908.50—Interlocutory review.

(a) General rule. The Board of Directors may review a ruling of the presiding officer prior to the certification of the record to the Board of Directors only in accordance with the procedures set forth in this section.
(b) Procedure. Any motion for interlocutory review shall be filed by a party with the presiding officer within ten (10) days of his ruling. Upon the expiration of the time for filing all responses, the presiding officer shall refer the matter to the Board of Directors for final disposition. In referring the matter to the Board of Directors, the presiding officer may indicate agreement or disagreement with the asserted grounds for interlocutory review of the ruling in question.
(c) Scope of review. The Board of Directors may exercise interlocutory review of a ruling of the presiding officer if it finds that—
(1) The ruling involves a controlling question of law or policy as to which substantial grounds exist for a difference of opinion;
(2) Immediate review of the ruling may materially advance the ultimate termination of the proceeding;
(3) Subsequent modification of the ruling at the conclusion of the proceeding would be an inadequate remedy; or
(4) Subsequent modification of the ruling would cause unusual delay or expense.
(d) Suspension of proceeding. Neither a request for interlocutory review nor any disposition of such a request by the Board of Directors under this section suspends or stays the proceeding unless otherwise ordered by the presiding officer or the Board of Directors.
