MURDER WOUND WITH INTENT TO MURDER JUDGE ALONE TRIAL DEFENCE OF MENTAL ILLNESS SPECIAL VERDICT

Citation: R v Heydari [2015] NSWSC 207
Court: Supreme Court of New South Wales
Date: 25 March 2015
Judge(s): Mathews AJ

Background

The accused, an Afghan national who had arrived in Australia by boat in 2013, was living in a shared apartment in Berala, western Sydney, after being granted a conditional visa. He had recently moved in with a distant relative and another man, both of whom he had met on arrival in Sydney. By early September 2013 he had been experiencing significant mental health difficulties, including insomnia, depressed mood, and panic attacks, for which he had sought medical treatment.

In the early hours of 5 September 2013, the accused entered the bedroom where the two men were sleeping and stabbed both of them with a kitchen knife. One man died from a single stab wound to the chest that penetrated the lung and heart. The other sustained a life-threatening abdominal wound but survived after surgery. The accused admitted both stabbings and admitted he had intended to kill both men. He told police he acted because he believed the two men had raped him in his sleep and were planning to do so again, though the evidence established no such assault ever occurred.

The trial proceeded before the judge alone, by consent, on documentary material only. Both the prosecution and defence agreed, on the basis of psychiatric evidence, that a not guilty verdict on the ground of mental illness was the appropriate outcome on both charges.

  • Whether the accused was suffering from a "disease of the mind" within the meaning of the McNaghten rules at the time of the offences.
  • Whether, as a result of that disease of the mind, the accused did not know that what he was doing was morally wrong.
  • Whether the special verdict of not guilty on the ground of mental illness should be entered on both charges of murder and wounding with intent to murder.

Decision

The court first confirmed that the essential elements of both charges were established beyond reasonable doubt. The accused had inflicted the fatal wounds on the deceased, had seriously wounded the victim, and had admitted intending to kill both men. The only remaining question on each charge was whether the defence of mental illness was made out.

Both psychiatric experts agreed that at the time of the offences the accused was suffering from severe depression with psychotic features. One expert also diagnosed schizophrenia, though the court found it unnecessary to resolve that disagreement. Either way, the accused was suffering from a condition that constituted a "disease of the mind" within the McNaghten rules.

The court found that the accused's paranoid delusion that he had been sexually assaulted formed a direct product of his mental illness. That delusion caused him to believe he was morally entitled to kill the two men in retaliation. Applying the test from The King v Porter, the relevant question was not whether the accused knew his actions were illegal, but whether he retained the capacity to reason calmly about the moral quality of what he was doing. The court was satisfied he did not.

On that basis, the court entered a verdict of not guilty on the ground of mental illness on both charges. The accused was remanded in custody with orders made for a report on his care, treatment, and recommended placement in a prison or mental health facility.

Orders Made

  • Verdict of not guilty on the ground of mental illness entered on both the murder charge and the charge of wounding with intent to murder.
  • Proceedings adjourned to 26 June 2015.
  • Orders made for the accused's disposition in custody in the interim.
  • Orders made for a report to be provided to the court by the adjourned date, containing recommendations as to the care, treatment, and placement of the accused.

Key Takeaways

  • The McNaghten rules, as applied in New South Wales, require the defence to prove on the balance of probabilities that the accused was suffering from a disease of the mind that prevented him from knowing the moral quality of his actions at the time of the offence.
  • Severe depression with psychotic features was accepted by the Supreme Court as constituting a "disease of the mind" within the McNaghten rules.
  • The test for the mental illness defence is not whether the accused knew the act was illegal, but whether he retained the capacity to reason, with a moderate degree of calmness, about the moral quality of what he was doing (following The King v Porter (1933) 55 CLR 182).
  • A delusional belief, even one that is genuinely held, does not justify or excuse conduct in law, but it can form the basis for a finding that the accused lacked the relevant moral understanding required to defeat the mental illness defence.
  • Where both parties agree that a not guilty verdict on the ground of mental illness is appropriate, and the psychiatric evidence supports that position, the court will examine the evidence independently before entering the special verdict.
