The offences of wounding and GBH are found under two separate sections of the Offences Against the Person Act 1861.GBH meaning grievous bodily harm. A conviction of wounding or GBH under S. 20 represents the lesser offence which carries a maximum penalty of 5 years imprisonment. Wounding and GBH under S.18 is a more serious offence and carries a maximum sentence of 25 years. There are common elements of the two offences. The main difference between the offences under s.18 and s.20 relate to the mens rea. Also the offence under s.20 is triable-either-way, whereas the offence of grievous bodily harm under s.18 is indictable.
"whosoever shall unlawfully and maliciously wound or inflict any grievous bodily harm on any other person, either with or without a weapon or instrument, shall be guilty of a misdeamenour"
Actus reus of the s.20 offence
Unlawfully
Wound
or inflict GBH
on another person
Unlawfully
Some wounding or GBH may be classed as lawful. This covers those who are acting in self defence or prevention of crime and in limited circumstances where the victim has consentedeg surgical interference and where the injury results from properly conducted games and sports. For more detailed review of the circumstances in which consent may operate see the lecture outline on consent. Lawful chastisement R v Hopley (1860) 2 F&F 202 (Case summary) or reasonable punishment of a child is not available to the offences of wounding or GBH (S.58 Children Act 2004).
Wound
A wound exists where there is a break in the continuity of the skin:
In the context of psychiatric injury, the word inflict simply means cause. There is no requirement of assault or battery or direct or indirect application of force:
The defendant must have the intention or be reckless as to the causing of some harm. There is no need for the prosecution to establish that they intended or was reckless as to causing serious harm:
"Whosoever shall unlawfully and maliciously by any means whatsoever wound or cause any grievous bodily harm to any person, with intent, to do some grievous bodily harm to any person, or with intent to resist or prevent the lawful apprehension or detainer of any person, shall be guilty of felony."
Actus reusof the s.18 offence
Unlawfully
wound or cause GBH
on any person
Since the decision in Burstow there is little difference between in the actus reus under s.20 and s.18. The one difference is that the offence under s.20 must be committed on another person whereas s.18 can be committed on any person and thus would cover those who intentionally wound or inflict GBH on themselves.
Mens rea
The mens rea under s.18 requires either:
Intention to cause GBH or
Intention to resist or prevent the lawful detainer of any person.
