US federal court deems Trump administration's global tariffs unlawful; White House appeals decision

A U.S. federal court ruled that President Trump exceeded his authority by imposing broad tariffs under the 1977 International Emergency Economic Powers Act. This decision, which would invalidate significant parts of the administration's tariff agenda, including a 10% import tax and reciprocal duties, was immediately appealed by the White House. The administration contends the ruling improperly limits presidential power in foreign and economic policy.
