This concurrent resolution declares that a proposed "joint interpretation" of Annex 14-C of the United States-Mexico-Canada Agreement (USMCA), prepared by United States Trade Representative Katherine Tai, holds no legal effect for the United States or its citizens unless explicitly approved by Congress. Annex 14-C is crucial as it provides recourse for United States persons who have made investments in Canada or Mexico, protecting them from arbitrary treatment or expropriation. Congress is concerned that the proposed interpretation could significantly limit and curtail these established rights for U.S. investors. The resolution firmly asserts Congress's constitutional authority over international trade, emphasizing that the executive branch lacks the power to enter into binding trade agreements or interpretations without Congressional consent. It also criticizes Ambassador Tai for failing to consult appropriately with Congress regarding this proposed interpretation, including by implementing unreasonable procedures that hindered members from reviewing its text. Therefore, no U.S. agency, including the Office of the United States Trade Representative or the Department of State, can invoke this "joint interpretation" in any legal proceeding or claim it has legal consequence until Congress formally approves it.
