Section 299 IPC vs Section 100 BNS — Culpable Homicide (Definition)

# Section 299 IPC vs Section 100 BNS — Culpable Homicide (Definition)

The definition of culpable homicide is the foundational concept upon which the entire framework of homicidal offences in Indian criminal law rests. It determines when a killing becomes a crime, and it sets the stage for the distinction between murder and culpable homicide not amounting to murder. Under the IPC, this was defined in **Section 299**. Under the BNS, the corresponding provision is **Section 100**. This page provides an educational comparison.

Section Text

Section 299 IPC (Indian Penal Code, 1860)

> "Whoever causes death by doing an act 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 he is likely by such act to cause death, commits the offence of culpable homicide."

The section also includes illustrations:

> **Illustration (a):** A lays sticks and turf over a pit, with the intention of thereby causing death, or with the knowledge that death is likely to be thereby caused. Z, believing the ground to be firm, treads on it, falls in and is killed. A has committed the offence of culpable homicide.

Section 100 BNS (Bharatiya Nyaya Sanhita, 2023)

> Section 100 BNS defines culpable homicide in substantially the same terms as Section 299 IPC — causing death by an act done with the intention of causing death, or with the intention of causing bodily injury likely to cause death, or with the knowledge that the act is likely to cause death.

Plain Language Explanation

Culpable homicide is the act of causing the death of another person with a guilty mind. It is the genus (broader category) of which murder is the species (specific category). Not every killing is culpable homicide — the killer must have either the **intention** to cause death or bodily injury likely to cause death, or the **knowledge** that the act is likely to cause death.

The three clauses of culpable homicide represent decreasing degrees of mental culpability:

1. **First clause — Intention to cause death:** The clearest form — the accused intended the death of the victim. (Example: A deliberately shoots B in the heart with the intention of killing B.)

2. **Second clause — Intention to cause bodily injury likely to cause death:** The accused intended to cause a specific bodily injury and that injury was of a nature likely to cause death. (Example: A stabs B in the abdomen, intending the stab wound, knowing that such a wound is likely to cause death.)

3. **Third clause — Knowledge that the act is likely to cause death:** The accused knew that their act was likely to cause death, even without intending death or a specific injury. (Example: A pushes a heavy object from a height into a crowded area, knowing that it is likely to kill someone.)

If the killing does not fall under any of these three clauses, it is not culpable homicide (it may be accidental death, negligent death under Section 304A IPC/106 BNS, or no offence at all).

Key Ingredients / Elements

1. **Death of a human being** — A living person must have died as a result of the accused's act.

2. **The death was caused by an act of the accused** — There must be a causal connection between the accused's act and the death.

3. **The act was done with one of the following:**

- **Intention to cause death** (Clause 1), or

- **Intention to cause bodily injury likely to cause death** (Clause 2), or

- **Knowledge that the act is likely to cause death** (Clause 3).

IPC vs BNS Comparison Table

| Feature | Section 299 IPC | Section 100 BNS |

|---|---|---|

| **Provision type** | Definition of culpable homicide | Definition of culpable homicide |

| **Three clauses** | (1) Intention to cause death, (2) Intention to cause bodily injury likely to cause death, (3) Knowledge that act is likely to cause death | Same three clauses retained |

| **Illustrations** | Provided | Provided |

| **Relationship with murder** | Section 300 IPC defines when culpable homicide becomes murder | Section 101 BNS defines when culpable homicide becomes murder |

| **Punishment** | Section 304 IPC (not Section 299 itself) | Section 105 BNS |

| **Substantive change** | — | No substantive change |

Key Differences and Observations

The BNS has **retained Section 299 IPC** in substance as Section 100 BNS. The three clauses defining culpable homicide remain identical. The illustrations are also preserved.

The relationship between culpable homicide and murder is maintained under the BNS:

- **Section 100 BNS** (= Section 299 IPC) defines culpable homicide.

- **Section 101 BNS** (= Section 300 IPC) defines when culpable homicide amounts to murder.

- **Section 105 BNS** (= Section 304 IPC) provides punishment for culpable homicide not amounting to murder.

Understanding Section 299/100 is essential because:

- If the act meets the definition of culpable homicide AND the higher threshold of murder (Section 300/101), it is murder.

- If the act meets the definition of culpable homicide but NOT the higher threshold of murder, it is culpable homicide not amounting to murder.

- If the act does not meet the definition of culpable homicide at all, but death results from negligence, it falls under Section 304A IPC / Section 106 BNS.

Important Judgments

1. **State of Andhra Pradesh v. R. Punnayya (1977) 1 SCC 467** — The Supreme Court provided a systematic framework for distinguishing between Section 299 and Section 300, holding that all murder is culpable homicide but not all culpable homicide is murder. The Court identified the "extra elements" in Section 300 that elevate culpable homicide to murder.

2. **Reg. v. Govinda (1876) ILR 1 Bom 342** — Justice Melvill's classic exposition of the distinction between culpable homicide and murder, which laid the foundation for over a century of judicial interpretation.

3. **Virsa Singh v. State of Punjab AIR 1958 SC 465** — The Supreme Court elaborated on the third clause of Section 300 (bodily injury sufficient in the ordinary course of nature to cause death) and its relationship with Section 299, providing a four-step test.

4. **Pulicherla Nagaraju v. State of Andhra Pradesh (2006) 11 SCC 444** — The Court provided practical guidance on distinguishing between Sections 299 and 300 based on factors such as the weapon used, the part of the body targeted, and the number of injuries.

5. **Thangaiya v. State of Tamil Nadu (2005) 9 SCC 650** — Discussed the third clause of Section 299 (knowledge-based culpable homicide) and its distinction from the fourth clause of Section 300.

Practical Implications

- **For legal practitioners:** The distinction between Section 299/100 and Section 300/101 is often the pivotal issue in homicide cases. The charge (murder vs. culpable homicide not amounting to murder) and the resultant punishment differ vastly. Practitioners must analyse the evidence to determine which clause applies — intention-based (first and second clause) or knowledge-based (third clause) — and whether the higher threshold of murder is met.

- **For the judiciary:** Judges must carefully analyse the mental element of the accused at the time of the act. The weapon used, the body part targeted, the number of blows, the severity of injuries, and the surrounding circumstances all inform this analysis.

- **For law students:** Understanding Section 299/100 is fundamental to criminal law. The relationship between culpable homicide (genus) and murder (species) is one of the most examined topics in law examinations and one of the most contested issues in courts.

- **For investigating agencies:** The investigation report should clearly document facts relevant to establishing the mental element — prior threats, weapon procurement, targeting of vital body parts, and post-incident conduct.

Frequently Asked Questions

Has the definition of culpable homicide changed under BNS?

No. Section 100 BNS defines culpable homicide in the same terms as Section 299 IPC. The three clauses — intention to cause death, intention to cause bodily injury likely to cause death, and knowledge that the act is likely to cause death — are retained without modification.

What is the difference between culpable homicide and murder?

Culpable homicide is the broader category that includes all intentional or knowing killings. Murder is a specific subset of culpable homicide that requires a higher degree of intention or knowledge. The additional elements that elevate culpable homicide to murder are defined in Section 300 IPC / Section 101 BNS. In simple terms, murder requires a more definite intention to kill or knowledge of certainty of death, while culpable homicide can involve a lesser degree of intention or knowledge.

Can culpable homicide exist without intention?

Yes. The third clause of Section 299/100 covers killings done with the **knowledge** that the act is likely to cause death, even without a specific intention to cause death. A person who engages in an inherently dangerous activity, knowing that it is likely to cause death, commits culpable homicide if death results — even if they did not specifically intend to kill anyone.

What if the death was purely accidental?

If the death was purely accidental — with no intention to cause death, no intention to cause bodily injury likely to cause death, and no knowledge that the act was likely to cause death — it does not meet the definition of culpable homicide. It may be a case of death by negligence (Section 304A IPC / Section 106 BNS) if there was rashness or negligence, or it may not be a criminal offence at all.
