premise. The court’s finding validates the position of many legal experts who argued from the beginning that the tariffs were an overreach of executive power.
An appeal to the Supreme Court is expected, which will prolong the uncertainty for businesses and consumers. The case is now set to become a landmark test of the separation of powers, potentially defining the boundaries of presidential authority in international economic affairs for decades to come.
