A federal appeals court has ruled most of Donald Trump's tariffs are an overreach of his use of emergency powers as president.
The so-called reciprocal tariffs - imposed on nearly every country the US trades with - are being illegally imposed, the US Court of Appeals said on Friday.
The decision upholds a May ruling from the Court of International Trade, which also rejected Trump's argument that his global tariffs were permitted under an emergency economic powers act.
The court did not halt the tariffs but instead said they would remain in place until mid-October, setting up a further legal challenge in the US Supreme Court.
There's still a lot of unknowns, but here's what we understand so far about the ruling - and what it could mean for the US president's flagship policy.
