This document discusses human rights issues faced by prisoners with mental illness. It notes that the Supreme Court in India has ordered the release of prisoners held in psychiatric hospitals for longer than their potential sentence. Conditions in most prisons worldwide are poor, with overcrowding, corruption, abuse, lack of medical care and other issues. Many prisoners come from disadvantaged backgrounds and mental health can deteriorate in prison. The WHO and NHRC of India have made recommendations to improve treatment of mentally ill prisoners, such as ensuring psychiatric facilities and care in prisons, and not imprisoning those solely due to mental illness. Social workers can help safeguard prisoners' rights by linking them to support services and training on mental health issues.
