Indian Penal Code 1860 – Section 300 : Bharatiya Nyaya Sanhita – Section 101- Exception 1 – Before Exception 1 can be invoked, the accused must establish the following circumstances: (i) there was a provocation which was both grave and sudden; (ii) such provocation had deprived the accused of his power of self-control; and (iii) whilst the accused was so deprived of his power of self-control, he had caused the death of the victim- Sudden -(i) Whether the provocation was sudden or not does not present much difficulty. The word ‘sudden’ involves two elements. First, the provocation must be unexpected. If an accused plans in advance to receive a provocation in order to justify the subsequent homicide, the provocation cannot be said to be sudden. Secondly, the interval between the provocation and the homicide should be brief. If the man giving the provocation is killed within a minute after the provocation, it is a case of sudden provocation. If the man is killed six hours after the provocation, it is not a case of sudden provocation- Grave -(ii) A bare statement by the accused that he regarded the provocation as grave will not be accepted by the court. The court has to apply an objective test for deciding whether the provocation was grave or not. A good test for deciding whether a certain provocation was grave or not is this: “Is a reasonable man likely to lose self-control as a result of such provocation?” If the answer is in the affirmative, the provocation will be classed as grave. If the answer is in the negative, the provocation is not grave. In this context, the expression ‘reasonable man’ means a normal or an average person. A reasonable man is not the ideal man or the perfect being. A normal man sometimes loses temper. There is, therefore no inconsistency in saying that, a reasonable man may lose self-control as a result of grave provocation. A reasonable or normal or average man is a legal fiction. The reasonable man will vary from society to society. A Judge should not impose his personal standards in this matter. By training, a Judge is a patient man. But the reasonable man or the normal man need not have the same standard of behaviour as the judge himself. The reasonable man under consideration is a member of the society, in which the accused was living. So, education and social conditions of the accused are relevant factors. An ordinary exchange of abuse is a matter of common occurrence. A reasonable man does not lose self-control merely on account of an ordinary exchange of abuses. So, courts do not treat an ordinary exchange of abuses as a basis for grave provocation. On the other hand, in most societies, adultery is looked upon as a very serious matter. So, quotes are prepared to treat adultery as a basis for grave provocation- (iii) Loss of self-control – the question of loss of self-control comes up indirectly in deciding whether a particular provocation was grave or not. So, if it is proved that the accused did receive grave and sudden provocation, the court is generally prepared to assume that homicide was committed while the accused was deprived of the power of self-control. In some cases, it may be possible for the prosecution to prove that the accused committed the murder with a cool head in spite of grave provocation. But such cases will be rare. So, when the accused has established grave and sudden provocation, the court will generally hold that he has discharged the burden that lay upon him under Exception 1 to Section 300 IPC. (Para 17-26)
Indian Evidence Act, 1872 – Section 105 – It is for the accused who seeks to reduce the nature of his crime by bringing his case under Exception 1, to prove that the provocation received by him was such as might reasonably be deemed sufficient to deprive him of self- control, and that the act of killing took place whilst that absence of control was in existence and may fairly be attributed to it. (Para 27)
