Offences Against the Human Body
"Grievous" hurt is limited to: emasculation; permanent loss of sight in either eye or hearing in either ear; loss of a limb/joint; permanent destruction/impairment of a limb/joint's function; permanent facial/head disfigurement; fracture/dislocation of a bone or tooth; or any hurt endangering life or causing 15+ days of severe pain or inability to pursue ordinary activities.
This precisely defines the specific, more serious categories of injury that qualify as "grievous" hurt (carrying much harsher penalties than ordinary hurt) - a closed, specific list rather than a vague general standard, giving clear legal certainty about what counts.
A broken bone, permanent facial disfigurement, or an injury requiring more than two weeks of severe pain or incapacity all meet this section's specific, defined threshold for "grievous" hurt, triggering the harsher penalties that apply to it.
