(a) Appointment.--If the parties to an agreement to arbitrate agree on a method for appointing an arbitrator, that method must be followed unless the method fails. If the parties have not agreed on a method, the agreed method fails or an arbitrator appointed fails or is unable to act and a successor has not been appointed, the court, on motion of a party to the arbitration proceeding, shall appoint the arbitrator. An arbitrator appointed by the court has all the powers of an arbitrator designated in the agreement to arbitrate or appointed under the agreed method.

(b) Neutral service.--An individual may not serve as an arbitrator required by an agreement to be neutral under the standards under which a judge would be required to disqualify himself or herself from participation in a proceeding under 207 Pa. Code Ch. 33 Canon 2 Rule 2.11 (relating to disqualification).
