A Conviction Cannot Rest on an Unreliable Witness and a Missing Link: Supreme Court Acquits Woman Convicted of Killing Her Children

“When the Chain of Circumstantial Evidence is Broken, Every Link Fails……The conviction... is totally based on conjectures and surmises. We are of the considered view that the conviction of the appellant is not sustainable in law at all.” — Supreme Court of India

On August 6, 2025, the Supreme Court of India delivered a decisive ruling in Shail Kumari v. State of Chhattisgarh, overturning the conviction of a woman who had been sentenced to life imprisonment for allegedly drowning her two minor children. The Court, while setting aside concurrent findings by the Trial Court and the Chhattisgarh High Court, held that the prosecution failed to establish a complete and unbroken chain of circumstantial evidence — a fundamental prerequisite in such cases.

Chief Justice B.R. Gavai, writing for the Bench, stressed that the case was entirely built on a single, unreliable witness whose version was materially contradictory and legally untrustworthy.

“There must be a chain of evidence so far complete as not to leave any reasonable ground for a conclusion consistent with the innocence of the accused.” — Reaffirming the ‘Five Golden Principles’ of Circumstantial Evidence

The case involved serious charges under Section 302 IPC. The prosecution alleged that on October 11, 2003, the appellant Shail Kumari took her two children — a toddler and a 4-month-old infant — to Pujari Talab, drowned them, and then attempted to commit suicide by lying on the railway tracks. The prosecution relied almost entirely on the testimony of a local kiosk owner (PW-2), who claimed to have seen the woman walking with her children in a distressed condition, and later found the bodies floating in the pond.

However, the Court noted that this entire account rested on one solitary witness, whose testimony was not just unsubstantiated, but also riddled with improvements and omissions.

“The perusal of the cross-examination of PW-2 would reveal that he has fully improved his case in his examination-in-chief. He has narrated what does not find place in his statement under Section 161, Cr.P.C.”

The Court pointed out the complete absence of corroboration:

“Apart from the testimony of PW-2, there is nothing to connect the present appellant with the crime in question.”

The most damning observation came in relation to the prosecution’s failure to examine the one person who could have independently verified the events — the rickshaw puller allegedly sent by PW-2 to follow the woman:

“The prosecution has not even examined the Rickshaw Puller who was stated to have seen the appellant going towards the Pujari Talab and the children floating in the lake.”

“When a Witness Falls Between Wholly Reliable and Wholly Unreliable, the Court Must Seek Corroboration” — On the Use of Solitary Testimony

Referring to the classic doctrine laid down in Vadivelu Thevar v. State of Madras, AIR 1957 SC 614, the Court reiterated that witnesses fall into three categories — wholly reliable, wholly unreliable, and those requiring corroboration. PW-2, according to the Court, belonged to the third category, and the lack of corroboration made his evidence unusable.

“The Court has to separate the chaff from the grain to arrive at a conclusion... the testimony of PW-2 being unreliable, at the most, can be treated as hearsay evidence.”

In reinforcing the evidentiary standard in circumstantial cases, the Bench cited Sharad Birdhichand Sarda v. State of Maharashtra, (1984) 4 SCC 116, where the five foundational principles — now known as the “panchsheel” of circumstantial evidence — were laid down. The Court underscored:

“It is not the law that where there is any infirmity or lacuna in the prosecution case, the same could be cured or supplied by a false defence.”

“Certainly, it is a primary principle that the accused must be and not merely may be guilty before a court can convict.”

The Supreme Court observed that none of these five conditions were fulfilled in the present case, and that the High Court had erred in accepting improved testimony and conjecture in the absence of substantive evidence.

“The Law Is Clear: Suspicion, No Matter How Strong, Cannot Take the Place of Proof”

The Court was particularly critical of how the lower courts failed to apply the correct standards in assessing circumstantial evidence. While acknowledging that circumstantial evidence can form the basis of conviction, the Court held that it must be “so conclusive that it excludes every other hypothesis except the guilt of the accused.”

That threshold was not met in this case, especially when the only direct connection to the crime was a witness whose statement had been materially altered, and whose testimony lacked both internal consistency and external corroboration.

“This Court cannot allow a conviction to stand when the foundation itself is built on sand.”

In the final analysis, the Supreme Court declared:

“We are of the considered opinion that the conviction, as recorded by the Trial Court and affirmed by the High Court, is totally based on conjectures and surmises.”

The Court acquitted the appellant, noting that her detention was no longer justified. It also issued directions for her immediate release, unless required in another case.
