On August 29, 2025, the U.S. Court of Appeals for the Federal Circuit ruled in a 7-4 decision that most of President Donald Trump’s emergency tariffs, imposed under the International Emergency Economic Powers Act (IEEPA), are illegal, per Marketbit.io and. The court found that IEEPA does not grant the president “unbounded authority” to impose tariffs, as this power is constitutionally reserved for Congress, per. The ruling covers “reciprocal” tariffs on nearly all imports and fentanyl-related levies on China, Canada, and Mexico, but stays enforcement until October 14, 2025, allowing time for a Supreme Court appeal, per.
