The basic structure of a moot court competition roughly parallels what would happen in actual appellate practice. Participants will typically receive a problem ahead of time, which includes the facts of the underlying case, and often an opinion from a lower court that is being challenged in the problem. Students must then research and prepare for that case as if they were lawyers or advocates for one or sometimes both of the parties. Depending on the competition, participants will be required to submit written briefs, participate in oral argument, or both. The case or problem is often one of current interest, sometimes mimicking an actual case, and sometimes fabricated to address difficult legal issues.
