Facts
- Three defendants attempted to rob a 60-year-old petrol station attendant with a heart condition.
- The defendants wore masks and one carried a replica firearm during the attempted robbery.
- No physical force or contact was made with the attendant.
- The attendant died of a heart attack soon after the incident.
- The defendants were convicted of manslaughter based on their actions and appealed the decision.
Issues
- Whether the defendants’ actions could lawfully be said to have caused the victim’s death for the purposes of manslaughter, given there was no physical contact.
- Whether the jury should have taken into account the victim’s heart condition, which was unknown to the defendants, in assessing criminal responsibility.
- Whether the objective foreseeability test applies to determine if the actions created a risk of physical harm sufficient for manslaughter liability.
Decision
- The Court of Appeal quashed the manslaughter convictions.
- The court held that to establish liability, it must be shown that a reasonable person would have foreseen a risk of physical harm from the defendants’ actions.
- The jury should not have considered the victim’s heart condition, as the defendants were unaware of it.
- The decision introduced the "reasonably foreseeable" test for causation, emphasizing that hidden weaknesses in the victim are irrelevant if not known to the defendant.
Legal Principles
- Liability for manslaughter by unlawful act depends on whether a reasonable person would recognize a risk of physical harm, not on the actual extent of force used.
- The objective test is applied, focusing on the viewpoint of a person of normal judgment rather than the unique vulnerabilities of the victim.
- Causation in manslaughter is satisfied if a direct link between the defendant's act and the death is established and the risk would have been apparent to a reasonable person.
- The case distinguishes itself from others, such as R v Watson, by clarifying that defendant’s knowledge of the victim's condition can be relevant, but only when that knowledge is present.
Conclusion
R v Dawson (1977) reaffirmed the use of the objective reasonable person test in unlawful act manslaughter, holding that liability arises only where physical harm as a result of the defendant’s actions would be foreseeable to an ordinary person, irrespective of the victim’s unknown frailty or the minimal force involved.
