(Law) (in English law) a set of rules established by the case of Regina v.

In England the McNaghten Rules (1843) laid down the law relating to insanity as it still is now: the defendant must show that he was, at the time of the offence, `labouring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing, or, if he did know it, did not know he was doing what was wrong.
