Culpable Homicide vs Murder: IPC 299, 300 and BNS 100, 101
The distinction between culpable homicide and murder is one of the central principles of Indian criminal law. Under the Bharatiya Nyaya Sanhita, 2023 (BNS), culpable homicide is defined in Section 100 and murder in Section 101. These correspond broadly to Sections 299 and 300 of the Indian Penal Code, 1860 (IPC).
The basic distinction
As explained in Rampal Singh v. State of Uttar Pradesh, culpable homicide is the genus and murder is its species. Every murder is culpable homicide, but every culpable homicide is not murder. The key issue is the degree of intention, knowledge and probability of death, together with whether a statutory exception applies.
Culpable homicide: Section 100 BNS and Section 299 IPC
A person commits culpable homicide by causing death through an act done with any one of these mental elements:
- Intention to cause death;
- Intention to cause bodily injury likely to cause death; or
- Knowledge that the act is likely to cause death.
The statutory explanations address special situations. Accelerating the death of a person already suffering from a disease or bodily infirmity may amount to causing death. The fact that proper medical treatment might have prevented death does not automatically absolve the person who caused the injury. The law also distinguishes the death of a child in the womb from that of a living child partially delivered.
Murder: Section 101 BNS and Section 300 IPC
Subject to five statutory exceptions, culpable homicide amounts to murder when one of the following applies:
- The act causing death is done with the intention of causing death.
- The offender intends bodily injury that the offender knows is likely to cause death of the particular person injured.
- The offender intends the bodily injury inflicted, and that injury is sufficient in the ordinary course of nature to cause death.
- The offender knows that the act is so imminently dangerous that it must in all probability cause death or a likely fatal injury, and acts without justification for taking that risk.
In assessing the third category, the inquiry is whether the intended injury was objectively sufficient in the ordinary course of nature to cause death; a separate intention to kill need not be proved.
Five exceptions: when culpable homicide is not murder
Exception 1: Grave and sudden provocation
A person deprived of self-control by grave and sudden provocation may fall within this exception when death is caused in the circumstances specified by law. The provocation cannot be deliberately sought as an excuse; provocation arising from lawful official acts or lawful private defence does not qualify. Whether it was sufficiently grave and sudden is a question of fact.
Exception 2: Exceeding private defence
The offender must have exercised the right of private defence in good faith, exceeded its legal limits without premeditation, and not intended more harm than necessary for that defence.
Exception 3: Public servant exceeding powers
This concerns a public servant, or someone assisting one in advancing public justice, who exceeds lawful powers while acting in good faith, believing the act lawful and necessary to perform duty, and without ill will toward the deceased.
Exception 4: Sudden fight
The death must occur without premeditation, in a sudden fight in the heat of passion upon a sudden quarrel, without undue advantage or cruel or unusual conduct. It does not matter which side started the quarrel or struck first.
Exception 5: Consent
Culpable homicide is not murder where the deceased, being above eighteen years of age, suffered death or took the risk of death with their own consent, subject to the statutory requirements. This fifth exception was incorrectly described in the earlier page as the rule about which party initiated a fight; that rule belongs to Exception 4.
Culpable homicide and murder: comparison
| Point | Culpable homicide not amounting to murder | Murder |
|---|---|---|
| Relevant law | BNS 100 and 105; IPC 299 and 304 | BNS 101 and 103; IPC 300 and 302 |
| Relationship | Wider category of unlawful causing of death | Aggravated form of culpable homicide |
| Mental element | Intention or knowledge meeting Section 100, without satisfying murder or where an exception applies | One of the four clauses of Section 101, subject to exceptions |
| Probability of death | May involve injury likely to cause death | Can involve injury sufficient in the ordinary course of nature to cause death or an act that must in all probability cause death |
| Exception | May arise where a murder exception is established | No applicable statutory exception |
Punishment under the BNS
Section 103 BNS: Murder is punishable with death or imprisonment for life and fine. Section 103(2) separately addresses murder by a group of five or more persons acting in concert on specified identity-based grounds.
Section 105 BNS: Where culpable homicide not amounting to murder involves intention to cause death or likely fatal injury, punishment may be imprisonment for life, or imprisonment for a term of not less than five years and up to ten years, together with fine. Where there is knowledge of likely death without the specified intention, punishment may extend to ten years' imprisonment and fine.
Section 106(1) BNS: Causing death by a rash or negligent act that does not amount to culpable homicide is a separate offence. It should not be confused with intentional or knowing culpable homicide. Application of Section 106(2) is subject to its separate commencement position.
Judicial interpretation
In State of Andhra Pradesh v. Rayavarapu Punnayya, the Supreme Court explained the different degrees of culpable homicide and the need to distinguish between likelihood and the higher degree of probability involved in murder. Virsa Singh v. State of Punjab remains important for understanding the clause concerning bodily injury sufficient in the ordinary course of nature to cause death. Rampal Singh v. State of Uttar Pradesh reiterates the genus-and-species distinction.
Frequently asked questions

What replaced IPC Sections 299 and 300?
For the current BNS framework, Section 100 defines culpable homicide and Section 101 defines murder.

No. All the conditions of Exception 4 must be satisfied, including absence of premeditation, undue advantage, and cruel or unusual conduct.
Can a person be convicted of murder without intending death?
Yes, depending on the proved facts, including the intention to inflict a particular injury sufficient in the ordinary course of nature to cause death.
