Culpable Homicide

Culpable homicide is the act of causing the death of a human being with the intention of causing death, or with the intention of causing such bodily injury as is likely to cause death, or with the knowledge that the act is likely to cause death. It is the genus of which murder is the most serious species. Not every culpable homicide is murder — the IPC and BNS create a careful distinction between culpable homicide that amounts to murder and culpable homicide that does not, with significantly different punishments attached to each category.

The distinction between culpable homicide and murder is one of the most examined topics in Indian criminal law — and one of the most difficult. The IPC framework, carried forward in the BNS 2023, creates a layered scheme: culpable homicide (Section 299 IPC / Section 100 BNS) as the broader category, with murder (Section 300 IPC / Section 101 BNS) as the aggravated form meeting one of four specified conditions. The difference often lies in the degree of intention or the probability of death being caused by the bodily injury intended.

The precise boundary between culpable homicide and murder turns on the four 'thirdly' conditions in Section 300 IPC (Section 101 BNS). The most frequently litigated is 'thirdly' — where the accused intended to inflict a bodily injury which was sufficient in the ordinary course of nature to cause death. The Supreme Court, in Virsa Singh v. State of Punjab, held that this condition has four sub-elements: (1) a bodily injury was caused; (2) the accused intended to cause that specific injury; (3) the injury was sufficient in the ordinary course of nature to cause death; and (4) the court must find these elements as facts, without any subjective test of what the accused thought the likely result would be.

The BNS 2023 has renumbered culpable homicide to Section 100 and murder to Section 101, with the substantive content largely preserved. A notable change is the reorganisation of the explanations and exceptions, and the consolidation of dowry death provisions that were previously in a separate section of the IPC.

For advocates, the difference between being convicted of culpable homicide not amounting to murder (maximum 10 years or life imprisonment without capital punishment) and murder (which carries death penalty in rarest of rare cases) is the most consequential single legal distinction in Indian criminal law. The defence strategy in almost every homicide case involves arguing, through medical and circumstantial evidence, that even if an unlawful killing occurred, it falls on the culpable homicide side of the Section 299/300 divide rather than the murder side.
