Brief rundown of the difference between murder & manslaughter in Australia.
Australia Criminal Law

In Australia, as in many other countries, there is a difference between murder and manslaughter. The difference is mainly in the intent and degree of culpability attached to the act that results in the death of another person. Here's a brief rundown of the difference between murder and manslaughter in Australia:

Murder is the more serious charge and involves the intentional killing of another person with malice aforethought. Malice aforethought means intention to cause death or grievous bodily harm. It also means acting with reckless indifference to human life.

The key element in murder is intent. If the prosecution can prove beyond a reasonable doubt that the accused had the intention to cause death or serious harm, they can be convicted of murder.

Manslaughter is the lesser charge and typically involves the unlawful killing of another person without malice aforethought. There are two main types: voluntary or involuntary manslaughter (see here).

1. Voluntary Manslaughter

  • This occurs when a person intentionally kills another person but can claim mitigating circumstances that reduce their level of culpability.
  • For example, if a person kills someone in the heat of the moment due to sudden provocation. Or under extreme emotional distress. This may be classified as voluntary manslaughter instead of murder.

2. Involuntary Manslaughter:

  • Involuntary manslaughter means a person unintentionally kills another person but does so through their negligence or reckless behaviour.
  • This could include cases where a person acts without due care or caution and a fatal accident occurs.

Each state and territory in Australia has its own legislation and laws. So there may be some slight variations in the definitions and classifications of murder and manslaughter. Furthermore, the penalties for these crimes can vary depending on the circumstances and the jurisdiction of the commission of the crime.

Australian Legislation Difference Between Murder and Manslaughter

Now let's break down the difference between murder and manslaughter. Below is a comparison of the elements in each crime.

Murder

  1. Intent: Murder involves the intentional killing of another person. The accused must have had the intention to cause death or grievous bodily harm to the victim or acted with reckless indifference to human life.
  2. Malice aforethought: There must be malice aforethought, which means intention to cause death or serious harm. This includes situations where the accused planned or premeditated the killing.
  3. Causation: The prosecution must show that the accused person's actions were the cause of the victim's death.
  4. Mental state: The accused must have the necessary mental state for murder, which includes intention or reckless indifference.

Manslaughter:

  1. No intent: Manslaughter occurs when a person unlawfully kills another person without malice aforethought. Unlike murder, there is no specific intent to cause death or grievous bodily harm.
  2. Voluntary manslaughter: This type of manslaughter applies when the accused caused the death of another person in response to sudden provocation or under circumstances that caused them to lose control. The provocation must be of such a nature that a reasonable person might have been similarly provoked.
  3. Involuntary manslaughter: Involuntary manslaughter generally means unintentional killings that result from negligence or reckless behaviour. This can include situations where the accused failed to exercise reasonable care or engaged in dangerous conduct that led to the death.

As mentioned above, the definitions and legal elements of murder and manslaughter can vary between Australian states and territories. Each jurisdiction has its own legislation, case law, and specific legal tests for these offences.

In New South Wales, Section 18 of the Crimes Act 1900 defines murder and manslaughter. According to this section, any form of unlawful killing that does not meet the criteria for murder is classified as manslaughter and can be punished by law.

In Victoria, the common law deals with offences of murder and manslaughter, while the Crimes Act 1958 deals with other forms of homicide.

In Queensland, Section 302 of the Criminal Code 1899 defines the offence of murder. If a person unlawfully causes death under circumstances that do not meet the criteria for murder, they can be charged with manslaughter under Section 303.

It is best to refer to the relevant criminal legislation and legal resources specific to the jurisdiction in question for more information.

Murder vs Manslaughter: Sentencing in NSW

The maximum sentence for murder is life imprisonment or a life sentence, while under Section 24 of the Crimes Act 1900 (NSW), manslaughter has a maximum penalty of 25 years.

In New South Wales, there is no minimum sentence for murder, but the non-parole period is typically 20 years. New South Wales also recognises the partial defence of provocation where extreme provocation can lead to a charge of manslaughter instead of murder.

In such cases, if a person has committed murder under extreme provocation, they may be convicted of manslaughter instead.

New 2024 Law on Manslaughter: Industrial Manslaughter Act 2004

The NSW Parliament has just passed a new law in relation to manslaughter. The Work Health and Safety Amendment (Industrial Manslaughter) Act 2004 creates the offence of industrial manslaughter. This law has heavy penalties, as it can fine a body corporate up to AUD 20,000,000 and 25 years imprisonment for an individual.

The punishable act under this new law is the act of engaging in grossly negligent conduct that breaches work health and safety duties that they owe to an employee or individual and causes the death of such individual or employee. Persons conducting a business or undertaking (PCBUs) and its officers are the persons who can be charged with this offence.

In summary, the law on industrial manslaughter:

  • Makes causing a workplace death through gross negligence an offence;
  • Holds businesses and individuals accountable for workplace deaths;
  • Increases penalties for serious workplace health and safety breaches.

There is no malice afterthought in these cases, unlike in the crime of murder, where there is intentional killing of an individual.
