Facts
- Three men attempted to rob a petrol station while wearing masks; one carried a fake gun.
- The petrol station attendant, aged 60, triggered an alarm, prompting the men to flee.
- The defendants were unaware that the attendant had a heart condition.
- Shortly after the incident, the attendant died from a heart attack.
- The defendants were initially convicted of manslaughter.
Issues
- Whether liability for unlawful act manslaughter requires foreseeability of harm as assessed by an objective standard.
- Whether knowledge of the victim's hidden health issues should be considered in determining foreseeability.
- Whether the harm for unlawful act manslaughter must be physical or if emotional distress is sufficient.
Decision
- The Court of Appeal overturned the manslaughter convictions.
- The Court held that the test for foreseeability is what a reasonable person present at the scene would expect, excluding knowledge of hidden health conditions.
- It was determined that a reasonable person would not have foreseen the risk of a fatal heart attack in these circumstances.
- The Court clarified that only physical injury, not fear or shock alone, satisfies the harm requirement for unlawful act manslaughter.
Legal Principles
- Foreseeability for unlawful act manslaughter must be judged objectively by the standard of a reasonable person present at the scene.
- The defendant's personal characteristics or knowledge, and the victim's hidden vulnerabilities, are excluded from this assessment.
- Legal causation in manslaughter relies on whether the consequence—physical harm—was a reasonably foreseeable result of the unlawful act.
- Emotional harm without accompanying physical injury does not satisfy the requirement for manslaughter.
- The objective standard introduced in this case ensures consistent and fair application of the law.
Conclusion
R v Dawson (1985) 81 Cr App R 150 established that foreseeability in unlawful act manslaughter is determined by what a reasonable person would have foreseen, ignoring hidden vulnerabilities of the victim; this objective standard remains central to the law on manslaughter.
