632. Arbitrators conduct the arbitration according to the procedure they determine; they are required, however, to see that the adversarial principle and the principle of proportionality are observed.
Arbitrators have all the necessary powers to exercise their jurisdiction, including the power to administer oaths, the power to appoint an expert and the power to rule on their own jurisdiction.
If an arbitrator rules on the arbitrator’s own jurisdiction, a party, within 30 days after being advised of the decision, may ask the court to rule on the matter. A decision of the court recognizing the jurisdiction of the arbitrator cannot be appealed.
For so long as the court has not made its ruling, the arbitrator may continue the arbitration proceedings and make an award.
