Public Law: Text, Cases, and Materials (4th edn, May 2019)
With Maurice Sunkin and Jo Murkens, I write and edit an OUP textbook currently in its 4th edition. A 5th edition, taking fully into account the United Kingdom’s new relationship with the European Union after 31 December 2020, is in preparation. From a review of the first edition:
“In summary, with their new book Le Sueur, Sunkin and Murkens have successfully managed to accommodate the interests of lecturers and good students alike. The latter will have a highly accessible, readable and engaging account of Public Law served up in a student-friendly way, as well as a veritable mini-library of cases and materials etc. However, lecturers need rest assured that the book provides a really excellent account of the subject, notable for its breadth and depth of analysis, with the issues and controversies presented and discussed in a way that will challenge and stretch their best undergraduates.” (Ed Bates, Review in  Public Law 169)
As well as writing for law students, I am interested in how members of the public learn about the British constitution: see a blog post I wrote for UKCLA about Wikipedia’s role in public legal education.
