The regional prefect has a period of three months in which to grant or refuse approval.
The starting point for this period is set at the date of issue of the acknowledgement of receipt specifying the completeness of the application file submitted by the group.
If the regional prefect has not notified his response within the time limit set, the group is deemed to have been approved.
The withdrawal of approval, pronounced by the regional prefect, is notified by letter to the group and to all the administrations.
