When investigating or ascertaining an infringement or failure to comply with this book, the officers mentioned in Article L. 450-1 are authorised to identify the person they are controlling. If the person refuses or is unable to prove his or her identity, they shall immediately report this to any territorially competent judicial police officer, who may then carry out an identity check under the conditions set out in article 78-3 of the Code of Criminal Procedure. In this case, the period provided for in the third paragraph of the same article 78-3 shall run from the time of the identity check.
They may have recourse to any qualified person designated by the administrative authority to which they report. This person may accompany them during their inspections and take cognisance of any document or item necessary for the performance of their mission or expertise. This person may not carry out any criminal or administrative police procedure. It may not use the information it acquires in this way to implement any control powers it may have by virtue of other legislative or regulatory provisions. It may not, under the penalties provided for in article 226-13 of the Penal Code, divulge information of which it has become aware in this context.
