TITLE XVIII. OF THE REVISION OF THE CONSTITUTION
Article 185
The initiative of the revision of the Constitution belongs, concurrently, to the President of the Republic and to the members of the Parliament.
No procedure for the revision may be engaged or pursued when it infringes the integrity of the territory.
The republican form, the secular character of the State, the number of mandates of the President of the Republic, as well as the rights enunciated at Titles I and II may not be made the object of revision.
Article 186
When it emanates from the President of the Republic, the bill of revision is submitted directly to referendum, after the opinion of conformity of the Constitutional Court.
When it emanates from the Parliament, the proposal of revision must be voted by two-thirds of the members of the two chambers of the Parliament meeting in Congress, after the opinion of conformity of the Constitutional Court.
In the two cases, the revision is only definitive after being approved by referendum.
Article 187
An organic law establishes the conditions for the revision of the Constitution.
