The Baltic Yearbook of International Law is published under the auspices of the Baltic Editorial Board within the framework of cooperation between the Riga Graduate School of Law and Brill/Nijhoff Publishers. The Yearbook aims to bring to the international debate issues of importance in the Baltic States, providing a forum for views on topical international law themes from 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 which is unavailable elsewhere.

This volume carries particularly extensive practice reports because they exemplify the position of the Baltic States on relevant international law and State practice with regards to the full-scale invasion by the Russian Federation of Ukraine in February 2022.

Volume 22 is an open access volume and includes articles which emerged from a research forum of the European Society of International Law entitled "Regional Developments of International Law in Eastern Europe and Post-Soviet Eurasia". The research forum was held on 27-28 April 2023 at the University of Tartu in Estonia. The articles deal with diverse issues such as Western and Russian approaches to cyber conflict and international law, human rights in Central Asia, the legal status of the Caspian Sea, Russian approaches to post-Soviet secession, desovietization of international law, provisional measures in Ukraine’s international adjudication cases against Russia, East European civilian non-violent defence against Russian warfare and aspects of international humanitarian law, and Russia’s approaches to the freedom of navigation. From the practice of the Baltic States, there is also a general article on Latvian responses to the migration crisis at Latvia’s border with Belarus.
Open access for the volume was funded by Grant PRG969 from the Estonian Research Council.
