... shall call a Convention for proposing Amendments, ...That is an AMENDING Convention, furthermore limited to PROPOSING such amendments then SUBJECT to:
which, in either Case, shall be valid to all Intents and Purposes, as part of this Constitution, when ratified by the Legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress;NO chance, NONE of a ROGUE convention. Try reading the Constitution once in a while.
So, a CONVENTION for proposing amendments to the CONSTITUTION is not a “constitutional convention??”
I guess that English must be your 3rd or 4th language, da?
