Voice identification evidence needs strict safeguards; unverified taped conversation and weak recovery could not sustain conviction.

Suspicious voice identification and an unverified tape-recorded conversation could not, without strict safeguards, sustain a conviction. The Court emphasised that voice evidence requires clear proof of the speaker's identity, the recording's accuracy, absence of tampering, and reliable custody of the cassette; taped conversation is only corroborative and cannot stand alone. It found material infirmities in the identification process, no dependable linkage between the appellant and the mobile numbers relied on, and weak recovery evidence from a place not shown to belong to the appellant. The conviction and sentence were set aside, and the appellant received the benefit of doubt.

Issues: Whether the appellant's conviction could be sustained primarily on the basis of voice identification evidence and the alleged tape-recorded conversation, along with the recovery evidence relied upon by the prosecution.

Analysis: The prosecution case rested substantially on identification of voices in a recorded conversation and on alleged recovery of a revolver. The Court noted that voice identification is a fragile form of evidence and requires strict safeguards, including proper identification of the speaker, proof of accuracy of the recording, exclusion of tampering, and reliable custody of the cassette. It further held that tape-recorded conversation is, at best, corroborative and cannot by itself sustain a conviction in the absence of dependable independent evidence. The Court found material infirmities in the manner in which the voice identification was conducted, the absence of adequate safeguards, the lack of reliable linkage between the appellant and the mobile numbers attributed to him, and the weak evidentiary value of the recovery from a place not belonging to the appellant.

Conclusion: The conviction could not be sustained; the appellant was entitled to the benefit of doubt and the conviction and sentence were set aside.

Ratio Decidendi: A conviction cannot rest on suspect voice identification and an unverified taped conversation unless the recording's authenticity, speaker identification, and integrity are proved with strict safeguards beyond reasonable doubt.
