WASHINGTON
The US Supreme Court on Thursday set Nov. 5 to hear arguments on whether President Donald Trump lawfully used emergency powers to impose sweeping worldwide tariffs.
It came after a federal appeals court last month ruled 7-4 that Trump exceeded his authority under the International Emergency Economic Powers Act (IEEPA), a 1977 law allowing economic sanctions against “unusual and extraordinary” threats.
Several lower court rulings, including one Aug. 29 from the US Court of Appeals for the Federal Circuit, concluded that Trump illegally overstepped the authority of Congress to impose worldwide tariffs in which he slapped steep duties on imports from many countries earlier in the year.
In February, Trump announced tariffs on Canada, China and Mexico, later expanding them into a 10% global baseline tariff.
