A Case for an International Investment Court

Abstract

The article elaborates on the lack of objective guarantees of independence and impartiality in the existing system of investment treaty arbitration. This founds a case for an international investment court to replace the existing system. The argument proceeds in three steps: (1) investment treaty arbitration is uniquely a form of public law adjudication, constituted at the international level; (2) as constituted it does not satisfy standards of independence and impartiality in public law adjudication; and (3) various reasons that might be offered to justify this failing are unsatisfactory in light of the importance of these standards. For this reason, states should be encouraged to establish an international investment court in accordance with well-known principles of judicial decision-making. Above all, alternatives to the existing system should be measured against the criteria that typically apply in public law, especially the related principles of openness and independence. Absent these criteria being met, one does not have a system that depoliticizes disputes and subjects them to the rule of law, or that warrants the utmost respect of all parties, above all developing states.
