Dhrub Singh vs State of Bihar (2026 INSC 935): Supreme Court Acquits Murder Convicts, Says Guilt Can't Be Presumed From Collusion Complaint Against I.O.

Can a criminal court presume the guilt of an accused simply because a complaint of collusion was raised against the Investigating Officer? The Supreme Court answered this firmly in Dhrub Singh Etc. v. The State of Bihar (2026 INSC 935), decided on 1 September 2026, acquitting five murder convicts after finding that the prosecution's case rested on an investigation so deficient that it amounted to no investigation at all.

Background: A Broad-Daylight Murder on Election Day

The prosecution's case was that the deceased, accompanied by his son, an employee, a nephew, and a villager, was walking to his fields when the accused allegedly ambushed the group, opened indiscriminate fire, and shot the deceased in the back after an exhortation to kill everyone. The victim died of the gunshot injury. A police patrol car carrying a Magistrate, reportedly on election-day duty, arrived at the scene, causing the accused to flee. Nine prosecution witnesses were examined at trial, and six accused were convicted under Sections 302 and 307 read with Section 149 IPC, with some also convicted under Section 148 IPC and Section 27 of the Arms Act. Five of the six convicts, the first having already served his sentence and been released on remission, appealed to the Supreme Court.

Cracks in the Eyewitness Testimony

A Bench of Justice J.B. Pardiwala and Justice K. Vinod Chandran scrutinised the testimonies of the three eyewitnesses — an employee, a relative, and a son of the deceased — and found material inconsistencies about who fired the fatal shot, who exhorted the group, and the sequence of events. While the Court acknowledged that minor inconsistencies during a chaotic ambush are natural, it flagged a deeper problem: no cartridges were recovered from the scene, no weapons were seized, and none of the patrol party was examined as a witness. Blood-stained earth collected from the spot was never sent for forensic analysis, and even the bullet that killed the victim, which had exited his body, was never recovered.

The Medical Evidence Contradicted the Eyewitness Story

The postmortem examination proved decisive. The doctor's evidence indicated the victim was shot from a distance of three to four feet while in a sitting position, based on the blackening and tattooing pattern around the wound. This directly contradicted the eyewitnesses' account of the deceased walking in a line when he was ambushed and shot from behind while standing. The Supreme Court held that this expert evidence "persuades us to disbelieve the eye-witness testimony."

A Motive That Did Not Hold Up

The prosecution alleged that the accused's motive stemmed from a village dispute: a girl, said to be the sister of one accused, had allegedly been kidnapped by a boy from the deceased's village, and the deceased had refused to help trace her. The Court found no evidence establishing the kidnapping itself, no evidence linking the alleged kidnapper to the deceased, and — tellingly — the person against whom the primary motive was alleged, the father of the first accused, was never even named as an accused in the case.

"No Investigation," Not Just a Faulty One

Perhaps the most significant part of the judgment is the Court's treatment of the investigation itself. The High Court had relied on an unproven complaint of collusion against the Investigating Officer (I.O.) to justify treating the eyewitness accounts as "consistent evidence" and to brush aside the contradicting medical evidence. The Supreme Court firmly rejected this approach:

"The case is not of a faulty investigation but of no investigation having been carried out. Even the inquest was carried out before the FIS was recorded; making it pre-meditated... A faulty investigation cannot inure to the benefit of the accused, but when there is no reliable evidence, merely because the I.O was recalcitrant or a complaint of collusion was raised against him, the Court cannot presume the guilt of the accused."

The Court noted that the inquest was conducted before the First Information Statement (FIS) was even recorded — an irregularity suggesting the entire narrative may have been pre-arranged. No independent witness was examined, no clothes were seized from the deceased or the witnesses who allegedly carried the body to hospital, and there was no injury on any of the eyewitnesses despite the claim of "indiscriminate firing."

Final Verdict: Acquittal on Benefit of the Doubt

Holding that the prosecution failed to establish guilt beyond reasonable doubt, the Supreme Court acquitted all five appellants, directed their release if still in custody (subject to no other case), and cancelled their bail bonds. The appeals were allowed in full.

Why This Judgment Matters for Law Students and Lawyers

This case is essential reading for anyone preparing for criminal litigation, judiciary exams, or trial advocacy. It illustrates several core principles of Indian criminal jurisprudence: the standard of proof beyond reasonable doubt, how expert medical evidence can override eyewitness testimony, why motive alone cannot sustain a conviction, and — most importantly — that a court cannot presume guilt merely because an I.O.'s conduct is suspect. Mastering how to build and dismantle a circumstantial and testimonial case like this is a foundational skill for any criminal law practitioner.

Frequently Asked Questions (FAQs)

Can a court presume guilt because the Investigating Officer faced a collusion complaint?

No. The Supreme Court in Dhrub Singh v. State of Bihar (2026 INSC 935) held that a faulty investigation cannot inure to the benefit of the accused, but when there is no reliable evidence, a court cannot presume the guilt of the accused merely because the Investigating Officer was recalcitrant or faced a complaint of collusion.

Can expert medical evidence override eyewitness testimony in a murder trial?

Yes. In this case, the postmortem evidence showed the victim was shot from close range while seated, contradicting the eyewitnesses' account of an ambush while walking. The Supreme Court held that this contradiction was significant enough to disbelieve the eyewitness testimony.

What is the difference between a 'faulty investigation' and 'no investigation' under Indian criminal law?

The Supreme Court distinguished the two: a faulty investigation involves errors within an otherwise genuine inquiry, while 'no investigation' describes a case with no recovery of weapons or cartridges, no forensic testing of evidence, no seizure of relevant clothing, and an inquest conducted before the FIS was even recorded.

Why did the Supreme Court reject the prosecution's motive in this case?

The alleged motive centred on a village dispute over an alleged kidnapping, but the Court found no evidence proving the kidnapping occurred or linking it to the deceased. Crucially, the person against whom the primary motive was alleged was never even named as an accused in the case.

What happens when the Supreme Court acquits an accused after conviction by lower courts?

When the Supreme Court finds that guilt was not proved beyond reasonable doubt, it can set aside the conviction, acquit the accused, and order their release from custody if not required in any other case, with any bail bonds standing cancelled, as it did for the five appellants in Dhrub Singh v. State of Bihar.
