Supreme Court announces it will hear challenges to Trump’s tariffs on Nov. 5

The Supreme Court will hear arguments on Nov. 5 in the pair of challenges to President Donald Trump’s authority to impose tariffs under the International Emergency Economic Powers Act. The court on Thursday morning released an updated calendar for its November argument session that reflects the addition of the tariffs dispute, which the justices added to their docket for the 2025-26 term on Sept. 9.

The dispute over Trump’s tariffs is operating on a highly expedited schedule. The government will file its opening brief on Friday, just 10 days after the court announced that it had granted review; the challengers’ briefs will follow just over one month after that. Both sides had urged the court to act quickly. The Trump administration has argued that the ruling by a federal appeals court that the tariffs are unlawful “has disrupted highly impactful, sensitive, ongoing diplomatic trade negotiations,” while the challengers have pointed to the “severe economic hardships” caused by the tariffs.

To accommodate the addition of the tariffs dispute to the November argument calendar, the case that had initially been scheduled for Nov. 5 was moved to Nov. 4, and Hamm v. Smith, a death-penalty case that had originally been scheduled for Nov. 4, was taken off the November calendar. It presumably will be rescheduled at a later date.
