At the request of one fifth of its members, the departmental council deliberates on the creation of an information and assessment mission, tasked with gathering information on an issue of departmental interest or assessing a departmental public service. The same departmental councillor may not take part in such a request more than once a year.
No mission may be created from 1 January of the calendar year preceding the year of the general renewal of the departmental councils.
The rules of procedure set out the rules for submitting and examining the request to set up the mission, its operating procedures, the procedures for its composition in compliance with the principle of proportional representation, the duration of the mission, which may not exceed six months from the date of the deliberation setting it up, as well as the conditions under which it submits its report to the members of the departmental council.
