Wounding and infliction of GBH with intent

Question 1

Actus reus

Answer 1

Same as section 20: wounding or GBH

Question 2

Intent to cause GBH; intent to prevent a lawful arrest

Answer 2

R v O’Donnell: must be intention to cause GBH; intention to wound is not enough
R v Bentley: not a defence to show that D thought the arrest was unlawful (although if the arrest was not lawful the offence will not be committed)
