Mich. Comp. Laws § 168.590g: Person filing qualifying petition; restrictions; selecting single office to which candidacy restricted; failure to make selection.

Sec. 590g.

A person who files a qualifying petition shall not file a partisan nominating petition or filing fee, and shall not be nominated as a candidate by write-in vote or by a political party convention, caucus, or committee, for an office to be elected at the election for which the person has filed a qualifying petition or at an election held during the same calendar year as that election.

A person who files a qualifying petition for more than 1 office, which offices are incompatible and the terms of which offices run concurrently or overlap, shall select the 1 office to which his or her candidacy is restricted not later than 4 p.m. of the third day after the last day for filing a qualifying petition. Failure to make this selection disqualifies the person as a candidate for the offices for which qualifying petitions were filed, and the petitions shall not be canvassed.
