Arbitration is a non-judicial, dispute resolution procedure. Generally, there is a hearing with testimony from witnesses before one or more arbitrators. At the end of the hearing, the arbitrator(s) issue an award, which is final and binding regarding all matter submitted to them.
"It is beyond cavil that arbitration is a matter of contract and a party cannot be required to submit to arbitration any dispute which he has not agreed so to submit."
