Episode notes
Court Limits Presidential Tariff Power
- The Supreme Court struck down the statutory authority Trump used for broad global tariffs, creating immediate legal limits.
- H.J. Mai says this injects uncertainty and may pause many tariffs while the administration seeks alternatives.
Plan For A Temporary Tariff Gap
- Expect the White House to use other statutory tools or seek Congressional backing to restore tariffs.
- Prepare for a gap of months without tariffs as alternative processes are implemented, per Wilbur Ross.
Judiciary Reasserts Checks And Balances
- The ruling shows the judiciary can act as a check even when Congress largely defers to the White House.
- H.J. Mai sees the decision as a significant constraint on executive overreach despite presidential resolve.
