Citation: R v Gregory John Thompson [2017] NSWSC 628
Court: Supreme Court of New South Wales
Date: 18 May 2017
Judge(s): Hamill J

Background

The offender, a man in his early fifties, was convicted by jury of the murder of his ex-wife's new partner at the victim's home in Cessnock in the early hours of 1 March 2015. The offender and his ex-wife had been married for approximately 30 years and had four children together. Their divorce was finalised just weeks before the killing.

In the period leading up to the murder, the offender engaged in escalating conduct directed at his ex-wife, including threatening text messages and following her by car. On 27 February 2015, an apprehended violence order (AVO) was made against him. He was arrested the following day for an alleged breach of the AVO, interviewed by police, and released on bail. During that process, he learned the name of the victim.

Within 24 hours of his release, the offender used a phone book to locate the victim's address, purchased items to facilitate a planned suicide by carbon monoxide, armed himself with two kitchen knives, and attended the victim's home after midnight. He entered the premises and fatally stabbed the victim multiple times. The offender attempted suicide after the killing but survived. At trial, the jury rejected a defence of substantial impairment by reason of abnormality of mind (a partial defence that, if accepted, would have reduced the conviction to manslaughter).

  • What is the appropriate sentence for murder, taking into account the standard non-parole period of 20 years and all relevant objective and subjective factors?
  • What weight should be given to the offender's psychiatric condition, specifically major depressive illness, in circumstances where the jury rejected the substantial impairment defence?
  • How should general deterrence be balanced against the offender's mental illness and the domestic-violence context of the offending?
  • What relevance do victim impact statements from the victim's family have to the sentencing exercise?
  • How should planning, breach of an AVO, breach of bail, and the vulnerability of the victim affect the assessment of objective seriousness?

Decision

Hamill J assessed the offending as falling in the upper-middle to serious range of objective gravity for murder. The victim was killed in his own home, unarmed and defenceless. The offender had planned the attack over the course of the day before the killing, breached both his AVO and his bail conditions, removed his footwear to avoid detection as he approached, and carried two knives. His motive was jealousy and an obsessive refusal to accept that his marriage had ended. The court found that the offender had an intent to kill.

On the psychiatric evidence, the court accepted that the offender suffered from a major depressive illness that was causally connected to his behaviour, including his obsessive and jealous conduct. While the jury's rejection of the substantial impairment defence meant the illness did not operate to reduce the crime to manslaughter, the court accepted that the illness was nonetheless relevant to sentencing. It moderated the weight given to general deterrence, on the basis that a person acting under the influence of a significant psychiatric condition is a less appropriate vehicle for deterrence-based punishment than an offender acting from purely calculated motives.

The court gave considerable weight to denunciation and just punishment. The harm to the victim's family was described as devastating, and victim impact material was considered under the relevant statutory framework. The court also noted that the circumstances of the offence arose in a domestic violence setting, which the High Court in Munda v Western Australia has recognised as warranting serious condemnation.

Against those aggravating factors, the court weighed the offender's lack of prior convictions, his psychiatric illness, his attempt to take his own life after the killing (which Hamill J accepted as a relevant, if limited, mitigating indicator), and the prospect of rehabilitation. Applying the instinctive synthesis required by Muldrock, the court sentenced the offender to a non-parole period of 14 years and 3 months, with a total sentence of 20 years.

Orders Made

  • Total sentence of 20 years imprisonment for murder.
  • Non-parole period of 14 years and 3 months.
  • Sentence backdated to commence from the date of the offender's arrest (consistent with time already served in custody).
  • Balance of term of 5 years and 9 months, expiring 30 June 2038.
  • Recommendation that the offender receive timely and frequent psychiatric treatment and medication in accordance with the psychiatrist's recommendations, and that relevant psychiatric reports be provided to the Department of Corrective Services.

Key Takeaways

  • A jury's rejection of a substantial impairment defence does not eliminate a psychiatric condition from the sentencing calculus. Hamill J found that major depressive illness, even where it did not reduce the offence to manslaughter, remained relevant to the weight given to general deterrence.

  • Planning, breach of an AVO, breach of bail conditions, and the vulnerability of a defenceless victim in his own home are all significant aggravating factors in assessing objective seriousness for murder.

  • The Supreme Court applied the High Court's approach in Muldrock, treating the standard non-parole period of 20 years as an important legislative yardstick rather than a starting point, and conducting an instinctive synthesis of all relevant factors.

  • Domestic violence murder warrants strong denunciation. The court drew on Munda v Western Australia for the proposition that offences committed in a domestic violence context call for serious condemnation by the sentencing court.

  • Where an offender has no prior criminal history and the circumstances giving rise to the offending are unlikely to recur, community protection carries less weight in the sentencing balance, though punishment, accountability, and denunciation remain central.
