Citation: R v Dunn [2000] NSWCCA 377
Court: New South Wales Court of Criminal Appeal
Date: 30 August 2000
Judge(s): Studdert J, Dowd J, Bell J


Background

The applicant, a 48-year-old marine and mechanical engineer with no prior criminal history, was convicted after a jury trial of malicious wounding with intent to cause grievous bodily harm under s 33 of the Crimes Act 1900 (NSW). The conviction arose from an incident on 16 April 1998 in Dorrigo, where he fired six bullets from a .38 Smith and Wesson revolver at his neighbour, who had been in a relationship with the applicant's wife and whom the applicant mistakenly believed had sexually interfered with his daughter.

The applicant had planned the attack with some deliberateness: he used a motel under a false name the night before, fitted his vehicle with false registration plates, wore a disguise, and waited for hours for the victim outside a hotel. All six shots struck the victim in the lower half of his body. By good fortune, no major blood vessels or bones were hit.

The sentencing judge, Ireland J, imposed a minimum term of five years and six months penal servitude and an additional term of three years and six months. The applicant sought leave to appeal on the ground that the sentence was excessive, raising issues of self-defence, mental disorder, and the sentencing court's treatment of his psychological conditions.


  • Whether the sentencing judge erred in finding that neither limb of self-defence was available on the facts.
  • Whether the sentencing judge adequately applied the principles from R v Engert when assessing the significance of the applicant's mental disorders (longstanding depression and obsessive compulsive personality disorder) on sentence, including the extent to which general deterrence should have been discounted.
  • Whether the total sentence of nine years was excessive having regard to the applicant's good character, psychological conditions, and organic brain syndrome.

Decision

The Court of Criminal Appeal granted leave to appeal but dismissed the appeal, finding no error in the sentence imposed by Ireland J.

On the self-defence ground, the Court found Ireland J was entitled to reject both limbs of the defence. Notably, counsel who appeared for the applicant at sentencing had conceded before Ireland J that nothing excused the applicant attending Dorrigo armed and shooting the victim.

On mental disorder, the Court applied the principles from R v Engert and found that the conditions the applicant suffered did not rise to the level of psychosis or a distortion of mental processes sufficient to require a meaningful discount for general deterrence. The applicant retained full awareness of his actions and choice over his conduct. His mistaken beliefs, while contributed to by his psychological condition as the Crown conceded at trial, did not deprive him of the capacity to know what he was doing.

The Court accepted that the applicant's good character, psychological state, and organic brain syndrome were genuine mitigating factors. However, it held that these were appropriately offset by the objective seriousness of the offence, which sat at the very top of the sentencing range. Statistical data from the Judicial Commission showed that 22 per cent of offenders in comparable cases received a total sentence greater than that imposed on the applicant, confirming the sentence was within range.


Orders Made

  • Leave to appeal granted.
  • Appeal dismissed.

Key Takeaways

  • The Court of Criminal Appeal confirmed that mental disorders such as depression and obsessive compulsive personality disorder do not automatically require a significant discount for general deterrence at sentencing, particularly where the offender retained awareness and choice at the time of the offence.
  • Under the Engert principles, the extent to which mental disorder affects the sentencing calculus depends on whether it caused psychosis or distorted the offender's mental processes, not merely whether it contributed to mistaken beliefs.
  • Where an offence sits at the very top of the objective seriousness range, personal mitigating factors including good character and psychological conditions may be appropriately offset rather than treated as grounds for a reduced sentence.
  • In dismissing the appeal, the Court affirmed the sentencing judge's approach of weighing all relevant factors holistically under s 5(2) of the Sentencing Act 1989 (NSW).
  • Statistical data from the Judicial Commission formed part of the Court's analysis in confirming the sentence was within an appropriate range for the offence.
