Compiled Laws, Chapter 28. Michigan State Police § 28.584

Sec. 4. (1) A public body shall not create a law enforcement agency under this act unless, before that agency is created, the governing entity obtains the approval of the prosecuting attorney of each county within which the public body owns, maintains, or controls property. If the property of the public body is located entirely within 1 city, the public body also shall obtain the approval of the chief of police of that city. If the property of the public body is not located entirely within 1 city, the public body also shall obtain the approval of the sheriff of each county within which the public body owns, maintains, or controls property. If all the property of the public body is located within a county which does not have a first class school district as defined in 1976 PA 451,  1 the public body shall also obtain the approval of the county sheriff. Before granting that approval, the prosecuting attorney, the sheriff, if required, and the chief of police, if required, shall make a determination that the proposed law enforcement agency is needed to assure adequate public safety on the property of the public body and that the proposed agency can comply with the minimum guidelines established under section 6.  2

(2) In addition to the requirements of subsection (1), before creating a law enforcement agency under this act, the governing entity shall hold not fewer than 2 public hearings in the proposed law enforcement agency's jurisdiction on the question of creating the proposed law enforcement agency. The governing entity shall make a record of the hearing and shall provide copies of the record to all of the prosecuting attorneys, sheriffs, and chiefs of police from whom approval is required by this section.
