A Full bench of Apex Court held in a murder case as follow…
Virsa Singh Vs State of Punjab on 11 Mar 1958To put it shortly, the prosecution must prove the following before it can bring a case under s. 300 Indian Penal Code third clause.
(1) It must establish, quite objectively, that a bodily injury is present.
(2) The nature of the injury must be proved; these are purely objective investigations.
(3) It must be proved that there was an intention to inflict that particular injury, that is to say, that it was not accidental or unintentional, or that some other kind of injury was intended.
(4) It must be proved that the injury of the type just described made up of the three elements set out above was sufficient to cause death in the ordinary course of nature.This part of the enquiry is purely objective and inferential and has nothing to do with the intention of the offender. Once these four elements are established by the prosecution (and, of course, the burden is on the prosecution throughout) the offence is murder under s. 300, 3rdly. It does not matter that there was no intention to cause death. It does not matter that there was Do intention even to cause an injury of a kind that is sufficient to cause death in the ordinary course of nature (not that there is any real distinction between the two). It does not even matter that there is no knowledge that an act of that kind will be likely to cause death. Once the intention to cause the bodily injury actually found to be present is proved, the rest of the enquiry is purely objective and the only question is whether, as a matter of purely objective inference, the injury is sufficient in the ordinary course of nature to cause death. No one has a licence to run around inflicting injuries that are sufficient to cause death in the ordinary course of nature and claim that they are not guilty of murder. If they inflict injuries of that kind, they must face the consequences; and they can only
escape if it can be shown, or reasonably deduced that the injury was accidental or otherwise unintentional.
