In its judgement, the US Court of Appeals for the Federal Circuit rejected Trump’s argument that the tariffs were permitted under his emergency economic powers, calling the levies “invalid as contrary to law”.

“Whenever Congress intends to delegate to the President the authority to impose tariffs, it does so explicitly, either by using unequivocal terms like tariff and duty, or via an overall structure which makes clear that Congress is referring to tariffs,” the judges wrote.
The ruling comes in response to two lawsuits filed by small businesses and a coalition of US states.

The ruling on Friday does not apply to other tariffs, like those imposed on steel and aluminium, which were imposed under a different presidential authority.
In May, the New York-based Court of International Trade declared the tariffs were unlawful. That decision was put on hold for the
