Moot refers to an issue that remains unsettled, open to argument or debatable. It is especially refers to a legal question which has not been determined by any decision of any court. In the mid-19th century people also began to use the term moot to mean “of no significance or relevance.” Thus, a moot point, however debatable, is one that has no practical value.
Many law schools have students participate in moot court competitions. The moot courts provide students training in written and oral advocacy, by giving students mock problems involving current "real world" legal issues, and then requiring the students to argue the cases to appellate courts. Moot courts aim to teach law students the techniques and processes real lawyers will need.
