A brief is a legal document prepared by a party to the Court. It contains information on the facts of the case, the legal issues to be decided, the law the Court ought to apply, and the decision the party desires the Court to reach.
The goal of a brief is to convince the Court that one's position is correct, logical and reasonable. To be compelling, a brief must also be understandable and concise. The Court will read many briefs throughout the session, so it is important to write in a clear and interesting manner.
