The Supreme Court struck down Trump’s “Liberation Day” tariffs in February, prompting the administration to refund approximately $100 billion of the $166 billion collected. A hearing before Judge Richard Eaton at the U.S. Court of International Trade addressed potential class-action expansion of those refunds, while 25 states filed separate suits challenging newer tariff actions. The case centers on procedural compliance with the ruling and the scope of restitution to affected businesses.
