Boby Mathew vs State Of Karnataka

The Supreme Court upheld the decisions of the trial court and High Court, confirming that the appellant's claim of insanity under Section 84 IPC was not valid as it was never pleaded during the trial. The Court emphasized that to invoke the defense of unsoundness of mind, the accused must demonstrate that they were not in a sound mental state at the time of the incident. Consequently, the appeal was dismissed, and the appellant was ordered to be taken into custody to serve the remainder of the sentence.
