R.M. Malkani v. State of Maharashtra

This is the case in which a scientifically produced record decided a criminal appeal, and it is the one to use when the examiner asks what use a recording can be put to. N. Sri Rama Reddy v. V.V. Giri establishes that a tape-recorded conversation is admissible. Malkani shows the recording doing real work: supplying the corroboration that oral testimony was held to need.

It is therefore the bridge between the documentary module and the forensic module. A recording is a machine-made record; its value depends on the circumstances in which the machine was used, and those circumstances have to be proved.

The accused, who appealed to the Supreme Court against his conviction, was the coroner of Bombay. A doctor running a nursing home operated on a patient who afterwards died. Being a post-operation death, it became the subject of a post-mortem and inquest. The coroner persuaded the doctor to pay him a sum of money if he wanted the report to be favourable to him.

The payment was arranged to be made through another doctor, and the final meeting for the purpose was to be settled by a telephone call from that other doctor's house. The police commissioner was called with the tape-recording mechanism, which was connected to the doctor's telephone, and the incriminating conversation was recorded in the presence of the police officer.

The Bombay High Court held that the testimony of the two doctors required corroboration, and that the tape amply corroborated it. The decision was upheld by the Supreme Court.

Step one — the recording is a document. The word document is not to be construed restrictively; it means something which shows or teaches, and is evidential or informative in character. There is no reason in principle why the recording of the human voice in a permanent or semi-permanent manner should not be a document, provided it furnishes information.

Step two — the medium determines admissibility, the circumstances determine weight. The recording carried weight here because of how it came into existence: the mechanism was connected in the presence of the police commissioner, and the conversation was recorded in the presence of the officer. The provenance is what allowed the court to treat the tape as reliable corroboration rather than as an item requiring corroboration itself.

Step three — corroboration is the function it performed. The oral evidence of the two doctors was found to need support; the tape supplied it. That is the classic role of scientific evidence in a criminal trial — it does not usually stand alone, it tests and confirms human testimony.

Step four — the constitutional point does not arise on these facts. Statements recorded of an accused without any duress, with or without his knowledge, are not hit by Article 20(3). Recording is not compulsion to be a witness.

Use Malkani for the proposition that a tape recording may corroborate oral testimony, and as the illustration in any question about electronic or scientific evidence and its evidentiary value.

Then state the modern law, because an answer confined to the 1872 position is incomplete. BSA s. 61 forbids denying admissibility to a record merely because it is electronic or digital, a provision with no ancestor in the old Act. BSA s. 57, with its Explanations, makes electronic records primary evidence. BSA s. 63 governs the admissibility of computer output, and under s. 63(4) the certificate must accompany the record at each instance of submission and must be signed by the person in charge and an expert — a double change from the old s. 65B(4). Sections 57 and 63 must be read together, not treated as alternatives. Corroboration by a former statement is now BSA s. 160 (IEA s. 157).

The case does not hold that a recording is self-proving. Its authenticity, the identity of the voices and the absence of tampering must all be established, and where they are not the tape has no value. Nor does it decide the legality of the interception, which is governed by other law.
