2024 ESIL Monograph Prize Winner

The 2024 ESIL Monograph Prize was awarded in September 2024 during the 19th ESIL Annual Conference in Vilnius to Arianna Whelan for her book Reciprocity in Public International Law (CUP, 2023).

Jury’s decision:

The book covers a very important concept for international law in a comprehensive and elegant manner. While issues concerning reciprocity have been addressed in other works, the scope and depth of this book adds important academic and practical value to international law scholarship. The author writes with a clear and engaging style, supporting her arguments in a wealth of relevant legal sources. She provides a detailed legal analysis of the various roles and articulations of reciprocity in several key fields of public international law, including the law of treaties, the treatment of individuals, the enforcement of international law, and the jurisdiction of international courts and tribunals and human rights courts and treaty bodies. Notably, the author points out that reciprocity is not the enemy of community interests and obligations, quite the contrary, while at the same time supporting and operationalizing the principle of the sovereign equality of States.
