[2001] UKPC 4

Under the McNaughten Rules it was clear that a defendant may be insane even if he intended to kill, if he did not know that what he was doing was wrong. An appeal against conviction was allowed where a judge had failed to make it plain that the defences of diminished responsibility and insanity could also apply where there was intention to kill or cause serious harm.
