Mich. Admin. Code R. 792.10442
Rule 442. An administrative law specialist assigned by the director of the regulatory affairs division shall review a complaint to determine if the complaint states a prima facie case within the commission's jurisdiction. If the commission finds that a complaint does not state a prima facie case or does not conform to these rules, it shall notify the complainant or the complainant's attorney that the complaint is rejected, give the reasons for the rejection, and return the complaint. Nothing in this rule prohibits a complainant whose complaint has been rejected from amending and refiling the complaint. Upon the filing of a formal complaint that conforms to the provisions of R 792.10441 of these rules and states a prima facie case, the commission, acting through its staff, may commence an investigation of the matters raised in the complaint.
