Article V Convention
The United States Constitution:Article V states that:
|“||The Congress, whenever two thirds of both houses shall deem it necessary, shall propose amendments to this Constitution, or, on the application of the legislatures of two thirds of the several states, shall call a convention for proposing amendments ....||”|
Notice that it is only Congress which does the "call" for an Article V Convention, while the states can only apply for Congress to convene it.
An attempt was made to insert a call for Article V Convention into the 2016 Republican Party platform, but the proposal was rejected by an overwhelming vote of the delegates on the platform committee.
