The Baltic Yearbook of International Law ‒ the first legal journal in the field and subfields of international law ‒ is published under the auspices of the Baltic Editorial Board. The Yearbook aims to bring to international debate issues of importance in the Baltic States, providing a forum for views on topical international law themes from both Baltic and international scholars. The first volume appeared in 2001 with a symposium on the question of the international legal status of the Baltic States. The Yearbook contains state practice reports from Estonia, Latvia and Lithuania, thus serving as an important source of international law that is unavailable elsewhere. From time to time the Yearbook offers articles discussing the history of international law and current issues in Eastern Europe and the Russian Federation, thus making regional discourse more accessible to a wider global audience. Volume 18 is the second volume of the Baltic Yearbook of International Law appearing under the aegis of cooperation between the Riga Graduate School of Law and Brill/Nijhoff Publishers. This volume is devoted to highlighting the reflections aired in Riga when the Law School was implementing the Jean Monnet Project in 2017-2019. These reflections broadly focused on the law of the European Union. The editors of the Baltic Yearbook are certain that the EU-law perspective will be of interest to international lawyers throughout the world, whether as an option or as an idea as to what the international legal order might look like with ever growing globalization and migration of the world’s people.
