The Centre for European Legal Studies (CELS) at the Faculty of Law, University of Cambridge, runs a series of lunchtime seminars during the Michaelmas and Lent Terms. These seminars provide a platform for the presentation of new ideas by leading scholars from inside and outside the University. The lunchtime seminars address topical issues of European Union Law and Comparative Law, with a view to using collective debate as a forum for developing and disseminating ideas, and producing high quality research publications which contribute to an understanding of major issues in the European Union. There is a close link between the CELS Lunchtime Seminar series and the Cambridge Yearbook of European Legal Studies (CYELS). Papers generated from most of these seminars are published as articles in the CYELS. Video recordings of the seminars are made available via podcast, and videos on YouTube (https://www.youtube.com/playlist?list=PLy4oXRK6xgzGUiTnOrTDiD0SfIbGj2W-x).
