The European Yearbook of International Economic Law 2025 examines current transformations and emerging challenges in international and European economic law, with particular attention to the growing intersection between global sports and economic law.

The volume's Focus Section, Global Sports and International and European Economic Law, gathers contributions on the legal challenges raised by sport's expanding economic and societal weight. Spanning competition, investment, arbitration, intellectual property, human rights, sanctions, and sports governance, these contributions examine how international and European economic law is responding to global sport, and where existing legal frameworks are being tested.

The volume also includes a special In Memoriam section honouring Prof. Dr. Jörg Philipp Terhechte, EYIEL’s founding editor, and his work on futures of international and European economic law.

Drawing on perspectives from diverse geographical and legal backgrounds, EYIEL 2025 offers a timely, forward-looking contribution to the study of international and European economic law.
