Here’s what to know about the court ruling striking down Trump’s tariffs

A federal appeals court said the president overstepped his authority when he imposed sweeping import duties

Donald Trump suffered the biggest defeat yet to his tariff policies on Friday, as a federal appeals court ruled he had overstepped his presidential powers when he enacted punitive financial measures against almost every country in the world.

In a 7-4 ruling, the Washington DC court said that while US law “bestows significant authority on the president to undertake a number of actions in response to a declared national emergency”, none of those actions allow for the imposition of tariffs or taxes.
