History

Historical Context

The International Emergency Economic Powers Act (IEEPA), enacted in 1977, allows the U.S. President to regulate trade during national emergencies. In 2019, President Trump invoked IEEPA to impose tariffs, sparking legal challenges reminiscent of the 1930 Smoot-Hawley Tariff, which intensified economic tensions. These rulings could significantly influence U.S. trade policy and relations with countries like Canada and China.
