A legal case brief is a written summary of a legal case that features all of the important parts of the case. Briefing a case is the act of creating a “brief” summary of the case, including the facts, issues, laws, and reasoning of a case. Briefing a legal case fosters understanding of the case, the legal issues in the case and the reasons why a court ultimately decided the case the way it was decided. Simply put, briefing a case helps one to understand the case, and the law.
