Supreme Court 13 July 2007

R v Zaro

[2007] NSWSC 756

Homicide
CRIMINAL LAW SENTENCE CONVICTION OF MURDER AFTER TRIAL.

Citation: R v Zaro [2007] NSWSC 756
Court: Supreme Court of New South Wales
Date: 13 July 2007
Judge(s): Howie J

Background

On 17 April 2004, an 18-year-old offender fatally stabbed a close friend of the same age during a late-night gathering at the deceased's home. The two had been friends since school and there was no prior enmity between them. The evening had involved substantial alcohol consumption by those present.

In the hours leading up to the stabbing, the offender had become increasingly agitated and physically aggressive toward the deceased, placing him in chokehold positions on multiple occasions. Two younger friends attempted to intervene but were pushed away. The offender then retrieved a knife from the kitchen and stabbed the deceased.

On 24 May 2007, a jury convicted the offender of murder following a trial. The central contested issues at trial were whether the offender was mentally ill at the time, whether he lacked the requisite intent due to intoxication, and whether he was guilty only of manslaughter on the basis of substantial impairment.

  • Whether the offender was mentally ill at the time of the stabbing under the M'Naghten rules, so as to establish a complete defence
  • Whether the offender's intoxication negated the intent required for murder
  • Whether the offender was guilty only of manslaughter by reason of substantial impairment under section 23A of the Crimes Act 1900
  • What sentence was appropriate for murder, having regard to the offender's youth, the objective seriousness of the offence, and other subjective factors

Decision

The jury rejected all three defences raised at trial. Although a psychologist gave evidence supporting the mental illness defence, and the killing was described as bizarre in nature, the jury was not satisfied on the balance of probabilities that the offender met the M'Naghten test. The substantial impairment defence also failed, as the section required the jury to disregard intoxication when assessing abnormality of mind, and little other evidence supported that defence.

Howie J proceeded to sentence on the basis that the offence was above the midrange of objective seriousness, given the sustained and escalating violence, the use of a knife retrieved during the attack, and the complete vulnerability of the deceased at the time of the fatal blow. The court characterised the killing as heartless, wicked, and selfish.

In mitigation, the court gave considerable weight to the offender's youth. The offender was 18 at the time of the offence and had no prior criminal history. He had adapted well to Australian society despite earlier difficulties, and there was evidence of genuine prospects for rehabilitation. Howie J departed downward from the standard non-parole period on account of these subjective factors, while noting that the overall sentence length had to remain sufficient to address any post-release support needs.

The court acknowledged the profound grief of the deceased's family but made clear that the sentencing exercise is not one of retaliation. It expressed the view that the offender, when eventually released, could still contribute meaningfully to the community.

Orders Made

  • Non-parole period of 16 years and 6 months, commencing 18 April 2004 and expiring 17 October 2020
  • Balance of term of 5 years and 6 months, commencing 18 October 2020 and expiring 17 April 2026

Key Takeaways

  • The Supreme Court departed downward from the standard non-parole period for murder where the offender's youth and strong prospects for rehabilitation warranted considerable mitigation, even though the objective seriousness of the offence exceeded the midrange.
  • A jury's rejection of the mental illness defence can stand even against expert evidence, where the jury is not satisfied on the balance of probabilities that the M'Naghten test is met.
  • Under section 23A of the Crimes Act 1900, a jury assessing the substantial impairment defence must disregard the effects of intoxication when determining whether an abnormality of mind was present.
  • Youth is generally given greater weight in setting the non-parole period than in determining the head sentence, reflecting the court's flexibility in assessing the period required for the offender to demonstrate readiness for release.
  • Sentencing for murder does not seek to replicate the loss suffered by the victim's family; the court's role is to impose a sentence that is proportionate and that supports the offender's eventual reintegration.
