Overview
- Oral arguments on Wednesday will review consolidated challenges to the “Liberation Day” program and country‑specific duties imposed under emergency declarations.
- Lower courts concluded the president lacked authority under IEEPA to impose sweeping, revenue‑raising tariffs but allowed the duties to remain in effect pending the Supreme Court’s ruling.
- Treasury Secretary Scott Bessent says he will attend to underscore the national‑security framing, while the president opted not to appear at the hearing.
- Businesses and states warn of tens of billions in potential refunds and major economic disruption; federal receipts include $195 billion in tariff revenue in fiscal 2025, with estimates indicating roughly half tied to IEEPA.
- The outcome may hinge on textual interpretation, the major‑questions doctrine, and deference in foreign affairs, and officials say other trade statutes such as Sections 232, 301, and 338 could be used if IEEPA tariffs are curtailed.
