Section 2200.73 - Interlocutory review(a)General. Interlocutory review of a Judge's ruling is discretionary with the Commission. A petition for interlocutory review may be granted only where the petition asserts and the Commission finds:(1) That the review involves an important question of law or policy that controls the outcome of the case, and that immediate review of the ruling will materially expedite the final disposition of the proceedings or subsequent review by the Commission may provide an inadequate remedy; or(2) That the ruling will result in a disclosure, before the Commission may review the Judge's report, of information that is alleged to be privileged.(b)Petition for interlocutory review. Within 7 days following the service of a Judge's ruling from which review is sought, a party may file a petition for interlocutory review with the Commission. Responses to the petition, if any, shall be filed within 7 days following service of the petition. Service of the filed petition on the other parties and intervenors shall be accomplished in a manner prescribed in § 2200.7(c) . A copy of the petition and responses shall be filed with the Judge. The petition is denied unless granted within 30 days of the date of receipt by the Commission's Executive Secretary.

In its discretion the Commission may refuse to accept for filing a petition or response that fails to comply with this disclosure requirement. A corporate party filing the declaration required by this paragraph shall have a continuing duty to advise the Executive Secretary of any changes to its declaration until the petition is deemed denied or a decision is issued on the merits.(c)Denial without prejudice. The Commission's decision not to grant a petition for interlocutory review shall not preclude a party from raising an objection to the Judge's interlocutory ruling in a petition for discretionary review.(d)Stay -(1)Trade secret matters. The filing of a petition for interlocutory review of a Judge's ruling concerning an alleged trade secret shall stay the effect of the ruling until the petition is deemed denied or ruled upon.(2)Other cases. In all other cases, the filing or granting of a petition for interlocutory review shall not stay a proceeding or the effect of a ruling unless otherwise ordered.(e)Judge's comments. The Judge may be requested to provide the Commission with written views on whether the petition is meritorious. When the written comments are filed with the Commission, the Judge shall serve the comments on all parties in a manner prescribed in § 2200.7(c) .(f)Briefs.
