In addition to the measures of isolation or separation from other detainees that he or she may order in accordance with the provisions of Articles D. 56-1 and D. 56-2, the magistrate responsible for the information file has the right to prescribe a temporary ban on communication by virtue of Article 145-4.
Under no circumstances does the ban on communication apply to counsel for the person under investigation, but it does prevent the detainee it concerns from being visited by or corresponding with any other person outside the prison administration.
