Allahabad HC Overturns Life Sentence for Mother Accused of Poisoning Three Children

The Allahabad High Court has overturned a life sentence awarded to a mother for the alleged poisoning of her three children, ruling that the prosecution's failure to establish a continuous chain of circumstantial evidence cannot be salvaged by shifting the burden of proof onto the accused. The Bench emphasized that Section 106 of the Indian Evidence Act, 1872 does not absolve the state of its primary duty to prove guilt beyond reasonable doubt, even in cases of unnatural deaths occurring within the privacy of a home.

Justice Manoj Bajaj and Justice Harvir Singh, while hearing an appeal against a 2015 conviction, observed significant gaps in the police investigation and forensic evidence. The Bench noted that the prosecution failed to prove the exclusive possession of the premises or the actual administration of poison through recovered food items.

Key Takeaways

Prosecution's Initial Onus

Section 106 of the Evidence Act cannot be used to bridge gaps in the prosecution's case if they fail to establish a prima facie link between the accused and the crime.

Circumstantial Evidence Chain

In cases relying solely on circumstances, the evidence must not only be consistent with the guilt of the accused but also entirely inconsistent with their innocence.

Forensic Discrepancies Fatal

Contradictions between post-mortem findings (empty stomachs) and forensic reports (poisoned food) create reasonable doubt that must benefit the accused.

Motive Requires Evidence

Allegations of bad character or illicit relations as a motive for murder must be backed by admissible evidence rather than bald statements from estranged family members.

Forensic Lapses and Evidentiary Contradictions

The Allahabad High Court scrutinized the recovery of food items alleged to have contained aluminum phosphide. It found a six-day delay in sending samples for scientific analysis and noted a critical contradiction: while the FSL report detected poison in 'roti and sabzi', the post-mortem reports of the deceased children indicated their stomachs were empty or contained only white liquid. The Bench observed that the prosecution failed to prove the source of the recovered food or that it was ever administered to the children.

The Allahabad High Court accordingly allowed the appeal while setting aside the conviction and sentence, acquitting the mother of all the charges.

Application of Section 106 of the Evidence Act

The Allahabad High Court discussed the statutory interpretation that "Section 106 Indian Evidence Act, 1872 cannot be invoked to make up the inability of the prosecution to produce evidence of circumstances pointing to the guilt of the accused. This section cannot be used to support a conviction unless the prosecution has discharged the onus by proving all the elements necessary to establish the offence. It does not absolve the prosecution from the duty of proving that a crime was committed even though it is a matter specifically within the knowledge of the accused and it does not throw the burden on the accused to show that no crime was committed."

Ratio

In criminal trials based on circumstantial evidence, the prosecution must discharge the initial burden of proving facts that lead to a reasonable inference of guilt before the onus shifts to the accused under Section 106 of the Indian Evidence Act, 1872. Presumption of fact under Section 114 is a process of reasoning that requires the existence of proved facts; it cannot replace the requirement of proving guilt beyond reasonable doubt.

Background

The appellant was convicted under Sections 302 and 328 of the I.P.C. following the death of her three minor sons in 2012. The prosecution alleged that the appellant, who had been living separately from her husband for five years, poisoned her children as they were an obstacle to her remarriage. The trial court relied on the testimony of a purported friend of the appellant and the fact that the deaths occurred in the house where she resided.

However, the High Court found that the house was shared with other family members, and the prosecution failed to produce the appellant's brother, the primary informant, during the trial. Citing precedents like Tulsiram Sahadu Suryawanshi and Anr. vs. State of Maharashtra ( "(2012) 10 SCC 373": 2012 CaseBase(SC) 352) and Anees vs. The State Govt. of NCT ( "2024 INSC 368": 2024 CaseBase(SC) 42), the Allahabad High Court held that the prosecution had left "loose ends" and failed to complete the chain of events. Consequently, the conviction was set aside due to lack of cogent and credible evidence.
