Depression & Schizoid Traits Not Tantamount to Legal Insanity Under S.84 IPC if Cognitive Capacity Intact: Kerala High Court Upholds S.302 IPC Conviction - 2025-05-09

Kerala High Court Upholds Life Sentence for Nepoticide, Rules Depression Not Legal Insanity

Kochi , Kerala: The High Court of Kerala, in a significant judgment, has dismissed an appeal filed by Vijayamma , upholding her conviction and life imprisonment sentence for the murder of her 12-year-old nephew, Rahul . The Division Bench, comprising Mr. Justice Raja Vijayaraghavan V and Mr. Justice G. Girish , affirmed the trial court's decision, finding that the appellant's plea of legal insanity under Section 84 of the Indian Penal Code ( IPC ) was not substantiated, despite evidence of her suffering from depression and schizoid personality traits.

Background of the Tragic Incident

The case, S.C.No.452 of 2016, involved the appellant, Vijayamma , a nurse, who was accused of strangling her nephew, Rahul , with her pyjama string on the night of September 2, 2013, at her parental home. The child was sleeping in the same room as the appellant, which was locked from the inside. Following the act, Vijayamma herself informed the police. The Additional Sessions Judge-V, Kottayam, had found her guilty under Section 302 IPC and sentenced her to life imprisonment and a fine of Rs. 1 lakh by a judgment dated May 10, 2018.

The prosecution's narrative suggested that Vijayamma , who had a strained relationship with her sister-in-law Bindu ( Rahul 's mother), committed the act to prevent a potential reunion between Bindu and her husband Shaji ( Vijayamma 's brother and Rahul 's father). This motive was allegedly compounded by Vijayamma 's frustration over her father refusing her a loan of Rs. 15 lakhs while simultaneously offering to help Bindu build a house nearby.

Appellant's Plea of Insanity and State's Rebuttal

The appellant's counsel, Sri. Nandagopal S. Kurup, primarily argued that: * The prosecution failed to prove a motive, which is crucial in cases involving an insanity plea and a near relative as the victim. * The appellant's conduct—calling the police and not attempting to flee—indicated unsoundness of mind. * Medical records and testimonies of defence witnesses (DWs 3 to 5) suggested a history of depression and possible psychotic disorders. * The investigating agency suppressed an initial medical certificate assessing her mental condition.

Contrarily, Smt. Neema K.V., the learned Senior Public Prosecutor, argued that: * The appellant's identity as the assailant was proven. * The motive was a calculated desire to prevent her brother's reunion with his wife, driven by jealousy and feelings of betrayal. * The appellant's behaviour before and after the incident was rational. * There was no evidence that she suffered from a mental disorder impairing her ability to understand the nature or wrongfulness of her act, as required by Section 84 IPC .

High Court's Scrutiny of Evidence and Legal Principles

The High Court meticulously evaluated the evidence, confirming that Rahul 's death was a homicide by strangulation and that the appellant was responsible. The core of the appeal rested on the defence of legal insanity.

The Court extensively discussed the principles governing the plea of insanity, referencing landmark Supreme Court judgments:

* Dahyabhai Chhaganbhai Thakkar v. State of Gujarat (AIR 1964 SC 1563) : This judgment elucidates that while the prosecution must prove guilt beyond reasonable doubt, the burden to prove insanity (an exception under Section 105 of the Evidence Act) lies on the accused, albeit to the standard of a "prudent man" or preponderance of probabilities.

* Prakash Nayi v. State of Goa ((2023) 5 SCC 673) : This case reiterated that mere medical insanity is insufficient; legal insanity, where the accused is incapable of knowing the nature of the act or that it's wrong or contrary to law at the time of commission , must be established.

* Bapu Alias Gujraj Singh v. State of Rajasthan ((2007) 8 SCC 66) : The absence of motive alone cannot establish legal insanity.

The Court analyzed the medical evidence, including the testimony of PW15 (Associate Professor, Psychiatry, who evaluated the appellant post-incident) and defence witnesses (DWs 1 to 5, various doctors). PW15 had reported that the appellant "was not suffering from any psychotic disorder" at the time of evaluation and was fit for trial, though noting a history suggestive of "recurrent depressive disorder with poor treatment adherence" and "schizoid and paranoid personality traits."

The Court observed: > "An evaluation of the evidence of the medical witnesses would reveal that the appellant was not suffering from any mental ailments of such a nature that she was not in touch with the surroundings and reality. Her talk was found to be normal with no abnormal emotional changes... We are of the view that recurrent depressive disorder with poor treatment adherence, will not qualify the appellant to enable her to meet the legal threshold for insanity."

The judgment emphasized that none of the appellant's family members, including her husband and three adult children, testified to her suffering from unsoundness of mind that would impair her cognitive abilities as per Section 84 IPC . Her normal interactions on the day of the incident were also noted.

The Court's Conclusion on Insanity Plea

The High Court concluded that the evidence presented by the defence did not meet the threshold for legal insanity. The Court stated: > "We are of the opinion that the appellant though suffered from a mental ailment like depression and schizoid features even before and after the incident but from that, one cannot infer on a balance of preponderance of probabilities that the appellant at the time of the commission of the offence did not know the nature of her act; that it was either wrong or contrary to law. In our opinion, the plea of the appellant does not come within the exception contemplated under Section 84 of the Indian Penal Code."

The Court found that the trial court's finding convicting the appellant under Section 302 IPC was not liable to be interfered with.

The Verdict

Dismissing the appeal (CRL.A 797/2018), the High Court of Kerala confirmed the conviction and sentence of life imprisonment and fine imposed by the trial court. This judgment underscores the stringent requirements for successfully pleading legal insanity, distinguishing it from other forms of mental illness, and reinforces that the critical factor is the accused's cognitive capacity at the precise time of committing the offence.
