The U.S. Supreme Court has delivered a significant blow to President Donald Trump's trade policy, ruling that his imposition of sweeping tariffs on imports was illegal. The court determined that Trump overstepped his authority by invoking the International Emergency Economic Powers Act (IEEPA) for measures that should only apply during national emergencies. This ruling has implications for international trade and particularly for countries exporting to the U.S., including close allies like the UK, who faced substantial economic consequences due to these tariffs.

The tariffs, first announced by Trump on what he called "liberation day" in April, encompassed a broad range of goods and resulted in increased costs for businesses and consumers alike. Although a temporary trade agreement with the UK alleviated some pressures, many firms continued to face higher prices. The ruling signifies a major legal setback for Trump, as it challenges the executive power to unilaterally impose tariffs without Congressional approval, a concern raised by many trade analysts and economists.

In response to the court's ruling, Trump has indicated he plans to circumvent the decision by imposing a 10% levy within three days. This maneuver raises further questions about the administration's approach to trade and the future of U.S. international relations. The ongoing struggle over tariffs highlights the contentious nature of trade policy in the current political climate, and how economic decisions are deeply intertwined with legal and diplomatic considerations.
