Current Legal Problems was established after the Second World War as a series of public lectures on law. It is now regarded as the most significant series in the United Kingdom. Each year edited texts are reproduced in the form of a volume. This year's is the 53rd such volume. The range of subject-matter as ever is wide. Subjects explored this year include comparative law, legal theory, environmental law, restitution, IP law, family law, world trade law, and international law. Amongst the contributors to this volume are Lord Bingham, Joseph Raz, Jospeh Weiler, and Peter Birks. A companion volume containing the proceedings of UCL's annual inter-disciplinary colloquium is published each year under the umbrella title Current Legal Issues.
