Summary
The Supreme Court restored an acquittal under Section 84 IPC after the High Court substituted its assessment of the insanity defence without finding the trial view perverse. Medical history, psychiatric evidence and abnormal conduct around the assault supported the trial court’s plausible conclusion. Although the fatal attack was established, legal responsibility required separate examination. The prosecution’s burden of proving the offence remained distinct from the accused’s civil-standard burden concerning the exception.
Issues
- Whether the evidence supported the trial court’s application of Section 84 IPC.
- Whether the High Court could reverse a plausible acquittal merely by reappraising the evidence.
Provisions considered
- Section 84, Indian Penal Code, 1860The relevant incapacity must exist when the act is done. Psychiatric history, medical testimony and contemporaneous abnormal behaviour supported the trial court’s finding of legal insanity here. (¶¶ 15, 16, 17, 18, 19, 20, 21, 22, 23, 25, 26)
- Sections 4, 101 and 105, Indian Evidence Act, 1872The accused’s burden to establish the exception is no higher than the civil standard. Independently, evidence insufficient to establish the exception conclusively may still create reasonable doubt about an offence ingredient, whose proof remains the prosecution’s burden. (¶¶ 20, 21)
Held
- The fatal assault was proved through eyewitness and medical evidence, but whether the accused lacked the legally relevant capacity at that time remained a separate question. Section 84 concerns legal insanity, not a diagnosis alone. (¶¶ 8, 9, 10, 11, 12, 13, 14, 19, 22)
- Earlier psychiatric treatment and a relapseable disorder were corroborated by medical evidence. His conduct during and immediately after the occurrence, including apparent lack of comprehension of his acts, supported the trial court’s conclusion; it was neither unsupported nor perverse. (¶¶ 15, 16, 17, 18, 25, 26)
- The prosecution must prove every offence ingredient beyond reasonable doubt throughout. The accused can rebut the presumption against the exception on the civil standard; even evidence that does not fully establish the exception may require acquittal if it leaves reasonable doubt concerning mens rea or another essential ingredient. (¶¶ 20, 21)
- An appellate court should not replace a plausible acquittal with a different view merely on reappreciation of the evidence. The High Court identified no perversity sufficient to justify overturning this supported acquittal. (¶¶ 24, 25, 26, 27)
Result
Appeals allowed. High Court conviction and sentence set aside and trial acquittal restored. Appellant acquitted of the Section 302 charge and directed to be released immediately unless required in another case.
