A commune may join a syndicate for only some of the competences exercised by the syndicate.
In this case, the decision to set up the syndicate or an amending decision determines the list of communes that are members of the syndicate, the list of competences that the syndicate may exercise and the conditions under which each member commune transfers to the syndicate all or part of the competences that the syndicate is entitled to exercise. The syndicate exercises each of its competences within the limits of the territory of the municipalities that have delegated that competence to it.
Each commune is obliged to bear, under the conditions laid down by the decision to set it up, the expenditure corresponding to the competences it has transferred to the syndicate as well as a share of the general administration expenditure.
As an exception to the provisions of the first paragraph of article L. 5211-1, the following rules apply:
1° All delegates take part in the vote on matters of common interest to all the communes and in particular for the election of the chairman and the members of the bureau, the vote on the budget, the approval of the administrative account and decisions relating to changes to the initial conditions of composition, operation and duration of the syndicate ; otherwise, only the delegates representing the communes concerned by the matter under discussion take part in the vote;
2° The chairman takes part in all votes except where articles L. 2121-14 and L. 2131-11;
3° In order to take account of the competences transferred by each commune to the syndicate, the decision to set up the syndicate may lay down specific rules for the representation of each commune.
The syndicate committee may set up commissions to study and prepare its decisions for the exercise of one or more competencies.
