The reform of the Investor-State Dispute Settlement (ISDS) mechanism has become one of the more controversial issues in the study of international investment law. This concise and insightful book studies the role of the ISDS mechanism in the legalization, and legitimacy, of the international investment law regime.
Providing a fresh, interdisciplinary perspective on ISDS through the constructivist theory of international relations, this book argues that reforming ISDS can contribute to the legalization of international investment law, but such a contribution is subject to both “institutional” and “internal” limitations. Chapters investigate the notion of legalization in the context of international investment law, the limitations of adjudicative bodies in advancing the legitimacy of international law, and the relationship between the level of shared understandings and choices of institutionalization. Based on comparative studies of international regimes, this book cautions against radically institutionalizing the dispute settlement regime through the establishment of the multilateral investment court.
