Michigan Compiled Laws, Chapter 125. Planning, Housing and Zoning § 125.2339

Sec. 39. (1) Upon the entry of an order to show cause under this act, the department shall promptly notify the applicant that the order was entered and of the reasons for the order and that upon receipt of written request the matter shall be set down for a hearing to commence within 45 days after the receipt of the order unless the applicant and the department consent to a later date. If a hearing is not requested within 15 days and none is ordered by the department, an appropriate order shall be entered and remain in effect until it is modified or vacated by the department. If a hearing is requested or ordered, the department may enter an appropriate order of its determination, after notice and hearing.

(2) For the purpose of an investigation or proceeding under this act, the department may administer oaths and affirmations, subpoena witnesses, compel their attendance, take evidence, and require the production of records or other documents which the department deems relevant or material to the inquiry. Before any of the requirements of this subsection become operative, the department shall obtain an order of the circuit court for the information by a showing that there is good cause that a violation has taken place or is about to take place, and all of the subpoenas or orders shall issue from the circuit court.
