WASHINGTON (AP) — The Supreme Court struck down President Donald Trump’s far-reaching global tariffs Friday, handing him a stinging loss that sparked a furious attack on the court he helped shape.

The decision could have ripple effects on economies around the globe after Trump’s moves to remake post-World War II trading alliances by wielding tariffs as a weapon.

Trump pledged to impose a new global 10% tariff.

The court’s ruling found tariffs that Trump imposed under an emergency powers law were unconstitutional, including the sweeping “reciprocal” tariffs he levied on nearly every other country.

The majority found that it is unconstitutional for the president to unilaterally set and change tariffs because taxation power clearly belongs to Congress. “The Framers did not vest any part of the taxing power in the Executive Branch,” Chief Justice John Roberts wrote.

Justices Brett Kavanaugh, Samuel Alito and Clarence Thomas dissented.
