Motive Loses Significance Where Direct Ocular Evidence Is Reliable: Gauhati High Court Upholds Murder Conviction

"The non-recovery of the murder weapon does not materially affect the case of the prosecution, where there is unimpeachable oral evidence corroborated by medical evidence." Gauhati High Court, in a ruling dated August 25, 2026, upheld the conviction of a woman for the murder of a youth, ruling that when direct, credible eyewitness testimony is available, the absence of a stated motive or the failure to recover a weapon is not fatal to the prosecution's case.

A division bench comprising Justice Michael Zothankhumia and Justice Shamima Jahan observed that the accused’s plea of private defence was not plausible, as the evidence established her presence and the commission of the act beyond reasonable doubt.

The appellant, Sarala Mandal, had challenged her conviction under Section 302 of the IPC, awarded by the Sessions Judge, Baksa, for the murder of one Ratan Barman in June 2022. The prosecution alleged that the appellant had stabbed the deceased in the neck with a knife on a public road. While the appellant pleaded self-defence, claiming the deceased attempted to rape her, the trial court rejected this explanation and sentenced her to life imprisonment.

The primary questions before the court were whether the evidence of a sole eyewitness was sufficient to sustain a conviction, whether the plea of private defence had been established by a preponderance of probabilities, and what significance the alleged non-recovery of the weapon and lack of motive held in the overall case.

Reliability of the Sole Eyewitness

The court analyzed the testimony of the sole eyewitness, PW-3, who was accompanying the deceased at the time of the incident. Despite the defence’s attempt to paint the witness as unreliable, the court found her testimony "fully trustworthy and absolutely free from any kind of blemish." The bench reaffirmed the settled legal position that a conviction can be based on the testimony of a single eyewitness, provided the witness passes the test of reliability, as held in Anil Phukan vs. State of Assam.

Court Rejects Plea of Self-Defence

Regarding the appellant’s contention of self-defence, the court noted that while an accused is not required to prove their defence beyond reasonable doubt but only by a preponderance of probabilities, the explanation offered in this instance failed the test of plausibility. The court highlighted that the incident occurred on a road in the evening, making the alleged attempt of rape highly improbable.

"The explanation given by the appellant... does not appear to be plausible, as darkness had not yet fallen on the road leading to the market," the court observed.

Non-Recovery of Weapon Not Fatal

The defence had argued that the prosecution's case was vitiated by the non-recovery of the weapon and discrepancies in the FIR. Citing the Supreme Court's decision in Ghanshyam Mandal and Ors. Vs. The State of Bihar, the bench reiterated that the non-recovery of a weapon is not a ground for acquittal when there is consistent medical and ocular evidence. The post-mortem report confirmed that the cause of death was shock and haemorrhage from an incised stab wound to the neck, which corroborated the eyewitness account.

Motive Becomes Secondary

The bench further addressed the issue of motive, noting that while motive is a significant factor in cases resting on circumstantial evidence, it loses its importance when there is clear, cogent, and reliable ocular testimony. The court observed that because the prosecution established the identity of the assailant and the nature of the fatal injury through direct evidence, the absence of a clear motive did not assist the appellant.

"FIR is not an encyclopedia of facts; it is only the information which gives rise to an investigation and on the basis of which facts pertaining to an alleged crime is initiated."

The court ultimately concluded that the prosecution had proved the guilt of the appellant beyond reasonable doubt. Despite minor contradictions in the testimony of certain witnesses regarding the shouting of the eyewitness, the presence of the eyewitness and the commission of the crime were proven by corroborated evidence. Finding no merit in the appeal, the division bench dismissed the challenge and upheld the trial court’s conviction.
