Insanity defence under Section 84 IPC failed where evidence proved the accused caused the fatal injuries and knew his acts.

The prosecution proved that the accused inflicted the fatal injuries on his wife and child because he was found at the scene with a bloodstained chopper, the room was chained from inside, and the medical evidence showed ante-mortem injuries sufficient in the ordinary course of nature to cause death. The plea of insanity under Section 84 IPC failed because the defence did not establish that, at the time of the act, unsoundness of mind deprived him of the capacity to know the nature of the act or that it was wrong or contrary to law. The conviction and sentence were upheld.

Issues: (i) Whether the accused caused the fatal injuries to his wife and child; (ii) whether the accused had established that, at the time of the occurrence, he was of unsound mind so as to attract the defence under Section 84 of the Indian Penal Code, 1860.

Issue (i): Whether the accused caused the fatal injuries to his wife and child.

Analysis: The evidence of the police witnesses placed the accused at the scene with a bloodstained chopper, while his wife and child were found inside the room with bleeding injuries. The room was chained from inside and there was no evidence of access by any other person. The medical evidence showed that the injuries were ante-mortem and sufficient in the ordinary course of nature to cause death.

Conclusion: The accused caused the fatal injuries.

Issue (ii): Whether the accused had established that, at the time of the occurrence, he was of unsound mind so as to attract the defence under Section 84 of the Indian Penal Code, 1860.

Analysis: The defence evidence of alleged temporary insanity was not supported by the doctors said to have treated him. On the other hand, the evidence showed that he had been working normally shortly before the and was found in a normal condition soon after the occurrence. The legal test under Section 84 requires proof that, by reason of unsoundness of mind, the accused was incapable of knowing the nature of the act or that it was wrong or contrary to law. The surrounding circumstances did not raise a reasonable doubt on that basis.

Conclusion: The defence of insanity failed.

Final Conclusion: The conviction and sentence were upheld because the prosecution proved that the accused caused the deaths and the plea of unsoundness of mind was not established.

Ratio Decidendi: To succeed under the insanity exception, the accused must show that, at the time of the act, unsoundness of mind deprived him of the capacity to know the nature of the act or its wrongfulness; absent such proof, concurrent findings that the accused committed the act with mens rea will not be disturbed.
