The Moot: In the Inns of Court in 15th Century, moots were seen as a premier means to train lawyers. Law students would present their legal arguments to senior lawyers or judges as "practice" for a real Court appearance, but without damaging a client's interests!
Today, mooting in Law School is just as useful as its was in the 15th century. The Moot: known to strike fear in the hearts of law students, Counsel is required to stand on his or her feet (firmly!) and present their submissions to the Court. But beware the questioning judge, who expects a precise response to his or her cleverly worded question!
A successful moot requires two things. First, thorough preparation. Second, effective presentation.
