Mich. Comp. Laws § 460.1053
The attorney general or any customer of a municipally owned electric utility or a cooperative electric utility that is member-regulated under the electric cooperative member-regulation act, 2008 PA 167, MCL 460.31 to 460.39, may commence a civil action for injunctive relief against that municipally owned electric utility or cooperative electric utility if the municipally owned electric utility or cooperative electric utility fails to meet the applicable requirements of this subpart or an order issued or rule promulgated under this subpart. The attorney general or customer shall commence an action under this section in the circuit court for the circuit in which the principal office of the municipally owned electric utility or cooperative electric utility is located. The attorney general or customer shall not file an action under this section unless the attorney general or customer has given the municipally owned electric utility or cooperative electric utility at least 60 days' written notice of the intent to sue, the basis for the suit, and the relief sought. Within 30 days after the municipally owned electric utility or cooperative electric utility receives written notice of the intent to sue, the municipally owned electric utility or cooperative electric utility and the attorney general or customer shall meet and make a good-faith attempt to determine if there is a credible basis for the action. The municipally owned electric utility or cooperative electric utility shall take all reasonable and prudent steps necessary to comply with the applicable requirements of this subpart or an order issued or rule promulgated under this subpart within 90 days after the meeting if there is a credible basis for the action. If the parties do not agree as to whether there is a credible basis for the action, the attorney general or customer may proceed to file the suit. When making a determination of whether a credible basis for the action exists, the attorney general or customer shall consider the factors listed in section 32(2).
