Moot court is a co-curricular activity at many law schools. Participants take part in simulated court or arbitration proceedings, usually involving drafting memorials or memoranda and participating in oral argument. In many countries, the phrase "moot court" may be shortened to simply "moot" or "mooting". Participants are either referred to as "mooters" or, less conventionally, "mooties". Moot court involves simulated proceedings before an appellate court, arbitral tribunal, or international dispute resolution body. These are different from mock trials that involve simulated jury trials or bench trials. Moot court does not involve actual testimony by witnesses, cross-examination, or the presentation of evidence, but is focused solely on the application of the law to a common set of evidentiary assumptions, facts, and clarifications/corrections to which the competitors are introduced. Though not moots in the traditional sense, alternative dispute resolution competitions focusing on mediation and negotiation have also branded themselves as moot competitions in recent times, as had role-playing competitions in the past such as the Jean-Pictet. Moot court, like law review and clinical work, is one of the key extracurricular activities in many law schools around the world. Depending on the competition, students may spend a semester researching and writing the written submissions or memorials, and another semester practicing their oral arguments, or may prepare both within the span of a few weeks. Whereas domestic moot court competitions tend to focus on municipal law such as criminal law or contract law, regional and international moot competitions tend to focus on cross-border subjects such as EU Law, public international law (including its subsets environmental law, space law, and aviation law), international human rights law, international humanitarian law, international criminal law, international trade law, international maritime law, international commercial arbitration, and foreign direct investment arbitration.
