Citation: Regina v A S Moffatt [No 1] [1999] NSWSC 168
Court: Supreme Court of New South Wales, Criminal Division
Date: 8 March 1999
Judge(s): Kirby J
Background
The accused stood trial before Kirby J sitting alone on a charge of murder. The deceased, a 43-year-old man, died following an incident involving the accused. The accused had made admissions, both to neighbours and to police in a recorded interview (an ERISP tape), describing striking the deceased on the chest with the flat of a claw hammer and then strangling him.
The deceased had significant pre-existing health conditions: severe coronary arteriosclerosis with 75% stenosis of the left anterior descending coronary artery, a condition capable of causing a spontaneous and fatal heart attack. At the time of death, the deceased also had a blood alcohol level of 0.48 g/100 ml, a level at which acute ethanol intoxication could itself be fatal.
The Crown case was still not formally closed at the time of this ruling, because the admissibility of the ERISP interview had been stood over for later determination. Kirby J nonetheless addressed the application for a verdict by direction on the assumption that the interview formed part of the Crown case.
Legal Issues
- Whether, at the close of the Crown case, there was sufficient evidence of causation capable of satisfying a jury beyond reasonable doubt that the accused's actions caused the death of the deceased.
- Specifically, whether the Crown had adduced evidence capable of excluding two alternative causes of death: a spontaneous heart attack arising from the deceased's arteriosclerosis, and death from acute ethanol intoxication.
Decision
Kirby J dismissed the application for a verdict by direction on the murder count. In accordance with the established approach, his Honour assessed whether the Crown case, taken at its highest, disclosed evidence capable of satisfying a jury beyond reasonable doubt on the issue of causation. The question of causation is to be resolved by the application of common sense, not philosophical or scientific analysis, and the relevant test is whether the accused's actions were a substantial or significant, or the operating, cause of death.
The forensic pathologist, Dr Christopher Lawrence, attributed death to the combined effects of compression of the neck, blunt force chest injury, and acute ethanol intoxication. He also identified arteriosclerotic cardiovascular disease as a significant contributing condition. While he acknowledged his post-mortem findings were consistent with a spontaneous heart attack as one possible cause, his evidence read as a whole, and particularly his re-examination, provided material capable of supporting a finding that the accused's conduct was the substantial, significant, or operating cause of death.
Kirby J accepted that the accused's admissions in the ERISP interview, describing multiple blows to the chest and prolonged manual strangulation, provided a factual foundation for that conclusion. On the basis of the pathologist's evidence and the accused's admissions taken together, there was sufficient evidence capable of satisfying a jury that the Crown had excluded causes of death unrelated to the accused's conduct.
The application was dismissed, though Kirby J noted it could be renewed once the admissibility of the ERISP interview had been finally determined.
Orders Made
- The application for a verdict by direction on the murder count was dismissed.
Key Takeaways
- Causation in a criminal trial is assessed by applying common sense to the facts, not by resolving philosophical or scientific uncertainty about the precise mechanism of death.
- Where a deceased has pre-existing conditions capable of causing independent fatal events, a Crown case on causation is not necessarily defeated: it is sufficient that evidence is capable of satisfying a jury that the accused's conduct was the substantial, significant, or operating cause of death, following Royall v R.
- A direction for acquittal is inappropriate where, reading the medical evidence as a whole, a jury could find the Crown had excluded causes of death unrelated to the accused's actions, even if alternative causes were theoretically consistent with the post-mortem findings.
- In dismissing the application, Kirby J preserved the accused's ability to renew the challenge after the admissibility question concerning the ERISP interview was resolved, reflecting the procedurally conditional posture of the ruling.
- Admissions in a police interview, assessed alongside expert forensic evidence, can together constitute sufficient material for a causation finding at the directed verdict stage.
