This issue may take place ex officio or, in accordance with the provisions of articles 77-2,82-1,315,388-5 and 459, at the request of the suspected or accused person, the victim or the civil party. The judicial authorities referred to in the first paragraph may only issue an investigation order for the execution of measures that they themselves are empowered to order or execute in accordance with the provisions of this Code. If the investigation decision concerns an act requiring the prior authorisation of the juge des libertés et de la détention, it may only be issued after the authorisation of the latter. The authorisations of the juge des libertés et de la détention provided for in articles 76,230-33,230-34 and 706-92 may not mention the address of the private place in which a search may be carried out or in which a geolocation device may be installed or removed, if this address is not known when the investigation decision is issued, provided that the identity of the person at whose premises these operations may be carried out is mentioned. The first decision of the liberty and custody judge provided for in 1° of article 230-33 allowing the geolocation decided for fifteen days or eight days by the public prosecutor to continue for one month may be issued before the investigation decision is issued. When, during the execution of a European investigation order, the magistrate travels to the territory of the executing State pursuant to the fifth paragraph of Article 41 or Article 93-1, he may issue an investigation decision in addition to the previous decision.
