WASHINGTON — The Supreme Court delivered a major blow to President Donald Trump, ruling Friday that he exceeded his authority when imposing sweeping tariffs using a law reserved for a national emergency. The justices, divided 6-3, held that Trump's aggressive approach to tariffs on products entering the United States from across the world was not permitted under a 1977 law called the International Emergency Economic Powers Act (IEEPA). The ruling invalidates many, but not all, of Trump’s tariffs.
