The Role of International Courts and Tribunals in International Environmental Law

Abstract

International environmental law is one of the most dynamic fields of public international law, and has rapidly acquired great breadth and sophistication. Yet the rate of global environmental decline has also increased and is accelerating. Halting and reversing this process is a challenge of effective governance, requiring institutions that can ensure that the now impressive body of environmental norms is faithfully implemented. This thesis explores whether and to what extent international courts and tribunals can play a useful role in international environmental regimes. Consideration is given to the threefold function of adjudication in resolving environmental disputes, in promoting compliance with environmental standards, and in developing environmental rules. The thesis is divided into three Parts. The first Part examines the spectrum of adjudicative bodies that have been involved in the resolution of environmental disputes, situates these within the evolution of institutions for compliance control, and offers a reassessment of their relevance in contemporary environmental governance. The second Part critically assesses the contribution that arbitral awards and judicial decisions have made to the development of norms and principles of environmental law, examining case law relating to transboundary pollution, shared freshwater resources and marine environmental protection. In the third Part of the thesis consideration is given to three looming challenges for international environmental litigation: accommodating greater levels of public participation in adjudicative processes, resolving practical problems stemming from the interaction among multiple jurisdictions, and ensuring that specialised courts and tribunals do not apply environmental norms in a parochial manner that privileges the policy objectives of issue-specific regimes.
