One additional advantage of arbitration, the parties’ ability to predetermine the law governing the resolution of the dispute, has gained growing recognition in recent years. This recognition, however, has been myopic to some extent. Some commentators see choice of law options confined either to the selection of one national legal system from several possibilities or to the selection of a single national, international, or anational legal system. Such a self-imposed limitation of the applicable law to one system of law often denies parties many of the benefits and powers allowed them in international commercial arbitration. As an alternative, an agreement may direct an arbitrator to apply different systems of law to different areas of the dispute.
