This volume of the Baltic Yearbook of International Law contains articles based on presentations delivered at the Annual Conference of the European Society of International Law which took place in Riga, Latvia, from 8-10 September 2016. Among the selected authors, the Yearbook is pleased to continue to introduce new authors from the region. The Baltic Yearbook of International Law is the first legal journal in the field of international law published under the auspices of the Baltic Editorial Board that attempts to bring to the international debate the issues that are of importance in the Baltic States and provides a forum for the views of, among others, Baltic international scholars on various topical themes of international law. The first volume appeared in 2001 with the symposium on the question of International Legal Status of the Baltic States. The Yearbook contains State practice reports from Estonia, Latvia and Lithuania and thus serves as an important source of information that is not available elsewhere. On several occasions the Yearbook has offered articles discussing the history of international law and current issues in Eastern Europe and the Russian Federation, thus making more accessible a regional discourse to a wider audience in the world.
