Grievous Bodily Harm is a Tier-1 violence offence under Section 297 of the Criminal Code. It is distinguished from “Bodily Harm” by the severity and permanence of the injury.
Defining “GBH” The Code defines GBH as any bodily injury that:
-
Endangers, or is likely to endanger, life; OR
-
Causes, or is likely to cause, permanent injury to health. Common examples include broken jaws requiring surgery, permanent scarring, or internal organ damage. The definition applies even if the victim makes a full recovery due to modern medical intervention.
Maximum Penalties
-
Standard GBH: 10 years imprisonment.
-
Aggravated GBH: 14 years imprisonment (if involving domestic violence, victims over 60, or during a vehicle theft).
-
Assault on Public Officers: If the victim is a police officer or public officer, a mandatory minimum sentence of 12 months immediate imprisonment applies to adult offenders, which cannot be suspended.
What the Police Must Prove
-
The Injury: The victim suffered an injury meeting the GBH definition.
-
Causation: The accused caused that injury.
-
Unlawfulness: The act was not justified (e.g., self-defence).
Defences and Jurisdiction The primary defence is often that the injury does not meet the “grievous” threshold and should be downgraded to “Assault Occasioning Bodily Harm.” Other defences include Accident (the injury was not a foreseeable consequence) and Self-Defence.
GBH matters are “either-way” or indictable offences usually heard in the District Court of Western Australia.
