Article V Convention for Proposing Constitutional Amendments: Historical Perspectives for Congress [July 10, 2012] [open pdf - 331KB]
"The Philadelphia Convention of 1787 provided two methods of proposing amendments to the U.S. Constitution. In the first, Congress, by two-thirds vote in both houses, proposes amendments to the states. If three-fourths of the states (38 at present) vote to ratify the amendment, it becomes part of the Constitution. Since 1789, Congress has proposed 33 amendments by this method, 27 of which have been adopted. In the second method, if the legislatures of two-thirds of the states (34 at present) apply, Congress must call a convention to consider and propose amendments, which must meet the same 38-state ratification requirement. This alternative, known as the Article V Convention, has not been implemented to date. Several times during the 20th century, organized groups promoted a convention that they hoped would propose amendments to the states, or to 'prod' Congress to propose amendments they favored. The most successful was the movement for direct election of Senators, which helped prod Congress to propose the 17th Amendment. The most recent, which promoted a convention to consider a balanced federal budget amendment, gained 32 applications, just two short of the constitutional threshold. […] Only the states can summon an Article V Convention, by application from their legislatures. Some of the issues concerning this process include procedures within the state legislatures; the scope and conditions of applications for a convention; steps in submitting applications to Congress; and the role of the state governors in the process."
