Any applicant under section 4 of this act or any licensee, being dissatisfied with any rule, regulation, order, demand, ruling, or finding (hereinafter in this section referred to as an order) whatsoever, made by the commissioner under and by virtue of the provisions of this act, may, within 30 days from the issuance of such order and the giving of notice thereof as required herein, commence an action in the circuit court in chancery for the county of Ingham, or in the chancery court of the county in which is located the place of business of such licensee or applicant concerning which such rule, regulation, order, demand, ruling or finding was made, against the commissioner as defendant to vacate and set aside such order on the ground that the same is unlawful or unreasonable or not correct as to the facts, or that any regulation or practice fixed in such order is unlawful or unreasonable. In such action the trial shall be de novo and the court shall not be bound by any finding of fact or law on the part of the commissioner, and the burden of proof shall be on the commissioner. The same shall proceed, be tried and determined as other chancery suits and appeal therefrom may be taken by any party to the supreme court in the same manner as from other chancery suits. Any party to such suit may introduce original evidence in addition to the transcript of evidence taken before the commissioner. The said circuit court in chancery is hereby given jurisdiction of such suits and empowered to affirm, modify, vacate, or set aside the order of the commissioner in whole or in part and to make such other order or decree as the court shall decide to be proper and in accordance with the facts and the law. In all actions and proceedings in court arising under this section of this act, all process shall be served and the practice and rules of evidence shall be the same as in actions in equity except as otherwise herein provided.
