To ensure effective arbitration and to increase the general credibility of the arbitral process, arbitrators will sometimes sit as a panel, usually consisting of three arbitrators. Often the three consist of an expert in the legal area within which the dispute falls (such as contract law in the case of a dispute over the terms and conditions of a contract), an expert in the industry within which the dispute falls (such as the construction industry, in the case of a dispute between a homeowner and his general contractor), and an experienced arbitrator.
