The Arc recently participated in an amicus brief before the Eighth Circuit Court of Appeals in the case Postawko v. Missouri Department of Corrections. Here, the plaintiffs filed a federal class action lawsuit in 2016 on behalf of Missouri prisoners seeking life-saving medical treatment while in prison, alleging that the Missouri Department of Corrections refuses to treat thousands of inmates with Hepatitis C in defiance of medical standards and in violation of the Americans with Disabilities Act. Class certification was granted in 2017 and defendants appealed. The Arc participated in a brief supporting class certification for plaintiffs and asserting the importance of class action lawsuits as an important tool for civil rights enforcement.
