Bapu @ Gajraj Singh vs State of Rajasthan - Supreme Court Case

 Bapu @ Gajraj Singh vs State of Rajasthan - Supreme Court Case Summary of Leading Case -

On 4th June, 2007, a two Judges Bench in Bapu @ Gajraj Singh vs State of Rajasthan [Criminal Appeal No.1313 of 2006] held that “every person, who is mentally diseased, is not ipso facto exempted from criminal responsibility.” “In dealing with cases involving a defence of insanity, distinction must be made between cases, in which insanity is more or less proved and the question is only as to the degree of irresponsibility, and cases, in which insanity is sought to be proved in respect of a person, who for all intents and purposes, appears sane.”

The Bench held that “under Section 84 IPC, a person is exonerated from liability for doing an act on the ground of unsoundness of mind if he, at the time of doing the act, is either incapable of knowing (a) the nature of the act, or (b) that he is doing what is either wrong or contrary to law. The accused is protected not only when, on account of insanity, he was incapable of knowing the nature of the act, but also when he did not know either that the act was wrong or that it was contrary to law, although he might know the nature of the act itself. He is, however, not protected if he knew that what he was doing was wrong, even if he did not know that it was contrary to law, and also if he knew that what he was doing was contrary to law even though he did not know that it was wrong. The onus of proving unsoundness of mind is on the accused. But where during the investigation previous history of insanity is revealed, it is the duty of an honest investigator to subject the accused to a medical examination and place that evidence before the Court and if this is not done, it creates a serious infirmity in the prosecution case and the benefit of doubt has to be given to the accused. The onus, however, has to be discharged by producing evidence as to the conduct of the accused shortly prior to the offence and his conduct at the time or immediately afterwards, also by evidence of his mental condition and other relevant factors.”

“Section 84 embodies the fundamental maxim of criminal law, i.e., actus non reum facit nisi mens sit rea” (an act does not constitute guilt unless done with a guilty intention). In order to constitute an offence, the intent and act must concur; but in the case of insane persons, no culpability is fastened on them as they have no free will (furios is nulla voluntas est)”, said the Bench. However, the Bench held that “the mere fact that an accused is conceited, odd irascible and his brain is not quite all right, or that the physical and mental ailments from which he suffered had rendered his intellect weak and had affected his emotions and will, or that he had committed certain unusual acts, in the past or that he was liable to recurring fits of insanity at short intervals, or that he was subject to getting epileptic fits but there was nothing abnormal in his behaviour, or that his behaviour was queer, cannot be sufficient to attract the application of this section.”
