Andrew Le Sueur is Head of Essex Law School since January 2017. He joined the School of Law in August 2013 as Professor of Constitutional Justice. He is a member of the Jersey Law Commission, currently leading a project on reform of administrative justice in the island. He is a Fellow at UCL Constitution Unit. He is a member of the executive committee of the International Association of Constitutional Law and serves on the executive committees of the UK Constitutional Law Association and the Statute Law Society. He has served as an adviser to several parliamentary select committees, including as legal adviser to the House of Lords Constitution Committee (2006-09). In April 2011, he was appointed as the specialist adviser to that Committee for their inquiry on the judicial appointments process.
Previously he was based at Queen Mary, University of London (Professor of Public Law 2006-13), at Birmingham (Barber Professor of Jurisprudence 2001-2006) and UCL (lecturer and reader 1988-2000). He was the first director of studies at the Institute of Law in Jersey (2009-13).
His main research interests are in the broad fields of constitutional and administrative law and justice. Currently he is working on "robot government", looking at the constitutional implications of automated decision making. Another project is exploring the challenges faces by tiny legal systems (those serving populations of fewer than 100,000 people). He has a long-standing interest in the role and design of top-level courts, editing and contributing to Building the UK's New Supreme Court: National and Comparative Perspectives (OUP 2004). He has written widely on aspects of administrative justice and judicial review. He is a co-author of de Smith’s Judicial Review (7th edn), the leading treatise on the subject in England and Wales. He is a co-investigator on the Nuffield Foundation-funded UKAJI project.
