Mich. Comp. Laws § 338.1088
The governing board of a private college or university shall not create a private college security force under section 37 unless, before that security force is created, the governing board obtains the approval of the prosecuting attorney and the sheriff of each county within which the private college or university owns, maintains, or controls property. If the property of the private college or university is located entirely within 1 city, the governing board also shall obtain the approval of the chief of police of that city. If the property of the private college or university is not located entirely within 1 city, the governing board also shall obtain the approval of the chief of police of each city within which the private college or university owns, maintains, or controls property. Before granting approval, the prosecuting attorney, the sheriff, and the chief of police, as required, shall make a determination that the proposed private college security force is needed to assure adequate public safety on the property of the private college or university. Any of the persons whose approval is required under this section may rescind that approval at any time after his or her approval was granted, in which case the private college security force is no longer authorized and shall cease to operate.
