Challenge of arbitrators.
Section 11
SEC. 11. Challenge of arbitrators.—The arbitrators may be challenged only for the reasons mentioned in the preceding section which may have arisen after the arbitration agreement or were unknown at the time of arbitration. The challenge shall be made before them. If they do not yield to the challenge, the challenging party may renew the challenge before the Court of First Instance of the province or city in which the challenged arbitrator, or, any of them, if there be more than one, resides. While the challenging incident is discussed before the court, the hearing on arbitration shall be suspended, and it shall be continued immediately after the court has delivered an order on the challenging incident.
