The Supreme Court heard oral arguments in two consolidated cases brought by small businesses and 12 states challenging President Trump’s authority to impose tariffs on imported goods. The cases focus on whether the president’s use of the International Emergency Economic Powers Act (IEEPA) grants him the power to impose these tariffs.
President Trump invoked the IEEPA, which authorizes the president to act in response to unusual or extraordinary threats to national security, foreign policy, or the U.S. economy, including threats originating partly outside the country. Under this act, during a national emergency, the president can regulate the import or export of property involving any foreign country’s interest.
The ruling will affect every American consumer and business, as well as all foreign nations trading with the United States.
"The major questions doctrine bars the president from making economic decisions without clear authorization from Congress."
This case highlights the tension between executive authority and congressional control over major economic policies.
