Mich. Comp. Laws § 492.108

Sec. 8. (a) The administrator may reject any application for license or any application for renewal of a license if he is not satisfied that the financial responsibility and the general fitness of the applicant and of the owners, partners or members thereof, if the applicant be a partnership or association, and of the officers and directors, if the applicant be a corporation, are such as to warrant the belief that the business for which application for license is filed will be operated in accordance with the provisions of this act. (b) Whenever the administrator rejects an application for license he shall mail a notice of such action to the applicant and the applicant may, within 30 days of the date of such notice, appeal from such action to the circuit court in the manner provided for in section 9, subsection (d) of this act. (c) Whenever the administrator rejects an application for license, he shall retain the license fee which accompanied the application, to defray costs of investigation.
