In each of the departmental commissions for inter-communal cooperation provided for in article L. 5211-42 the number of members is set at 40.
This number is increased by one additional seat:
a) From a threshold of 600,000 inhabitants in the department, then per tranche of 300,000 inhabitants;
b) Per commune with more than 100,000 inhabitants in the department;
c) From a threshold of 400 communes in the department, then per tranche of 100 communes;
d) Per public inter-municipal cooperation body with its own tax status with more than 50,000 inhabitants in the department;
e) From a threshold of twenty-five public inter-municipal cooperation bodies with their own tax status in the department, then per tranche of ten bodies.
A prefectoral decree establishes in each department the total number of members of the commission as well as the number of seats allocated to each category of territorial authority or public establishment by applying the distribution rules set out in article L. 5211-43, rounded to the nearest whole number if necessary.
