The Jessup International Law Moot Court Competition is the world's largest moot court competition, with participants from over 600 law schools in more than 90 countries. The competition is a simulation of a fictional dispute between countries before the International Court of Justice, the judicial organ of the United Nations. A team from each participating school is required to prepare oral and written pleadings arguing both the applicant and respondent positions of the case.

The hypothetical fact pattern is released in mid-September, and the written pleadings are usually due in early to mid-January. Oral arguments will first be held at the regional level in New York City in February 2018. Finalist teams from the regional competition will advance to the International Rounds held in Washington, D.C., in March 2018, where they will compete against Jessup teams from around the world.

Students are eligible for two credits if selected for the Jessup team, and serving on the team may also satisfy the Legal Writing Requirement. As such, participation on the Jessup team requires a substantial time commitment, both to prepare the written pleadings in the fall semester and to prepare and practice for oral argument in January and February of the spring semester.
