Persons detained in the centres come under the jurisdiction of a vice-president responsible for the enforcement of sentences of one of the judicial courts of the court of appeal, appointed by the first president of this court.
This magistrate is responsible for monitoring, for each person detained, the main procedures for implementing secure detention and the smooth running of the measure.
He may have any examinations, hearings, investigations, expert reports, requisitions or verifications carried out throughout France that are useful for the exercise of his or her powers.
It visits the centres under its jurisdiction at least once a month and checks with each person detained the conditions in which they are being held.
The first president of the court of appeal may appoint one or more substitute judges from among the vice-presidents responsible for the enforcement of sentences in the judicial courts within its jurisdiction.
