REGINA v DUTHIE

[1999] NSWSC 1224

Homicide

Citation: REGINA v DUTHIE [1999] NSWSC 1224 (revised 26/06/2000)
Court: Supreme Court of New South Wales, Criminal Division
Date: 15 December 1999
Judge(s): Newman J


Background

The accused, a 35-year-old male prisoner on remand at Silverwater Metropolitan Remand Centre, was initially charged with the murder of his cellmate. The cellmate, an Aboriginal man on remand for a larceny matter, had been placed in the accused's cell on 21 February 1998 after prison authorities identified him as emotionally disturbed. The two men knew each other from a prior period of incarceration and were regarded as friends.

Both men had recently been using drugs and were administered Valium upon admission. The accused claimed they entered into a suicide pact, that the killing was carried out at the deceased's request, and that he understood his actions to constitute euthanasia. The accused strangled the deceased with a shoelace at approximately 8 pm, and did not raise the alarm until after 11 pm, stating he did not wish to assist authorities.

The Crown accepted a plea of guilty to manslaughter in full satisfaction of the murder indictment, on the basis that the accused's criminal responsibility was diminished at the time by an abnormality of mind.


  • Whether the Crown's acceptance of a manslaughter plea, on the basis of diminished responsibility due to abnormality of mind, was appropriate in the circumstances
  • What sentence was appropriate for the manslaughter, having regard to both the objective gravity of the offence and the accused's subjective circumstances
  • Whether special circumstances existed justifying a departure from the standard ratio between minimum and additional terms

Decision

Newman J accepted that the Crown was right to accept the manslaughter plea. The court found that the killing was not motivated by anger or malice, but by a misguided belief that the accused was performing an act of euthanasia, in circumstances where both men were drug-affected and had agreed to die together. The court noted that euthanasia is not a defence to unlawful homicide in New South Wales.

The court found that the accused had an underlying mental condition, separate from drug intoxication, which diminished his moral culpability. A psychiatrist's report confirmed an abnormality of mind. The accused also had a difficult personal history, including childhood trauma and long-term substance dependence, which the court took into account as mitigating factors going to subjective circumstances.

On the question of deterrence, the court found that general deterrence carries little weight where the offender suffers from a mental abnormality. The accused's guilty plea, entered at the first appropriate opportunity, was treated as evidence of remorse and contrition, as well as acknowledged on the pragmatic ground of saving court time and expense.

The court determined that although a custodial sentence was clearly required given that a human life had been deliberately taken, the case did not warrant a sentence at the upper end of the manslaughter range. A head sentence of eight years penal servitude was imposed, with special circumstances found to justify a longer-than-standard additional term relative to the minimum term.


Orders Made

  • Head sentence of eight years penal servitude
  • Minimum term of five years, reduced by time already served (15 months and 25 days), resulting in an effective minimum term of three years, eight months and five days commencing 15 December 1999 and expiring 19 August 2003
  • Additional term of three years commencing 20 August 2003 and expiring 19 August 2006
  • Eligible for release on parole on 19 August 2003

Key Takeaways

  • The Supreme Court confirmed that euthanasia does not constitute a defence to unlawful homicide in New South Wales, regardless of the accused's sincere belief that the killing was a compassionate act.
  • A finding of diminished responsibility due to abnormality of mind does not preclude a custodial sentence for manslaughter; it affects the weight given to general deterrence and the assessment of moral culpability rather than removing the need for imprisonment.
  • Where an offender's mental condition means they cannot be regarded as a typical offender, general deterrence is given reduced weight in sentencing, consistent with R v Scognamiglio (1991) 56 A Crim R 81.
  • A guilty plea entered at the first appropriate opportunity warrants a discount on sentence both as a reflection of remorse and on the pragmatic ground of conserving court resources, following R v Bennetts (unreported, Court of Criminal Appeal, 17 June 1993).
  • Manslaughter is described in the authorities as a "protean crime" covering a wide range of conduct; the sentence must nonetheless reflect the gravity of a deliberate taking of human life, even where objective culpability falls well short of the most serious cases.
