Critical to the effectiveness of an arbitral seat is its arbitration law, a feature that, unlike the geographic location or the basic infrastructure, can readily be improved by legislators who appreciate the financial benefits of attracting international arbitrations. The forthcoming GAR–CIArb Seat Index, which is based on the London Principles, will establish a reliable and accessible reference point for commercial parties to make wise choices of seats and for all to be aware of the relative strengths and weaknesses of seats on the world stage. It is hoped that this will provide the incentive to legislators to reform arbitration statutes where this is necessary.
