R.I. Gen. Laws § 28-5-31: Additional evidence in court.

If either party applies to the court for leave to adduce additional evidence and shows to the satisfaction of the court that the additional evidence is material and that there were reasonable grounds for the failure to adduce the evidence in the hearing before the commission, its member, or agent, the court may order the additional evidence to be taken before the commission, its member, or agent and to be made a part of the transcript.
