Welcome to Hansberry Competition

Hansberry Competition provides advice and representation in complex competition cases, with an emphasis on cartels. Our services run from working on all phases of an investigation to litigation. We conduct audits and competition compliance training for our clients. Ms. Hansberry-Biegunska, the head and founder of the firm, is as adept at working with competition authorities and leniency applicants as she is in defending cartel cases and bringing plaintiff damage cases. She also counsels and provides training on litigation strategy and practice.
