1024. A member may, by motion, apply to the court to have himself or another member substituted for the representative.
The court may substitute the applicant or another member consenting thereto for the representative if it is of opinion that the latter is no longer in a position to represent the members adequately.
The substituted representative accepts the trial at the stage it has then reached; he may, with the authorization of the court, refuse to ratify the proceedings already had if they have caused an irreparable prejudice to the members. He cannot be bound to pay the costs and other expenses for proceedings prior to the substitution, unless the court orders otherwise.
