Parallel Proceedings in Investor-State Treaty Arbitration: Responses for Treaty-Drafters, Arbitrators and Parties

Despite the unique context within which parallel investment arbitrations occur, the challenges they pose to party interests, to principles including legal fairness and to the effective pursuit of dispute resolution closely resemble those posed by parallel proceedings in other domestic and international legal fora.
