Section 299 of the IPC provides for the offence of culpable homicide. The actus for the offence of culpable homicide is death. As far as the question of the mens reus is concerned it has to seen three parts;
1) that it has to intentional causation of death; or
2) that there was intentional causation of bodily injury and such injury is likely to cause death;
3) that the accused knows that by such act it is likely to cause death
with reference to point 1st the prosecution burden is to prove a direct link between mind and death. Here the manner of committing the offence is not relevant if it can proved that the accused intended to cause death.
To know whether the accused intended to cause death or not the test of reasonable person will apply and it has to examined whether the accused has done all possible act and nothing has been left by him upon fortune so as to ensure to himself that death be caused with certainty.
For point second it has to be proved that the accused intended to cause bodily injury. Here the prosecution has to prove a link between mind and the particular injury which is caused by the accused. Thus the intention has to proved to be to cause particular bodily injury on particular body part of the victim. But the fact whether such injury is likely to cause death or not is not to be seen from the mind of the accused otherwise there would not have any difference between the 1st point and 2nd point rather it has to seen from the mind of the expert that is opinion of the medical expert has to obtained in reference to the fact whether such injury as caused to the victim is of such a nature that is likely to cause death of any reasonable person.
For point 3rd the test would be of the general rash conduct of the accused and here also objective test of reasonable will apply. Thus it has to seen whether if that reasonable person would have caused the same injury as is caused by the present accused than whether it can said in light of such injury that he knows his act be dangerous enough to cause death if that knowledge can be imputed upon the ordinary than that knowledge will also be imputed on the part of the accused.
