Section 299 of the IPC defines culpable homicide and the essentials of the same are:
- Causing the death of a human being.
- Death must have been caused by such an act.
- The act must have been done.
- 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 such an act of the doer is likely to cause the death of the person injured
Example: A lays sticks and turf over a pit, with the intention of causing death or with the knowledge that death is likely to be causes. Z believing the ground to be firm treads on it, falls in it and dies. Here A has committed culpable homicide.
Murder: Murder is an aggravated form of culpable homicide. Murder inccludes culpable homicide but culpable homicide does not include murder in all cases. In order for a culpable homicide to maount to murder it should fall under the four clauses mentioned under Section 300.
A shoots Z with the intention of killing him. Z dies in the consequence. A commits murder
1. Grave and sudden provocation
2. Self defence
3. Act of public servant
4. Without premeditation
There is only a thin line of difference between the both. Culpable homicide is a wider term than murder.
Hope this clears your doubt.
