Conviction Set Aside for Unreliable Related-Witness Testimony, Unnatural Conduct, and FIR/Investigation Infirmities

1. Introduction

Case: Bishnupada Choudhury & Ors. v. The State of West Bengal (Calcutta High Court, Criminal Appellate Jurisdiction).
Decision date: 13-02-2026 (hearing concluded 18-12-2025).
Appeal: C.R.A. 144 of 1988 challenging conviction dated 30-03-1988 by the Additional Sessions Judge, Midnapore in Sessions Trial Case No. 13th April, 1987.

The prosecution alleged that the victim, Madhusudan Garai, was summoned to a village meeting at the Sripur “club ghar” and, during/after the meeting, was assaulted by villagers including the appellants on an accusation of an illicit affair. The first information was lodged by the victim’s wife (PW1) the next morning. The trial court convicted the appellants under Sections 147 and 304 Part-I/149 IPC and sentenced them to 5 years’ rigorous imprisonment with fine.

The core appellate issues were whether the conviction could stand when the prosecution largely depended on closely related eyewitnesses whose conduct appeared “unnatural,” whose versions were materially inconsistent (especially regarding the FIR and medical assistance), and where investigative/forensic corroboration and independent witnesses were absent.

2. Summary of the Judgment

The High Court allowed the appeal and set aside the conviction and sentence. It held that the prosecution failed to prove guilt beyond reasonable doubt due to:

  • Unreliable eyewitness account by PW1 (wife), PW3 (brother), and PW4 (sister-in-law), marked by material omissions/improvements and contradictions.
  • Unnatural conduct: despite allegedly witnessing profuse bleeding, the witnesses did not take immediate steps to secure medical help and left the victim until morning, undermining their claimed presence and credibility.
  • FIR genesis and authenticity in doubt due to mutually destructive versions by PW1 about who wrote/recorded it (the O.C. vs PW12, a political party member), when it was written, and even suggestions of more than one complaint.
  • Identity/participation uncertain: PW3 allegedly saw only appellant no.1 assaulting; PW2 stated PW1 did not disclose assailants’ names; roles of others were not specifically established.
  • Lack of independent corroboration despite alleged presence of many villagers; also deficiencies in physical/forensic support (e.g., no seizure of blood-stained earth; discrepancy about “profuse bleeding” vs no bloodstains on seized wearing apparel).
  • Improper reliance by the trial court on alleged prior statements under Section 161 CrPC without proof in accordance with Section 145 of the Evidence Act.

The appellants, already on bail, were discharged from their bail bonds and directed to comply with Section 437A CrPC (bond to secure appearance in higher court for six months).

3. Analysis

3.1 Precedents Cited

No prior judicial precedents are cited by name in the text of the judgment. The decision is instead anchored in well-settled evidentiary and criminal-law principles flowing from:

  • Section 161 CrPC (police examination statements are not substantive evidence);
  • Section 145 of the Evidence Act (mandatory method to prove contradictions);
  • General principles on interested/related witnesses, benefit of doubt, and caution where independent witnesses/forensic corroboration are available but withheld;
  • Requirements for fixing liability in group assaults implicating Sections 147 and 149 IPC, particularly the need for credible proof of participation/common object rather than omnibus allegations.

Practically, this judgment functions as a fact-intensive reaffirmation of these principles: where the “first version” (FIR) is shaky and eyewitness evidence is inconsistent and uncorroborated, the prosecution cannot bridge the gap by invoking group-liability provisions.

3.2 Legal Reasoning

(a) Credibility of related witnesses: caution is not a ritual—credibility must be earned

The Court acknowledged the orthodox rule: testimony of related/interested witnesses is not to be discarded solely due to relationship. However, it emphasized that such evidence must be consistent, probable, and confidence-inspiring. Here, the Court found multiple credibility-destroying features:

  • Unnatural conduct: PW1/PW3/PW4 claimed to see a midnight assault with bleeding from nose/ear/mouth, yet did not take immediate steps for medical aid and left the victim at the spot until morning. The Court treated this as a strong indicator that their claimed eyewitness presence was doubtful.
  • Material omissions/improvements: PW1’s court narrative introduced significant details absent from the earliest complaint—viewed as afterthought/embellishment affecting reliability.

(b) FIR as the “foundation”: contradictions about its authorship and timing undermine the prosecution’s origin story

The Court treated the FIR not merely as a formality but as the prosecution’s starting point. PW1 provided inconsistent versions: the complaint being drafted by PW12 (politically affiliated), or recorded by the O.C., and even suggestions of another complaint later. The Court found these “mutually destructive” versions sufficient to create a serious doubt about spontaneity, authenticity, and possible external influence.

(c) Identification and specific role: omnibus allegations cannot substitute proof—especially in group-liability cases

The judgment highlights a recurring problem in multi-accused prosecutions: naming many persons without delineating who did what. The Court noted:

  • PW3’s account focused on only appellant no.1 allegedly kicking the victim; presence of only “two to four persons” at the spot, creating ambiguity about a larger unlawful assembly.
  • PW2 said PW1 did not disclose names—a fact the Court treated as undermining early, confident identification.
  • PW6 saw assault by several persons he did not know, not supporting named attribution.

In effect, the Court held that criminal liability remains personal, and the prosecution must prove either specific participation or legally sustainable common object with credible evidence. Vague “they assaulted” assertions, without individual roles and without independent corroboration, were considered unsafe to uphold conviction.

(d) Investigative and forensic gaps: absence of corroboration where it should naturally exist

The Court treated investigative omissions as compounding reasonable doubt:

  • No seizure of blood-stained earth from the spot despite alleged profuse bleeding.
  • Discrepancy: witnesses claimed extensive bleeding, yet seized apparel reportedly did not show blood stains.
  • Uncertainty about the place of occurrence (I.O. first naming “Shama Sangha Club” when other witnesses did not), affecting situs certainty.
  • Failure to examine PW12 during investigation (admitted “mistake”), weakening the prosecution’s ability to present a coherent, tested narrative about FIR drafting.

(e) Correct use of Section 161 statements: trial court’s approach found legally untenable

The High Court criticized reliance on what PW6 allegedly told the Investigating Officer when PW6 did not admit to making such statement. It reiterated:

  • Section 161 CrPC statements are not substantive evidence.
  • They can be used only for contradiction following the strict method under Section 145 Evidence Act.
  • If the contradiction is not duly proved through the I.O. after drawing attention to the specific portion, it cannot be read against the accused.

3.3 Impact

  • Reinforces appellate scrutiny in older convictions: even long-standing convictions will be set aside if the evidentiary foundation is unsafe and trial court reasoning relies on inadmissible material.
  • Signals stricter expectations in group assault/Section 149 prosecutions: courts will be reluctant to uphold convictions on generalized allegations when (i) independent witnesses exist but are withheld, and (ii) specific participation/common object is not credibly proved.
  • Elevates FIR integrity as a practical safeguard: inconsistent evidence about the FIR’s author/timing, especially involving politically affiliated intermediaries, may decisively weaken the prosecution.
  • Pushes better investigation/forensic discipline: omissions like not collecting blood-stained earth, unclear seizure evidence, and not examining key persons can cumulatively create reasonable doubt even where medical evidence shows injuries.
  • Procedural compliance reminder: the direction under Section 437A CrPC underscores the post-acquittal/appeal-bond regime to ensure availability before higher courts.

4. Complex Concepts Simplified

“Interested/related witness”
A witness related to the victim (e.g., spouse/sibling) is not automatically disbelieved. But courts examine such testimony more carefully for exaggeration or bias, seeking internal consistency and (where feasible) independent corroboration.
“Material omission / improvement”
If a key fact is missing from the earliest version (like the FIR) but appears later in court testimony, it may indicate afterthought or embellishment—especially if the missing fact is central to the narrative.
“Section 161 CrPC statement”
A statement to police during investigation is not evidence by itself. It can mainly be used to contradict a witness, and only if the contradiction is proved in the legally prescribed way.
“Contradiction under Section 145 Evidence Act”
To contradict a witness using an earlier statement, the specific portion must be put to the witness and then proved (typically through the Investigating Officer). Without this, the earlier statement cannot be used to convict.
“Benefit of doubt”
If, after evaluating the evidence, a reasonable doubt remains about guilt, the accused must be acquitted. The prosecution must prove guilt beyond reasonable doubt; the defence need not prove innocence.
“Section 149 IPC (group liability)”
If an offence is committed by members of an unlawful assembly in prosecution of its common object, each member can be held liable. But the prosecution must first prove credible membership/participation and the common object; vague group allegations are insufficient.

5. Conclusion

The Calcutta High Court’s decision in Bishnupada Choudhury & Ors. v. The State of West Bengal stands for a clear, practical rule: where the prosecution’s case rests mainly on related witnesses whose conduct is improbable, whose statements materially contradict the FIR and each other, and where independent/forensic corroboration is missing alongside investigative lapses, conviction—especially under group-liability provisions—cannot be sustained.

By setting aside the conviction, the Court reaffirmed foundational criminal trial standards: FIR integrity, credible identification, lawful use of Section 161 statements, and the prosecution’s burden to exclude reasonable doubt. The judgment’s broader significance lies in its insistence that procedural and evidentiary safeguards are not technicalities—they are the mechanism through which criminal courts prevent wrongful conviction.
