History

Historical Context

Enacted on December 28, 1977, the International Emergency Economic Powers Act (IEEPA) allows the U.S. President to regulate international commerce during national emergencies. This act emerged from concerns over unchecked executive power, particularly following the Trading with the Enemy Act of 1917. President Trump notably invoked IEEPA to impose tariffs on nations like Nauru, raising significant constitutional debates over executive authority.
