243.9. At all times during the arbitration proceedings, the arbitrator or arbitrators may, on an application, dismiss the recourse to arbitration if it is proved to them that the recourse is frivolous or clearly devoid of substance.
In such a case, the person who instituted the recourse, notwithstanding the provisions of section 243.18, shall be bound to pay the arbitration costs and the arbitrators’ fees, to the extent that the arbitrators determine in view of the circumstances.
