The Cartel and Criminal Practice Committee focuses on developments in criminal antitrust enforcement and keeps the Section membership informed on recent developments both in the U.S and abroad. We encourage active member participation through numerous opportunities ranging from networking events to providing CLE programs where enforcers and practitioners discuss interesting and topical ideas. We also encourage members to share their ideas during periodic Committee meetings.

The Cartel and Criminal Practice Committee offers members the chance to become active in the New York Antitrust Bar through program planning, speaking and writing opportunities. More importantly, the Committee provides a platform for its members to develop relationships with fellow antitrust practitioners working in all sectors, including defense, plaintiffs, government, and in-house attorneys. We encourage those who are interested in antitrust law to reach out to the Committee leadership to learn more about joining our group.
