What is IPC Section 304?
IPC Section 304 prescribes the punishment for culpable homicide not amounting to murder, which is itself defined by Section 299 IPC and distinguished from murder (Section 300) by both the degree of intention or knowledge involved and by the five statutory exceptions that take an otherwise murderous act out of the scope of Section 300 — grave and sudden provocation, exceeding the right of private defence in good faith, a public servant exceeding their lawful powers, a sudden fight without premeditation, and death caused with the consent of a person above 18.
Section 304 sits within Chapter XVI of the IPC ("Of Offences Affecting the Human Body"). Indian courts have long recognised culpable homicide as the "genus" and murder as its most serious "species" — meaning every murder is a culpable homicide, but not every culpable homicide rises to the level of murder. Distinguishing between the two, and between the two parts of Section 304 itself, is one of the most extensively litigated areas of Indian criminal law.
Important Update: IPC to BNS Transition
With effect from 1 July 2024, the Indian Penal Code has been replaced by the Bharatiya Nyaya Sanhita (BNS), 2023 for offences committed on or after that date. Section 304 IPC now corresponds to Section 105 of the BNS. Notably, the BNS has introduced a statutory minimum sentence of 5 years' imprisonment for the Part I category (intention to cause death or such bodily injury as is likely to cause death) — a minimum that did not exist under the original IPC provision, where the court had complete sentencing discretion up to the maximum. FIRs registered before 1 July 2024 continue to be tried under IPC 304; incidents after that date are registered under the corresponding BNS provision.
Legal Provision — Text of Section 304 IPC
This provision must be read together with Section 299 IPC, which defines "culpable homicide," and Section 300 IPC, which defines "murder" and its five exceptions. The first limb of Section 304 (commonly called "Part I") applies where the act was done with intention; the second limb ("Part II") applies where the act was done only with knowledge, without any accompanying intention to cause death or a fatal injury.
Punishment Under Section 304 — Part I and Part II
| Part I (Intention) | Imprisonment for life, or imprisonment of either description up to 10 years, and fine — applies where the act was done with the intention of causing death, or of causing such bodily injury as is likely to cause death |
|---|---|
| Part II (Knowledge Only) | Imprisonment of either description up to 10 years, or fine, or both — applies where the act was done with the knowledge that it was likely to cause death, but without any intention to cause death or such bodily injury |
| Nature of Offence | Cognizable — police can register an FIR and investigate/arrest without prior court order |
| Bailable / Non-Bailable | Non-bailable — bail is not a matter of right and must be applied for before the court |
| Compoundable | Not compoundable |
| Triable By | Court of Session |
| Limitation Period | None — being punishable with more than 3 years' imprisonment, there is no limitation period under Section 468 CrPC |
The distinction between Part I and Part II is not a mere technicality — it can be the difference between a life sentence and a much shorter term. Courts examine factors such as the weapon used, the nature and location of the injury, the number of blows, and the surrounding circumstances (a sudden quarrel versus a targeted, forceful attack) to determine which part applies on the facts of a given case.
Key Ingredients / Essential Elements
For a conviction under Section 304, the prosecution must establish the following, in the sequence courts typically follow:
Death was caused by the accused's act
A causal connection between the accused's conduct and the victim's death must first be established.
The act amounts to "culpable homicide" under Section 299
The act must have been done with the intention of causing death, with the intention of causing bodily injury likely to cause death, or with the knowledge that it was likely to cause death.
The act does not meet the higher threshold for "murder" under Section 300
Either the accused's intention/knowledge does not satisfy any of the four clauses of Section 300, or the case falls within one of the five statutory exceptions to murder.
Classification into Part I or Part II
If there was an intention to cause death or a fatal injury, Part I applies. If there was only knowledge that death was likely, without any such intention, Part II applies.
Absence of a complete legal defence
The act must not fall within a complete general exception (such as genuine, proportionate self-defence, or accident) that would remove criminal liability altogether.
What Should You Do — For the Victim's Family and For the Accused
Section 304 cases frequently arise from sudden fights, domestic altercations, or provoked confrontations, rather than planned attacks — which is precisely why the classification between murder and culpable homicide, and between Part I and Part II, is so heavily contested. What you should do depends on which side you're on.
If You Have Lost a Family Member
- Ensure a post-mortem examination is conducted promptly and request a copy of the report, as it is central to establishing the cause of death and the nature of injuries.
- Preserve any evidence of what led to the incident — messages, witness accounts, CCTV footage, or a history of prior threats or disputes.
- File a written complaint at the local police station; since the offence is cognizable, police are required to register an FIR.
- Ensure the FIR accurately captures the sequence of events, since this affects whether the case proceeds as murder (Section 302) or culpable homicide (Section 304).
- Engage a lawyer to represent the family's interests during the trial, including at the bail stage, given how heavily contested classification issues can be.
- Consider pursuing victim compensation under applicable schemes, independent of the outcome of the criminal trial.
If an FIR / Complaint Is Filed Against You
- Do not ignore a police notice or summons — non-appearance can lead to a non-bailable warrant.
- Do not make statements to the police without a lawyer present; anything you say can be used as evidence.
- Engage a criminal lawyer immediately, given the seriousness of the offence and its overlap with murder charges.
- Gather evidence bearing on the actual circumstances — provocation, self-defence, absence of premeditation, or a sudden fight without prior intent — since these can determine whether the charge is reduced from murder to Section 304, or from Part I to Part II.
- Bail is not automatic and is typically contested before the Sessions Court or High Court, which examines the nature of the injury, the weapon used, and the surrounding circumstances closely.
- Work closely with your lawyer on medical and forensic evidence, since this often determines the final classification and sentence.
Murder vs Culpable Homicide, and Part I vs Part II — The Most Important Distinctions
Courts have described the boundary between murder and culpable homicide as one that has "vexed" them for over a century, since both ultimately involve a death. The Supreme Court has emphasised a structured approach: first establishing that the accused's act caused death, then examining whether it meets the definition of culpable homicide under Section 299, and only then assessing whether it crosses into murder under Section 300, or is pulled back into Section 304 by one of the five exceptions. Within Section 304 itself, Part I (intention) is reserved for cases with a genuine intent to kill or cause fatal injury, while Part II (knowledge only) applies to cases — often sudden fights or single, unplanned blows — where death was foreseeable but not intended.
FIR Filing & Bail Process Under Section 304
Filing the Complaint / FIR
Since Section 304 (and its parent offence structure) is cognizable, the police are legally bound to register an FIR — often initially under Section 302 (murder), with the classification reassessed as the investigation and evidence develop.
Investigation
The Investigating Officer arranges the post-mortem, collects forensic and medical evidence, records witness statements, and examines the weapon and circumstances to assess the appropriate charge.
Bail Application
Being non-bailable and generally as serious as murder in its early stages, bail applications are typically heard before the Sessions Court or High Court, which weighs the medical evidence, custody period, and risk of tampering closely.
Chargesheet, Committal & Trial
The chargesheet is filed before the Magistrate, who commits the case to the Court of Session given its exclusive jurisdiction. Charges are framed — potentially under Section 302, with Section 304 as an alternative — and the trial proceeds.
Verdict & Classification
On conviction, the court determines not just guilt but the precise classification — murder, or culpable homicide under Part I or Part II — based on the totality of evidence, which directly determines the sentence imposed.
Important / Landmark Cases on Section 304
The following judgments are frequently relied upon by both prosecution and defence lawyers in Section 304 matters. This is general legal information for awareness — always have a lawyer verify how a precedent applies to your specific facts.
State of Andhra Pradesh v. Rayavarapu Punnayya & Anr., (1976) 4 SCC 382
The Supreme Court gave one of the most authoritative expositions on the distinction between murder and culpable homicide, describing culpable homicide as the "genus" and murder as its most aggravated "species" within that genus.
K.M. Nanavati v. State of Maharashtra, 1962 Supp (1) SCR 567
In this famous case, a naval officer who shot and killed his wife's lover claimed the defence of grave and sudden provocation. The Supreme Court ultimately rejected the plea of provocation on the facts and upheld a murder conviction, providing an influential analysis of when this exception to Section 300 can genuinely apply.
Virsa Singh v. State of Punjab, AIR 1958 SC 465
The Supreme Court laid down the foundational test for Section 300 "thirdly" — that where a bodily injury is found to be present, the intention to cause that particular injury must be proved, and it must then be objectively shown that the injury was sufficient in the ordinary course of nature to cause death.
Santhanam v. State of Tamil Nadu, 2009 INSC 607
The Supreme Court modified a murder conviction to Section 304 Part I, sentencing the appellant to 10 years, after concluding on the facts that the case did not meet the higher threshold required for murder under Section 300.
Pulicherla Nagaraju alias Nagaraja Reddy v. State of Andhra Pradesh, (2006) 11 SCC 444
The Supreme Court laid down a set of factors relevant to determining intention in homicide cases — including the weapon used, the number and nature of injuries, the part of the body targeted, the presence or absence of premeditation, and the circumstances preceding and during the incident.
