Grievous Bodily Harm Charges in Queensland — What Section 320 Actually Requires

Grievous bodily harm — often referred to as GBH — is one of the most serious violence to the person in the Queensland Criminal Code, carrying a maximum penalty of 14 years’ imprisonment. Because there is no “element” of assault in the charge the victim cannot consent to the application of that level of force. So, if people voluntarily engage in a consensual fight and one does GBH to the other, consent to engage in the fight is irrelevant. Also, provocation by the injured party during the fight is irrelevant.

Despite how the term “grievous” is viewed generally in the community, what actually counts as “grievous” bodily harm is a specific legal threshold, not simply a description of a serious-looking injury. Whether that threshold is met is frequently the central, contested issue in these prosecutions.

This article sets out how GBH is defined under Queensland law, the key offences involving GBH, sentencing considerations, and why the medical and forensic evidence in these matters requires careful early scrutiny.

The Offence: Section 320 of the Criminal Code

Under section 320, a person who unlawfully does grievous bodily harm to another commits a crime, carrying a maximum penalty of 14 years’ imprisonment. There is no element of intention in GBH. To secure a conviction, the prosecution must prove beyond reasonable doubt that the accused does an injury meeting the legal definition of GBH, and that the act causing it was unlawful — that is, contrary to law and not excused. The test of whether an accused “does” GBH is objective, based on what the ordinary reasonable person thinks was likely to result and which did result from the accused’s act or omission.

What Counts as Grievous Bodily Harm

“Grievous bodily harm” is defined in section 1 of the Criminal Code Act 1899 (Qld). It means:

• the loss of a distinct part or an organ of the body; or
• serious disfigurement; or
• any bodily injury of such a nature that, if left untreated, would endanger or be likely to endanger life, or cause or be likely to cause permanent injury to health — whether or not treatment was actually available.

This is a broader test than many people expect. An injury does not need to cause permanent bodily injury to qualify as GBH — it is enough that the injury, if left untreated, would have been likely to endanger life or cause permanent injury. This means the availability and effectiveness of medical treatment received after the injury does not necessarily prevent a charge of GBH from being made out.

Related and More Serious Offences

Several related provisions carry higher maximum penalties where additional elements are proven:

• Section 317 — acts intended to cause grievous bodily harm or prevent apprehension, which carries a maximum penalty of life imprisonment where intent is established;
• Section 328A(4) — dangerous operation of a vehicle causing grievous bodily harm, which carries increased penalties, particularly where aggravating circumstances such as intoxication or excessive speed are involved.

Serious Violent Offence Declarations

GBH is a listed offence under Schedule 1 of the Penalties and Sentences Act 1992 (Qld). This means that where a court imposes a sentence of 10 years or more, an offender is automatically convicted of a serious violent offence, and a court retains discretion to make a serious violent offence declaration for lesser sentences in appropriate cases. A declaration significantly increases the proportion of the sentence that must be served in actual custody before parole eligibility arises, rather than the standard parole eligibility calculation.

Why the Medical Evidence Matters

Because the legal definition of GBH turns on the nature and potential consequences of an injury — not simply how serious it appears — medical and forensic evidence is often the most contested part of these cases. For example, whether a particular fracture such as fractures to the facial bones meets the legal threshold can depend on conflicting expert opinion about the risk the untreated injury posed, the mechanism of injury, and the treatment actually required.

Where expert medical evidence is contested, or where video or other evidence bears on how an injury occurred, early and careful forensic analysis can be critical — both to whether GBH is made out at all, or whether a lesser charge (such as unlawful wounding or assault) more accurately reflects the evidence.

Possible Defences or Excuses

Defences or excuses are highly fact-dependent and must be assessed by a solicitor against the specific evidence, but may include:

• Self-defence — that the accused acted to defend themselves or another person in circumstances recognised by the Criminal Code; If properly raised the prosecution must disprove self defence beyond reasonable doubt.
• Accident — that the injury was not intended or foreseen and would not reasonably have been foreseen; If properly raised the prosecution must disprove self defence beyond reasonable doubt.
• Unsoundness of mind — a complete defence under section 27 where, at the time of the act, the accused was deprived of capacity to understand what they were doing, to control their actions, or to know they ought not do the act. The defence must prove the unsoundness of mind on the balance of probability; and
• Mistake of Fact- under s 24 where the accused had an honest and reasonable but mistaken belief in a state of things that would make them not criminally responsible for the act or omission to any greater extent than if the real state of things had been such as the person believed to exist. If properly raised the prosecution must disprove mistake beyond reasonable doubt

 Why Early Legal Advice Matters

GBH charges carry severe maximum penalties and frequently turn on contested expert medical evidence. Early legal advice can affect:

• Whether you should participate in a record of interview;
• Whether the medical evidence supports the charge as laid, or a lesser alternative;
• Whether independent expert medical opinion should be obtained; and
• Sentencing submissions, including whether a serious violent offence declaration should be opposed.
