Mich. Comp. Laws § 32.563
If the United States is at war or if any other emergency is declared by the president or the congress of the United States or by the governor or legislature, any organization, unit or detachment of the military forces of this state, by direction of the governor and upon order of the officer in immediate command thereof, may continue in fresh pursuit of insurrectionists, saboteurs, enemies or enemy forces beyond the borders of this state into another state, until they are apprehended or captured by such organization, unit or detachment, or until the military or police forces of such other state or the forces of the United States have had a reasonable opportunity to take up the pursuit or to apprehend or capture the persons pursued, if the other state has given authority by law for such pursuit by the forces of this state. Except as otherwise provided by law, a person who is apprehended or captured in another state by forces of this state shall be surrendered without unnecessary delay to the military or police forces of the state in which he is taken or to the United States. The surrender does not constitute a waiver by this state of its right to extradite or prosecute the person for a crime committed in this state.
