Palmer v The Queen: PC 23 Nov 1970

It is a defence in criminal law to a charge of assault if the defendant had an honest belief that he was going to be attacked and reacted with proportionate force: ‘If there has been an attack so that defence is reasonably necessary, it should be recognised that a person defending himself cannot weigh to a nicety the exact measure of necessary defensive action. If a jury is of the opinion that in a moment of unexpected anguish the person attacked did only what he honestly and reasonably thought was necessary, that should be regarded as most potent evidence that only reasonably defensive action was taken.’
Jamaica – The defendant appealed against his conviction for murder, arguing self defenec.
Held: After setting out the elements of the defence of self-defence, Lord Morris of Borth-y-Gest said: ‘if the prosecution have shown that what was done was not done in self-defence then that issue is eliminated from the case. If the jury consider that the accused acted in self-defence or if the jury are in doubt as to this then they will acquit. The defence of self-defence either succeeds so as to result in an acquittal or it is disproved in which case as a defence it is rejected.’
