"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." Article 5 of the U S Constitution
Article 5 defines the process for amending the Constitution.
The U S Constitution does not automatically change with the times. It is not a living, breathing document because we can exercise common sense and change its meaning. It is a living, breathing document because we can change it any time we want according to Article 5. It is a written document that means what it says.
Most importantly, 'we the people' can use this process without Congressional approval. We don't need permission.
Neither federal, state, nor local laws overwrite the U S Constitution.
