1) n. a written legal argument, usually in a format prescribed by the courts, stating the legal reasons for the suit based on statutes, regulations, case precedents, legal texts, and reasoning applied to facts in the particular situation. A brief is submitted to lay out the argument for various petitions and motions before the court (sometimes called "points and authorities"), to counter the arguments of opposing lawyers, and to provide the judge or judges with reasons to rule in favor of the party represented by the brief writer. Occasionally on minor or follow-up legal issues, the judge will specify that a letter or memorandum brief will be sufficient. On appeals and certain other major arguments, the brief is bound with color-coded covers stipulated in state and/or federal court rules. Ironically, although the term was originally intended to mean a brief or summary argument (shorter than an oral presentation), legal briefs are quite often notoriously long. 2) v. to summarize a precedent case or lay out in writing a legal argument. Attentive law students "brief" each case in their casebooks, which means extracting the rule of law, the reasoning (rationale), the essential facts, and the outcome. 3) v. to give a summary of important information to another person.
