A federal trade court on Wednesday blocked President Donald Trump from imposing sweeping tariffs on imports under an emergency-powers law. The ruling from a three-judge panel came after several lawsuits arguing Trump has exceeded his authority, left U.S. trade policy dependent on his whims and unleashed economic chaos.

At least seven lawsuits are challenging the levies, the centerpiece of Trump's trade policy. Tariffs must typically be approved by Congress, but Trump says he has the power to act because the country's trade deficits amount to a national emergency.
