If either the aggrieved party or the commissioner applies to the court for leave to adduce additional 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 or other good cause, the court may order the additional evidence to be taken by the commissioner under such conditions as the court considers proper.
