Supreme Court Takes Up Explosive Case Testing Trump’s Emergency Powers on Tariffs

Washington, D.C. – The Supreme Court will hear arguments in a consolidated case challenging the Trump administration’s use of the International Emergency Economic Powers Act (IEEPA) to impose tariffs, with potential refunds of tens of billions in collected duties hanging in the balance.

The cases, Learning Resources v. Trump and Trump v. V.O.S. Selections, Inc., brought by small businesses, argue the president exceeded his authority under IEEPA, a law typically used for sanctions, not broad tariffs.

Lower courts ruled against the administration, prompting an appeal, as the Tax Foundation estimates the tariffs have generated $88 billion in 2025 revenue but could reduce GDP by 0.4% and cost 428,000 jobs over a decade.

The Cases and Legal Challenge

The consolidated cases involve small businesses like Learning Resources, a toy manufacturer, and V.O.S. Selections, an importer, who challenged the tariffs’ constitutionality, claiming IEEPA, enacted in 1977, grants emergency powers for sanctions, not ongoing trade policy, per court filings.

The Trump administration invoked IEEPA in 2019 for China tariffs and expanded it in 2025 for $300 billion in goods from China, Mexico, and Canada, per U.S. Customs and Border Protection. A federal district court and appeals court rejected the administration’s argument, ruling the president exceeded legal authority, per the U.S. Court of Appeals for the Federal Circuit.

The Tax Foundation estimates the tariffs will raise $1.8 trillion in revenue from 2025 to 2034 but reduce GDP by 0.4% and employment by 428,000 jobs, excluding retaliation, per their October 2025 report. It also projects an average $1,000 tax increase per household in 2025 and $1,300 annually thereafter, as importers pass costs to consumers, per BLS consumer price index data.

Trump’s Defense and Economic Impact

Trump, in a November 3, Fox News Sunday Morning Futures appearance, called the case “vital to the interests of our country. We’re the wealthiest country there is. If we don’t [win], we’ll be struggling for years to come.”

The administration argues IEEPA empowers the president to address unfair trade deals and reshore manufacturing.

Critics, including Dr. Wayne Winegarden of the Pacific Research Institute, told FOX Business, “The economic consequences of the IEEPA tariffs are troubling. Not only are the consequences stagflationary, but they also create uncertainty detrimental to future economic activity.” Winegarden warned it “usurps taxation powers from Congress and creates a gigantic loophole for future presidents to impose tariffs for dubious justifications.”

The tariffs have contributed to inflation, with CPI rising 0.3% in September, driven by 2.5% higher import prices, per BLS. Hiring slowed in October, with 142,000 jobs added versus 180,000 expected, per ADP data.

Potential Refunds and Business Preparation

Dallas Dolen, U.S. TMT industry leader at PwC, said that $89 billion in tariff revenue has been collected in 2025, expected to reach $108 billion by October’s end, with refunds possible if the Court rules against the administration.

“If the Supreme Court ultimately rules that the tariffs were unlawful, the full amount could potentially be subject to refund, depending on how the Court structures its decision,” Dolen said. Businesses face a “complicated and time-consuming process” for refunds, with many modeling scenarios and reviewing customs data.

The tariff case highlights escalating trade tensions. Trump’s October 60% tariff on Chinese EVs has boosted U.S. EV prices 15%. A federal judge’s November 1, ruling upholding Trump’s steel tariffs has sparked protests in Ohio. The Commerce Department’s September investigation into alleged dumping by Mexican automakers has drawn retaliation threats.

A ruling against the administration could refund $88 billion, but processing refunds may take years, with IRS overwhelmed by 2025 tax season delays. If upheld, tariffs could expand to $500 billion in imports, deepening inflation.
