In any case involving a death caused by another, investigators must first assess whether the circumstances meet the legal threshold for murder or for manslaughter. The distinction between murder and manslaughter is not merely technical. It determines how a case is prosecuted and ultimately, the sentence that might be imposed on a finding of guilt.
What is the difference between murder and manslaughter?
Both offences involve the unlawful killing of another person, but what separates them is the mental state of the accused at the time of the act.
Murder requires proof that the accused:
- Intended to kill the victim, or
- Intended to cause grievous bodily harm, or
- Acted with reckless indifference to human life
Manslaughter, by contrast, includes:
- Voluntary – when a person kills another intentionally, but there was provocation, or an abnormality in the mind. Excessive self-defence can also be voluntary manslaughter.
- Involuntary by unlawful and dangerous act – where a person causes the death of another person by an act that is both unlawful and dangerous
- Involuntary by criminal negligence – where a person causes death with a very high degree of negligence.
How do prosecutors decide which charge to proceed with?
Prosecutors must assess whether the evidence is capable of proving the mental element of murder beyond reasonable doubt. If it is not, a charge of manslaughter may be more appropriate. You can read more about how NSW courts approach murder and manslaughter charges.
In practice, prosecutors consider many factors when deciding what charge to lay, including:
- The words or conduct of the accused — statements made before, during, or after the act can indicate intent
- The nature of the act — the type of weapon used, the number of strikes, or the manner of the attack may speak to what the accused intended
- The relationship between the parties — prior threats, history of violence, or a motive can be relevant to proving intent
- Expert evidence — forensic, medical, and psychiatric evidence may all be relied upon.
The charge may also change over the course of proceedings. A person may also be charged and face trial for murder but be found guilty of manslaughter.
What are the penalties?
The difference in penalties is substantial and reflects the difference in moral culpability between the two offences.
- Murder carries a maximum penalty of life imprisonment, with a standard non-parole period of 20 years
- Manslaughter carries a maximum penalty of 25 years imprisonment, with no standard non-parole period
For many serious offences in NSW, including murder, the law imposes standard non-parole periods. These are guideposts that indicate the appropriate non-parole period for an offence in the middle of the range of objective seriousness. A court may move above or below that guidepost depending on the circumstances, but it must provide reasons for doing so.
Can a murder charge be reduced to manslaughter?
A murder charge can be reduced to manslaughter. Partial defences to murder reduce the criminal culpability of the accused person, and if made out, a jury would be directed to return a verdict of guilty to manslaughter. Under NSW law, partial defences include:
- Extreme provocation — where the conduct of the deceased amounted to a serious indictable offence and caused the accused to lose self-control, and the ordinary person would also lose control in the same circumstances
- Substantial impairment by mental health impairment or cognitive impairment — where the accused’s capacity to understand or control their conduct was substantially impaired at the time of the act.
