Arbitration clauses in investment treaties often provide investors with a choice between ICSID arbitration, on the one hand, and rules originally drafted for commercial arbitration on the other. The Use of Commercial Arbitration Rules in Investment Treaty Disputes e studies how domestic courts and commercial arbitration institutions impact the scope of arbitral tribunal jurisdiction when commercial arbitration rules are used. Based on extensive studies of court decisions and previously-unknown arbitral awards, Joel Dahlquist's book analyses the practice of domestic courts in reviewing treaty-based jurisdiction, and explains how the two most used commercial arbitration institutions - the ICC and the SCC - have drafted, interpreted and applied their arbitration rules in treaty-based disputes.
