The US Supreme Court has ruled that President Donald Trump overstepped his powers when he imposed sweeping global tariffs last year.
In its 6-3 decision, the court ruled that Trump could not use a 1977 law - the International Emergency Economic Powers Act (IEEPA) - to levy taxes on imports from nearly every country in the world.
The ruling left open the possibility of consumers and businesses being given refunds for the estimated $130bn generated by the tariffs - a prospect that the high court did not weigh in on but is likely to end up in another court battle.
Hours after the decision was released, Trump signed a proclamation using an alternative law, Section 122 of 1974's Trade Act, that would let him put a new 10% temporary tariff on goods from all countries.
Here's what to know about what comes next on tariffs and what questions still remain.
