Overview

• Justice Department filings ask the court to decide by Sept. 10 whether to hear the case and to hold arguments in early November, a timetable the challengers support.
• The Federal Circuit’s decision is stayed through Oct. 14, so the challenged tariffs remain in force while the Supreme Court weighs next steps.
• The case covers broad 'reciprocal' tariffs with a 10% baseline and higher country-specific rates and a separate 25% duty on some imports from Canada, China and Mexico tied to fentanyl, while tariffs under other statutes are not at issue.
• Treasury Secretary Scott Bessent warned that prolonged uncertainty could derail trade talks and might require massive refunds, with a worst‑case estimate of $750 billion to $1 trillion collected by mid‑2026.
• Plaintiffs include five small import businesses represented by the Liberty Justice Center and 12 states, who argue the tariffs are unlawful and are inflicting serious economic harm.
