  • In the beginning, the matter was handed over in the hands of a jury they tried Nanavati under section 302 of IPC and found him not guilty of murder and held him liable under section 304A of IPC.
  • As there was misdirection in the judgment which leads to an erroneous decision and matter was thus referred to HC. The honorable court held that the jury set out its decision under the undue influence caused because of media and other factors which were later objected to. 
  • The accused plead a defense of Exception 1 under section 300 i.e., ‘Grave and Sudden Provocation but the Honorable court held that the accused was not working under grave and sudden provocation and was ‘the master of his own understanding’ at the time of the offense and did intentional killing in cool blood while planning for the same.
  • To plead the defense of grave and sudden provocation, the following conditions must be satisfied –
    1. It must be sufficient to deprive an ordinary or a reasonable man of his self-control so he might not be considered “the master of his understanding”.
    2. The fatal blow must be traced to the passion arising from provocation.
    3. The mode of resentment must bear a reasonable relation to the provocation.
    4. There must not have been sufficient time between the occurrence of the provocation and the killing for the accused’s blood to cool. The provocation to be a valid defense under this exception must be both grave and sudden.
  • The test of the grave and sudden provocation is whether a reasonable man, belonging to the same class of society as the accused, placed in the situation in which the accused was placed would act the same as the accused did. 
  • It is sudden when there was no time for the passion to cool down. If the act was done after the first excitement had passed away, and there was time to cool, it was a murder.
  • the accused must satisfy the court beyond reasonable doubt as the onus of proof lies on the accused, to prove his innocence, but Nanavati failed to do so.
  • The accused had made an SLP under article 136 and sent a letter of pardoning to the president at the same time.

Therefore, there was sufficient time for him to regain his self-control, even if he had not regained it earlier. His conduct shows that the murder was a deliberate and calculated one in the result, the conviction of the accused under section 302 of the Indian Penal Code and sentence of imprisonment for life passed on him by the 

High Court is correct, and there are no grounds for interference. The appeal stands dismissed.
