Trump Says He Won’t Attend Supreme Court Hearing on Tariffs as Justices Take Up IEEPA Case

The justices will decide whether emergency powers cover sweeping import taxes, with implications for presidential authority as well as tens of billions in disputed duties.

Overview

  • Oral arguments on November 5 will test whether the International Emergency Economic Powers Act authorizes President Trump’s broad “Liberation Day” tariffs.
  • The duties remain in force during the case, even after two lower courts—including a 7–4 Federal Circuit ruling—found the IEEPA tariffs unlawful.
  • Small businesses and a coalition of 12 states brought the challenges, arguing the levies burden firms and consumers and intrude on Congress’s Article I tariff power.
  • U.S. Customs data show nearly $90 billion had been collected under the disputed tariffs by late September, and an adverse ruling could trigger complex refund claims.
  • Rates have reached up to 50% on key partners and as high as 145% on China, with some countries striking deals as the administration defends the tariffs as vital to national security and leverage in negotiations.
