<22>Article Five of the United States Constitution
describes the process whereby the Constitution may be altered. Altering the Constitution consists of proposing an amendment and subsequent ratification.
Amendments may be proposed by either two-thirds of both houses of the United States Congress or by a national convention. This convention can be assembled at the request of the legislatures of at least two-thirds of the several states. To become part of the Constitution, amendments must then be ratified either by approval of the legislatures of three-fourths of the states or ratifying conventions held in three-fourths of the states. Congress has discretion as to which method of ratification should be used.
“ 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, 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; Provided that no Amendment which may be made prior to the Year One thousand eight hundred and eight shall in any Manner affect the first and fourth Clauses in the Ninth Section of the first Article; and that no State, without its Consent, shall be deprived of its equal Suffrage in the Senate.
