The Trump administration on Tuesday filed a notice of appeal with the U.S. Court of International Trade challenging a judge's order that U.S. Customs refund $166 billion in global tariffs imposed under the International Emergency Economic Powers Act (IEEPA).

The Justice Department argues the trial judge lacked authority to direct refunds to all importers who paid the tariffs, regardless of whether they sued to recover payments.
