Police Fabrication & Suo-Motu FIR Duty: The Supreme Court’s Landmark Ruling in K.P. Tamilmaran v. The State (2025 INSC 576)

1. Introduction

The Supreme Court of India, in K.P. Tamilmaran v. The State, confronted a disturbing case of “honour-killing” in Tamil Nadu where two Dalits—Murugesan and his wife Kannagi—were poisoned in public view for daring to marry across caste lines. Fifteen persons, including two police officers, were arraigned; thirteen were convicted by the Trial Court, and sentences were partly altered by the Madras High Court. Eleven of those convicts sought relief before the Supreme Court. The central legal issues were:

1. Whether the prosecution evidence—riddled with hostile witnesses—was sufficient to sustain convictions for murder and conspiracy.
2. The scope of a court’s power to rely on portions of “hostile” testimony and to summon additional witnesses under s.311 CrPC.
3. Whether the investigating police officers (A-14 & A-15) could be punished under ss.217-218 IPC and, crucially, under ss.3(2)(i) & 4 of the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989 for (i) non-registration of the FIR, and (ii) fabricating evidence that falsely implicated Dalit relatives of the deceased.
4. Quantum of sentence, including the commutation of a death sentence (A-2) and award of victim compensation.

2. Summary of the Judgment

• All eleven appeals were dismissed; High Court convictions and sentences were affirmed.
• A-14 (Sub-Inspector): Conviction under s.217 IPC & s.4 SC/ST Act upheld; acquittal under s.218 IPC & s.3(2)(i) SC/ST Act left undisturbed.
• A-15 (Inspector): Conviction under ss.217, 218 IPC and ss.4, 3(2)(i) SC/ST Act upheld; life-imprisonment maintained.
• A-2 (brother of Kannagi): Death penalty already commuted by High Court to life imprisonment—unchallenged affirmation.
• The Court clarified the evidentiary value of hostile witnesses, endorsed liberal use of s.311 CrPC & s.165 Evidence Act, and reiterated the Lalita Kumari obligation of police to suo-motu register FIRs on receipt of information of cognisable offences.
• State of Tamil Nadu directed to pay ₹5 lakh compensation to the parents of Murugesan in addition to earlier awards.

3. Detailed Analysis

3.1 Precedents Cited & Their Influence

3.2 Court’s Legal Reasoning

1. Credibility of Evidence despite Hostility
   The Court marshalled key testimonies (PW-1, 2, 3, 15 & the eye-witness PW-49) and explained that hostile portions may be severed, relying on the unshaken core that established:
   • Prior threats by A-2.
   • Torture of Murugesan in public view.
   • Poisoning by A-2.
   • Complicity of remaining Vanniyar accused.
2. Role of PW-49 & Section 311 CrPC
   The prosecution rightly invoked s.311 to summon the step-mother who had not been cited. The Court clarified the difference between prosecution witnesses and “court witnesses” and emphasised that judges may & must actively seek truth under s.165 Evidence Act.
3. Liability of Police Officers
   • Non-registration of FIR: Violation of ss.154 & 157 CrPC and duty under s.4 SC/ST Act.
   • Fabrication of Evidence: Inspector A-15 authored a false extra-judicial confession and framed Dalits, attracting s.218 IPC and the aggravated offence under s.3(2)(i) SC/ST Act—punishable with life imprisonment.
   • Sub-Inspector A-14 was spared s.218 & s.3(2)(i) liability because fabrication could not be directly attributed to him, but remained culpable for deliberate inaction.
4. Sentence & Compensation
   Death penalty of A-2 already commuted. Compensation awarded in consonance with victims’ rights jurisprudence (Art. 21 & Victim Compensation Schemes).

3.3 Impact of the Decision

• Police Accountability: First SC pronouncement sentencing a police officer to life under s.3(2)(i) SC/ST Act for fabricating evidence to shield caste perpetrators. It sends a stern warning that dereliction or sabotage of investigations involving marginalised communities will invite severe penal consequences.
• Honour-Killing Prosecutions: Reaffirms that caste-based murders qualify for aggravated treatment; upholds rigorous sentences even two decades after the crime, underscoring that delay will not dilute culpability.
• Evidentiary Flexibility: Clarifies once again that partial reliance on hostile witnesses is legally sound; trial courts may confidently salvage truthful portions.
• Judicial Pro-Activeness: Strong endorsement of a judge’s inquisitorial powers (s.165 Evidence Act) and the mandatory facet of s.311 CrPC.
• Victimology: Supplements state victims’ scheme with additional compensation, reinforcing constitutional empathy toward victims’ families.

4. Complex Concepts Simplified

“Hostile” Witness

Not defined in the Evidence Act. It is a witness who deviates from earlier statements. Court may permit his cross-examination by the calling party under s.154 Evidence Act, yet his entire testimony is not automatically discarded; credible parts can be used.

Section 311 CrPC

Empowers the court, at any stage, to summon or recall any person whose evidence appears essential. First part (“may”) is discretionary; second part (“shall”) is mandatory when justice demands.

Section 165 Evidence Act

Gives the judge a unique right to ask any question, in any form, at any time, to uncover truth—transcending normal adversarial limits.

Sections 217 & 218 IPC

Target misconduct by public servants: knowingly disobeying law to save offenders (s.217) or fabricating records (s.218). Punishable up to 2 & 3 years respectively.

Sections 3(2)(i) & 4 SC/ST Act

3(2)(i) punishes non-SC/ST persons who fabricate false evidence causing a member of SC/ST to be tried for a capital offence—life imprisonment (or death if execution results). Section 4 punishes public servants for wilful neglect of duties under the Act—6 months to 1 year.

Suo-Motu FIR Duty

Lalita Kumari principle: police must register FIR once they receive any information from any source about a cognisable offence; they cannot wait for a formal complaint.

5. Conclusion & Key Takeaways

1. The Supreme Court has cemented the doctrine that police officers who fabricate or suppress evidence in caste atrocities will face the full rigour of both IPC and SC/ST Act, including life imprisonment.
2. Non-registration of an FIR, especially in sensitive caste-based crimes, is itself a grave offence attracting s.4 SC/ST Act.
3. Hostile or related witnesses are not to be lightly discarded; courts must sieve truth from falsehood, utilising s.311 CrPC and s.165 Evidence Act.
4. Judicial pro-activeness in summoning additional witnesses manifests the “voyage of discovery in search of truth” touted in Ram Chander.
5. The decision underscores systemic caste prejudice within law-enforcement and sets a transformative precedent for accountability & victim justice.
