Article 144
The initiative of revision of the Constitution belongs concurrently to the President of the Republic and to one-fifth (1/5) at least of the deputies composing the National Assembly.
The bill or the proposal of revision is considered as adopted if it is voted with the majority of four-fifths (4/5) of the deputies composing the National Assembly.
In default this majority, the bill or proposal of revision adopted with the majority of two- thirds (2/3) of the deputies composing the National Assembly, is submitted to referendum.
The President of the Republic may submit to referendum any bill of constitutional law.
No procedure of revision may be engaged or pursued in a period of interim or of vacancy or when the integrity of the territory is infringed.
The Republican form and the secularity of the State may not be the object of a revision.
