Section 106 Evidence Act Cannot Substitute Proof of “Last Seen Together” in Spousal Homicides

1) Introduction

Selvi v. The Inspector of Police (2026 MHC 961) is a decision of the Madurai Bench of the Madras High Court addressing a recurring issue in circumstantial-evidence murder trials within the domestic sphere: whether, merely because the accused is the spouse and the death occurred inside the home, the court may invoke Section 106 of the Indian Evidence Act to shift the burden onto the accused to explain the death.

The appellant (A1, wife) was convicted by the Sessions Court under Section 302 IPC for allegedly killing her husband by dropping/throwing a grinding stone (MO2) on his head at about 2:00 a.m. The prosecution case was built entirely on circumstantial evidence, including alleged motive (illicit relationship), conduct after the incident, and an attempt to rely on “last seen” within the home through Section 106.

The High Court’s central legal intervention is to clarify that Section 106 is not triggered unless the prosecution first proves foundational facts—especially “last seen together”. The Court rejects any presumption that spouses are necessarily together at the relevant time merely because they are married and share a house.

2) Summary of the Judgment

• The Court held that the prosecution failed to prove the crucial foundational fact that A1 and the deceased were last seen together in the house prior to the death.
• In the absence of proof of “last seen together,” Section 106 of the Evidence Act could not be invoked to shift the burden of explanation onto A1.
• The evidence of key witnesses was weak/hostile; the remaining witnesses (notably PW4 and PW5) did not establish A1’s presence with the deceased at the material time.
• Motive and post-occurrence conduct (at best relevant under Section 8 of the Evidence Act) were insufficient to complete the chain of circumstances.
• Recovery/forensic aspects regarding MO2 were not reliable in the Court’s view (notably, the alleged wiping of blood and contradictions around the condition of MO2 versus Ex.P18).

Accordingly, the High Court concluded that the trial court’s conviction rested substantially on an impermissible application of Section 106 and was therefore unsustainable.

3) Analysis

3.1 Precedents Cited

(a) Satye Singh and Another v. State of Uttarakhand (2022 (2) SCC (Crl.) 379)

Although the judgment does not extract passages, the citation is consistent with the broader Supreme Court line that Section 106 cannot relieve the prosecution of its primary burden and that adverse inference is permissible only after the prosecution proves a coherent foundational narrative. The High Court’s approach aligns with this principle: it insists that prosecution must first establish the circumstances which call for an explanation from the accused.

(b) Anjalai v. State by the Inspector of Police, Vadalur Police Station, Cuddalore District, (2023 (3) MWN (Crl.) 582 (DB))

This Division Bench precedent was treated as directly analogous: a spousal setting where prosecution attempted to rely on Section 106. The High Court reiterated the holding that where “last seen theory” is not proved, Section 106 has no application and the court cannot draw adverse inference merely because the death occurred within a household setting.

The present judgment effectively reinforces Anjalai as a controlling template in Tamil Nadu for evaluating domestic-death cases: (i) prove “last seen,” (ii) then consider Section 106; not the reverse.

(c) Manharan Rajwade v. State of Chattisgarh (2024 SAR (Crl.) 1145)

The High Court drew a clear rule from this Supreme Court decision: absent evidence proving “last seen together,” Section 106 cannot be invoked to shift the burden to the accused spouse. By relying on Manharan Rajwade, the Court grounded its reasoning in apex authority and treated the “spouse-in-house” inference as legally inadequate unless supported by evidence.

Collective influence of the precedents: These cases converge on a single doctrinal constraint: Section 106 is a rule of limited evidentiary burden that activates only when prosecution first proves the basic facts that make the accused’s special knowledge relevant. The High Court applies that constraint to reject the trial court’s approach.

3.2 Legal Reasoning

1. Nature of proof required in circumstantial evidence cases: The Court proceeds on the standard principle that the chain of circumstances must be complete and must point unerringly to guilt, excluding reasonable hypotheses of innocence.
2. Failure of key links in the chain:
   • Motive: At best established (strained relationship/illicit relationship). The Court treats motive as supportive, not decisive.
   • “Last seen together”/foundational fact: Not proved. The Court emphasizes that even between spouses, presence together at the relevant time is a fact to be proved, not presumed.
   • Conduct after incident: Even if suspicious, it is only a relevant fact (Section 8) and cannot by itself prove murder beyond reasonable doubt.
   • Recovery/forensic link: The Court notes the problematic recovery narrative: MO2 not found at the scene, allegedly recovered 100 meters away, claim of wiped blood, yet Ex.P18 indicates blood group “B.” This undermined singular reliance on that circumstance.
   • Hostile witnesses: PW1 (father) and several others turned hostile, collapsing the prosecution’s attempt to prove additional links such as extra-judicial confession.
3. Section 106 Evidence Act—strict threshold before shifting burden: The Court restates the doctrinal limit:
   • Section 106 does not dilute the prosecution’s duty to prove guilt.
   • It applies only after the prosecution proves basic facts that place the matter within the accused’s “special knowledge.”
   • Without proof that A1 was with the deceased at the material time, it is impermissible to demand an explanation and punish silence with conviction.
4. Error identified in the trial court’s approach: The High Court explicitly finds that the trial court convicted A1 “only by resorting to Section 106,” treating spousal cohabitation as sufficient. This, the High Court holds, is a legal misapplication warranting appellate interference and acquittal.

3.3 Impact

• Domestic homicide prosecutions: Investigators and prosecutors must now anticipate heightened scrutiny on proof of presence and proximity (who was in the house, when, and how that is proved) rather than relying on marital status and the location of death.
• Limits on “Section 106 shortcut”: The judgment discourages convictions that effectively penalize an accused for failing to explain, when prosecution has not first proven that the accused was in a position requiring explanation.
• Evidence collection focus: Greater emphasis is likely on independent evidence—neighbors, call detail/location, CCTV, travel records, credible “last seen” witnesses, or scientifically consistent forensic reconstruction—before Section 106 is even argued.
• Trial court discipline in circumstantial cases: The decision reinforces that motive + suspicion + weak conduct evidence does not substitute for a complete chain; appellate courts will intervene where Section 106 is used to bridge evidentiary gaps.

4) Complex Concepts Simplified

Section 106 of the Evidence Act

A rule that when a fact is especially within the knowledge of a person, the burden of explaining that fact may fall on them. But it does not mean the accused must prove innocence. It operates only after prosecution proves basic facts showing why an explanation is uniquely expected from the accused.

“Last Seen Theory”

If the accused was the last person seen with the deceased close to the time of death, and the death is unexplained, it can become a strong circumstance. However, “last seen” must be proved by evidence; it cannot be assumed from relationship status (like husband-wife) alone.

Circumstantial Evidence & Chain of Circumstances

Where there is no direct eyewitness, the prosecution must establish a chain of proven facts that leads only to guilt and rules out reasonable alternatives. Missing links (like unproved “last seen”) break the chain.

Hostile Witness

A prosecution witness who does not support the prosecution’s version at trial. This can significantly weaken the prosecution’s ability to prove key circumstances (e.g., extra-judicial confession).

Section 8 (Evidence Act) – Conduct

A person’s conduct may be relevant (e.g., unusual behavior after an event), but it is rarely enough by itself to prove murder beyond reasonable doubt, especially when primary links are missing.

5) Conclusion

This judgment crystallizes a practical and protective rule for criminal trials based on circumstantial evidence: courts cannot invoke Section 106 of the Evidence Act to fill gaps in the prosecution case unless the prosecution first proves foundational facts, particularly that the accused and deceased were “last seen together.” Importantly, the Court rejects any assumption that spouses are inevitably together at the relevant time merely because they share a household.

The decision strengthens evidentiary discipline in domestic-death cases: suspicion, motive, and selective conduct evidence cannot replace proof. It thereby reaffirms the presumption of innocence and the prosecution’s continuing obligation to prove guilt beyond reasonable doubt before any evidentiary burden can shift in a meaningful way.
