The core legal argument for Donald Trump’s widespread tariffs has been rejected by a U.S. appeals court, which found his declaration of a “national emergency” over trade deficits to be an invalid reason to impose duties under the International Emergency Economic Powers Act (IEEPA).
In a 7-4 vote, the court sided with challengers who argued the 1977 law was never meant to be a tool for broad economic protectionism. The ruling stated that the IEEPA’s powers are for specific national security crises, and using it for general trade purposes “exceeds the authority” delegated to the president by Congress.
The decision has thrown Trump’s transactional trade diplomacy into turmoil. Numerous agreements with allies were predicated on the administration’s ability to impose these IEEPA tariffs. With that authority now stripped by the court, the leverage used to secure those deals has vanished, making their future uncertain.
The battle is set to continue at the Supreme Court. However, this ruling marks a pivotal moment in the debate over the scope of executive power in the modern era. It also creates a potential financial liability for the government, as the court ordered a review of whether billions in collected tariffs must be returned.
