Breakfast Briefing with Keiko Kono

Towards Tallinn Manual 3.0 – Challenges and Perspectives

** CANCELLED - A new date will be circulated **


This presentation will focus on several topics covered in two editions of Tallinn Manual (TM): Tallinn Manual on the International Law Applicable to Cyber Warfare (2013) and Tallinn Manual 2.0 on the International Law Applicable to Cyber Operations (2017). It will assess where disagreements lie among TMs experts and states and how relevant TMs are to actual cyber incidents, and predict in which direction the next edition – TM 3.0 – will go. Selected topics are peacetime espionage, non-intervention, (collective) countermeasures, necessity, extra-territorial enforcement jurisdiction, and “attack” under law of armed conflict. Following Denmark’s recent release of its position paper on international law and cyber operations, this presentation will consider what Denmark is expected to do next on the matter in the coming years.
