<h1>Fast-track review will decide whether the President can impose broad tariffs under IEEPA (50 U.S.C. §1701)</h1> The Supreme Court will fast-track review of whether the president can unilaterally impose broad tariffs under the International Emergency Economic Powers Act and other statutes after declaring national emergencies. Lower courts largely found the tariffs unlawful, though an appellate panel left them in place, and petitioners and respondents agreed to an accelerated schedule. Central legal questions include statutory limits on emergency tariff authority, separation of powers given Congress's constitutional tariff power, and whether past congressional acquiescence expands executive reach. The outcome could require Treasury refunds, affect ongoing trade negotiations and national-security measures, and determine the scope of presidential tariff authority going forward.
