谋杀

Under Section 18 of the Crimes Act 1900 (NSW), murder is defined as the unlawful killing of another person with:

• Intent to kill
• Intent to inflict grievous bodily harm
• Reckless indifference to human life
• Causing death during the commission of a crime punishable by at least 25 years imprisonment (constructive murder)

In the Australian Capital Territory (ACT), the definition is similar, but the charge is governed by the Crimes Act 1900 (ACT). Although there are subtle differences in terminology, the essential elements of the offence remain consistent across jurisdictions:

• Intent to kill or cause grievous bodily harm
• Recklessness or indifference to human life

Each Australian jurisdiction has similar definitions, with minor variations in terminology and procedure.

To secure a murder conviction, the prosecution must prove beyond reasonable doubt:

• The victim has died
• The accused caused the death through an act or omission
• The act was done with:
  • Intent to kill; or
  • Intent to cause serious bodily harm; or
  • Reckless indifference to human life; or
  • While committing another serious offence (constructive murder)

The prosecution must also exclude any valid legal defence raised by the accused.

Several complete or partial legal defences may apply, depending on your circumstances:

• Self-defence: You acted to protect yourself or another from serious harm.
• Duress: You were coerced into committing the act due to a serious threat.
• Necessity: You acted to prevent a greater harm.
• Automatism (Unconscious or Involuntary Acts):
  • Your conduct was not voluntary (e.g. due to sleepwalking, seizures, or trauma-induced dissociation).
  • Must be caused by external factors and not a mental illness.
  • Requires medical evidence to support the claim.
• Mental Illness:
  • You were suffering from a psychological condition at the time that impaired your ability to understand the nature of your actions or that your actions were wrong.
  • May lead to a special verdict of not guilty by reason of mental illness and possible detainment in a mental health facility.
• Provocation (Partial Defence):
  • Can reduce a murder charge to manslaughter.
  • Must show the deceased’s conduct provoked an extreme emotional response.

Each case is different. Our experienced team at Brightstone Defence can assess the best defence strategy for your case.

Murder carries a maximum penalty of life imprisonment. Sentencing outcomes depend on the case's specific circumstances, including:

• The level of intent and planning
• The vulnerability of the victim, such as children or emergency workers
• Presence of aggravating or mitigating factors

In NSW, murder of public officials, including police officers, may carry a standard non-parole period of 25 years. Similar sentencing standards exist in the ACT and other states, although terminology and guidelines may vary.

Courts across Australia consider factors such as remorse, rehabilitation prospects, prior criminal history, and level of cooperation when imposing sentence.
