Mayors and presidents of groups of communes are elected by proportional representation with the highest average. Voting takes place on complete lists, without the addition or deletion of names, and without changing the order of presentation.
Lists of candidates are submitted to the departmental prefecture on a date set by order of the prefect taken after consulting the president of the general council. This order also sets the deadline for sending ballot papers to the departmental prefecture.
No one may be a candidate in different categories.
