The examining magistrate may request by letter rogatory any judge of his court, any examining magistrate or any officer of the judicial police, who shall in this case notify the public prosecutor, to carry out the acts of information that he considers necessary in the places where each of them has territorial jurisdiction.
The letter rogatory shall indicate the nature of the offence, which is the subject of the proceedings. It shall be dated and signed by the magistrate issuing it and stamped with his seal.
It may only prescribe investigative acts directly related to the repression of the offence being prosecuted.
The investigating magistrate shall set the time limit within which the letter rogatory must be returned to him together with the reports drawn up for its execution by the judicial police officer. Failing this, the letter rogatory and the reports must be sent to him within eight days of the end of the operations carried out under it.
