Leonard Shambon examines whether the International Emergency Economic Powers Act (IEEPA) grants the President broad authority to impose tariffs, with a focus on congressional intent and legislative history as interpreted through the Supreme Court’s major questions doctrine. Mr. Shambon argues that both the content and procedural handling of the 1977 bill that became IEEPA show Congress never intended to delegate sweeping tariff powers to the President, as evidenced by the lack of involvement from committees with explicit tariff jurisdiction and the absence of any mention of tariffs in legislative documents and discussions.
