SC on Circumstantial Evidence and Electronic Records: Analysis of Pooranmal v. State of Rajasthan (2026 INSC 217)

Executive Summary

The Supreme Court in Pooranmal v. State of Rajasthan (2026 INSC 217) set aside the concurrent conviction of the appellant for murder and destruction of evidence, underscoring the rigorous standards applicable to cases based purely on circumstantial evidence. The judgment also reinforces the mandatory requirement of a certificate under Section 65-B of the Indian Evidence Act, 1872 (now Section 63 of the Bharatiya Sakshya Adhiniyam, 2023) for admissibility of electronic records such as call detail records, and stresses the need to prove an unbroken chain of custody for forensic exhibits.[1]

Factual Background

The prosecution case alleged that the appellant, Pooranmal, along with co-accused Ladu Lal, murdered Aruna, wife of Ladu Lal, in the latter’s house during the intervening night of 2 and 3 March 2010 in Bhilwara, Rajasthan. Initially, it was Ladu Lal himself who lodged the written report, stating that he had been sleeping with his son in one room while Aruna slept in an adjacent room, that his room was found bolted from outside in the night, and that when neighbours and a police constable helped open the house, Aruna was found dead with injuries and signs of struggle, with about four lakh rupees allegedly missing from an almirah.[1]

On this report, FIR No. 28 of 2010 was registered under Section 460 IPC (corresponding to Section 331(8) of the Bharatiya Nyaya Sanhita, 2023), and usual investigation followed, including inquest and post-mortem. Suspicion later turned towards Ladu Lal during interrogation, leading to his arrest and a disclosure statement in which he implicated the appellant; on this basis, the police allegedly recovered a blood-stained shirt and currency notes totalling 46,000 rupees from the appellant, and collected call detail records showing frequent communication between the two accused around the time of the incident.[1]

Procedural History

After investigation, a chargesheet was filed against both accused for offences under Sections 302/34 and 201 IPC (now Sections 103(1)/3(5) and 238 BNS), and the case was committed to the Court of the Additional Sessions Judge (Women Atrocities Cases), Bhilwara. The trial court convicted both accused, sentencing them to life imprisonment and fine for murder, and seven years’ rigorous imprisonment and fine for the Section 201 IPC charge, with sentences to run concurrently.[1]

The High Court of Rajasthan at Jodhpur dismissed their common appeal, affirming the conviction and sentence. Co-accused Ladu Lal’s subsequent special leave petition was dismissed in limine by the Supreme Court in 2022, whereas the present appeal by Pooranmal, filed through legal aid with a delay of 2,749 days, was entertained in 2026 because the case against him rested on a distinct evidentiary footing, primarily on recoveries and call detail records, unlike the additional reverse-burden element against Ladu Lal under Section 106 Evidence Act.[1]

Issues Before the Supreme Court

The Supreme Court framed its analysis around whether the prosecution had succeeded in establishing a complete and coherent chain of circumstances sufficient to sustain the conviction of the appellant in a case purely based on circumstantial evidence. Specifically, the Court examined three incriminating circumstances relied upon by the prosecution: (i) call detail records showing frequent contact between the appellant and Ladu Lal; (ii) recovery of a blood-stained shirt at the instance of the appellant, allegedly bearing the same blood group as the deceased; and (iii) recovery of currency notes of 46,000 rupees allegedly paid by the co-accused to the appellant for committing the murder.[1]

Ancillary legal issues arose as to: (a) the reliability and incriminating nature of monetary recoveries when the amount and linkage to the crime are doubtful; (b) the evidentiary value of a forensic (FSL) report when the chain of custody of exhibits is compromised; and (c) the admissibility of electronic evidence (CDRs) in the absence of a proper Section 65-B certificate under the Evidence Act.[1]

Legal Framework on Circumstantial Evidence

The Court reiterated that the law governing cases based purely on circumstantial evidence is well-settled and referred to the classic formulation in Sharad Birdhichand Sarda v. State of Maharashtra, which lays down the five “golden principles” for sustaining a conviction on circumstantial evidence. These require that the circumstances be fully and firmly established, consistent only with the hypothesis of guilt, of a conclusive nature, excluding every possible hypothesis consistent with innocence, and forming a chain so complete as to leave no reasonable ground for a contrary conclusion.[1]

Applying these principles, the Court emphasised that each individual circumstance must be proved by cogent and admissible evidence, and that even then, they must collectively constitute an unbroken chain pointing unerringly towards the guilt of the accused; conjectures or suspicious facts, however grave, cannot substitute for legally admissible and reliable evidence.[1]

Assessment of the Recovery of Currency Notes

The first circumstance scrutinised by the Court was the alleged recovery of 46,000 rupees from the appellant’s house pursuant to his disclosure statement under Section 27 Evidence Act (now reflected in the proviso to Section 23 BSA). The investigating officer deposed in examination-in-chief that, as per the disclosure, the appellant had received 46,000 rupees from Ladu Lal as part payment for executing the murder, and that this exact sum was recovered and seized under memo Ex. P-13.[1]

In cross-examination, however, the officer conceded that while the chit on the packet (Ex. P-52) recorded the amount as 46,000 rupees, when the notes were actually counted in court, the total came to 46,145 rupees, and there was no mention anywhere of the extra 145 rupees. This discrepancy cast a serious doubt on the very factum and integrity of the alleged recovery, prompting the Court to hold that the recovery of currency notes itself was under a “grave cloud of doubt”.[1]

The Court further held that, even assuming arguendo that some amount was recovered, mere possession of currency in the stated circumstances, without cogent evidence to establish a clear nexus between the seized amount and the alleged consideration for the murder, could not be treated as an incriminating circumstance against the appellant. Accordingly, the trial court erred in treating this recovery as a decisive link in the chain of circumstances.[1]

Assessment of the Recovery of Blood-stained Shirt

The second incriminating circumstance was the recovery of a shirt allegedly worn by the appellant during the incident, said to be blood-stained and later found by FSL analysis to contain blood of group O, matching that of the deceased. The shirt was recovered from an iron box at the appellant’s residence pursuant to his disclosure statement (Ex. P-43) and seized under memo Ex. P-9.[1]

The Court approached this recovery with scepticism, noting first the inherent improbability in the narrative: the appellant remained at large from the time of the incident until 4 March 2010 and, if guilty, would more naturally have destroyed or washed the incriminating garment instead of carefully preserving it, unwashed, in a box in his own home. This behaviour was considered highly unnatural and inconsistent with ordinary human conduct, thereby undermining the plausibility of the prosecution’s version.[1]

More importantly, the Court held that the FSL report (Ex. P-49) linking the shirt’s blood group to that of the deceased could not be relied upon in the absence of proof of an unbroken chain of custody of the seized articles. Forensic results are only as good as the integrity of the samples tested, and the prosecution bears the burden of demonstrating that the exhibits remained sealed, untampered and properly logged from seizure until examination.[1]

Chain of Custody and Forensic Evidence

To test the chain of custody, the Court closely examined the evidence of the malkhana in-charge (PW-19) and the carrier constable (PW-16), juxtaposing it with the malkhana register entries (Ex. P-37 and Ex. D-3). PW-19 stated that blood-stained tissues and the shirt were deposited in the malkhana on 6 March 2010, and that on 7 March 2010 a sealed bag containing 46 notes of 1,000 rupees each was also deposited; these, together with other exhibits, were ostensibly sent with PW-16 to the SP office on 15 March 2010 but returned because the FSL forwarding letter had not yet been prepared, after which they were re-deposited in the malkhana.[1]

PW-16, on the other hand, deposed that he only carried the articles on 18 March 2010 and deposited them at the FSL on 19 March 2010, denying knowledge of any earlier movement on 12–15 March. The malkhana register entry (Ex. D-3), however, recorded that the articles had in fact been taken out and sent towards FSL as early as 12 March 2010, which directly contradicted the oral testimony of both witnesses.[1]

The Court found that the prosecution had utterly failed to explain the discrepancies surrounding the earlier dispatch and return of the muddamal articles, and that the lack of a clear, credible narrative as to when, how and why the exhibits moved in and out of custody fatally undermined the safety of the chain of custody. Relying on its earlier decision in Karandeep Sharma v. State of Uttarakhand, the Court reiterated that, for DNA or FSL reports to be accepted as reliable, the prosecution must prove through link evidence that the samples were properly sealed, preserved and transmitted in a self-same condition; any serious doubt in this chain renders the report worthless.[1]

Consistent with this approach, the Court also cited Allarakha Habib Memon v. State of Gujarat, where it had held that even if an FSL report shows that blood on a recovered weapon matches the deceased’s blood group, such a finding, by itself and in isolation, cannot sustain a conviction unless connected to other dependable evidence establishing the weapon’s use in the crime. Applying this line of authority, the Court concluded that, in the present case, the FSL report (Ex. P-49) was a “worthless piece of paper” and could not be treated as an incriminating circumstance against the appellant.[1]

Admissibility of Call Detail Records and Section 65-B

The third circumstance against the appellant comprised call detail records (CDRs) purporting to show frequent and continuous telephonic contact between him and the co-accused around the time of the incident. The prosecution argued that these records, proved through nodal officers of the telecom service providers, demonstrated a conspiratorial nexus and justified drawing an adverse inference when the appellant offered no plausible explanation for the calls.[1]

The Court categorically rejected this contention, emphasising that Section 65-B of the Evidence Act (mirrored in Section 63 of the BSA) lays down a mandatory, special procedure for the admissibility of electronic records as secondary evidence. Referring to Anvar P.V. v. P.K. Basheer, the Court reiterated that any documentary evidence by way of an electronic record can be proved only in accordance with Section 65-B, which requires satisfaction of the conditions in sub-sections (2) and (4), including production of a certificate identifying the record, describing the manner of its production, giving particulars of the device, addressing the conditions of regular use, and being signed by a responsible official.[1]

The Court further invoked Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal, which had authoritatively held that the certificate requirement under Section 65-B(4) is a condition precedent to admissibility, and that oral evidence cannot substitute for such a certificate. In that decision, the Court had disapproved attempts to “relax” the statutory mandate and held that evidence must be led in the manner specifically prescribed, or not at all.[1]

Applying these principles, the Court found that in the present case no certificate under Section 65-B had been produced or proved in relation to the CDRs. Consequently, the records were inadmissible in evidence and could not be relied upon to support the prosecution’s case, regardless of the oral testimony of nodal officers. The Court therefore treated the CDRs as legally non-existent for the purpose of drawing any inference of guilt against the appellant.[1]

Reverse Burden Under Section 106 Evidence Act

The State had argued that the appellant’s unexplained possession of a comparatively large sum of money, despite his poor background, coupled with his alleged telephonic contact with the main accused, justified applying Section 106 of the Evidence Act (now Section 109 BSA) to shift the burden onto him to explain these incriminating circumstances. The Court, however, noted that reverse-burden provisions do not relieve the prosecution of its foundational duty to first establish primary facts through legally admissible evidence.[1]

In the specific context of the appellant, unlike the co-accused Ladu Lal whose case involved an additional layer of reverse burden, the prosecution’s case rested entirely on the three circumstantial pieces discussed above. Once the recoveries and CDRs were found to be either unreliable or inadmissible, there remained no established incriminating circumstance for Section 106 to operate upon; there can be no adverse inference for failure to explain facts the prosecution has not first proved to exist.[1]

Final Holding and Relief

Having discredited each of the three alleged incriminating circumstances, the Supreme Court held that the prosecution had “miserably failed” to establish a complete and coherent chain of circumstances pointing unerringly towards the guilt of the appellant. The Court observed that neither were the circumstances proved by cogent and admissible evidence, nor did they collectively form an unbroken chain consistent only with the appellant’s guilt.[1]

Accordingly, the Court set aside the judgments of the trial court and High Court, acquitting the appellant of all charges under Sections 302/34 and 201 IPC (and their BNS counterparts). It directed that he be released forthwith, if not required in any other case, thereby allowing the appeal in full and disposing of pending applications.[1]

Doctrinal Significance

The judgment is doctrinally significant on multiple fronts. First, it reiterates the high threshold that must be met in circumstantial evidence cases, reaffirming the Sharad Birdhichand Sarda framework and warning against convictions based on suspicion, conjecture or partially proved facts. Trial courts are reminded that every link in the chain must be individually reliable and collectively conclusive; any serious gap or infirmity must enure to the benefit of the accused.[1]

Secondly, the decision underscores that recoveries under Section 27 Evidence Act (now reflected in the BSA) do not automatically become incriminating unless the fact of recovery is itself credible and the recovered object is clearly connected to the crime. Doubts about the amount recovered, lack of proof as to its origin or role in the offence, or contradictions in documentation and testimony will substantially weaken the probative value of such recoveries.[1]

Thirdly, on forensic evidence, the Court’s insistence on a robust chain of custody aligns with global best practices and with its own recent decisions, signalling that lapses in documentation, unexplained movements of exhibits, or contradictions between oral and documentary evidence will seriously impair the evidentiary weight of FSL or DNA reports. The judgment sends a clear message that forensic reports are not self-validating; their reliability is contingent upon procedural integrity from seizure to analysis.[1]

On electronic evidence, the judgment reinforces the mandatory nature of Section 65-B, particularly in criminal trials where liberty is at stake. It discourages reliance on electronic records that have not been properly certified and warns against attempts to cure such defects through oral testimony alone, thereby strengthening due process safeguards in the digital evidence ecosystem.[1]
