What is the Jessup?

Jessup is the world's largest moot court competition, with participants from roughly 700 law schools in 100 countries and jurisdictions. The Competition is a simulation of a fictional dispute between countries before the International Court of Justice, the judicial organ of the United Nations. One team is allowed to participate from every eligible school. Teams prepare oral and written pleadings arguing both the applicant and respondent positions of the case.

Jessup 2023

The Jessup 2023 Competition concerns the interpretation of a peace treaty, deadly attacks in allegedly occupied territory, unilateral economic sanctions, and the legal consequences of failing to dispose of hazardous waste properly.
