Chepiga also maintains a significant pro bono practice. Among other cases, he represented a class of individuals with mental disabilities residing in so-called adult homes in New York City. The class sued the state of New York, claiming that these homes violated the “integration mandate” of the Americans with Disabilities Act (ADA). After ten years of litigation, the parties reached a landmark settlement to end the state’s decades-long discrimination.
Chepiga serves on several non-profit boards, including the Cyrus R. Vance Center for International Justice, the Mt. Sinai Medical Legal Partnership, the French American Foundation, the Quogue Library, and the New York Lawyers for the Public Interest Pro Bono Advisory Council (PBAC).
Chepiga is also the co-author of “Ownership or Use? Civilian Property Interests in International Humanitarian Law,” which appeared in the 49th volume of Harvard International Law Journal in 2008.
