Arbitral tribunal

An arbitral tribunal (or arbitration tribunal) is a panel of one or more adjudicators which is convened and sits to resolve a dispute by way of arbitration. The tribunal may consist of a sole arbitrator, or there may be two or more arbitrators, which might include either a chairman or an umpire. Typically, members selected to serve on the tribunal are professionals with expertise in law and mediation, although some scholars have suggested that the ideal composition of an arbitral tribunal should include at least one economist, particularly in cases that involve questions of asset or damages valuation.

The parties to a dispute are usually free to determine the number and composition of the arbitral tribunal. In some legal systems, an arbitration clause which provides for two arbitrators (or any other even number) is understood to imply that the appointed arbitrators will select an additional arbitrator as a chairman of the tribunal, to avoid deadlock arising. Different legal systems differ as to how many arbitrators should constitute the tribunal if there is no agreement.

Arbitral tribunals are usually constituted (appointed) in two types of proceedings:

Permanent tribunals tend to have their own rules and procedures, and tend to be much more formal. They also tend to be more expensive, and, for procedural reasons, slower.

The parties are generally free to determine their own procedure for appointing the arbitrator or arbitrators, including the procedure for the selection of an umpire or chairman. If the parties decline to specify the mode for selecting the arbitrators, then the relevant legal system will usually provide a default selection process. Characteristically, appointments will usually be made on the following basis:

Most arbitration clauses will provide a nominated person or body to select a sole arbitrator if the parties are unable to agree (for example, the President of the relevant jurisdiction's Bar Association, or a recognised professional arbitration organisation such as the LCIA, or a relevant professional organisation). In default of such a provision, where the parties are unable to agree, an application for an appointment is usually made to the court.

A well drafted arbitration clause will also normally make provision for where a party to the dispute seeks to cause delay by refusing to make or agree an appointment. Often this will allow the "non-defaulting" party to appoint a sole arbitrator and for the arbitration to proceed on that basis.
