This comprehensive volume on professional ethics gives you current information from a variety of sources. It is effectively organized around the American Bar Association's Model Rules, which many states have adopted, and the ABA's Judicial Code.
This reference combines Rotunda and Dzienkowski's thorough understanding of the current ethical climate, with the authors' all-encompassing commentary and discussions, and references to the American Law Institute's new Restatement of the Law, 3dLaw Governing Lawyers. It also contains up-to-date case law references.
