Okla. Stat. tit. 85A, § 85A-311: Method of appointing arbitrator

A. If the parties to an arbitration agreement agree on a method

for appointing an arbitrator, that method shall 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 Commission, on

motion of a party to the arbitration proceeding, shall appoint the

arbitrator. An arbitrator appointed by the Commission has all the

powers of an arbitrator designated by the arbitration agreement.

B. An individual who has a known, direct, and material interest

in the outcome of the arbitration proceeding, or a known, existing,

and substantial relationship with a party to the arbitration

proceeding, may not serve as an arbitrator unless agreed to in

writing by the parties.
