If it is necessary to carry out technical or scientific findings or examinations, the public prosecutor or, with the latter’s authorisation, the officer or agent of the judicial police or, under their supervision, the investigation assistant, shall have recourse to any qualified persons.
The last four paragraphs of Article 60 shall apply.
The public prosecutor may, by means of general instructions issued pursuant to Article 39-3, authorise officers or agents of the judicial police or, under their supervision, investigation assistants to request any qualified persons in order to carry out medical or psychological examinations of the victim or to carry out medical examinations of the person suspected of having committed one of the offences mentioned in Article 706-47 or required pursuant to Article 706-115. The public prosecutor shall be notified of these instructions without delay. These general instructions are issued for a period not exceeding six months. They may be renewed.
No authorisation is required when the judicial police officer has recourse to a qualified person for the purposes of:
1° Comparing a genetic fingerprint obtained from a biological trace with the genetic fingerprint of a person against whom there are one or more plausible grounds for suspecting that he or she has committed one of the offences mentioned in Article 706-55, or to the comparison between several biological traces ;
2° To compare a fingerprint or palm print with the fingerprint or palm print of a person against whom there are one or more plausible grounds for suspecting that he or she has committed a crime or offence, or to compare several fingerprints or palm prints.
