Episode notes
Unprecedented Use Of IEPA For Tariffs
- President Trump used the International Emergency Economic Powers Act (IEPA) to impose unprecedented emergency tariffs on Canada, Mexico, and China.
- The IEPA use marked a radical expansion of executive trade power with sweeping global tariffs in April.
Separation Of Powers At Stake
- Cato frames the case as a separation-of-powers dispute over Congress's exclusive tariff power.
- The core statutory phrase is whether "regulate importation" allows the president to set uncapped tariffs.
IEPA Lacks Traditional Tariff Safeguards
- Existing tariff statutes sit in Title 19 and include procedural and substantive limits like investigations and time caps.
- IEPA lacks those checks, enabling a president to declare emergencies and act broadly without usual safeguards.
