This book of essays,the product of a conference held at the University of Birmingham in the spring of 1998, contains contributions from a group of extremely distinguished scholars in the fields of both public and private law. The meaning of proportionality is examined in a number of different contexts, including those of EC law, the domestic law of the Member States of the EU and the law of the European Convention on Human Rights. Its substantive content and procedural implications are analysed and contrasted, in particular, with the concept of Wednesbury unreasonableness. Its use in criminal and anti-discrimination law is also examined, as is its future likely impact in the UK after incorporation of the European Convention.Contributors: Paul Craig, Evelyn Ellis, David Feldman, Nicholas Green QC, Lord Hoffmann, Francis G. Jacobs, Jeremy McBride, Takis Tridimas, Walter van Gerven.
