Trump's DOJ has until Friday to decide on moving a tariff refund case to the Court of International Trade, the first deadline since the Supreme Court decision.

The Trump administration’s Department of Justice is nearing its first big legal deadline in the wake of the U.S. Supreme Court ruling that President Donald Trump’s tariffs issued under the International Emergency Economic Powers Act are illegal.

The DOJ needs to weigh in by Friday on one of the first legal fights over refunds in which plaintiffs are asking for expedited payment of tariff refunds through the Court of International Trade (CIT), which has typically handled tariff cases.

Trade attorneys have told CNBC there are upwards of 2,000 cases that have been filed by companies suing for tariff refunds at the CIT. Back in December, the CIT put a stay on the cases until after the Supreme Court announced its decision.
