The definition of ABH was originally set out in R v Miller as 'any hurt or injury calculated to interfere with the health and comfort of the victim.' However, the definition of ABH is now set out in R v Chan-Fook; actual means not so trivial as to be 'wholly insignificant'; bodily means all parts, not limited to the harm of the skin, flesh and bones of the victim. It includes organs, nervous system and brain. It can include psychiatric injury but it does not include emotions or states of mind that are not an identifiable medical condition. Finally, harm means injury.
