199—7.25 (17A,476) Interlocutory appeals. Upon written request of a party or on its own motion, the board may review an interlocutory order of the presiding officer. In determining whether to do so, the board may consider the extent to which granting the interlocutory appeal would expedite final resolution of the case and the extent to which review of that interlocutory order by the board at the time it reviews the proposed decision would provide an adequate remedy. Any request for interlocutory review must be filed within ten days of issuance of the challenged order, but no later than the time for compliance with the order or ten days prior to the date of hearing, whichever is first.
