Trump promises to impose tariffs through 'alternatives' after U.S. Supreme Court strikes down IEEPA tariffs 

OTTAWA AND WASHINGTON, D.C. — Just hours after the United States Supreme Court struck down U.S. President Donald Trump’s use of emergency powers to impose tariffs, the president vowed to use other laws to impose global levies.

The highest court ruled on Friday that the emergency authority that U.S. President Donald Trump relied on to impose sweeping tariffs on Canada and countries around the world “falls short” and said the president violated federal law when he imposed the trade barriers.
