Okla. Admin. Code § 735:80-13-11
Hearings will be conducted by a hearing examiner, who must be a licensed attorney at law, who has been designated by the Treasurer. The Treasurer may conduct a hearing without designating a hearing examiner. The hearing examiner shall have authority to conduct hearings, to examine witnesses, to rule upon motions, to rule upon the admissibility of evidence, to continue or recess any hearing, to control the record, and to make recommendations to the Treasurer. If for any reason a hearing examiner cannot continue on a case, the Treasurer shall designate another hearing examiner with the above qualifications, who will become familiar with the record and perform any function remaining to be performed without the necessity of repeating any previous proceedings.
