The closure order may only be revoked if a serious cause has come to light since it was made; the constitution of a lawyer subsequent to the closure does not, in itself, constitute a cause for revocation.
If an application for voluntary intervention is made after the closure of the investigation, the closure order is revoked only if the court cannot immediately rule on the whole.
The closing order may be revoked, of its own motion or at the request of the parties, either by reasoned order of the pre-trial judge or, after the opening of the hearings, by decision of the court.
The closing order may also be revoked, after obtaining the parties’ opinion, in order to allow the Pre-Trial Judge, in accordance with Article 785, to decide to summon the parties to a friendly settlement hearing in accordance with the procedures set out in Articles 774-1 to 774-4.
