An Arbitrator or Commissioner disqualified under subsection (b) may disclose on the record the basis of the disqualification and may ask the parties and their lawyers to consider, out of the presence of the Arbitrator or Commissioner, whether to waive disqualification. If, following disclosure of any basis for disqualification other than personal bias or prejudice concerning a party, the parties and attorneys, without participation by the Arbitrator or Commissioner, all agree in writing that the Arbitrator or Commissioner should not be disqualified, and the Arbitrator or Commissioner is then willing to participate, the Arbitrator or Commissioner may participate in the proceeding. The agreement signed by all parties and all attorneys shall be made a part of the record of the proceeding.
When a Commissioner withdraws from a case, it shall be the duty of the Commissioner to notify the Commission, whose function it shall be to transfer the case to a Commissioner, representative of the same statutorily designated class, sitting on a panel other than that on which the withdrawing Commissioner sits.
