Participants in international commercial arbitration have long recognized the need to maintain arbitration as an effective and therefore attractive alternative to litigation, while still ensuring that its use is predicated on the consent of the parties and that the resulting awards command respect. A priori, at least, all participants—parties, counsel, arbitrators, arbitral institutions—have an interest in ensuring that arbitration delivers the various advantages associated with it, notably speed, economy, informality, technical expertise, and avoidance of national fora, while producing awards that withstand judicial challenge and otherwise enjoy legitimacy.
