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

The 6-3 decision centres on tariffs imposed under an emergency powers law, including the sweeping “reciprocal” tariffs he levied on nearly every other country. The high court ruled his use of an emergency powers law to set import duties without Congress was illegal.

Trump told a news conference he's “absolutely ashamed” of justices who voted to strike down his tariffs, calling the decision “deeply disappointing.” His loss before the conservative-majority high court came despite a series of short-term Trump wins that have allowed him to move ahead with key aspects of his broad agency.

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. (AP) RD RD

Emergency powers invalidation limits executive authority to impose unilateral tariffs, nullifying sweeping reciprocal import duties. The executive's imposition of sweeping 'reciprocal' import duties under a claimed emergency powers statute was found unlawful; the tariffs were invalidated because setting import duties required clear congressional authorization rather than unilateral emergency proclamations, signaling a legal limit on executive authority to alter statutory tariff schemes by emergency declaration.
