History

Historical Context

The International Emergency Economic Powers Act (IEEPA), enacted on December 28, 1977, empowers the U.S. President to regulate international commerce during national emergencies. This law has been invoked by various administrations, notably Donald Trump, who imposed tariffs on imports citing national security threats. Current legal challenges question the extent of executive power in trade, potentially reshaping U.S. trade policy and congressional authority.
