Where different rules govern the administrative control of communes according to the size of their population, the population of all the communes forming the public establishment of inter-communal cooperation is taken into account to determine the rules that should be applied.
In cases where the public establishment for inter-municipal cooperation extends over several départements, the administrative control referred to in article L. 5211-4 is exercised by the prefect of the department to which the commune with the headquarters of the public establishment of inter-communal cooperation belongs.
