Regina v Morris (Daryl): [2013] WLR (D) 140
“Where a defendant raised the defence of using reasonable force in the prevention of crime, under section 3(1) of the Criminal Law Act 1967, it would be necessary for the jury to focus first on what the defendant honestly believed were the facts before using their conclusions as to that belief to go on to decide whether the defendant had reasonable grounds for suspecting an offence was being committed and whether the force he used to prevent that crime had been reasonable.”
