TITLE VII. AMENDMENT AND INVIOLABILITY OF THE CONSTITUTION
CHAPTER I. AMENDMENT OF THE CONSTITUTION
The amendment of this Constitution may be decreed by the National Congress, in regular session, with two thirds of the votes of all its members. The decree shall specify for that purpose the article or articles that are to be amended, which must be ratified by the subsequent regular legislative session, by the same number of votes, in order to take effect.
The foregoing article, this article, the articles of the Constitution relating to the form of government, national territory, the presidential term, the prohibition from reelection to the presidency of the Republic, the citizen who has served as President under any title, and that referring to persons who may not be President of the Republic for the subsequent period may not be amended in any case.
CHAPTER II. THE INVIOLABILITY OF THE CONSTITUTION
This Constitution does not cease to be in effect nor does it cease to be in force by act of force or when it is allegedly repealed or amended by any means or procedure other than that which it itself provides. In these cases, every citizen, whether or not invested with authority, has the duty to cooperate in maintaining or reestablishing its effectiveness.
Persons responsible for the events specified in the first part of the foregoing paragraph, as well as the principal officials of governments that may subsequently be organized, shall be tried in accordance with this Constitution and the laws issued in conformity therewith, if they have not assisted in immediately reestablishing the rule of this Constitution and the authorities constituted in accordance therewith. The Congress may, by a vote of an absolute majority of its members, decree the forfeiture of all or part of the property of those same persons and of others who have enriched themselves by supplanting the sovereignty of the people or by usurping the public powers, to compensate the Republic for any losses incurred on account of them.
