Constitution de partie civile may take place at any time during the investigation.
It may be contested by the public prosecutor or by a party.
In the event of a challenge, or if he declares the civil party constitution inadmissible, the investigating judge shall rule, after communication of the file to the public prosecutor, by reasoned order, which the interested party may appeal.
If a civil party’s claim is contested after the notice of the end of the investigation provided for in Article 175, it may not be examined either by the examining magistrate or, in the event of an appeal, by the investigating chamber, without prejudice to its examination, in the event of referral, by the trial court.
