Arbitral tribunal

In contrast to a sole arbitrator, a collegial body generally consisting of three arbitrators. Usually each party nominates one arbitrator and the two arbitrators so nominated appoint the third, who acts as the chairman of the arbitral tribunal. In some instances, and in particular in multiparty arbitrations, it may be necessary or desirable to have all three arbitrators appointed directly by an arbitral institution or other appointing authority. It is possible to envisage an arbitral tribunal comprising more than three arbitrators, or two arbitrators only, subject to the mandatory provisions of some arbitration laws that prohibit an even number of arbitrators.
