Supreme Court Invalidates Trump's IEEPA Global Tariffs

The Supreme Court ruled that the International Emergency Economic Powers Act did not authorize the president's sweeping global tariff program, rejecting the administration's use of the statute to impose broad, general import taxes.

The ruling addressed a core separation-of-powers question: whether a statute granting emergency economic powers to the president can be stretched into an open-ended authority to set tariffs affecting the entire economy, a power the Constitution otherwise assigns to Congress. The decision limits how far emergency authorities can be used to bypass the ordinary legislative process for trade policy.

The Court's ruling invalidated the global IEEPA tariffs, marking a definitive legal defeat for that tariff program.
