The American Law Institute (ALI) publishes Restatements of the Law to both restate what the law is and to shape the development of the law. The Restatement contains black letter law followed by commentary and examples. Researchers should consult the law of the state in which they are researching to determine the authority their state gives to this Restatement.
Note that Restatement of the Law Third, The Law Governing Lawyers represents the first time that the ALI has drafted and published a Restatement addressing issues of ethics and professional responsibility, therefore there is no First or Second series for this title.
