Circumstantial evidence demands a complete chain of proof before reversing an acquittal; unsupported inference fails.

In a conviction resting solely on circumstantial evidence, every incriminating link had to be proved beyond reasonable doubt, and reversal of an acquittal was not justified where the prosecution failed to establish the alleged escape route and other material circumstances. The Court held that the High Court's inference on the manner of escape was unsupported by evidence, and the accused had not been given a proper opportunity under Section 313 CrPC to explain that circumstance. Suspicion could not substitute for proof, the presumption of innocence was reinforced after acquittal, and the appellants were entitled to the benefit of doubt.

Issues: Whether the conviction recorded by the High Court on circumstantial evidence, after reversing an acquittal, could be sustained when the prosecution had not proved the complete chain of circumstances and the alleged escape route of the assailant.

Analysis: The case rested entirely on circumstantial evidence, so every incriminating link had to be proved. The Court found that the prosecution had not established the vital circumstance that the appellant No. 1 could have committed the offence, closed the room, and escaped through the alleged opening or window. The High Court's reasoning on the manner of escape was not supported by evidence, nor had the accused been given an opportunity under Section 313 of the Code of Criminal Procedure, 1973 to explain that circumstance. The Court reiterated that suspicion, however strong, cannot replace proof, that benefit of doubt belongs to the accused, and that the presumption of innocence is strengthened after an acquittal.

Conclusion: The conviction could not be sustained and the appellants were entitled to the benefit of doubt.

Ratio Decidendi: In a case based solely on circumstantial evidence, reversal of an acquittal is impermissible unless the prosecution proves all material links in the chain beyond reasonable doubt and the accused is afforded a fair opportunity to explain incriminating circumstances.
