Overview

• Justice Department filings seek expedited review with oral arguments as soon as early November, and the tariff challengers do not oppose the fast schedule.
• A 7–4 Federal Circuit ruling said most IEEPA-based tariffs are unlawful, but the court stayed its decision through Oct. 14, leaving the duties in place for now.
• Trump warned the U.S. might have to unwind recent trade deals with the EU, Japan and South Korea if the Supreme Court upholds the lower-court ruling.
• U.S. Customs and Border Protection reports $65.8 billion collected from IEEPA tariffs as of Aug. 25, and experts say refund pathways remain uncertain if those duties are struck down.
• Officials signal potential fallback options under other statutes, including new Section 232 investigations and the rarely used Smoot-Hawley Section 338, with sector-specific tariffs not part of this case.
