Coordinated by the Justice in Mexico program at the University of San Diego, the Oral Adversarial Skill-Building Immersion Seminar (OASIS) program is an oral advocacy training program that provides skill building and exchange opportunities. This program is currently funded by the State Department as part of the Mérida Initiative to foster closer ties between U.S. and Mexican faculty and legal experts working to improve the functioning of the Mexican criminal justice system by providing training to law faculty and students at Mexico’s largest public universities. OASIS has three specific objectives that will continue to guide Justice in Mexico’s efforts during the next two years: 1) provide three 40-hour litigation workshops to law professors and students 2) provide three training/study tours to the United States 3) provide one international symposium on oral, adversarial, accusatory criminal justice systems, Mexico’s criminal justice reforms, and the role law schools will play in the transition to this new criminal justice system.
