This book analyses the principle of equality from three perspectives: public international law, private international law and EU law. It is the first book in English providing a comprehensive overview of this principle in these areas of law and showing the current trends and issues concerning its application. Its main goal is to understand whether and to what extent the principle of equality has been affirmed in public and private international law, as well as EU law, and what - if any - the common core of this principle is.The analysis carried out in this contributed volume starts from general analyses of the principle of equality in the areas of the law covered by the book and then discusses the principle in more specific areas, such as human rights law, international adjudication (including investment law) and the law of international organizations. The book is intended to become a benchmark for academics dealing with matters of equality in public international law, private international law and EU law. It will be a useful tool for practitioners too, the collected chapters being based on the relevant case law dealing with the principle of equality.

This book analyses three key concepts, global public goods, global commons, and fundamental values, as tools geared towards the protection of the general interests of the international community. After providing an overview of these concepts, the book examines how international law has responded to them in a wide range of fields, and investigates how global governance has improved, or worsened, this response. Contributions from a group of experts explore the legal foundations of general interests, and discuss which interests have or have not been deemed to deserve the protection of international law. Other chapters focus on whether, and to what extent, it is appropriate that international law intervenes to regulate such interests, considering the interplay between multiple actors including states, international and regional organisations, and non-state actors. The book explores how states and other actors have used international law to protect general interests, what lessons can be learned from these efforts, and what significant challenges still need to be addressed.
