(a) Any person aggrieved by a final order of the commissioner may obtain a review of the order in the circuit court of Kanawha county by filing in court, within sixty days after the entry of the order, a written petition praying that the order be modified or set aside in whole or in part. A copy of the petition shall be forthwith served upon the commissioner and thereupon the commissioner shall certify and file in court a copy of the filing and evidence upon which the order was entered. When these have been filed, the court has exclusive jurisdiction to affirm, modify, enforce or set aside the order, in whole or in part. The findings of the commissioner as to the facts, if supported by competent, material and substantial evidence, are conclusive. If either party applies to the court for leave to adduce additional material evidence, and shows to the satisfaction of the court that there were reasonable grounds for failure to adduce the evidence in the hearing before the commissioner, the court may order the additional evidence to be taken before the commissioner and to be adduced upon the hearing in such manner and upon such conditions as the court considers proper. The commissioner may modify his findings and order by reason of the additional evidence and shall file in court the additional evidence together with any modified or new findings or order. The judgment of the court shall be final, subject to review by the Supreme Court of Appeals.
(b) The commencement of proceedings under subsection (a) does not, unless specifically ordered by the court, operate as a stay of the commissioner's order.
