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.
