Customers sue Costco for tariff refunds

A group of customers has filed a class-action lawsuit against Costco, seeking refunds for tariffs that the U.S. Supreme Court ruled illegal. The tariffs were imposed under the 1977 Emergency Powers Act, which the court stated was improperly used to bypass Congress, violating the separation of powers. The International Trade Court ordered the government to refund around $166 billion in collected tariffs, but the process and timeline remain uncertain as the White House resists the refunds.
