Okla. Admin. Code § 160:15-5-2
A thorough investigation shall be conducted of each applicant, and applicants shall provide such additional information as may be requested from the applicant for that purpose. In addition, the Administrator may consult outside sources, including law enforcement agencies, and may require the applicant's consent to release such other relevant information as the Administrator may deem necessary to determine financial responsibility, experience, character and general fitness of the applicant [59:1505(A)]. It shall be within the discretion of the Administrator to determine the fitness of an applicant, provided that such discretion is not arbitrary or capricious and is, or will be, applied uniformly to all similarly situated applicants.
