According to Article 89 of the Constitution of the
Fifth Republic, revisions to the constitution may be instigated by either deputies or senators (this is called "proposition de révision"), or by the
President of the Republic through proposals submitted by the
Prime Minister (this is called "projet de révision"). The normal procedure of constitutional revision is through national
referendum. However, in the case of "projet de révision", the President may turn to a more flexible and less demanding procedure. The constitution stipulates that
However, a Government Bill to amend the Constitution shall not be submitted to referendum where the President of the Republic decides to submit it to Parliament convened in Congress; the Government Bill to amend the Constitution shall then be approved only if it is passed by a three-fifths majority of the votes cast. The Bureau of the Congress shall be that of the National Assembly. The Congress traditionally takes place in Versailles. ==Address by the President of France==
