Bench: Justice M.M. Sundresh and Justice Satish Chandra Sharma (author)

Introduction

Can an investigating officer who collected call detail records from a telecom company issue a valid Section 65B certificate for those records?

Can courts acquit all accused in a multi-accused conspiracy murder case simply because the High Court disagrees with the trial court's assessment of eyewitness evidence?

The Supreme Court answered both questions on 19 May 2026. In State of Tamil Nadu v. Ponnusamy, the Court restored the conviction of nine accused persons for the conspiracy and murder of Dr. Subbiah, a Chennai physician. In doing so, it laid down important principles on the admissibility of electronic evidence under Section 65B of the Indian Evidence Act (now Section 63 of the Bharatiya Sakshya Adhiniyam, BSA, 2023), the standard of appellate review in criminal cases, approver evidence, and the constitutional limit on crime scene re-enactment under Article 20(3).

Background: The Murder of Dr. Subbiah

Dr. Subbiah was a respected physician working at Billroth Hospital, Raja Annamalaipuram, Chennai.

On 14 September 2013, at approximately 5:00 PM, Dr. Subbiah finished his shift and left the hospital. As he came out onto 1st Main Road, he was attacked by three men wielding sickles. He sustained multiple injuries on his head, neck, shoulder, and right forearm. He was initially taken to a nearby hospital but, as his condition worsened, he was shifted back to Billroth Hospital, Aminjikarai, where he succumbed to his injuries on 23 September 2013.

The motive was a long-standing land dispute. The prosecution's case was that a criminal conspiracy involving advocates, real-estate interests, and hired henchmen was formed to eliminate the doctor. The conspiracy involved:

• The principal accused (A1 and A2): advocates and interested parties in the land dispute
• Financiers and coordinators (A3 to A7): who arranged funds and logistics
• The actual assailants (A8, A9, and A10 — later the approver PW12)

The case was tried in a Special Court, which convicted all nine accused (ten were tried; A10 turned approver). Several accused were sentenced to death.

The Madras High Court's Acquittal

The Madras High Court, hearing the appeals of the convicted accused, set aside all convictions and acquitted everyone.

The High Court's primary reasons were:

• Eyewitness testimony (PW2 and PW3) was inconsistent and unreliable.
• The call detail records (CDRs) were not properly proved under Section 65B of the Indian Evidence Act.
• The approver's testimony (PW12) was inconsistent with their earlier statement and lacked corroboration.
• CCTV footage evidence was inadmissible due to chain-of-custody defects.
• Extra-judicial confession by A6 to PW7 lacked corroboration.

The State of Tamil Nadu and the complainant filed criminal appeals before the Supreme Court.

What the Supreme Court Found and Held

The Supreme Court, authored by Justice Satish Chandra Sharma, conducted a detailed re-appreciation of the entire evidence and set aside the High Court's acquittal in respect of nine accused persons.

The judgment's most important legal pronouncements fall under six heads.

1. The CDR Admissibility Issue: Section 65B Cannot Be Fulfilled by the Recipient

This is the most directly exam-relevant holding.

Call Detail Records (CDRs) showing that the accused were in contact with each other before and around the time of the murder were produced by PW45, the investigating officer who had collected the CDRs from the telecom companies by email.

PW45 had issued a Section 65B certificate in support of these CDRs.

Both the High Court and the Supreme Court found this to be legally deficient.

The Supreme Court held:

As per Section 65-B of the Evidence Act, CDRs could have been proved only by a person having lawful control over the computer that produced the electronic record and therefore, a certificate under Section 65-B ought to have been filed by the concerned nodal officer of the telecom company.

The three specific failures were:

• PW45 received the CDRs from telecom companies but was not the person "in control of the system" that generated them.
• The telecom company's nodal officers were never examined as witnesses, leaving the chain of custody broken.
• The CDRs were produced in Excel format, which is an editable format susceptible to manipulation.

The Court confirmed: <cite index="32-1">Section 65B is not a ritual of paper compliance. The certificate must come from a competent source connected with the generation of the electronic record, and proof must also preserve continuity from source to investigator to court.</cite>

However, the Court added a crucial qualification that prevented this from being fatal to the case: the CDRs had been relied upon by the prosecution only as corroborative material, not as the foundation of guilt. Since the conviction rested on sufficient oral, direct, and other circumstantial evidence, the rejection of the CDRs did not affect the final outcome.

This is an important practical lesson: improperly proved electronic evidence that serves only a corroborative function may be rejected without overturning the entire conviction, as long as other sufficient independent evidence supports the finding of guilt.

2. The Standard of Appellate Review: No "Loose Acquittals"

The Court delivered one of its most memorable statements on the standard of criminal proof and the limits of appellate re-appreciation.

It held that the phrase "beyond reasonable doubt" does not mean any and every doubt. It means:

A doubt which is so strong and reasonable that it effectively creates space for an alternate theory in the mind of the Judge. Unsurprisingly, ordinary doubts are bound to emerge in a case where the transaction and witnesses are scattered across a wide spectrum. The job of a criminal court is not to order loose acquittals by entertaining such vague and ordinary doubts, convoluted theories and suppositions. A loose acquittal of a guilty person is as dangerous as the conviction of an innocent

The High Court had committed the error of applying an "unduly sceptical standard" to consistent eyewitness accounts and had substituted its own re-appreciation of evidence without identifying specific grounds for interference. This was held to be beyond the proper scope of appellate re-appreciation in an appeal against conviction.

3. Eyewitness Testimony: PW2 and PW3 Were Credible

The Supreme Court carefully reviewed the evidence of PW2 and PW3, who were eyewitnesses to the sickle attack outside Billroth Hospital.

The Court found that their testimonies were consistent in material particulars. Minor variations in cross-examination, the normal result of recalling a traumatic event in a public place, were not grounds to discard entirely credible accounts. The witnesses had no prior enmity with the accused and had no reason to falsely implicate them.

The High Court's wholesale rejection of these witnesses was held to be erroneous. The Supreme Court restored the finding that the attack on Dr. Subbiah was established by direct eyewitness evidence.

4. Approver Evidence: PW12's Testimony Must Be Read with Corroboration

PW12 was originally A10, one of the three direct assailants. After arrest, he was tendered a pardon under the CrPC and turned approver. He gave a detailed account of the conspiracy, including how the accused planned the murder, the money that changed hands, and the manner of the attack.

The High Court had dismissed PW12's evidence on the ground that it was inconsistent with his earlier statement under Section 161 CrPC and his confession.

The Supreme Court applied the classic rule on approver evidence:

• An approver's testimony is not inherently inadmissible.
• It is a species of accomplice evidence that must be approached with caution and accepted only when corroborated in material particulars by independent evidence.
• Minor inconsistencies between a Section 161 statement made to police under potential pressure and later courtroom evidence do not destroy the approver's credibility. The relevant test is whether the core of the approver's account is independently corroborated.

The Court found that PW12's account of the conspiracy, the payments, and the attack was independently corroborated by the money trail evidence, recovery evidence under Section 27 IEA (Section 23 BSA), and the eyewitness accounts of the attack itself.

5. Conspiracy Evidence: Secrecy Does Not Make Direct Proof Impossible

The Court addressed a recurring argument in conspiracy cases: that since conspiracies are hatched in secrecy, any evidence of them is necessarily circumstantial and therefore weak.

The Court held: Conspiracies are generally hatched in secrecy, however, it does not mean that direct evidence of conspiracy is an impossibility, or that such evidence would get rejected on this notion alone.

The conspiracy in this case was established through a combination of:

• The financial motive (the land dispute and the threat the doctor posed to the accused's land interests)
• The money trail showing payments from principal accused to intermediaries and ultimately to the assailants
• PW12's (the approver's) direct account of the conspiracy meetings
• Recovery of weapons under Section 27 IEA at the instance of A8 and A9
• Eyewitness identification of A8 and A9 as two of the three attackers

6. Crime Scene Re-Enactment and Article 20(3)

The Court was also asked to decide whether crime scene re-enactment by the accused constitutes testimonial compulsion violating Article 20(3)'s right against self-incrimination.

The Court held that a broad re-enactment of a crime scene does not per se amount to testimonial compulsion or self-incrimination.

The test is: does the act require the accused to merely perform a physical act or demonstrate something, without giving personal testimony? If so, it is constitutionally valid. If it compels the accused to disclose incriminating information from their personal knowledge, it would be impermissible.

In this case, the accused were directed to demonstrate their physical movements or positions at the crime scene. This was treated as a physical demonstration, not as personal testimony.

7. CCTV Evidence Rejected: Chain of Custody Defects

A pen drive containing a backup copy of CCTV footage was also rejected. The problems were:

• It contained a truncated copy of the footage.
• The cloned copies of the CCTV footage were not properly generated.
• The gait analysis conducted on the footage was not admitted as valid scientific evidence.

Again, the Court held that rejection of this evidence did not affect the conviction because sufficient direct eyewitness evidence identified A8 and A9.

The Final Orders

The Supreme Court restored the trial court's convictions for nine accused persons. However, since the State itself had conceded that the death sentences should not be maintained in the light of overall circumstances, the Court converted all death sentences to life imprisonment.

For the two elderly accused with limited roles (A1 and A2), the Court suspended their sentences for eight weeks to enable them to approach the Governor of Tamil Nadu under Article 161 of the Constitution for pardon.

All other convicted accused were directed to surrender before the trial court within two weeks.

Section 65B IEA to Section 63 BSA: What Changed

Section 65B of the Indian Evidence Act, 1872 has been replaced by Section 63 of the Bharatiya Sakshya Adhiniyam (BSA), 2023 from 1 July 2024.

The core requirements are the same under both provisions:

• A certificate is required to prove electronic records.
• The certificate must be issued by the person responsible for the operation of the relevant device.
• The certificate must identify the electronic record and state that it was produced in the ordinary course of activities.
• The competent person must sign the certificate.

The Ponnusamy ruling applies equally under Section 63 BSA: the investigating officer who merely receives an electronic record cannot issue the required certificate. Only the person in lawful control of the system that generated the record can validly certify it.

Why This Judgment Matters

It Reinforces the True Meaning of the Section 65B Certificate

The judgment makes clear that the Section 65B certificate is not a paperwork formality. It is a substantive evidentiary requirement. The person who signs it must be the person who had lawful control over the system that generated the record, not merely someone who received the record from that system.

It Corrects Overuse of Acquittal Power

The High Court's acquittal of all nine accused was held to be a product of excessively sceptical evidence re-appreciation. The Supreme Court's characterisation of "loose acquittals" as being as dangerous as wrongful convictions reinforces that appellate courts must respect consistent, credible trial court findings.

It Gives a Practical Approach to CDR Non-Admissibility

The judgment shows that improperly proved CDRs can be rejected without destroying an otherwise well-proved case. Where CDRs are only corroborative and the conviction rests on independent evidence, their rejection does not mandate acquittal.

It Settles the Crime Scene Re-Enactment Question

The Article 20(3) holding on re-enactment, distinguishing physical demonstration from testimonial compulsion, gives investigators and courts a clear test for when re-enactment evidence can be used without violating the right against self-incrimination.

Conclusion

State of Tamil Nadu v. Ponnusamy is a judgment that refuses to allow the criminal justice system to fail a murder victim because of evidentiary technicalities on one hand, or to paper over foundational certificate defects on the other. The CDRs were rightly rejected. The conviction was rightly restored on other, properly proved evidence.

Frequently Asked Questions

Q1. What is the State of Tamil Nadu v. Ponnusamy case about?

It is a 2026 Supreme Court judgment restoring the convictions of nine accused persons in the conspiracy murder of Dr. Subbiah, a Chennai physician, outside Billroth Hospital on 14 September 2013. The Madras High Court had acquitted all accused. The Supreme Court set aside the acquittal and converted death sentences to life imprisonment, holding that the High Court had applied an unduly sceptical standard in re-appreciating the evidence.

Q2. What did the Court decide on the Section 65B certificate for CDRs?

The Court held that a Section 65B certificate for Call Detail Records (CDRs) must be issued by the person who has lawful control over the computer system that generated the records, meaning the telecom company's nodal officer. An investigating officer who merely received the CDRs by email from the telecom company does not have the required lawful control and cannot issue a valid Section 65B certificate. The CDRs in this case were therefore rightly rejected.

Q3. Does rejection of CDRs always result in acquittal?

 No. The Court held that where CDRs are relied upon only as corroborative material and not as the foundation of the prosecution's case, their rejection does not necessarily lead to acquittal. In this case, the convictions were maintained on independent oral evidence (eyewitnesses), approver testimony, money trail, and recoveries under Section 27 IEA, without needing the CDRs.

Q4. What is the BSA equivalent of Section 65B IEA?

 Section 65B of the Indian Evidence Act, 1872 has been replaced by Section 63 of the Bharatiya Sakshya Adhiniyam (BSA), 2023, which came into force on 1 July 2024. The core requirement remains the same: a certificate from the person in lawful control of the system that produced the electronic record is required for the record to be admissible.

Q5. What did the Court say about crime scene re-enactment and Article 20(3)?

 The Court held that a broad re-enactment of a crime scene does not per se amount to testimonial compulsion under Article 20(3). The test is whether the act requires the accused to give personal testimony disclosing incriminating knowledge, or merely to perform a physical demonstration. Physical demonstrations, such as showing one's movements at the crime scene, are constitutionally permissible. Compelling an accused to disclose personal knowledge would not be.
