Michigan Compiled Laws, Chapter 333. Health § 333.8503

Sec. 8503. (1) In addition to any other penalties prescribed or remedies provided in this article, article 7,  1 and article 15,  2 the department may, on its own motion or on receipt of a complaint, and after an investigation and a hearing before an administrative law judge at which the pharmaceutical-grade cannabis licensed facility licensee is afforded an opportunity to be heard, suspend or revoke a facility license issued under this article. The department may suspend or revoke a license for any violation by the licensee, a board member, an agent, or an employee of the licensed facility or of any of the terms, conditions, or provisions of the license issued by the department. The department may administer oaths and issue subpoenas to require the presence of persons and the production of papers, books, and records necessary to the determination of any hearing that the department is authorized to conduct.

(2) The department shall provide notice of suspension or revocation, as well as any required notice of a hearing, by mailing the same in writing to the licensed facility at the address contained in the license. If a license is suspended or revoked, no part of the fees paid for the license under this article or under article 7 shall be returned to the licensee. The department may summarily suspend a license without notice pending any prosecution, investigation, or public hearing.
