Intentionally causing serious injury is a serious criminal offence under section 16 of the Crimes Act 1958 (Vic). It reflects the law's grave view of conduct that is deliberately aimed at causing severe physical or mental harm to another person. A conviction carries a maximum penalty of 20 years imprisonment.

Intentionally causing serious injury is a strictly indictable offence heard in the County Court of Victoria, following committal proceedings in the Magistrates’ Court. At Angus Cameron and Partners, we have represented countless clients charged with serious assault offences across all Victorian courts.

If you or someone you know has been charged with intentionally causing serious injury, it is essential to obtain experienced legal advice immediately. The elements of the offence are specific, and there may be important defences available depending on the circumstances.

Elements

The prosecution must prove two elements beyond reasonable doubt:

  • you caused serious injury to another person; and
  • you intended to cause serious injury to that person.

Serious injury

A "serious injury" is defined in the Crimes Act 1958 (Vic) as an injury that endangers life or is substantial and long-term. It includes serious disfigurement and impairment of a bodily function. Whether an injury meets this threshold is a question for the jury, based on the medical and other evidence.

Intention

This is typically the central issue in these proceedings. The prosecution must prove that you specifically intended to cause serious injury — that is, that causing serious injury was your purpose, or that you knew it would result from your conduct as a matter of substantial certainty.

It is not sufficient that you intended to cause some injury, or that you acted recklessly. If intention cannot be proved, a charge of recklessly causing serious injury under section 17 of the Crimes Act 1958 (Vic) may arise instead.

Aggravated offence: Circumstances of gross violence

Where the offending involves “circumstances of gross violence”, a separate and more serious charge arises under section 15A of the Crimes Act 1958 (Vic). The maximum penalty remains 20 years imprisonment, but a mandatory minimum non-parole period of 4 years applies. If the victim is an on-duty emergency worker, custodial officer, or youth justice custodial worker, the mandatory minimum non-parole period increases to 5 years. A court cannot impose a lesser non-parole period unless it finds a special reason exists.

“Circumstances of gross violence” exist where any of the following applies:

  • the offender planned in advance to engage in conduct that they intended, were reckless as to, or where a reasonable person would have foreseen would likely cause serious injury;
  • the offender participated in a joint criminal enterprise with two or more other people to cause the serious injury;
  • the offender planned in advance to have an offensive weapon, firearm, or imitation firearm and used it to cause the serious injury;
  • the offender continued to cause injury after the victim was incapacitated; or
  • the offender caused the serious injury while the victim was already incapacitated.

The gross violence offences are indictable only and cannot be heard in the Magistrates’ Court. If you are facing a charge under section 15A, it is critical to obtain specialist legal advice without delay.

Defences

Being charged with this offence does not mean you will be convicted. There are several defences that may be available depending on the circumstances of your case.

Self-defence

If you genuinely believed your actions were necessary to defend yourself or another person, and your response was reasonable in the circumstances as you understood them, self-defence may be available. A successful self-defence argument results in an acquittal.

Lack of intention

If the prosecution cannot establish that you intended to cause serious injury — for example, where your conduct was reckless rather than deliberate, or where the injury was accidental — the specific intent required for this charge will not be made out.

Mental impairment

If you were suffering from a mental impairment at the time of the alleged offence that affected your understanding of what you were doing or that it was wrong, a defence of mental impairment may be available.

Intoxication

In rare circumstances, evidence of intoxication may be relevant to whether you were capable of forming the necessary intention to cause serious injury. This is a complex area of law and requires careful consideration with an experienced lawyer.

Insufficient or improperly obtained evidence

The prosecution must prove each element beyond reasonable doubt. If the evidence is weak, unreliable, or was obtained unlawfully, there may be strong grounds to contest the charge.

FAQs

What is the difference between intentionally and recklessly causing serious injury?

The difference lies in the mental element. Intentionally causing serious injury requires that causing serious injury was your purpose. Recklessly causing serious injury requires only that you were aware that serious injury was a probable consequence of your conduct. Both are serious charges, but intentional conduct attracts the higher maximum penalty of 20 years.

What counts as a "serious injury"?

A serious injury is one that endangers life, is substantial and long-term, involves serious disfigurement, or results in significant impairment of a bodily function. Whether an injury meets this threshold is ultimately a question for the jury.

What if the injury occurred during a fight that both parties agreed to?

Consent is generally not a defence to intentionally causing serious injury. The law does not permit a person to consent to the infliction of serious injury upon themselves for no good reason. This is a complex area and requires legal advice specific to your circumstances.

Do I need a lawyer if I am charged with intentionally causing serious injury?

Absolutely. This is a serious charge carrying a maximum of 20 years imprisonment. The legal and factual issues involved are complex, and an experienced criminal lawyer is essential to ensure every available defence is properly considered and your rights are protected.

Is intentionally causing serious injury an indictable offence in Victoria?

Yes. It is a strictly indictable offence heard in the County Court of Victoria following committal proceedings in the Magistrates’ Court.

What is the average sentence for intentionally causing serious injury in Victoria?

Sentences vary depending on the severity of the injury, the circumstances of the offending, and the offender’s personal background. Courts consider all relevant circumstances. We can provide a realistic assessment of likely outcomes once we have reviewed the full facts of your matter.
