Delaware Solitary Confinement Case

Led the Pepper Hamilton team that served as pro bono co-counsel with the American Civil Liberties Union of Delaware (ACLU) and Community Legal Aid Society, Inc. (CLASI) in bringing claims on behalf of mentally ill inmates being held in solitary confinement by the Delaware Department of Correction. The case resulted in a successful settlement on behalf of the inmates, including improved conditions and mental health treatment services. In recognition of its efforts, the Pepper Hamilton team received a number of awards in 2016-2017, including the ACLU’s Clarence Darrow Award, CLASI’s Founder’s Award, the National Disability Rights Network (NDRN) Advocacy Award, and the Delaware State Bar Association’s Christopher W. White Distinguished Access to Justice Leadership Award.
