The Supreme Court's Decision on Trump Tariffs Will Have Lasting Impact on U.S. Economic Statecraft

Atlantic Council
Stephanie L. Connor

International Trade attorney Stephanie Connor wrote an article for the Atlantic Council analyzing the implications of the U.S. Supreme Court's decision to hear the Trump Administration's appeal of lower court rulings invalidating its tariffs imposed under the International Emergency Economic Powers Act (IEEPA). The U.S. Court of Appeals for the Federal Circuit affirmed the U.S. Court of Federal Claims' conclusion that IEEPA does not grant the president the "unbounded authority" necessary to impose sweeping tariffs and that power is instead reserved for Congress. Though the measures remain in place for now, the Supreme Court's decision could shape U.S. economic and trade policy for years to come. In her article, Ms. Connor breaks down the key question in the case – how much deference to give the president in matters of foreign affairs and national security – and elaborates on how the outcome could affect the country's standing in an increasingly competitive global economy.
