Whenever any person is acquitted upon the ground that, at the time at which he is alleged to have committed an offence, he was, by reason of unsoundness of mind, incapable of knowing the nature of the act alleged as constituting the offence, or that it was wrong or contrary to law, the finding shall state specifically whether he committed the act or not.

Landmark Judgements
Dahyabhai Chhaganbhai Thakkar v. State of Gujarat (1964):
While primarily dealing with Section 84 IPC, this landmark Supreme Court case laid down the fundamental principles for determining ‘unsoundness of mind’ in criminal cases, stating it must be ‘legal insanity’ (incapable of knowing the nature of the act or that it was wrong/contrary to law) at the time of the offence, forming the basis for an acquittal under Section 334 CrPC.
Sheralli Wali Mohammed v. State of Maharashtra (1972):
The Supreme Court reiterated that it is the mental condition at the time of the act which is material for the defence of insanity, not prior or subsequent mental states. This case reinforced the legal criteria for assessing unsoundness of mind that precedes an acquittal under Section 334 CrPC.
Bapu @ Gajraj Singh v. State of Rajasthan (2007):
This ruling by the Supreme Court further elucidated the approach to be taken by courts when a defence of insanity is raised under Section 84 IPC, emphasizing that the burden of proving legal insanity rests on the accused, and the court must carefully examine all circumstances to determine the state of mind at the time of the offence, which directly informs the specific finding required by Section 334 CrPC.
