An appeal from the commissioner shall be taken only from an order entered after hearing or an order refusing a hearing. Any person aggrieved by any such order may, within thirty days after the order has been mailed or delivered to the persons entitled to receive the same, or within thirty days after an order denying rehearing has been so mailed or delivered, appeal to the circuit court of Kanawha county, or the judge thereof in vacation, by presenting a written petition to such court or judge and mailing a copy thereof to the commissioner. Upon the receipt of such copy the commissioner shall forthwith transmit to the clerk of such court the record of the proceedings before him The court or judge shall fix a time for hearing upon said petition at his earliest convenience. Notice in writing of the time and place of said hearing shall be given by petitioner to the commissioner at least fifteen days prior thereto. The court or judge shall, without a jury, hear and determine the matter upon the record of proceedings before the commissioner, except that for good cause shown the court may permit the introduction of additional evidence, and may enter an order revising or reversing the order of the commissioner, or may affirm such order, or remand the action to the commissioner for further proceedings. Pending such appeal the order of the commissioner shall be in full force and effect until final determination, unless the commissioner shall in his discretion have stayed the effect of his order pending final determination of the appeal or unless the court or judge thereof before whom the appeal is pending shall enter an order staying the commissioner's order until final determination. The judgment of the circuit court may be reviewed upon appeal by the Supreme Court of Appeals in the same manner as other civil cases to which the state is a party.
