R v McCann

[2012] NSWSC 1462

Homicide
CRIMINAL LAW SENTENCING MANSLAUGHTER EXCESSIVE SELF DEFENCE

Citation: R v McCann [2012] NSWSC 1462
Court: Supreme Court of New South Wales
Date: 29 November 2012
Judge: Barr AJ

Background

The offender, a 67-year-old man, was the owner-occupier of a house in Springwood where he took in lodgers. The deceased was one such lodger who had returned to the property after a period working interstate. The offender resented the deceased's continued presence and had sought police assistance to have him removed. The deceased was briefly arrested and then released, and he returned to the property that same night.

In the early hours of the morning, the two men encountered each other at the rear of the house. A physical confrontation followed, during which the offender strangled the deceased with a nylon cord. The offender immediately told another lodger what had occurred and handed himself over to police when they arrived.

A jury found the offender guilty of manslaughter on the basis of excessive self-defence. The offender suffered from a significant psychiatric condition that caused him to experience fear in circumstances where a person without that illness would not, and to misinterpret the intentions of others. He had harboured exaggerated fears about the deceased, partly based on distorted accounts of the deceased's past.

  • What sentence was appropriate for a manslaughter conviction arising from excessive self-defence?
  • What weight should be given to the offender's serious mental illness in assessing moral culpability?
  • How should the offender's age, health, and the conditions of custody bear on the structure of the sentence, particularly the ratio of non-parole period to total term?
  • To what extent did prospects of rehabilitation and risk of re-offending affect the sentencing exercise?

Decision

Barr AJ found that the offender's psychiatric condition was central to the offending. The illness caused him to misread the deceased's intentions and to experience fear disproportionate to any actual threat. This reduced his moral culpability, though it did not eliminate it. The court accepted that the offender had suffered injuries consistent with being struck by the deceased before the fatal act.

The court weighed the objective seriousness of the offence, which involved the deliberate application of a ligature to a man's neck, against the subjective circumstances, including the offender's age, lengthy psychiatric history, and the reduced culpability flowing from his mental illness. Specific deterrence was assessed as being of limited relevance given the offender's condition, but general deterrence remained relevant.

Rehabilitation was considered uncertain. The court could not conclude the offender would not re-offend, given ongoing uncertainties about his treatment and the fact that he had not fully come to terms with what he had done. The court noted that the offender would require supervision and medication for the remainder of his life, a matter that extended parole could not meaningfully address.

Because of the offender's age and the difficult custodial conditions he would face in order to receive appropriate psychiatric treatment, the court applied a lower non-parole period relative to the overall sentence term. This reflected the principle that an offender who serves their sentence particularly hard may warrant an adjusted parole structure.

Orders Made

  • The offender was sentenced to imprisonment for manslaughter.
  • Non-parole period: 3 years and 6 months, commencing 13 March 2011 and expiring 12 September 2014.
  • Balance of term: 3 years and 6 months, expiring 12 March 2018.
  • First eligible date for release to parole: 12 September 2014.

Key Takeaways

  • A psychiatric condition that causes an offender to misperceive danger and misinterpret the intentions of others can significantly reduce moral culpability in a manslaughter by excessive self-defence, even where the fatal act was deliberate in its physical execution.
  • Where an elderly offender will face particularly harsh custodial conditions in order to receive necessary treatment, the sentencing court may adjust the ratio of non-parole period to head sentence accordingly.
  • Prospects of rehabilitation are assessed as uncertain where an offender has not accepted responsibility and requires indefinite medical management; in such circumstances, the court found that an extended parole period could not substitute for ongoing long-term supervision and treatment.
  • General deterrence remained a relevant sentencing consideration despite the offender's mental illness, though specific deterrence was reduced in weight.
  • Victim impact statements were received and acknowledged by the Supreme Court in this matter, but the court confirmed they could not be taken into account in fixing the actual sentence.

Legislation and Cases Referenced

The judgment does not specify particular legislation or cases cited. The offence of manslaughter by excessive self-defence arises under the general law of New South Wales as modified by the Crimes Act 1900 (NSW), which provides the framework for partial defences to murder. No cases were expressly cited in the portions of the judgment provided.
