As per case facts, on 09.05.2021, the appellant, Laxman Doraiburu, and his elder brother, Ankura Doraiburu, were returning from a marriage ceremony when they began quarreling over the sale of ... their Ox. The appellant then stabbed his brother from behind with a knife, causing fatal injuries. The deceased's wife lodged the FIR. The trial court convicted the appellant for murder under Section 302 IPC, leading to this appeal where the appellant contended the act fell under Exception-4 of Section 300 IPC. The question arose whether the appellant's act, a single stab in a sudden quarrel without premeditation, should be classified as culpable homicide not amounting to murder under Exception-4 of Section 300 IPC, considering there was no apparent intention to kill or undue advantage. Finally, the court determined that the act was committed in a sudden quarrel without premeditation, without intent to kill or taking undue advantage, thus satisfying the conditions of Exception-4. The conviction was altered from Section 302 IPC to Section 304-Part-1 IPC, and the appellant was sentenced to seven years rigorous imprisonment and a fine.
