In a major 6–3 decision, the Supreme Court ruled that President Donald Trump exceeded his authority by using a 1977 emergency law to impose sweeping global tariffs. The ruling invalidates key “reciprocal” tariffs and certain 25 percent duties on imports from China, Canada and Mexico — potentially mandating the return of more than $100 billion in collected revenue.

US President Donald Trump has announced a new 10&#37 global tariff under Section 122 authority, just hours after the Supreme Court ruled 6–3 against his use of emergency powers to impose sweeping tariffs. Calling the decision “deeply disappointing,” Trump insisted the ruling did not eliminate presidential tariff authority and vowed stronger action. He accused certain justices of lacking courage and claimed foreign nations were celebrating the verdict.
