Learning Resources, Inc. v. Trump, No. 24-1287 Trump v. V.O.S. Selections, No. 25-250 – Decided February 20, 2026~~Today, the Supreme Court held 6-3 that the International Emergency Economic Powers Act does not grant the President the power to impose tariffs.~~“Based on two words separated by 16 others in Section 1702(a)(1)(B) of IEEPA—’regulate’ and ‘importation’—the President asserts the independent power to impose tariffs on imports from any country, of any product, at any rate, for any amount of time. Those words cannot bear such weight.”~~Chief Justice Roberts, writing for the Court~~Background:~~The International Emergency Economic Powers Act (IEEPA) grants the President the power, upon declaring a national emergency, to “regulate . . . importation or exportation of . . . any property in which any foreign country or a national thereof has any interest.” 50 U.S.C. § 1702(a)(1)(B). From February to April 2025, President Trump invoked IEEPA and issued five executive orders imposing tariffs of up to 125% based on declared emergencies of fentanyl trafficking and trade imbalances. In subsequent months, the President amended and altered those tariffs.~~Some plaintiffs challenged the tariffs in the U.S. District Court for the District of Columbia, while others challenged the tariffs in the U.S. Court of International Trade. Both courts ruled against President Trump’s tariffs. The District Court granted plaintiffs’ motion for a preliminary injunction on the grounds that IEEPA does not grant the President the authority to impose any tariffs. Before the D.C. Circuit ruled on the appeal of the preliminary injunction, the Supreme Court granted certiorari before judgment. The Court of International Trade granted summary judgment to plaintiffs, holding that IEEPA does not authorize tariffs based on trade imbalances because they are governed by a different statute. On appeal, the en banc U.S. Court of Appeals for the Federal Circuit affirmed 7-4, holding that, while IEEPA may authorize some tariffs, it does not authorize tariffs as broad or large as the challenged tariffs.~~Issue:~~Are President Trump’s emergency tariffs authorized by IEEPA? If so, does IEEPA unconstitutionally delegate legislative authority to the President?~~Court’s Holding:~~No. IEEPA does not grant the President any authority to impose tariffs.~~What It Means:~~The Court’s opinion is available here.~~Gibson Dunn’s lawyers are available to assist in addressing any questions you may have regarding developments at the Supreme Court.
