The fifth volume of the Balkan Yearbook of European and International Law (BYEIL) discusses diverse and actual legal topics of international and comparative dimensions and angles. The BYEIL 2023 focuses on the special topic of Human Rights at Multiple Levels and contributes to the extensively researched field characterised by emerging trends, with the authors providing a deeper and more concise understanding of human rights-related issues. Discussions surrounding indivisibility, interdependence, universalism versus cultural relativism inevitably led to exploring human rights at various levels. The two permanent sections on European Law and International Law deal with recent developments in these highly dynamic and developing areas. They serve as a forum for scholarly discourse on these topics from the South-East European perspective.
