A man who paid extra for two pairs of Nike Vomero sneakers on account of President Donald Trump’s now-illegal International Emergency Economic Powers Act tariffs is suing Nike for a refund.
Through attorneys Jennifer Rust Murray and Toby J. Marshall of Terrell Marshall Law Group, James Dunn filed a complaint in an Oregon federal district court on Tuesday. He accuses Nike of unjust enrichment and unlawful trade practices and seeks to have his case certified as a nationwide class action on behalf of people who paid more for Nike products while the IEEPA tariffs were in effect from June 1, 2025, through Feb. 24, 2026.
Dunn v. Nike could have sizable ramifications well beyond Nike and the sports industry. Companies that sell goods in numerous markets are now able to secure refunds through U.S. Customs and Border Protection. Whether those companies share all or some of those refunds with consumers remains to be seen and is likely to trigger litigation.
The U.S. Supreme Court’s Feb. 20, 2026, ruling in Learning Resources Inc. v. Trump held that IEEPA—which generally authorizes the president to regulate economic transactions in the event of economic emergencies—didn’t authorize Trump to impose tariffs. The ruling meant the tariffs shouldn’t have been imposed and thus were unlawful from the beginning.
