Subject to the provisions of articles L. 3112-1 and L. 3112-2 concerning the boundaries of the départements, decisions relating to the modification of the territorial boundaries of the communes and the fixing or transfer of chief towns resulting or not from this modification are pronounced by order of the representative of the State in the département.
However, a decree in the Council of State, on the proposal of the Minister of the Interior, is required when the proposed territorial modification has the effect of affecting the cantonal boundaries.
