The U.S. Supreme Court has delayed its ruling on the legality of President Donald Trump's global tariffs, imposed under the International Emergency Economic Powers Act. The case, which challenges presidential authority and has significant economic implications, was heard in November. Lower courts had previously ruled against the administration. Businesses and states affected by the tariffs, as well as international trading partners, await the decision, which could impact global trade and potentially trigger billions in refunds if the tariffs are struck down.
