Article V of the U.S. Constitution provides two methods of proposing amendments. First, Congress, with the approval of two-thirds of both houses, may propose amendments to the states for ratification, a procedure used for all 27 current amendments. Second, if the legislatures of two-thirds of the states apply, 34 at present, Congress "shall" call a convention for considering and proposing amendments. This alternative, known as an Article V Convention, has yet to be implemented. This report examines the Article V Convention, focusing on contemporary issues for Congress. CRS Report R42592, The Article V Convention for Proposing Constitutional Amendments: Historical Perspectives for Congress, examines the procedure's constitutional origins and history and provides an analysis of related state procedures.
