In County Coll. of Morris Staff Ass'n v. County Coll. of Morris, 100 N.J. 383, 495 A.2d 865 (1985), the Supreme Court instructed: When parties have agreed, through a contract, on a defined set of rules that are to govern the arbitration process, an arbitrator exceeds his powers when he ignores the limited authority that the contract confers. The scope of an arbitrator's authority depends on the terms of the contract between the parties. Both the jurisdiction and the authority of the arbitrator are circumscribed by the powers delegated to him by the contract of the parties. Thus, an arbitrator may not disregard the terms of the parties' agreement, nor may he rewrite the contract for the parties. Id. at 391-92, 495 A.2d 865.
