(b) A Board member, Board agent, conciliator, mediator, or other PERB officer, employee, or contractor shall recuse themselves from a case or proceeding if any one of the following circumstances exists:

(c) If a Board member learns of any facts which, under the provisions of this Section, warrant recusal from a case or proceeding before the Board itself, they shall recuse and notify the Board of such recusal. If the General Counsel, Chief Administrative Law Judge, or Division Chief of the State Mediation and Conciliation Service learns of any facts which, under the provisions of this Section, warrant recusal from a case or proceeding in which they would otherwise be directly or indirectly involved, they shall recuse, notify the Board of such recusal, and designate a replacement to act in their place regarding such case or proceeding. If any other Board agent, conciliator, mediator, or PERB official, employee, or contractor learns of any facts which, under the provisions of this Section, warrant recusal from a case or proceeding in which they might otherwise be directly or indirectly involved, they shall notify their supervisor, who shall take appropriate action.

(d) Any party to a case or proceeding before the Board itself may file directly with a Board member a written motion for recusal. The motion shall set forth by competent evidence all relevant facts. A motion for recusal must be filed and served on all parties no later than twenty (20) days after the party seeking recusal first knew or should have known that the Board member was eligible to be assigned to a panel in the case or proceeding and should be recused from the case or proceeding. Any response to such a motion by another party must be filed and served on all parties within ten (10) days after service of the motion. There shall be no reply briefs unless requested by the Board. The Board member subject to the recusal motion shall decide the motion. If the motion is denied, then the party seeking recusal can seek review from the Board itself within ten (10) days from such denial. Any response by another party to such a request for review must be filed and served on all parties within ten (10) days after service of the motion. There shall be no reply briefs regarding such a request for review, unless requested by the Board.

(e) Any party to a case or proceeding that is not before the Board itself may file a motion for recusal directly with any Board agent, conciliator, or mediator to whom the matter is assigned. Such motion shall be written, or if oral, reduced to writing within 24 hours of the motion. The motion shall set forth by competent evidence all relevant facts. A motion for recusal must be filed no later than twenty (20) days after the party first knew or should have known that the Board agent, conciliator, or mediator has been assigned a formal role in the case or proceeding. Any response to such a motion by another party must be filed and served on all parties within ten (10) days after service of the motion. There shall be no reply briefs unless requested by the Board agent. The Board agent, conciliator, or mediator subject to the recusal motion shall decide the motion, unless otherwise ordered. If the motion is granted, a new Board agent, conciliator, or mediator shall be assigned. If the motion is denied, the party seeking recusal may, within ten (10) days after its motion for recusal is denied, file with the Board itself a request for special permission to appeal such denial. If the Board does not grant special permission to appeal the denial, the party seeking recusal may file an appeal after hearing or investigation and issuance of any decision, and may choose to combine such an appeal with an appeal or exceptions as to the merits.

(f) Any party aggrieved by the Board's determination regarding a motion for recusal may include the matter in a writ of extraordinary relief filed pursuant to Government Code Section 3509.5, 3520, 3524.73, 3542, 3564, 71639.4 or 71825.1 or Public Utilities Code section 99562 seeking judicial review of the Board's decision on the merits, or, in cases reviewed by the Board itself pursuant to Section 32635, in a writ proceeding in superior court challenging the Board's refusal to issue a complaint.

(g) Nothing herein shall preclude any person subject to recusal from invoking the rule of necessity as provided for under section 87101 of the Government Code.
