Facts of the Case
-
The incident occurred on 27th September 2018, when the appellant allegedly attacked and killed a man named Asam Gota using an iron pipe.
-
The incident was witnessed by Fagu Ram Karanga, who fled the scene when attacked.
-
The appellant was arrested and charged under Sections 302, 352, and 201 of IPC.
-
The Trial Court convicted him and sentenced him to life imprisonment, which was later upheld by the High Court.
-
The appellant claimed that he was of unsound mind at the time of the offence.
-
However, the High Court rejected this defence, relying on a medical report from December 2023 which declared him mentally sound.
-
In the Supreme Court, defence counsel cited prosecution witnesses’ testimonies indicating prior mental instability and referred to key judgments on the standard of proof under Section 84 IPC.
Issues
-
Whether the appellant was legally insane at the time of committing the offence.
-
Whether prosecution witnesses' depositions created a reasonable doubt about the accused’s mental condition.
-
Whether failure to conduct a timely medical examination prejudiced the appellant’s right to fair trial.
-
Whether a five-year-later medical assessment could be relied upon to judge the appellant’s condition at the time of the crime.
Judgement
-
The Supreme Court ruled that the testimonies of prosecution witnesses clearly indicated long-standing mental illness.
-
It emphasized that the accused need not conclusively prove insanity; rather, it is enough to create reasonable doubt about sanity.
-
The 2023 medical report was held irrelevant for evaluating the mental condition during the 2018 incident.
-
The appeal was allowed, and the conviction and sentence were set aside.
Held
-
A lunatic is not criminally liable as per law since he cannot comprehend or defend against charges.
-
The right to a fair defence is part of Article 21 of the Constitution.
-
Standard of proof for insanity under Section 84 IPC is reasonable doubt, not conclusive proof.
-
Failure of prosecution to request a medical examination despite witness testimony was a major procedural lapse.
-
The accused is entitled to benefit of doubt and was acquitted.
Analysis
-
The Court emphasized that the right to defend oneself is a fundamental right under Article 21, and a lunatic cannot exercise this right meaningfully.
-
It relied on precedents such as Dahyabhai Chhaganbhai Thakkar v. State of Gujarat, which held that the standard of proof for insanity is a mere reasonable doubt.
-
The Court criticized the lack of timely medical examination despite testimonies about the appellant’s mental instability.
-
It reiterated that legal insanity must be established based on conduct before, during, and after the offence, not just medical records.
-
It held that failure to consider witness testimony and procedural gaps like not re-examining key witnesses prejudiced the trial.
