The "Assimilated Law – The Role and Future of Retained EU Law in the UK" conference is scheduled for 13-14 April 2026 at the University of Oxford. Organized by Professor Anne Davies and Dr. Johannes Ungerer, and funded by the Institute of European and Comparative Law as part of its 30th anniversary events, this conference aims to explore the concept of assimilated law that emerged in the UK post-Brexit.
The conference will address pressing questions concerning the application, interpretation, and future development of assimilated law in the UK. It will feature discussions on general themes and specific issues related to assimilated law, bringing together legal scholars and practitioners to establish a common understanding of its practices and challenges.
The event will include keynote lectures, panel discussions, and networking opportunities. Notable speakers such as Lord Sales, Lord Mance, and Professor Catherine Barnard will contribute to the discourse, providing valuable insights into the evolving landscape of UK law post-Brexit.
Legal professionals, academics, and policymakers interested in the implications of retained EU law in the UK should attend to gain a comprehensive understanding of assimilated law and its future trajectory.
