"This is the second and final report addressing people with cognitive and mental impairments and the criminal justice system. The first report (Report 135) was issued in June 2012 ... The focus of this report, broadly speaking, is on the law relating to people with mental health and/or cognitive impairments who have committed serious offences. We consider fitness to plead, the defence of mental illness, substantial impairment, and infanticide. We also examine the procedures that follow a finding of unfitness or not guilty by reason of mental illness (NGMI), and the management of people who become forensic patients. Further, we consider issues relating to apprehended violence orders against people who have cognitive and/or mental health impairments. We also deal with the retention and destruction of forensic samples taken from people who are diverted, who are found NGMI, or who are unfit and not acquitted at a special hearing (UNA)."--Executive summary.
