Even though UN Security Council resolutions may have major consequences for the disputes and states concerned, some of the resolutions are ambiguous in their meaning. This raises questions about the appropriate means of interpreting Security Council resolutions. In the process of interpreting Security Council resolutions, explanation of votes may have a role. Explanation of votes are not provided for in Security Council Provisional Rules of Procedure. However, members of the Security Council may make statements in connection with their votes. These remarks are in the Council called "statements before the vote" or "statements after the vote". Dr. Klamberg will discuss the phenomena of explanation of votes and their status, including an analysis of explanation of votes made in relation to selected examples of controversial Security Council resolutions. Dr Mark Klamberg is a research fellow during 2018/2019 at the Institute of European and Comparative Law (IECL) and affiliated with Christ Church College, Oxford. He is an Associate Professor, Senior Lecturer in Public International Law at Stockholm University and a visiting lecturer at Edinburgh University. He is currently the principal investigator of the project "Does International Law Matter? The UN Security Council and State Actions" funded by the Swedish Research Council 2018-2021.

He is the chief editor of the 'Commentary on the Law of the International Criminal Court' (TOAEP, 2017). He has also published articles in International Criminal Law Review, Journal of International Criminal Justice, Nordic Journal of International Law, Georgetown Journal of International Law and book sections published by Martinus Nijhoff Publishers and Oxford University.
