Michigan Compiled Laws, Chapter 257. Motor Vehicles § 257.250

Sec. 250.(1)If the secretary of state receives a complaint against a licensee that merits an investigation, the secretary of state must notify the licensee, and the complaint must be made available to the licensee at no charge. Before denying, revoking, suspending, or refusing to renew a dealer's license the secretary of state shall do all of the following:

(2)A final order of the secretary of state under subsection (1)(d) is final unless, within 30 days after notice of such order is mailed by the secretary of state to the person whose application or license is denied, revoked, suspended or refused, the licensee appeals the final order to the circuit court for the county in which the licensee resides or maintains a place of business or to the circuit court for the county of Ingham. On appeal, the court shall review both law and facts as disclosed by the record, and may in its discretion receive newly discovered evidence, but shall not conduct a hearing de novo. The court may confirm, modify, or set aside such order and make such further orders as justice may require.
