On October 24, 2025, WLF urged the Supreme Court to affirm lower court decisions holding that the tariffs President Trump imposed under the International Emergency Economic Powers Act (IEEPA) are unlawful. As WLF’s amicus curiae brief makes clear, IEEPA gives the President no legal basis to impose tariffs, and the administration’s strained reading to the contrary violates the major questions canon. WLF also filed in this case at the certiorari stage and in the D.C. Circuit.
