Citation: Regina v Scott Ashley Simpson [2004] NSWSC 233
Court: NSW Supreme Court, Common Law Division
Date: 31 March 2004
Judge(s): Bell J
Background
The accused was charged with the murder of a fellow inmate at the Metropolitan Reception and Remand Centre (MRRC) in Silverwater on 30 March 2002. He had a documented history of psychotic episodes dating back to at least September 2001, including hospitalisations, erratic and violent behaviour, and persistent delusional beliefs that various agencies (including ASIO, the CIA, and the NCA) were surveilling or persecuting him.
In the months before the killing, the accused had come to the attention of police and health services on multiple occasions. He had been admitted to psychiatric facilities, made threats against family members and a housemate, assaulted persons in apparently unprovoked incidents, and was noted by custodial staff as someone who could "snap at any moment." The morning of the offence, he was placed in a cell at the MRRC following an assault the previous day.
The accused elected to be tried by judge alone under section 132 of the Criminal Procedure Act 1986 (NSW), with the Director of Public Prosecutions consenting. He entered a plea of not guilty on the basis that he was mentally ill at the time of the offence, which framed the central issue at trial.
Legal Issues
- Whether the accused was mentally ill at the time of the killing within the meaning of the mental illness defence at common law
- Whether the accused suffered from a disease of the mind that deprived him of the capacity to reason with moderate sense and composure about the wrongness of his conduct
- What findings and orders were available under the Mental Health (Criminal Procedure) Act 1990 (NSW) following a special verdict of not guilty by reason of mental illness
Decision
Three forensic psychiatrists gave evidence, and their opinions were unanimous: the accused was, in all likelihood, suffering from an acute psychotic mental illness at the time he killed the deceased. Bell J found nothing in the evidence to cast doubt on that expert opinion, and described the broader factual record as consistent with it.
The court was satisfied on the balance of probabilities that the accused was suffering from paranoid schizophrenia at the time of the offence. The court was further satisfied that this condition prevented the accused from reasoning with a moderate degree of sense and composure that his acts, repeatedly striking the deceased about the head with his hands and feet, were wrong. This satisfied the elements of the mental illness defence.
Bell J returned a special verdict of not guilty by reason of mental illness pursuant to section 39 of the Mental Health (Criminal Procedure) Act 1990. Before doing so, the court addressed the requirements of section 37 of that Act, which directs a trial judge (sitting alone in place of a jury) to consider and explain the possible findings, their legal and practical consequences, and the role of the Mental Health Review Tribunal in supervising forensic patients.
Orders Made
- The accused was found not guilty of the murder of the deceased by reason of mental illness.
- The accused was ordered to be detained in strict custody in a correctional centre within the meaning of the Crimes (Administration of Sentences) Act 1999, or such other place as may be determined by the Mental Health Review Tribunal, until released by due process of law.
Key Takeaways
- Bell J confirmed that the mental illness defence requires satisfaction, on the balance of probabilities, that a disease of the mind prevented the accused from reasoning with moderate sense and composure about the wrongness of their conduct.
- Unanimous expert psychiatric opinion, unchallenged and consistent with the broader evidentiary record, was sufficient to establish the mental illness defence to the required standard.
- Where an accused elects trial by judge alone in a mental illness case, the trial judge must still work through the obligations imposed by section 37 of the Mental Health (Criminal Procedure) Act 1990, including consideration of the Mental Health Review Tribunal's role and powers.
- A special verdict of not guilty by reason of mental illness does not result in unconditional release; the accused is ordered into strict custody, with any future release determined by due process through the Mental Health Review Tribunal.
- The decision illustrates how a pattern of documented psychotic episodes, hospitalisations, and erratic behaviour in the period leading up to an offence can form part of the evidentiary foundation supporting a mental illness defence at trial.
