TITLE XVII. OF THE INTERNATIONAL TREATIES AND AGREEMENTS
Article 149
The President of the Republic negotiates and ratifies the international engagements.
The peace treaties, the treaties of commerce, the treaties or agreements relative to the international organization, those that engage the finance of the State, those that modify the provisions of a legislative nature, those that are relative to the status [l’état] of persons, those that include cession, exchange or adjunction of territory, may only be ratified or approved by a law.
No cession, no exchange, no adjunction of territory may take place without the consent by way [voie] of referendum of the concerned populations.
Article 150
If the Constitutional Court referred to [the matter] by the President of the Republic or by a Deputy, has declared that an international engagement contains a clause contrary to the Constitution, the authorization to ratify it or to approve it may only intervene after the revision of the Constitution.
A law authorizing the ratification or the approval of an international engagement may not be promulgated and enter into force when it has been declared nonconforming to the Constitution.
Article 151
The treaties or agreements regularly approved or ratified have, from their publication, a authority superior to that of the laws, under reserve of reciprocity.
