Supreme Court Extends Time, Sets Lineup for Nov. 5 Tariff Case

Overview

• The justices expanded oral arguments to 80 minutes on Nov. 5, allocating 40 minutes to the government and 20 minutes each to private-business plaintiffs and the coalition of states.
• Members of the Blackfeet Nation were denied a request to participate in the Supreme Court hearing, though their separate case remains pending elsewhere.
• Two challenges, Learning Resources, Inc. v. Trump and V.O.S. Selections, Inc. v. Trump, were consolidated, and parties filed briefs earlier this week.
• The Court will consider whether IEEPA authorizes the tariffs and whether such authority would be an unconstitutional delegation, after a 7–4 Federal Circuit decision found no clear IEEPA basis but stayed its ruling.
• Fiscal stakes are substantial, with Penn Wharton estimating $80.3 billion in revenue from January through July 2025 and the CBO projecting up to $4 trillion over a decade alongside higher consumer prices.
