The President negotiates and ratifies treaties (Article 114 of the Constitution). He or she is kept informed of any negotiations that might lead to the conclusion of an international agreement not subject to ratification. Peace treaties and commercial treaties, treaties or agreements related to international organisations, treaties involving the finances of the state, treaties relating to the condition of individuals, treaties involving surrender, exchange or addition of territory may not be approved or ratified except by law. Treaties or agreements regularly ratified or approved have, on publication, an authority superior to that of state laws, provided such treaties or agreements have been ratified or approved by the other contracting party.
