Since the establishment of the Permanent Court of Arbitration for international dispute resolution in 1899, the number of international courts and tribunals has multiplied and the reach of their jurisdiction has steadily expanded. By providing a synthetic overview and critical analysis of these developments from multiple perspectives, this Research Handbook both contextualizes and stimulates future research and practice in this rapidly developing field. Made up of specially commissioned chapters by leading and emerging scholars, the book takes a thematic and interpretive, system-wide and inter-jurisdictional comparative approach to the main issues, debates and controversies related to the growth of international courts and tribunals. Its review of influential international judgements traverses the areas of international peace and security law, international human rights law, international criminal law, and international economic law, while also including critical reflection by practitioners. This nuanced review of the latest thinking on scholarly debates and controversies in international courts and tribunals will be both a key resource for academic researchers and a concise introduction to the subject for post-graduate students. Its chapters also contain topics of practical relevance to lawyers and international decision-makers. Contributors include: A.M. Barreto, J. Chylinski, T. Dannenbaum, W. Elmaalul, M. Farrell, K.
