Part A. Election of the President of the Republic

Article 73  Election of the President
One month at least and two months at most before the expiration of the term of office of the President of the Republic, the Chamber is summoned by its President to elect the newPresident of the Republic.  However, should it not be summoned for this purpose, the Chamber meets of its own accord on the tenth day preceding the expiration of the President's term of office.
 
Article 74  Vacancy of Presidency
Should the Presidency become vacant through the death or resignation of the President or for any other cause, the Chamber meets immediately and by virtue of the law to elect a successor.  If the Chamber happens to be dissolved at the time the vacancy occurs, the electoral bodies are convened without delay and, as soon as the elections have taken place, the Chamber meets by virtue of the law.
 
Article 75
The Chamber meeting to elect the President of the Republic is considered an electoral body and not a legislative assembly.  It must proceed immediately, without discussion or any other act, to elect the Head of the State.
 
                                 Part B. Amending the Constitution

Article 76  Proposal
The constitution may be revised upon the proposal of the President of the Republic.  In such a case the Government submits a draft law to the Chamber of Deputies.
 
Article 77  Request
The constitution may also be revised upon the request of the Chamber of Deputies.  In this case the following procedures are to be observed:
During an ordinary session and at the request of at least ten of its members, the Chamber of Deputies may recommend, by a majority of two thirds of the total members lawfully composing the Chamber, the revision of the constitution.

However, the articles and the questions referred to in the recommendation must be clearly defined and specified.  The President of the Chamber then transmits the recommendation to the Government requesting it to prepare a draft law relating thereto.  If the Government approves the recommendation of the Chamber by a majority of two thirds, it must prepare the draft amendment and submit it to the Chamber within four months; it it does not agree, it shall return the Decision to the Chamber for reconsideration.  If the Chamber insists upon the necessity of the amendment by a majority of three fourths of the total members lawfully composing the Chamber, the President of the Republic has then either to accede to the Chamber's recommendation or to ask the Council of Ministers to dissolve the Chamber and to hold new elections within three months.  If the new Chamber insists on the necessity of amending the constitution, the Government must yield and submit the draft amendment within four months.
 
Article 78  Priority
When a draft law dealing with a constitutional amendment is submitted to the Chamber, it must confine itself to its discussion before any other work until a final vote is taken.  It may discuss and vote only on articles and questions clearly enumerated and defined in the draft submitted to it.
 
Article 79  Majority, Promulgation
(1) When a draft law dealing with a constitutional amendment is submitted to the Chamber, it cannot discuss it or vote upon it except when a majority of two thirds of the members lawfully composing the Chamber are present.  Voting is by the same majority.
(2) The President of the Republic is required to promulgate the law of the constitutional amendment under the same conditions and in the same form as ordinary laws. He has the right, within the period established for the promulgation, to ask the Chamber to reconsider the draft, after consultation with the council of Ministers, in which case the vote is by a majority of two thirds.
