Circumstantial evidence in forgery cases must form a complete chain; suspicion, conjecture, and uncorroborated testimony are insufficient.

In criminal prosecutions based on circumstantial evidence, guilt must rest on a complete chain of proved facts that excludes every reasonable hypothesis of innocence. Uncorroborated testimony from a seriously compromised witness is insufficient where no reliable independent material supports it, and suspicion cannot replace legal proof. Allegations of forgery and antedating must likewise be supported by affirmative evidence; conjecture from overwriting or internal inconsistencies is not enough. Inadmissible expert opinion cannot sustain a finding that a document was fabricated or typed later. The governing principle is that forgery and intent to injure must be established by reliable evidence, not inference alone.

Issues: (i) Whether the conviction for the alleged forgery of the tender could be sustained on circumstantial evidence and the uncorroborated testimony of a suspect witness. (ii) Whether Exhibit P-24 was proved to have been antedated and forged so as to sustain the conviction for forgery and intent to injure.

Issue (i): Whether the conviction for the alleged forgery of the tender could be sustained on circumstantial evidence and the uncorroborated testimony of a suspect witness.

Analysis: The circumstances relied upon by the prosecution had to be fully established and had to form a complete chain consistent only with guilt and excluding every reasonable hypothesis of innocence. The sole direct link depended on the testimony of a witness whose credibility was seriously impaired, since he was himself implicated in a forged document and his evidence was not corroborated by other reliable material. The remaining features of the tender were not of such an unusual or conclusive character as to compel the inference that the tender had been copied from another document. Suspicion, however strong, could not replace legal proof.

Conclusion: The conviction on the second charge could not stand and was set aside in favour of the appellants.

Issue (ii): Whether Exhibit P-24 was proved to have been antedated and forged so as to sustain the conviction for forgery and intent to injure.

Analysis: The record did not furnish affirmative evidence that the letter was written later than the date it bore. The internal contents of the letter were consistent with the date appearing on it, and the overwriting in the year was treated as no more than a circumstance giving rise to conjecture. The opinion evidence of experts regarding the typewriter was not admissible, and once that material was excluded, no reliable basis remained to hold that the document was typed on a later machine or fabricated. Read as a whole, the letter was not shown to have been made with intent to injure Amarnath or to create a false defence.

Conclusion: The conviction on the third charge could not stand and was set aside in favour of the appellants.

Final Conclusion: The appeal succeeded, the convictions under the surviving charges were quashed, and the appellants were acquitted.

Ratio Decidendi: In criminal cases resting on circumstantial evidence, guilt must be proved by a complete and conclusive chain of circumstances excluding every reasonable hypothesis of innocence, and a conviction cannot be sustained on conjecture, inadmissible opinion evidence, or the uncorroborated testimony of a witness whose credibility is seriously compromised.
