Culpable homicide not amounting to murder is one of the most serious criminal offences in Singapore. It involves causing another person’s death, but in circumstances where the offence does not amount to murder.
The offence is punishable under section 304 of the Penal Code 1871, with the potential sentence depending on whether the accused intended to cause death or a likely fatal injury, or instead knew that death was likely without having that intention.
The distinction is critical. A conviction under section 304(a) can result in life imprisonment, while section 304(b) carries a maximum imprisonment term of 15 years.

What Is Culpable Homicide in Singapore?
The definition of culpable homicide is found in section 299 of the Penal Code.
Broadly, a person commits culpable homicide where they cause another person’s death by doing an act:
- with the intention of causing death;
- with the intention of causing bodily injury that is likely to cause death; or
- with the knowledge that the act is likely to cause death.
However, not every culpable homicide is murder.
The law distinguishes between murder and culpable homicide not amounting to murder according to the circumstances of the case and the accused person’s intention or knowledge.
What Does “Culpable Homicide Not Amounting to Murder” Mean?
The phrase can initially sound contradictory.
A useful way of understanding it is that culpable homicide is the broader category of unlawful killing, while murder is a more specific form of culpable homicide falling within the requirements of section 300 of the Penal Code.
This is why the accused person’s state of mind, the nature of the act, the injuries caused and the circumstances surrounding the death can become particularly important.
For a detailed explanation of the separate offence, see our guide to Murder in Singapore.
Section 304(a) vs Section 304(b): What Is the Difference?
Section 304 divides culpable homicide not amounting to murder into two categories.
The key distinction is the accused person’s intention or knowledge.
Section 304(a): Intention to Cause Death or Likely Fatal Injury
Section 304(a) applies where the act causing death was done:
- with the intention of causing death; or
- with the intention of causing bodily injury that was likely to cause death.
This is the more serious of the two categories.
Importantly, an intention to cause death is not the only way section 304(a) can apply. An intention to cause bodily injury may be sufficient where the injury intended was one that was likely to cause death.
Section 304(b): Knowledge That Death Was Likely
Section 304(b) deals with a different state of mind.
It applies where the accused acted with knowledge that the act was likely to cause death, but without an intention to cause death or to cause bodily injury likely to cause death.
In simple terms:
- Section 304(a) focuses on intention.
- Section 304(b) focuses on knowledge without that intention.
Determining which applies can make a difference to the potential sentence.
What Is the Punishment Under Section 304(a)?
Where a person is convicted under section 304(a), the Court may impose:
Life imprisonment
The offender may be sentenced to:
- imprisonment for life; and
- may also be liable to caning.
Imprisonment of up to 20 years
Alternatively, the offender may be sentenced to:
- imprisonment for a term of up to 20 years; and
- may also be liable to a fine or caning.
Section 304(a) therefore carries serious sentences.
What Is the Punishment Under Section 304(b)?
Where the offence falls under section 304(b), the punishment is:
- imprisonment for up to 15 years;
- a fine;
- caning; or
- any combination of those punishments.
The maximum imprisonment term is lower than under section 304(a), reflecting the important distinction between intending the fatal outcome or likely fatal injury and knowing that death was likely without having that intention.
How Does the Court Determine Intention or Knowledge?
In many culpable homicide cases, there may be no direct statement from an accused person saying what they intended.
The accused person’s state of mind may therefore have to be determined from the surrounding evidence.
Depending on the case, relevant matters may include:
- the nature of the act;
- the weapon or object used;
- the number and location of injuries;
- the degree of force used;
- what happened immediately before the incident;
- statements or threats allegedly made;
- messages or other communications;
- CCTV or video evidence;
- medical and forensic evidence; and
- the accused person’s actions before and after the death.
The court considers the evidence as a whole when determining what the accused intended or knew.
What Is the Difference Between Culpable Homicide and Murder?
Both offences involve causing another person’s death, but they should not be treated as interchangeable.
Murder is defined under section 300, while culpable homicide is defined under section 299 and punishment for culpable homicide not amounting to murder is provided under section 304.
The legal distinction can depend on the accused person’s state of mind, the nature of the injury or act, and whether the circumstances satisfy the requirements for murder.
The distinction is important because a murder conviction can carry the death penalty, whereas section 304 provides different sentencing ranges for culpable homicide not amounting to murder.
If a murder charge is being considered or has already been brought, the precise legal classification of the alleged killing can therefore have profound consequences.
Is Culpable Homicide the Same as Manslaughter?
People sometimes use the word “manslaughter” when describing a death that does not amount to murder.
However, Singapore’s Penal Code uses the statutory term “culpable homicide not amounting to murder”.
When discussing a Singapore criminal charge, it is therefore more accurate to refer to the particular offence under the Penal Code rather than simply calling it manslaughter.
Is Section 304 the Same as Section 304A?
No. This is an important distinction.
Section 304 concerns culpable homicide not amounting to murder and involves the necessary intention or knowledge.
Section 304A is a separate offence concerning causing death by a rash or negligent act that does not amount to culpable homicide.
Under section 304A:
• causing death by a rash act can result in imprisonment for up to 5 years, a fine, or both; and
• causing death by a negligent act can result in imprisonment for up to 2 years, a fine, or both.
The difference between section 304 and section 304A therefore goes directly to the accused person’s state of mind and the nature of the conduct involved.
Can a Murder Charge Become Culpable Homicide Not Amounting to Murder?
Depending on the circumstances and evidence, the legal classification of a killing can be a significant issue in criminal proceedings.
A central question may be whether the evidence establishes the requirements of murder under section 300, or whether the circumstances instead support culpable homicide not amounting to murder.
This requires careful consideration of matters including:
• intention;
• knowledge;
• the nature of the injuries;
• medical evidence;
• how the death occurred;
• the circumstances surrounding the incident; and
• any applicable defence or exception under the law.
It should not be assumed that every intentional act causing death automatically results in the same criminal charge.
What Defences May Apply to a Culpable Homicide Charge?
The defence available will depend entirely on the circumstances.
Issues that may need to be considered include whether the prosecution can establish:
The required intention or knowledge
A key issue may be whether the accused actually possessed the state of mind required for the offence alleged.
Causation
The Prosecution must establish the necessary connection between the accused person’s conduct and the death.
This can involve medical and forensic evidence, particularly where there were pre-existing injuries, medical conditions or intervening events.
The circumstances surrounding the incident
Depending on the case, the defence may also need to examine whether any general defence or relevant exception under the Penal Code applies.
Because homicide cases are highly fact-specific, the appropriate defence cannot usually be determined simply from the fact that a death occurred.
What Should I Do If I Am Investigated for Culpable Homicide?
A culpable homicide investigation should be treated seriously from the beginning.
Police statements, CCTV footage, mobile phone records, messages, forensic evidence, medical reports and witness statements may all become important.
If you are under investigation, you should understand the allegation against you and obtain legal advice about your position.
If you have already been charged, a criminal defence lawyer can examine the precise charge — including whether it is brought under section 304(a) or section 304(b) — review the available evidence and advise you about your options.

Frequently Asked Questions About Culpable Homicide in Singapore
It depends on whether the offence falls under section 304(a) or section 304(b).
Under section 304(a), an offender may face life imprisonment, or imprisonment for up to 20 years, together with the applicable additional punishment.
Under section 304(b), imprisonment may extend to 15 years, and the offender may also face a fine, caning, or a combination of those punishments.
The principal distinction concerns the accused person’s state of mind.
Section 304(a) applies where there was an intention to cause death or bodily injury likely to cause death.
Section 304(b) applies where there was knowledge that death was likely, but without the intention required under section 304(a).
No.
Although both involve causing death, murder is governed by section 300, while culpable homicide is defined under section 299 and culpable homicide not amounting to murder is punished under section 304.
The legal requirements and potential punishments are different.
Section 304 requires the relevant intention or knowledge associated with culpable homicide.
Causing death by a rash or negligent act that does not amount to culpable homicide is separately dealt with under section 304A.
The distinction can have a major effect on the potential sentence.
You do not need to wait until a criminal charge has been filed before seeking legal advice.
Where police are investigating a death, statements and other evidence gathered during the investigation may become important later. Obtaining advice early can help you understand the investigation process, the allegation and your legal position.
