Mich. Comp. Laws § 423.242: Judicial review; scope; stay.

Sec. 12.

Orders of the arbitration panel shall be reviewable by the circuit court for the county in which the dispute arose or in which a majority of the affected employees reside, but only for reasons that the arbitration panel was without or exceeded its jurisdiction; the order is unsupported by competent, material and substantial evidence on the whole record; or the order was procured by fraud, collusion or other similar and unlawful means. The pendency of such proceeding for review shall not automatically stay the order of the arbitration panel.
