Inmates in solitary confinement are 33% more likely to commit suicide than other inmates. California judge agrees with plaintiffs: "the consistent dearth of SLIs (sign-language interpreters) when psychiatric technicians take their rounds for patients housed in solitary, known as administrative segregation housing units" means those with disabilities cannot communicate with their evaluators. "SLIs are also absent during education and vocational programs at the Substance Abuse Treatment Facility." U.S. District Judge Claudia Wilken insisted Tuesday that the state must quickly put the sign-language interpreters (SLIs) in place. She said there is "clear" and "convincing" evidence that the corrections department has not complied with the court-ordered plan and is still in violation of the ADA. Sign language interpreters must be present in the solitary unit when technicians evaluate the mental health status of inmates, according to the ruling.
