Supreme Court voids IEEPA authority used to impose recent UK tariffs
What happened
- The Supreme Court ruled on February 20, 2026, that IEEPA does not authorize tariffs, voiding the legal basis for Trump’s recent import duties. (supremecourt.gov) - U.S. Customs and Border Protection said it had calculated $35.46 billion in refunds on 8.3 million shipments as of May 11. (cnbc.com) - U.S. Court of International Trade filings continue to track refund processing, with companies including Walmart and Cardinal Health seeking repayment. (finance.yahoo.com)
Why it matters
The Supreme Court’s February 20 ruling did two things at once: it ended one of the Trump administration’s main legal routes for imposing broad tariffs, and it opened the door to a refund fight that is now running through the customs system and the trade court. (supremecourt.gov) In *Learning Resources v. Trump*, the court held 6-3 that the International Emergency Economic Powers Act does not authorize the president to impose tariffs. The opinion covered both the drug-trafficking tariffs aimed at Canada, Mexico and China and the broader “reciprocal” tariffs applied across trading partners. (cnbc.com) That ruling matters because IEEPA had been used as the administration’s emergency-law basis for sweeping import duties. (finance.yahoo.com) The court’s decision sent the case back for refund questions, and importers began filing claims through a U.S. Customs and Border Protection portal created for that purpose. Bloomberg and CNBC reported that the administration was preparing to repay tens of billions of dollars, with interest, as those claims were processed. ### Which tariffs did the court actually knock out? Chief Justice John Roberts’ opinion said the question before the court was whether IEEPA authorizes the president to impose tariffs, and the answer was no. (supremecourt.gov) The syllabus says Trump had invoked IEEPA after declaring emergencies tied to drug trafficking and trade deficits, then imposed duties including 25% on most Canadian and Mexican imports, 10% on most Chinese imports, and at least 10% on imports from all trading partners under the reciprocal program. Tax Foundation said the ruling invalidated the IEEPA tariffs, including the administration’s “Liberation Day” tariffs, while leaving other trade tools such as Section 232 tariffs in place. (taxfoundation.org) That distinction matters because the court did not erase all Trump-era tariffs; it erased the ones tied to this specific emergency statute. ### How big is the refund exposure now? Customs official Brandon Lord said in a court filing that CBP had calculated expected refunds with interest totaling $35.46 billion on 8.3 million shipments as of May 11. CNBC reported that the filing covered the first large wave of validated claims, and Bloomberg described the broader pot of overturned duties as roughly $166 billion. (supremecourt.gov) Bloomberg reported in April that the refund portal was built to handle claims tied to about $166 billion in duties overturned by the Supreme Court. Fortune, in a commentary republished by Yahoo Finance, said companies including Walmart, Apple, Home Depot, General Motors, John Deere, FedEx and Costco were seeking refunds. (taxfoundation.org) The user-provided reporting also identified Cardinal Health and Walmart among companies pursuing repayment. ### Who actually paid these tariffs? CNBC reported that companies, not foreign governments, are the ones filing refund claims and receiving the first payments. (cnbc.com) Oshkosh said it had begun receiving refunds, while Basic Fun said the initial payment covered about 5% of its claim on early invoices. Trump said in a May 12 WABC interview that paying the money back was “crazy” and added, “In theory, you have to pay the tariffs back. We’ll fight that.” Tax Foundation said U.S. importers are legally responsible for paying tariffs on imported goods. That is why the refund process runs through import entries and customs records, not through foreign exporters or governments. (bloomberg.com) ### What is the $10 billion error in the court filings? A May 26 Daily Beast report, reflected in syndicated coverage, said a Trump administration court declaration revealed that CBP had overstated tariff refunds by at least $10 billion. The same report said the trade court is monitoring the refund program and that more than 4,000 consolidated refund payments remained pending because importers had not yet established digital payment capability. (cnbc.com) Because the underlying court declaration was not directly available in the search results I could open, that $10 billion figure should be treated as reported in secondary coverage unless confirmed from the filing itself. (taxfoundation.org) The broader point is independently supported: the refund system is being supervised through Court of International Trade filings, and the sums involved are already in the tens of billions. ### What happens next in the case and in the payment process? The Court of International Trade is the venue now overseeing implementation questions, including how refunds are processed and tracked. (newsbreak.com) Bloomberg reported on April 28 that the first payments were expected around May 11, and CNBC reported on May 12 that the first wave had started to reach importers’ bank accounts. CBP’s next updates in the trade court will show how many additional entries have been validated, how much interest is added, and whether disputed or delayed claims are resolved. Companies that paid IEEPA tariffs — including large retailers, manufacturers and health-care distributors named in recent filings and reporting — are still watching that process because the remaining refund total extends well beyond the $35.46 billion already calculated as of May 11.
