Episode notes
Who Controls Tariff Power
- The key legal question is who can lawfully levy tariffs: the president or Congress.
- The Supreme Court will decide whether Trump's sweeping tariffs exceed constitutional limits on executive power.
Constitution Put Tariffs With Congress
- The Constitution gives Congress exclusive authority to levy duties and regulate foreign commerce.
- Founders intentionally put tariff authority in Congress to check unilateral executive use of economic power.
Delegations Exist But Are Narrow
- Congress has delegated specific, narrow tariff authorities with process and limits like Section 232.
- The Trump administration seeks a broader, unbounded authority under the International Emergency Economic Powers Act (IEPA).
