Criminal law is subject to rapid changes, not only through statutory amendment but also by means of judical decisions. "Elliott and Wood's Casebook on Criminal Law" provides an extensive, authoritative collection of extracts from the leading cases and other vital materials. Judicial activity since publication of the further edition has transformed many of the chapters. Among the topics included in this edition are: the restatement of the meaning of intention in "Moloney" and "Hancock and Shankland"; the redefinition of the mental elements of murder in "Moloney" and of manslaughter in "Seymour" and "Kong Chenk Kwan"; and the meaning of appropriation in theft in "Morris". Attempt and impossiblity are reviewed through "Anderton v. Ryan" and "Shivpuri", as are claims of self-defence in "Beckford" and duress in "Howe". A further important development, the Law Commission's draft Criminal Code, is widely referred to throughout the detailed notes accompanying the materials.
