As per case facts, Swaran Singh (appellant) and his son Harjit Singh met Tarsem Singh (PW-6), Lakhwinder Singh (PW-7), and Baljinder Singh (deceased). During an altercation, Swaran Singh stabbed Baljinder ... Singh in the stomach with a knife, leading to his death. The FIR was registered, and Swaran Singh was convicted under Section 302 IPC by the trial court. The appellant appealed, arguing that it was a single injury, without premeditation, and occurred in a sudden fight, thus seeking a conviction under Section 304 Part 1 IPC. The question arose whether the appellant's act, involving a single fatal injury during a sudden fight without premeditation, falls under Section 302 IPC or Section 304 Part 1 IPC. Finally, the High Court modified the conviction from Section 302 IPC to Section 304 Part 1 IPC, considering the single injury, lack of premeditation, and the circumstances of a sudden quarrel where the appellant did not take undue advantage or act in a cruel manner. The sentence was reduced to the period already undergone, given the appellant's advanced age and prolonged legal agony.
