REGINA v. TRAN

[2003] NSWSC 373

Homicide
CRIMINAL LAW MANSLAUGHTER SENTENCE LEVEL OF CULPABILITY OFFENDER AFFECTED BY SLEEP DISORDER LACKED SPECIFIC INTENT FOR MURDER

Citation: Regina v Tran [2003] NSWSC 373
Court: Supreme Court of New South Wales
Date: 2 May 2003
Judge(s): Greg James J

Background

The offender pleaded guilty to the manslaughter of his partner after the Crown accepted that plea in full discharge of a murder indictment. The killing occurred on the night of 6 December 2001, when the offender and the deceased had consumed a large quantity of alcohol together before falling asleep in a spare bedroom at a friend's house.

The offender's account, given to police after his arrest at Sydney International Airport in February 2002, described waking from what he believed was a nightmare to find the deceased had died. Two medical experts, Professor Grunstein and Associate Professor Wheatley, provided reports concluding that it was reasonably possible the offender killed the deceased without any specific intent to kill or cause serious harm, and that his mental state at the time may have bordered on that of an automaton.

After the death, the offender wrapped the body in plastic, enlisted a friend's assistance to dispose of it, and later disposed of the deceased's property. He initially gave police a false account before making admissions approximately six weeks later.

  • What was the appropriate head sentence for manslaughter, having regard to the offender's profoundly diminished mental state arising from a sleep disorder combined with intoxication?
  • Whether the prospect of deportation could be taken into account when fixing the non-parole period (raised in Crown submissions).
  • Whether special circumstances existed under the Crimes (Sentencing Procedure) Act 1999 to justify a non-parole period bearing less than the standard three-quarters proportion to the head sentence.

Decision

Greg James J found that the offender's objective culpability sat at the lower end of the range for manslaughter, even when the post-death conduct (concealment and disposal of the body, use of another person's assistance, and disposal of the deceased's property) was taken into account. The medical evidence supported the view that the offender's mental state verged on automatism, meaning he lacked specific intent and likely had no conscious awareness that his actions were endangering the deceased. The plea, however, acknowledged that he performed a deliberate act that was objectively dangerous and unlawful.

On the deportation question, the Crown properly conceded, in light of the High Court's decision in Shrestha (1991) 173 CLR 48, that the prospect of deportation could not properly be used to adjust the non-parole period. The court accepted that concession.

Greg James J found special circumstances justifying a non-parole period of less than three-quarters of the head sentence. The relevant factors included the near-automaton mental state at the time of the offence, the offender's lack of prior criminal record and prior good character, the limited extent to which his act was truly willed, his good prospects of rehabilitation, and his lack of awareness of the consequences flowing from his diminished state of consciousness. The court concluded that the non-parole period should particularly reflect the limited culpability of the offence.

Orders Made

  • Head sentence of five years imprisonment, commencing 19 February 2002.
  • Non-parole period of two years and three months, expiring 18 May 2004.
  • Earliest eligible release date: 18 May 2004.

Key Takeaways

  • Where uncontested medical evidence established that an offender's mental state at the time of a killing verged on automatism due to a sleep disorder and alcohol, the Supreme Court treated this as placing the offence at the lower end of manslaughter culpability.
  • A near-automaton mental state, combined with no prior criminal record, good prospects of rehabilitation, and limited volitional awareness, can collectively constitute special circumstances under the Crimes (Sentencing Procedure) Act 1999, justifying a non-parole period below the standard three-quarters proportion.
  • Following Shrestha (1991) 173 CLR 48, the prospect of deportation is not a legitimate factor in fixing a non-parole period, and the Crown's concession on that point was accepted without reservation.
  • Post-offence conduct such as concealing and disposing of a body and enlisting another person's assistance was considered as an aggravating feature, but did not displace the finding that overall culpability remained low.
  • Even at the lower end of manslaughter culpability, the sentencing court found that the gravity of the offence still warranted a custodial sentence.
