Dr Dorota Leczykiewicz

Dr Dorota Leczykiewicz is Associate Professor of Law at the University of Oxford and Official Fellow and Tutor in Law at St Peter’s College. Her research and teaching span Tort law, comparative private law, and European Union law, with a particular focus on how legal principles and doctrines develop through judicial decision-making.

Research

In her comparative law scholarship, Dr Leczykiewicz’s work examines common-law and civil-law approaches to private law, especially in the field of Tort law. Her research explores how different legal systems conceptualise damage, rights, loss, responsibility, and remedies, and how these concepts shape the structure and operation of private law. Dr Leczykiewicz’s recent publications in comparative law include the book Comparative Reflections in Private Law: Essays in Honour of Simon Whittaker (co-editor, Oxford University Press, 2026) and the chapter ‘Violation of a Right and Tort Law’ (2026). Her earlier work in comparative law explored questions of civil liability reform, including the treatment of loss and compensation in French law.

Alongside private and comparative law, Dr Leczykiewicz’s research focuses also on EU law and the jurisprudence of the Court of Justice of the EU (CJEU). Her recent chapter, ‘The Reasoning of the Court of Justice of the EU: Challenging the Interpretation Framework’ (2026), argues for a re-evaluation of the framework commonly used to understand and evaluate CJEU case law. In her current research, Dr Leczykiewicz is examining the continuing authority of CJEU case law in the UK after Brexit.

Teaching

At St Peter’s College, Dr Leczykiewicz teaches undergraduate tutorials in Tort law, Comparative law, and European Union law. In the Faculty, she gives lectures and seminars in the same subjects. She is particularly committed to the tutorial system and encourages students to develop intellectual independence, strong analytical and confidence in legal argument. Through her teaching, students learn to engage critically with legal doctrine and understand the values underpinning the legal system.
