Tim McCormack participated in the final session of the International Group of Experts (IGE) for the drafting of Tallinn 2.0 – the Tallinn Manual on the International Law Applicable to Cyber Operations – in Tallinn 19-23 March 2016. The IGE adopted the final version of the Manual and following final editing, the Manual will be sent to Cambridge University Press for publication in the 2nd half of 2016. As usual, the IGE session was lively and robust and all the members are pleased with the final product. Deliberations of the IGE were greatly assisted by extensive peer-reviewer comments as well as comments by a number of States on the drafts of each of the chapters. It is hoped that the Manual will appear in print before the end of 2016.
