A concurrent resolution expressing the sense of Congress that the proposed "joint interpretation" of Annex 14-C of the United States-Mexico-Canada Agreement prepared by United States Trade Representative Katherine Tai is of no legal effect with respect to the United States or any United States person unless it is approved by Congress.

This bill (SCONRES 5) states that any proposed "joint interpretation" of a specific USMCA provision (Annex 14-C) by the U.S. Trade Representative cannot have legal effect for U.S. persons unless Congress approves it. It directly affects U.S. businesses and investors with claims under Annex 14-C, which protects investments made under NAFTA in Canada or Mexico. The resolution requires Congress to formally approve such interpretations before they can be used in legal proceedings, and prohibits federal agencies from invoking unapproved interpretations. It asserts Congress's constitutional authority over trade agreements, emphasizing that executive branch actions cannot bind the U.S. without congressional consent.
