The powers of arbitrators in international commercial arbitration are based on the agreement of the parties, usually set forth in an arbitration clause contained in a contract between the parties or in a separate agreement to arbitrate. Increasingly, however, arbitrators are exercising powers that are not derived specifically from a party agreement, but rather may be implied or inherent. The terms ‘implied’ and ‘inherent’ are frequently used rather loosely, and sometimes interchangeably. This chapter develops a framework for understanding and using the terms, so that parties, arbitrators, and courts can employ common meanings and concepts when considering arbitral powers. Implied and inherent powers, properly exercised, can help ensure that the arbitral process fulfils its promise of providing a fair, ethical, and reasonable way to resolve disputes.
