R v BT

[2017] NSWSC 1600

Homicide
CRIMINAL LAW SENTENCE MANSLAUGHTER KILLING BY FATHER OF INFANT CHILD

Citation: R v BT [2017] NSWSC 1600
Court: Supreme Court of New South Wales
Date: 24 November 2017
Judge(s): Hidden AJ

Background

The offender stood trial for the murder of his eight-week-old daughter in August 2014 at the family home in Regents Park. The jury acquitted him of murder but could not reach a verdict on the alternative charge of manslaughter. He subsequently pleaded guilty to manslaughter on the basis that he caused a substantial blunt-force impact to the back of the infant's head, producing a craniospinal injury that led to her death.

The agreed facts, accepted by both parties as the basis for sentencing, established that the offender had sole care of the baby for periods on the night in question. Medical evidence from a forensic pathologist and a neuropathologist confirmed the cause of death as a blunt-force craniospinal injury consistent with a significant impact to the back of the head. The offender had initially denied any knowledge of how the injuries occurred, and only at the time of his arrest in November 2015 claimed he had accidentally dropped the baby on a hard floor. His guilty plea did not attribute the death to that accidental drop.

The offender was 25 at the time of the offence and had a significant criminal history, including prior convictions for assault occasioning actual bodily harm against his partner, dishonesty offences, and robbery in company. A psychological report outlined a seriously troubled upbringing, including a violent and alcoholic mother, periods in foster care from age eight, and heavy cannabis use from his mid-teens.

  • What is the appropriate sentence for manslaughter of an infant child, where the offending was spontaneous but no other mitigating factor reducing objective gravity could be identified?
  • What weight should be given to a guilty plea entered after a trial concluded with an acquittal on murder and a hung jury on manslaughter?
  • How should prior criminal history, adverse personal circumstances, and prospects of rehabilitation be balanced in the sentencing exercise?
  • Whether special circumstances justified a departure from the standard ratio between non-parole period and total sentence.

Decision

Hidden AJ assessed the objective gravity of the offence as substantial. The offender was in a position of trust and responsibility as the infant's father and carer. While the conduct was accepted as spontaneous rather than premeditated, no other mitigating factor bearing on objective gravity could be identified.

On the subjective case, the court acknowledged the offender's deeply troubled upbringing as relevant context for his criminal history. His prospects of rehabilitation were considered genuine, supported by his period free of drugs and alcohol during custody and the assessment in the psychological report. Personal deterrence was therefore not the primary sentencing consideration, although general deterrence remained important given the nature of the offence.

The court reviewed comparable sentencing decisions involving the manslaughter of infant children, noting that sentences at first instance and on appeal ranged from six to nine years, with non-parole periods of three to four and a half years. Hidden AJ treated these decisions as useful reference points while recognising that each case turns on its own facts. A starting point of ten years' imprisonment was adopted, reduced by 20 per cent for the utilitarian value of the guilty plea to reach eight years.

Special circumstances were found to exist, warranting a longer-than-standard balance of term to support rehabilitation upon release. A non-parole period of five years was imposed. The sentence was not backdated to account for time served on the earlier assault convictions, as that earlier custody related to a distinct matter.

Orders Made

  • Non-parole period of 5 years, commencing 14 November 2015 and expiring 13 November 2020.
  • Balance of term of 3 years, commencing 14 November 2020 and expiring 13 November 2023.
  • Total sentence of 8 years' imprisonment.
  • Eligible for release on parole on 14 November 2020.

Key Takeaways

  • A guilty plea entered after a trial resulting in acquittal on the primary charge and a hung jury on the alternative charge still attracted the standard 20 per cent utilitarian discount, producing a reduction from a ten-year starting point to eight years.
  • Where an infant manslaughter offence is found to be spontaneous, that characteristic is relevant to objective gravity, but its presence alone does not substantially reduce the seriousness of the offence when no other mitigating factor on the objective side can be identified.
  • Comparable first-instance and Court of Criminal Appeal decisions in infant manslaughter cases provided a useful sentencing range (six to nine years total, non-parole periods of three to four and a half years), though Hidden AJ confirmed each case must be assessed on its own facts and the range does not set fixed parameters.
  • A finding of special circumstances permitted a longer balance of term than the statutory norm, reflecting the court's assessment that the offender had genuine rehabilitation prospects requiring structured post-release supervision.
  • Prior convictions for violence against the same victim (the offender's partner) were taken into account in assessing criminal history, even where those offences post-dated the manslaughter and had already been separately punished.
