which was lying there, though the single injury inflicted on the vital part of the body by which he (deceased) died. Considering the nature of injury which has occurred on the body of the deceased and further considering the postmortem report (Ex.P/12) proved by Dr. Shrey Chandrakar (PW-4), only single injury has occurred over the body of the deceased, it is apparent that appellant must have had knowledge that such injury inflicted by him on the body of the deceased would likely to cause his death, as such, this is a case which would fall within the purview of Exception 4 to Section 300 of IPC, as the act of the appellant herein completely satisfies the four necessary ingredients of Exception 4 to Section 300 IPC i.e. (i) there must be a sudden fight; (ii) there was no premeditation; (iii) the act was committed in a heat of passion and (iv) the appellant had not taken any undue advantage or acted in a cruel or unusual manner and, therefore, the conviction of the appellant under Section 302 of the IPC can be altered/converted to Section 304 Part-II of the IPC.
