Function of Equity in International Law

This book provides a systematic and comprehensive study of the legal concept of equity as it operates in contemporary international law. A principle with a long pedigree, equity has been present in legal thought and in municipal legal systems since antiquity. Introduced in international legal decisions through claims commissions and arbitral tribunals, equity became progressively part and parcel of the international law mainstream. From international culturalheritage law to the law on climate change, from maritime boundary delimitations to decisions on security for costs in investment arbitration, the relevance of equity is more far-reaching than has previously been acknowledged. In contrast with earlier studies on the topic, this book is informed by a body of judicial and arbitral case law that has never been so substantial and varied. It also draws extensively on the prolific case law of investment tribunals, gaining insights from a valuable source that is typically overlooked in public international law scholarship. As the importance of international law increases, covering continuously new domains, the value of equity increases with it. It is this new equity in theinternational law of the 21st century that this book explores.

The book makes an important contribution to the doctrine and principle of equity in international law. Reviewing the case law of international courts and tribunals, the author excels and succeeds in expounding the relevance of the principle of equity and of derived and related concepts in everyday international jurisprudence., The author has succeeded in exposing with great clarity and precision a highly technical and controversial legal topic and the book will definitively constitiute a relevant reference for both academics and practitioners, Catharine Titi has done excellent work synthesizing an enormous amount of different legal sources, including treaties, case law, and legal scholarship, and convincingly proves the book's central thesis.
