The hearing or confrontation is conducted under the direction of the officer or agent of the judicial police who may at any time, in the event of difficulty, put an end to it and immediately notify the public prosecutor who, if necessary, informs the President of the Bar so that another lawyer can be appointed.
At the end of each hearing or confrontation in which he or she is present, the lawyer may ask questions. The officer or agent of the judicial police may object to the questions only if they are likely to interfere with the proper conduct of the investigation. This refusal is noted in the record.
At the end of each interview with the person in police custody and each hearing or confrontation in which he or she has been present, the lawyer may submit written observations in which he or she may record the questions refused pursuant to the second paragraph. These will be attached to the proceedings. The lawyer may send his observations, or a copy thereof, to the public prosecutor during the period of police custody.
