The fourth edition of this popular text continues the tradition of using problems to help students identify professional responsibility issues, then providing references to the relevant Model Rules and excerpts from reported cases, ethics committee opinions, law review and bar journal articles, and other secondary sources. The approach is comprehensive, with discussions of all of the Model Rules and most of the Model Code of Judicial Conduct, including new provisions of both sets of rules adopted since the third edition of the text. The text is still a reasonable size (600 pages), allowing instructors to cover the entire book in a three hour class.
