The Finnish Yearbook of International Law aspires to honour and strengthen the Finnish tradition in international legal scholarship. Open to contributions from all over the world and from all persuasions, the Finnish Yearbook stands out as a forum for theoretically informed, high-quality publications on all aspects of public international law, including the international relations law of the European Union. The Finnish Yearbook publishes in-depth articles and shorter notes, commentaries on current developments, book reviews and relevant overviews of Finland's state practice. While firmly grounded in traditional legal scholarship, it is open for new approaches to international law and for work of an interdisciplinary nature. The Finnish Yearbook is published for the Ius Gentium Association (the Finnish Society of International Law) by Hart Publishing.
