Episode notes
Legal Limits on Tariff Authority
- Trump's tariffs relied on the International Emergency Economic Powers Act, a statute usually used for sanctions, not tariffs.
- Courts found this law did not grant unbounded tariff power to the president for broad trade restrictions.
Court Pauses Tariff Invalidations
- The Court of Appeals paused an earlier ruling that had invalidated many Trump tariffs.
- This legal pause means tariffs stay on while the appeals are considered, maintaining uncertainty.
Court Finds Tariff Justifications Weak
- The court ruled that tariffs on general imports don't fit emergency powers and are beyond congressional delegation.
- Tariffs on Canada, Mexico, and China regarding fentanyl didn't directly address emergencies, weakening legal justification.
