Citation: R v McGarrity [2000] NSWSC 1080
Court: Supreme Court of New South Wales (Common Law Division)
Date: 23 November 2000
Judge(s): Barr J
Background
The accused faced three charges arising from events between 27 and 30 January 2000 at San Remo, NSW: the murder of a four-year-old child, sexual assault of the child's mother without consent, and malicious infliction of grievous bodily harm upon the same woman. The accused elected for trial by judge alone, with the Crown's consent, and admitted the acts underlying all three charges.
The accused had a lengthy psychiatric history marked by escalating delusional beliefs, including that he was Jesus Christ and Nostradamus, and that he possessed healing powers. He had been involuntarily admitted to a psychiatric clinic on more than one occasion and carried a diagnosis of bipolar affective disorder and/or schizo-affective disorder. In the weeks before the offences, he engaged in increasingly bizarre and dangerous behaviour in the home he shared with the victims, including rituals, the setting up of shrines, and cruelty towards the child, whom he believed was an alien possessed by the spirit of her dead father.
The sole issue at trial was whether the accused was mentally ill at the time of the offences such that he bore no legal responsibility for his actions.
Legal Issues
- Whether the accused satisfied the mental illness defence, derived from the M'Naghten rules, at the time he committed the charged acts.
- What orders should follow a finding of not guilty on the ground of mental illness, including the regime governing the accused's ongoing detention and potential future release.
Decision
Barr J applied the established test for the mental illness defence, which asks whether the accused, at the time of the offences, was suffering from a defect of reason caused by a disease of the mind such that he either did not know the nature and quality of his acts, or did not know that what he was doing was wrong. The Australian formulation adds that if a disordered mind prevented the accused from reasoning about the moral quality of the act with any moderate degree of sense and composure, the defence is made out.
The court was satisfied, on the balance of probabilities (the standard the accused was required to meet), that his mental illness at the time of the offences was such that he could not appreciate the wrongness of his actions. His long psychiatric history, his deeply held delusional beliefs, his hearing of voices, and the extreme and irrational nature of his conduct in the period immediately before and during the offences all supported this conclusion.
Following the finding, the court explained in detail the statutory regime governing forensic patients. The accused would be detained in a psychiatric institution, subject to periodic reviews by the Mental Health Review Tribunal. Any release, whether conditional or unconditional, would require satisfaction that the safety of the accused and the public would not be seriously endangered. A conditional release could be revoked and the accused redetained if any conditions were breached.
Orders Made
- The accused is found not guilty of all three charges by reason of mental illness.
- The accused is to be detained in a hospital until released by due process of law.
Key Takeaways
- The mental illness defence in NSW requires the accused to establish, on the balance of probabilities, that a disease of the mind at the time of the offence prevented them from knowing the nature of their act or knowing it was wrong, or from reasoning about its moral quality with any moderate degree of composure.
- Admission of the underlying acts does not preclude a successful mental illness defence; the contest in such cases turns entirely on the accused's mental state at the relevant time.
- A finding of not guilty on the ground of mental illness does not result in unconditional release. The Supreme Court ordered indefinite detention in a hospital, subject to a structured statutory regime of review and supervised release.
- Under that regime, the Mental Health Review Tribunal cannot recommend release unless satisfied that neither the accused nor any member of the public would be seriously endangered. Any recommendation must then proceed through the Department of Health to the Governor-in-Council.
- Conditions that can be attached to any supervised release include requirements as to residence and medication, and a breach of conditions can lead to redetention.
