Amend'ment, an alteration or change in a law or a proposal to change a law or to change a resolution already under discussion in a public meeting. When amendments are made in either house of Congress upon a bill which passed the other, the bill, as amended, must be sent back to the other house for concurrence. The Constitution of the United States contains a provision for its own amendment as follows:-- "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 1808 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." In parliamentary bodies a bill or resolution may be amended, and this amendment may be amended, but the amendment to the amendment cannot be amended.
