509. In appeal, recourse may, in particular, be had to intervention, continuance of suit, change of attorney, recusation, disavowal and discontinuance, in the same circumstances as in first instance.
Incidental proceedings are raised by motion and the procedure is the same as in first instance, failing rules of practice to the contrary.
However, a motion to cease representing a party, the change of attorney, the disavowal and the discontinuance are within the competence of a judge. He may also hear a request for recusation in any case referred to him.
The court or as the case may be, the judge may, in connection with an incidental proceeding, permit the production of documents, receive affidavits, hear witnesses and even return the case to the court of first instance so that additional proof relating to the case may be made.
