Some investment arbitration tribunals have relied upon the principle of contributory fault to conclude that claimants have contributed to their own loss and should accordingly receive less compensation. The principle has not, however, been coherently applied. After analysing the use of contributory fault by tribunals and identifying factors contributing to an incoherent approach, the authors conclude that carefully crafted treaty provisions can improve the consistency of international investment arbitration by fostering a more coherent approach to both contributory fault and foreign investors’ responsibilities.
