Mich. Comp. Laws § 168.388: Metropolitan district officer; vacancy filled by appointment; election; notice.

Sec. 388.

(1) If less than a majority of the offices of metropolitan district officer of a metropolitan district become vacant, the remaining metropolitan district officers shall fill each vacant office by appointment. If a vacancy in the office of metropolitan district officer is not filled within 30 days after the vacancy occurs or if a majority of the offices of metropolitan district officer of a metropolitan district become vacant, the county election commission of the county in which the largest number of registered electors of the metropolitan district reside shall fill each vacancy by appointment. An individual appointed under this subsection serves until a successor is elected and qualified.

(2) If a vacancy occurs in an office of metropolitan district officer more than 7 days before the nominating petition filing deadline as provided in section 386 for the regular metropolitan district election that is not the regular metropolitan district election at which a successor in office would be elected if there were no vacancy, the person appointed shall hold office only until a successor is elected at the next regular metropolitan district election in the manner provided by law and qualifies for office. The successor shall hold the office for the remainder of the unexpired term. This subsection applies regardless of whether an individual is appointed under subsection (1) to fill the vacancy.

(3) Within 3 days after an appointment is made to fill a vacancy in an elected office in a metropolitan district, the secretary of the legislative body of the metropolitan district shall notify the metropolitan district election coordinator, in writing, of the name, address, and office of the person who vacated the office as well as the person filling the office.
