His monograph, The Principle of Legality: A Moral Theory, is under contract with Oxford University Press. He is the co-convenor of the Irish Jurisprudence Society.

Research Interests

Conor's research interests focus on the intersection between general jurisprudence and public law theory. 

In legal philosophy, he focuses on debates around non-positivist or 'interpretivist' theories of general jurisprudence; theories that view legal obligations as genuine moral obligations. He is interested in the moral and metaphysical debates in this area, and the question of what bearing these debates have on how we think about constitutional law in particular.

In public law, Conor deploys interpretivist theories of general jurisprudence to make sense of theoretical debates in public and constitutional law. His main research project focusses on developing an interpretivist theory of statutory interpretation in UK public law. He is also interested in theorising the normative foundations of other public law doctrines, and has written, for example, on the theoretical underpinnings of procedural fairness in administrative law.

He welcomes expressions of interest in doctoral supervision in the areas of legal theory or constitutional law.
