Episode notes
Court Limits Presidential Tariff Power
- The Supreme Court ruled 6-3 that the president cannot use the IEPA to impose sweeping global tariffs without explicit congressional authorization.
- Justices said broad regulatory language does not equate to a power to impose taxes or tariff-like measures.
IEPA Was The Legal Basis For Mass Tariffs
- The Trump administration relied on the International Emergency Economic Powers Act (IEPA) to declare emergencies and impose tariffs on about 90 countries.
- The administration justified tariffs citing large trade deficits and the fentanyl crisis as emergencies.
Regulatory Language Isn’t A Blank Check
- The Court's majority emphasized that vague regulatory authority cannot be stretched into a taxation or tariff power.
- The opinion compared other regulators' powers to show that 'regulate' doesn't automatically permit imposing taxes.
