François Delerue Wins 2021 Book Prize of European Society of International Law

Award Ceremony

Associate Fellow François Delerue was awarded the 2021 Book Prize of the European Society of International Law for his book Cyber Operations and International Law published by Cambridge University Press in February 2020.

The Awarding Ceremony took place on Friday 10 September during the 2021 Annual Conference of the European Society of International Law, in Stockholm (Sweden), and was followed on Saturday 11 September by a discussion on the book with Professor Vasilka Sancin (University of Ljubljana), one of the three members of the jury. The two other members of the jury were H.E. Judge Peter Tomka (Member and past President of the International Court of Justice) and Professor Marcelo Kohen (The Graduate Institute, Geneva).

François Delerue’s book offers a comprehensive analysis of the international law applicable to cyber operations, including a systematic examination of attribution, lawfulness and remedies. It demonstrates the importance of countermeasures as a form of remedies and also shows the limits of international law, highlighting its limits in resolving issues related to cyberoperations. There are several situations in which international law leaves the victim State of cyber operations helpless. Two main streams of limits are identified. First, in the case of cyber operations conducted by non-state actors on the behalf of a State, new technologies offer various ways to coordinate cyber operations without a high level of organization. Second, the law of State responsibility offers a range of solutions to respond to cyberoperations and seek reparation, but it does not provide an answer in every case and it cannot solve the problem related to technical capabilities of the victim.
