Mich. Comp. Laws § 168.30g
If a board of county canvassers created under this act is required to perform its statutory duties and because of illness or absence of members of the board of county canvassers a quorum is not present, the clerk of the county may appoint a sufficient number of temporary members to constitute a quorum. The appointment shall be made by the county clerk from party recommendations on file, if available. The appointments shall be of the same political party as the ill or absent members of the board of county canvassers. A temporary appointee to the board of county canvassers must possess all of the qualifications required for regular membership on that board of county canvassers. Temporary appointees shall serve only until the business on hand has been transacted.
