Study Notes

  • Murder is the unlawful and intentional killing of a human being by a person who acted voluntarily and without lawful justification.
  • Murder falls under homicide, which involves the killing of another person without legal justification.
  • Examples of other types of homicide include manslaughter, infanticide, child homicide, culpable driving causing death, and homicide by firearm.
  • Murder is a category 1 offence, requiring imprisonment unless exceptional circumstances exist.
  • The maximum penalty for murder is life imprisonment.

Elements of Murder

For a guilty verdict, the prosecution must prove beyond reasonable doubt:

  • The killing was unlawful.
  • The accused’s acts were voluntary.
  • The accused’s acts caused the victim’s death.
  • The accused acted with intent to kill or cause serious harm.

The Killing Was Unlawful

  • The prosecution needs to prove the accused lacked legal justification for causing the death.
  • Legal justifications include a soldier killing an enemy in battle, police during duty, self-defence, or duress.

The Accused's Acts Were Voluntary

  • The prosecution is required to establish the accused was awake, aware, and in control of their actions.
  • The act must be deliberate, not due to sleepwalking, seizure, or unintentional accident.

The Accused Committed Acts That Caused Death

  • The prosecution must show the accused's acts significantly contributed to the victim's death.
  • Causation must be proven, with a direct link between the accused's actions and the victim's death.
  • If the death would not have occurred without the accused's actions, they likely caused it.
  • An intervening event that breaks the causal link may absolve the accused of guilt.
  • The victim has to be a living person who has been born.

The Accused Acted With Intent

  • The prosecution must prove the accused acted with a 'guilty mind' (mens rea).
  • It must be proven that the accused either intended to kill or cause serious injury, OR knew that death or serious injury was probable from their actions.

Defences to Murder

  • If the prosecution fails to prove each element beyond reasonable doubt, the accused is not guilty.
  • The accused may argue that intent was absent, causation was broken, or their actions were lawful.
  • If one element of murder is missing, the accused might be charged with an alternative offence like manslaughter.

General Defences to Murder

  • Self-defence: The accused believed their actions were necessary to prevent death or significant serious injury to themselves or another.
  • Mental impairment.
  • Duress: Threat must involve death or significant serious injury. Family violence evidence may support duress. Duress is invalid if the threat comes from someone with whom the accused voluntarily associated to commit violence.
  • Sudden or extraordinary emergency: Must involve risk of death or serious injury.
  • Automatism.
  • Intoxication.
  • Accident.
