Okla. Admin. Code § 310:2-21-30
Any party appealing a final agency decision of an administrative law judge or the Commissioner of Health must promptly file a file-stamped copy of the Petition For Judicial Review or other document initiating appellate review with the Hearing Clerk of the Office of Administrative Hearings in order to provide sufficient notice to prepare and transfer the record to the reviewing court in compliance with 75 O.S. § 320. Any party may submit by electronic means in PDF compatible format to the Office of Administrative Hearings and the opposing counsel a suggested Index of Record of Proceedings to be used by the Hearing Clerk in preparing the record for transmittal to the district court. If part of the administrative record is subject to a protective order, or includes a stipulation by the parties to limit the administrative record for purposes of judicial review, the suggested Index of Record must specifically describe any part of the record subject to the protective order or to the stipulation. Electronic recordings of an individual proceeding will be submitted to the reviewing court without transcription, unless otherwise required by the reviewing court; in such case, the expense of transcription shall be taxed and assessed pursuant to Article II of the Oklahoma Administrative Procedures Act.
