Upon receiving an application for a supplier’s license, the department may require the applicant, or if the applicant is a corporation, limited liability company or partnership, its officers, directors, stockholders and members, to appear and testify under oath on the contents of the application. If the department determines that the supplier’s license applicant possesses the requisite qualifications, a license shall be issued to the bingo supplier. A license issued under this section shall be effective for one year from the first day of the month of its issuance, and may be renewed annually. If the application is not approved, the department shall notify the applicant in writing of such action. Within 10 days after receipt of such notification, the applicant may demand a hearing before the department. At the hearing, the burden of proof shall be on the applicant to establish his or her qualifications and the merit of the application. The fee, less reasonable administrative costs, shall be refunded to the applicant upon entry of an order denying an application after hearing, or upon expiration of the period during which a hearing may be demanded.
