Jurisdiction of the arbitrator

Authority or jurisdiction of an arbitrator to hear and decide a particular issue placed before him/her in an arbitration hearing. The jurisdiction of the arbitrator’s deliberation is frequently restricted to the issue presented in the original grievance. In other situations the arbitrator’s jurisdiction is limited to either (1) an issue or issues agreed to by the parties to the arbitration, or (2) the authority delegated to the arbitrator to frame the issue.
