Shrikant Anandrao Bhosale v State of Maharashtra

Facts

The appellant, a police constable, struck his wife Surekha on the head with a grinding stone while she was washing clothes in their bathroom in the police quarters on 24 April 1994, killing her. The Sessions Court convicted him under Section 302 IPC and sentenced him to life imprisonment, and the High Court affirmed the conviction. The defence relied on medical evidence that the appellant had been suffering from paranoid schizophrenia since 1992 and was treated repeatedly in hospital around the time of the offence. There was also a family history of mental illness.

Issues

• Whether the appellant was entitled to the general exception under Section 84 IPC on the ground of unsoundness of mind at the time of the act.
• What standard of proof the accused must meet to establish the insanity defence, and whether the evidence raised a reasonable doubt as to mens rea.

Arguments

The appellant argued that he suffered from paranoid schizophrenia since 1992, was treated about 25 times in hospital between June and December 1994, and that the totality of circumstances (family psychiatric history, continuous treatment, weak motive, daylight killing with no attempt to escape) entitled him to the Section 84 exception. The State contended that the killing flowed from extreme anger following a marital quarrel that morning rather than from mental illness, and that the appellant was merely of a temperamental nature.

Held

The Supreme Court set aside the conviction and sentence and allowed the appeal, ordering the appellant to be released. It held that the burden on an accused claiming insanity is no higher than that on a party in a civil proceeding, i.e. preponderance of probabilities, and not proof beyond reasonable doubt. Even if the accused cannot conclusively establish that he was insane at the moment of the offence, evidence on record may raise a reasonable doubt as to the existence of mens rea. The Court relied on the diagnosis of paranoid schizophrenia from 1992, the numerous hospital treatments, the State's concession that he suffered from unsoundness of mind before and after the act, the family history of mental illness, the absence of any real motive, and the killing in daylight without any attempt to escape, all of which together raised a reasonable doubt about his capacity to know the nature or wrongfulness of his act.

Ratio decidendi

An accused need only establish the defence of unsoundness of mind under Section 84 IPC on a preponderance of probabilities, and the unsoundness must be judged with reference to the time of commission of the act; circumstances before and after the act, including a history of mental illness, may be considered to determine the accused's mental state at the crucial moment and to raise a reasonable doubt as to mens rea.

Significance

A landmark on the insanity defence, it settles that the accused's burden under Section 84 is only to create a reasonable doubt on the preponderance of probabilities and that courts may infer the mental state at the time of the act from medical and circumstantial evidence spanning the period before and after the offence. Under the new code the defence of unsoundness of mind continues unchanged as Section 22 BNS, 2023 (re-enacting Section 84 IPC), with murder now under Section 103 BNS and the burden of proving exceptions under Section 108 BSA, 2023 (formerly Section 105 IEA), so the principle remains good law.
