To consider to what extent and on what criteria the law should recognise mental disorder or abnormality in a person accused of a criminal offence as a factor affecting his or her liability to be tried or convicted. 2. To consider whether there is any need for the continuance of the power in s 662 of the Criminal Code to impose an indeterminate sentence on a convicted person simply on the grounds of his or her 'mental disorder'. 3. To consider what procedures should be provided for reviewing the situation of persons who have been ordered to be detained or kept in custody because of their mental condition by orders made under ss 631, 652, 653, 662 or 693(4) of the Criminal Code, with a view to determining whether their detention or custody can be terminated. Such procedure should provide for review by way of administrative routine as well as at the request of the person detained or kept in custody. 4. To consider whether it is desirable for there to be a judicial investigation as to the guilt or innocence of an accused person notwithstanding that he or she has been found to be of unsound mind and ordered to be kept in custody pursuant to ss 631 or 652 of the Criminal Code, or admitted to an approved hospital consequent on an order made under s 36(2) of the Mental Health Act 1962. 5. To consider whether courts of summary jurisdiction require any powers beyond those in s 36 of the Mental Health Act 1962 to permit them to deal fully with accused persons who come before them suffering from mental disorder; in particular to consider whether they require powers analogous to those in ss 631, 652 and 653 of the Criminal Code. Chapter 1 / 2 6. To consider whether it is desirable that the prosecution and defence should be obliged to exchange, before trial, all expert reports relating to the mental condition of the accused person which are intended to form the basis of evidence to be adduced at the trial, and if that is thought to be desirable, to propose appropriate rules for the enforcement of that obligation. 7. To consider whether the courts should have power to obtain psychiatric reports, and if so, for what purpose, and in what circumstances, and by what procedure. 8. To review Division 6 of Part IV of the Mental Health Act 1962 (which deals with security patients) and its relationship to s 34C of the Offenders Probation and Parole Act 1963. Chapter 2 INTRODUCTION 1. SCOPE OF THE PAPER 2.1 The courts have for many centuries been confronted with people who have committed offences while mentally disordered or who are mentally disordered at the time of the trial, and rules and procedures for dealing with such people have gradually been developed. One response to such people was the development of the insanity defence. Insanity is not a psychiatric term. It is a legal term meant to encompass those persons who are so mentally disordered at the time of committing an offence that they should not be held responsible for their actions. The insanity defence developed with a movement of the criminal law from a basis of strict liability to one in which fault or moral blame-worthiness became an element of many offences. 2.2 In recent years various people have criticised the insanity defence and have proposed that it be abolished. Others, while accepting the need for such a defence, have criticised its formulation.
