Previously Section 299 of the Indian Penal Code (IPC)

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.

Illustrations.

(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.
(b) A knows Z to be behind a bush. B does not know it. A, intending to cause, or knowing it to be likely to cause Z’s death, induces B to fire at the bush. B fires and kills Z. Here B may be guilty of no offence; but A has committed the offence of culpable homicide.
(c) A, by shooting at a fowl with intent to kill and steal it, kills B, who is behind a bush; A not knowing that he was there. Here, although A was doing an unlawful act, he was not guilty of culpable homicide, as he did not intend to kill B, or to cause death by doing an act
that he knew was likely to cause death.

Explanation 1.—A person who causes bodily injury to another who is labouring under a disorder, disease or bodily infirmity, and thereby accelerates the death of that other, shall be deemed to have caused his death.
