Court Says No to Trump’s Use of Emergency Law as a Trade Weapon

A U.S. appeals court has said a firm “no” to Donald Trump’s use of a national emergency law as a trade weapon. The court ruled that his imposition of global tariffs under the International Emergency Economic Powers Act (IEEPA) was illegal, delivering a major blow to his trade legacy.
The ruling clarifies that the IEEPA is a tool for national security and foreign policy crises, such as sanctioning hostile states, not for managing economic relationships with trading partners. The court found that the former president’s attempt to use it for tariffs was an overreach that was not supported by the law’s text or history.
This decision could unravel the delicate web of trade deals the Trump administration pieced together. These agreements were often coerced by the threat of the IEEPA tariffs. With that threat now legally voided, the deals themselves have lost their primary enforcement mechanism.
The former president will appeal to the Supreme Court, where the case will become a landmark battle over executive power. The justices will be asked to define the limits of a president’s ability to act unilaterally in the economic sphere, a ruling that will set a precedent for future administrations.
