On September 29, 2010, the State of Illinois entered into a Consent Decree, settling the Williams v Quinn class action lawsuit, first filed in 2005. The lawsuit alleged that Illinois was in violation of Title II of the American with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act by “needlessly segregating” Plaintiffs, a class of 4,500 Illinois residents with Serious Mental Illness (SMI) living in institutional settings (Institutes of Mental Disease ), and denying them opportunities to receive services in more integrated settings.
