Washington, Feb 20 (AP) The Supreme Court struck down President Donald Trump's far-reaching global tariffs on Friday, handing him a significant loss on an issue crucial to his economic agenda.

The decision centres on tariffs imposed under an emergency powers law, including the sweeping “reciprocal” tariffs he levied on nearly every other country.

It's the first major piece of Trump's broad agenda to come squarely before the nation's highest court, which he helped shape with the appointments of three conservative jurists in his first term.

The Republican president has been vocal about the case, calling it one of the most important in US history and saying a ruling against him would be an economic body blow to the country. But legal opposition crossed the political spectrum, including libertarian and pro-business groups that are typically aligned with the GOP.

Emergency powers limits curb broad presidential tariffs, invalidating sweeping reciprocal trade measures and reshaping trade policy authority. The Supreme Court found that tariffs enacted under asserted emergency statutory powers-including widely applied reciprocal tariffs-exceeded the President's lawful authority, clarifying statutory limits on unilateral tariff measures and signaling judicial constraints on executive use of emergency powers for sweeping trade regulation.
