The U.S. Supreme Court ruled that President Donald Trump exceeded his authority by imposing broad tariffs under the International Emergency Economic Powers Act (IEEPA). The 6–3 decision restricted a key economic and foreign policy tool Trump had used to pressure other nations. In response, Trump announced on Friday that he would impose a new 10% tariff on all countries worldwide, using what he described as alternative legal powers.

Speaking at the White House, Trump sharply criticized the court, claiming some justices lacked the courage to do what he considered right for the country. He said foreign nations that had taken advantage of the United States were celebrating the ruling but warned their joy would be short-lived. Trump stated he would sign an executive order to implement the new tariffs and initiate multiple trade investigations under Section 301 of the 1974 Trade Act, which allows tariffs against unfair or discriminatory trade practices.

The Supreme Court’s decision significantly curtailed Trump’s ability to use tariffs as leverage in trade and diplomatic negotiations, a strategy he had relied on since his first year in office.
