Your primary defence in any legal proceeding is knowledge. That is why it is necessary to know and study the legal implications and seek expert legal representation when it comes to serious, severe cases like involuntary manslaughter.
In Australia, the crime of manslaughter is treated as a homicide offence; however, unlike murder, as defined under law, there is no requirement to intend either death or grievous bodily harm but only where a person’s death is caused by a person’s individual’s negligent or unlawful conduct.
We at Daniel Wakim Law Firm feel that your concerns about such matters are our priority. Having a knowledgeable involuntary manslaughter lawyer on your side could mean life-altering results for you or a loved one facing such charges. Read on and get educated on what manslaughter is, and how you can fight it.
What is Involuntary Manslaughter?
Involuntary manslaughter has been seen as an unintended killing up to now, particularly in specific situations or at particular times when one is absolved of the responsibility for the death of another, especially when the incident was caused by provocation or was a compulsory self-defence.
Legally, there are two primary categories of manslaughter :
- Manslaughter by Gross Negligence
- Manslaughter by an Unlawful and Dangerous Act
Each has its legal thresholds and requirements that prosecutors must prove beyond a reasonable doubt.
Involuntary Manslaughter by Gross Negligence
A charge of manslaughter by gross negligence arises when an individual owes a duty of care to another but fails to act in a manner that a reasonable person would, resulting in death. This applies in situations such as medical negligence, workplace incidents, or cases where someone is in a position of responsibility (e.g., a caregiver or property owner) but fails to take reasonable precautions.
Elements of Gross Negligence Manslaughter
For the prosecution to establish manslaughter by gross negligence, they must prove the following:
- The accused owed a duty of care to the victim.
- The accused breached that duty through an act or omission.
- The breach directly caused the victim’s death.
- The negligence was so severe and reckless that it should be punished as a criminal act.
This type of involuntary manslaughter requires proof that the accused’s conduct was far below what any reasonable person would consider acceptable, and that it created a significant risk of death or serious injury.
Examples of Gross Negligence Manslaughter
- A doctor failing to provide urgent medical treatment that any competent professional would have given.
- An employer ignoring serious workplace safety hazards, leading to a fatal accident.
- A caregiver neglecting a vulnerable person in a way that results in their death.
Involuntary Manslaughter by an Unlawful and Dangerous Act
Involuntary manslaughter refers to every death caused by a person engaged in an unlawful activity not necessarily aimed at causing death or injury to the person killed; on the other hand, in gross negligence manslaughter, there is an original act, the need for which had the existence of a duty of care towards the victim.
Key Elements of Unlawful and Dangerous Act Manslaughter
To convict someone of manslaughter by an unlawful and dangerous act, the prosecution must prove:
- The accused deliberately committed an unlawful act.
- The act was inherently dangerous, meaning a reasonable person would recognise it as carrying a risk of serious injury.
- The act caused the victim’s death.
Examples of Unlawful and Dangerous Act Manslaughter
- Throwing a punch during an argument that results in the victim falling and hitting their head fatally.
- Engaging in reckless driving that causes a crash leading to someone’s death.
- Setting off fireworks in an unsafe manner, causing a fatal fire.
Unlike gross negligence manslaughter, this category does not require intent to harm; it only requires the act to be unlawful and dangerous.
Defences to Involuntary Manslaughter Charges
Facing involuntary manslaughter charges does not mean an automatic conviction. There are several legal defences that an experienced defence lawyer can argue to challenge the prosecution’s case.
1. Lack of Causation
A central element of manslaughter is that the accused’s actions must have directly led to the victim’s death. Suppose an intervening factor caused the fatal outcome, such as pre-existing medical conditions or another party’s actions. In that case, the defence may argue that the accused’s actions were not the cause of death.
2. The Act Was Not Dangerous
For unlawful and dangerous act manslaughter, the defence may argue that the act was not dangerous under reasonable standards. If the act is not expected to result in serious harm, it may not meet the legal definition required for a conviction.
3. Self-Defence
If the accused’s actions responded to a threat of harm, they may argue self-defence. However, this must be proportionate to the threat faced.
4. Lack of Negligence
For gross negligence manslaughter, the defence can argue that the accused’s actions did not fall grossly below the expected standard of care. If negligence is minimal or within reasonable professional judgment, a conviction may not stand.
5. Duress or Necessity
Suppose the accused was forced into committing the act due to threats of violence (duress) or had to act in an emergency to prevent more significant harm (necessity). In that case, these can be raised as legal defences.
Penalties for Involuntary Manslaughter in Australia
The penalties for involuntary manslaughter in Australia are severe, with a maximum sentence of 25 years imprisonment. However, the actual penalty depends on various factors, including:
- The level of negligence or recklessness involved.
- Whether there were aggravating factors (e.g., repeated warnings ignored).
- The accused’s prior criminal history and character.
- Whether the accused showed remorse and cooperated with authorities.
A skilled involuntary manslaughter lawyer can advocate for a more lenient sentence, mainly if mitigating factors exist.
