What it does
The Criminal Justice (Mental Impairment) Act 1999 establishes the legal framework in Tasmania for dealing with defendants whose mental processes are disordered or impaired and who are therefore unfit to stand trial, or who are found not guilty by reason of insanity (or the equivalent finding). It applies to all courts in Tasmania (section 4(1)) and extends to restriction orders and supervision orders made under the Sentencing Act 1997 (section 4(2)). The Act creates a structured pathway from the point at which a defendant's fitness to stand trial is raised, through investigation and determination by the court, to the making of one of a set of legally available orders. It also governs the ongoing supervision, review, variation, and discharge of those orders. The Act does not create new criminal offences or prescribe penalties for the underlying conduct; instead it provides the procedure and disposition options that apply once a mental impairment issue is properly before a court. The Act addresses two distinct but related scenarios: first, a defendant who is currently unfit to stand trial (Part 2, sections 8 to 20), and second, a defendant who has been found not guilty by reason of insanity at trial (Part 3, section 21). In both situations the court may make a restriction order (detention in a secure mental health unit), a supervision order (community release under supervision), a treatment order under the Mental Health Act 2013, release on conditions, or unconditional release. Only the Supreme Court may make a restriction order or a supervision order (sections 18(3) and 21(2)). The Act also provides for special hearings for defendants who are unlikely to become fit within 12 months, breach of conditions on release, forensic order review by the Tasmanian Civil and Administrative Tribunal, appeals to the Court of Criminal Appeal, and the apprehension of defendants who contravene supervision orders. The guiding principle is that restrictions on a defendant's freedom and personal autonomy should be kept to the minimum consistent with the safety of the community (section 34).
