Homicide
CRIMINAL LAW SENTENCE MURDER KILLING OF NEWBORN BABY BY HIS FATHER GRAVITY OF OFFENCE FINDING OF SPECIAL CIRCUMSTANCES

Citation: R v AS (Sentence) [2023] NSWSC 1575
Court: Supreme Court of New South Wales
Date: 13 December 2023
Judge(s): Wilson J

Background

The offender, an Afghan-born man who had settled in Australia, was convicted by jury of the murder of his infant son, Baby A, following a trial in August and September 2023. Baby A was born in April 2020 and was fatally injured on 27 June 2020, when he was nine weeks old. He died one month later, on 20 July 2020.

The fatal injury occurred while the mother had briefly left the family home, a window of approximately 15 to 20 minutes. The offender shook the baby so vigorously that catastrophic rotational force was applied to the infant's head, causing severe brain injuries from which Baby A could not recover. The mother had previously warned the offender about the dangers of shaking a baby. Consistent with the jury's verdict of murder, the court found the offender had been recklessly indifferent to his son's life.

The offender made immediate admissions to neighbours and repeated them in the presence of police at Auburn Hospital. Despite those admissions, he maintained a contested trial and did not express genuine remorse for his conduct.

  • What sentence was appropriate for the murder of a child under 18, where the standard non-parole period (SNPP) is 25 years?
  • What weight should be given to the offender's diagnosed post-traumatic stress disorder (PTSD) in assessing moral culpability?
  • Whether special circumstances existed under s 44(2) of the Crimes (Sentencing Procedure) Act 1999 (NSW) to justify a non-parole period shorter than the statutory default ratio.
  • What role should general deterrence, specific deterrence, and rehabilitation play in the sentence?
  • How should the absence of remorse and the offender's former good character be weighed?

Decision

Wilson J found that the murder of a helpless infant by his father was an offence of the gravest kind. Parents carry an overriding obligation to protect their children, and a father who instead fatally injures his baby commits a profound breach of that duty. Despite the SNPP of 25 years serving as a legislative guidepost for such offences, the court assessed the appropriate sentence by reference to all circumstances, including factors that reduced the offender's moral culpability.

The offender's PTSD, which arose from serious traumatic experiences he had suffered before and during his journey to Australia, was found to have diminished his moral culpability to a meaningful degree. While the diagnosis did not excuse his conduct, it provided a medical basis for understanding why his capacity to cope with the demands of caring for a young baby may have been impaired. The court accepted this as a genuine mitigating factor.

The absence of remorse was treated as a neutral rather than an aggravating matter; it did not increase the sentence, but it also contributed nothing in mitigation. The offender's former good character, strong work ethic, and reasonably positive rehabilitation prospects weighed in his favour. Specific deterrence and community protection were assessed as minor considerations given the circumstances, but general deterrence was identified as a significant sentencing purpose, reflecting the courts' role in protecting children from violence by those closest to them.

Special circumstances were found to exist, justifying a non-parole period proportionally shorter than the standard ratio. The longer parole period was directed at supporting the offender's rehabilitation, which the court considered to be a genuine prospect over the longer term.

Orders Made

  • The offender was sentenced to 18 years' imprisonment, commencing 20 August 2020 and expiring 19 August 2038.
  • A non-parole period of 12 years and 6 months was fixed, expiring 19 February 2033.

Key Takeaways

  • A PTSD diagnosis can reduce an offender's moral culpability for murder and justify a sentence below the applicable SNPP, provided the condition is causally connected to circumstances relevant to the offending.
  • Where an offender's former good character and rehabilitation prospects are genuinely positive, those factors can support both a degree of leniency and a finding that specific deterrence carries reduced weight.
  • Special circumstances under s 44(2) of the Crimes (Sentencing Procedure) Act 1999 (NSW) were established here, producing a non-parole period proportionally shorter than the statutory default, with the extended parole period directed to rehabilitation.
  • Lack of remorse following a contested trial does not automatically become an aggravating feature; the Supreme Court treated it as neutral in the overall sentencing calculus.
  • General deterrence carries particular weight in cases involving violence against young children, with the court emphasising that all members of the community, including the courts themselves, bear a responsibility to protect babies and children from harm.
