<h1>Final decision will determine if IEEPA allows president to impose broad countrywide tariffs or limits executive power</h1> A group of small businesses challenged presidential tariffs imposed under the International Emergency Economic Powers Act (IEEPA), arguing Congress, not the president, has primary tariff authority and that IEEPA does not authorize blanket countrywide tariffs. Two federal courts and the Court of International Trade have ruled the statute does not confer that power. The Supreme Court will decide whether IEEPA permits broad emergency tariff actions, a decision that could either reaffirm statutory limits on executive emergency powers or endorse expanded presidential authority; a ruling against the administration could prompt economic fallout and efforts to pursue similar measures under other statutes.
