Grievous Bodily Harm (GBH) is a serious criminal offence under Section 320 of the Criminal Code 1899 (Qld). It involves causing grave bodily harm, which can include life-threatening injuries, permanent damage, or serious disfigurement. A person can be charged whether the injury was caused intentionally or recklessly, and in some cases, the offence may arise even if the exact injury was not intended, as long as there was an intention to cause some harm.
