The US Supreme Court, with a conservative majority, issued a decisive ruling against various global tariffs previously imposed by former President Donald Trump. The court's decision stemmed from a challenge to the authority granted under the International Emergency Economic Powers Act (IEEPA), asserting that this legislation does not provide the president with the power to impose tariffs unilaterally. This marks a significant judicial intervention in economic policy and presidential powers.

Former President Trump, who returned to office last year, was known for utilizing tariffs as a leverage point in trade negotiations, implementing aggressive tariffs on a range of US trading partners. These tariffs included retaliatory measures aimed at practices considered unfair by Washington, alongside specific tariffs targeting major partners such as Mexico, Canada, and China, primarily linked to illegal immigration and drug trafficking. The court's ruling could lead to a fundamental shift in how the US manages its trade relations and the president's authority over economic sanctions.

The Supreme Court's ruling signifies a critical stance against unilateral presidential powers in imposing trade tariffs, highlighting the need for Congressional approval. The court emphasized that if Congress had intended to give the president unique powers regarding tariff imposition, it would have explicitly stated so in the IEEPA. This judgment not only curtails Trump's fiscal strategies but may also set a precedent for future administrations regarding economic policies and international trade agreements.
