US Supreme Court Strikes Down President Trump’s IEEPA Tariffs

On Friday, the US Supreme Court struck down President Donald Trump’s sweeping tariffs pursued under the International Emergency Economic Powers Act (IEEPA), Reuters reported (2-20-26).

In a 6–3 ruling authored by Chief Justice John Roberts, the justices upheld a lower court decision finding that IEEPA does not authorize the president to impose tariffs.

The Trump administration has not released tariff collection data since December 14, but Penn-Wharton Budget Model economists estimated Friday that more than $175 billion had been collected under IEEPA. It was not immediately clear when IEEPA tariff assessments and collections at ports of entry would halt or how any refund process might work.

Trump said “other alternatives” are available to pursue tariffs and announced a 10% global tariff under Section 122 of the Trade Act of 1974—separate from the authority at issue in the case—“over and above our normal tariffs already being charged.”
