Investigators and auditors may summon and interview any person likely to provide them with information. They shall present their personal mission order drawn up by the General Secretary in response to any request made in the course of their investigations.
The summons shall be sent to the person concerned by registered letter with acknowledgement of receipt or delivered by hand against a receipt or by a bailiff’s deed or by any other means that ensures receipt, at least eight days before the date of the summons. It shall refer to the personal mission order of the investigator or inspector. It reminds the person summoned that he or she is entitled to be assisted by counsel of his or her choice, pursuant to article L. 621-11.
When the investigators and inspectors wish to hear the person concerned by videoconference or audioconference, the summons sent under the conditions provided for in the previous paragraph must mention this, specify that the conference will be recorded and request the express agreement of the person concerned.
Investigators and inspectors may take explanations on the spot, on the basis of the second paragraph of article L. 621-10 or article L. 621-12, provided that the person being heard has been expressly informed of the right to be assisted by counsel of his or her choice and has expressly waived the time limit provided for in the event of a summons.
