US Appeals Court Rejects Trump Bid to Delay $130B Tariff Refund Litigation

The Federal Circuit's decision to deny the Trump administration's request for a four-month delay marks a critical procedural defeat for the executive branch, signaling that the judiciary is unwilling to grant breathing room in the wake of the Supreme Court's substantive invalidation of global tariffs. This ruling is a green light for corporate legal departments and small business coalitions that have been waiting to reclaim billions in duties paid under policies now deemed illegal. By rejecting the administration's bid for a stay, the court has effectively accelerated what is likely to be one of the largest and most complex refund litigations in the history of the US Court of International Trade.

The scale of the potential liability for the US government is staggering. As of late 2025, the global tariffs in question had generated more than $130 billion in revenue. While the Supreme Court's earlier ruling did not affect sector-specific tariffs—such as those on steel or aluminum—the invalidation of the broader global tariff regime has opened a massive fiscal hole. For the administration, the four-month delay was likely a strategic attempt to manage this fiscal impact or to reorganize a legal defense strategy that has been fundamentally undermined by the high court's decision. However, the Federal Circuit agreed with the plaintiffs that such a delay was plainly unreasonable, particularly given that the Supreme Court had already signaled that the underlying policy was inappropriate.

The rush for refunds is already well underway, with major multinational corporations leading the charge. FedEx and Costco have emerged as early and aggressive litigants, with Costco's challenge notably predating the Supreme Court's final decision. They have been joined recently by other global giants like Dyson and L'Oréal, illustrating that the impact of these tariffs spanned across logistics, retail, consumer electronics, and cosmetics. The Liberty Justice Center, which represents a coalition of small businesses, estimates that more than 900 refund claims have already been filed in federal court, with some analysts suggesting the final number of corporate entities involved could exceed 1,000.
