TITLE XVIII. OF THE REVISION OF THE CONSTITUTION
Article 152
The initiative of the revision of the Constitution belongs concurrently to the President of the Republic and to the Deputies.
To be taken into consideration, the bill or the proposal of revision is adopted by the National Assembly by the simple majority of its members. It does not become definitive until after having been approved by referendum.
Nevertheless, the bill of revision is not presented to referendum when the President of the Republic decides to submit it to the National Assembly alone. In this case, the bill of revision is approved by a majority of two-thirds of the members composing the National Assembly. It is the same for the proposal of revision that would have to obtain the approval of the President of the Republic.
Article 153
No procedure of revision may be engaged in [entreprise] in the case of occupation of a part or of the totality of the national territory, in the case of state of urgency or of state of siege.
Article 154
The republican form of the State, the principle of secularity [laïcité], the principle of the uniqueness [unicité] of the Sate, the principle of the separation and of the equilibrium of the powers, the political and syndical pluralism, [and] the number and the duration of the mandates of the President of the Republic[,] may not be made the object of a revision.
