This revised edition of an established professional responsibility casebook is designed to be teachable and versatile. New teachers and adjuncts will appreciate the extensive instructor support (including a detailed teacher's manual with suggestions for classroom presentation), while seasoned teachers will find the materials to be contemporary, intellectually challenging and provocative. The text caters to the needs of students who will enter a broad range of practice environments, from small-firm or solo work to large-firm practice. Problems at the end of each chapter, taken from current cases and news stories, incorporate cutting-edge issues and create possibilities for enrichment and expansion in areas of the instructor’s interest. The second edition adds material addressing the professional responsibility implications of new technologies and updates the rules and materials relating to mobile lawyers and imputed disqualification.
