The closing order may only be revoked by the court, of its own motion or at the request of the parties and after the opening of the hearings, if a serious cause has arisen since the order was made; the party’s choice of a person to assist or represent it after the closure does not, in itself, constitute a cause for revocation.
If an application to intervene voluntarily is filed after the close of the hearing, the closing order is revoked only if the court cannot rule on the case immediately.
