Trump’s global tariffs to face challenge before Supreme Court

THE US Supreme Court is set to hear arguments Wednesday on the legality of Donald Trump's unprecedented use of powers for sweeping global tariffs in a case striking at the heart of the president's economic agenda.

Since returning to the White House, Trump has invoked emergency economic powers to impose "reciprocal" tariffs over trade practices Washington deemed unfair, alongside separate duties targeting his country's biggest trading partners: Mexico, Canada and China.

But these tariffs, a key prong of his "America First" trade policy aimed at protecting and boosting US industries, swiftly faced legal challenges.

A lower court ruled in May that Trump exceeded his authority in imposing the duties, although the administration's appeal allowed them to temporarily stay in place.

The US Court of Appeals for the Federal Circuit ruled 7-4 in August that the levies were illegal -- affirming the lower court's finding -- prompting Trump to take the fight to the Supreme Court.

The top court's decision will have major ramifications, but this could take months.

The conservative-majority Supreme Court could find the tariffs illegal, blocking duties imposed on goods from countries worldwide. Or judges could affirm Trump's actions, opening the door to further levies.
