U.S. Supreme Court Shakes Up Trump Tariff Tactics
On February 20, 2026, the U.S. Supreme Court issued its much-anticipated ruling in the Learning Resources case, concluding that the tariffs imposed by the Trump administration since February 2025 under the International Emergency Economic Powers Act (IEEPA) were unauthorized. The Court’s landmark 6-3 decision produced seven separate opinions with Chief Justice John Roberts and Justices Sonia Sotomayor, Elena Kagan, Neil Gorsuch, Amy Coney Barrett, and Ketanji Brown Jackson in the majority, holding that “the power to unilaterally impose tariffs of unlimited amount, duration, and scope” required “clear congressional authorization.” This decision affirmed earlier Federal Circuit and Court of International Trade (CIT) rulings rejecting the President’s authority to impose both the “fentanyl-related” (or “trafficking”) tariffs applied to products of China, Canada, and Mexico and the “reciprocal” tariffs applied to products of U.S. trading partners since “Liberation Day” back in April 2025. Notably, the Court’s opinion did not address the availability of or timing for any refunds owed to importers who have already paid the fentanyl-related and reciprocal tariffs.

On September 29, 2025, BIS released an interim final rule (the September 29 IFR) announcing that BIS will adopt a similar approach to that currently used by the Treasury Department’s Office of Foreign Assets Control for its Specially Designated Nationals List restrictions and expand the scope of the Entity List, Military End User (MEU) List, and Section 744.8 restrictions to non-U.S. entities owned, directly or indirectly, and individually or in the aggregate, 50 percent or more by another party enumerated on an applicable list (such parties, a Foreign Affiliate). U.S. entities owned by a listed entity are not subject to the new restrictions.

Federal Circuit Affirms Tariff Illegality but Defers Action to Remove Tariffs Pending Appeal
On August 29, 2025, the U.S. Court of Appeals for the Federal Circuit (the Court of Appeals) affirmed in a 7-4 ruling that although the International Emergency Economic Powers Act (IEEPA) could give President Trump the authority in some cases to impose tariffs, it did not give the administration the authority to impose the reciprocal and fentanyl-related tariffs that have been in place since earlier this year. In a separate Order, the Court of Appeals withheld issuance of its mandate to allow for further appeal to the U.S. Supreme Court, which the administration has already petitioned to take the case, requested to expedite, and received the acquiescence of the private plaintiffs and the state plaintiffs to do so. A ruling on the petition for certiorari is expected soon. Thus, importers will continue to be required to pay these tariffs until the Supreme Court directs otherwise.
