At the hearing in the case of LLC Denta

At the hearing in the case of Denta LLC against Kirovsky Department Store, the plaintiff´s representative filed a motion to hear the case with the participation of arbitration assessors. In the petition, he indicated five candidates, from among whom he suggested that the court choose arbitration assessors. The representative of the defendant no objections. The arbitral tribunal independently determined two candidates for arbitration assessors and examined the case on the merits.
Was the court right? In what cases is it possible to consider cases with the participation of arbitration assessors for consideration of cases?
