Okla. Admin. Code § 775:15-3-1
Any person may file a citizen complaint with the Board in regard to any person licensed or certified by the Board or any person otherwise under the Board's statutory jurisdiction. Citizen complaints may be written or oral. The Staff may require complainants to reduce oral complaints to writing if such would facilitate review of the complaint. The Staff shall investigate all facially credible citizen complaints over which the Board would reasonably have jurisdiction. In addition, the Staff may refer complaints to other entities, such as the Oklahoma State Bureau of Investigation, Oklahoma Bureau of Narcotics and Dangerous Drugs, other law enforcement agency, or appropriate district attorney, for action when such other entity has jurisdiction.
