On pain of nullity, the authorisations provided for in articles 706-89 to 706-91 are given for specific searches and are the subject of a written order, specifying the nature of the offence for which proof is sought and the address of the premises in which the visits, searches and seizures may be carried out; this order, which may not be appealed, shall be reasoned by reference to the factual and legal elements justifying that these operations are necessary and that they cannot be carried out during the hours provided for in Article 59. The operations are carried out under the supervision of the magistrate who authorised them, who may visit the premises to ensure compliance with the legal provisions. The magistrate who authorised them is informed as soon as possible by the public prosecutor or the judicial police officer of the acts carried out pursuant to articles 706-89 to 706-91.
In the cases provided for in the second paragraph of article 706-90 and in 1° to 4° of article 706-91, the order shall also include a statement of the considerations of law and fact that form the basis of this decision by reference only to the conditions provided for by these paragraphs.
For the application of the provisions of articles 706-89 and 706-90, the liberty and custody judge of the judicial court of which the public prosecutor is leading the investigation shall have jurisdiction, regardless of the court within whose jurisdiction the search is to take place. The liberty and custody judge may then visit the premises wherever they are located in France. The public prosecutor may also refer the matter to the liberties and detention judge of the judicial court within whose jurisdiction the search is to take place, via the public prosecutor of that court.
