K.M. Nanavati v. State of Maharashtra

AIR 1962 SC 605

Facts

Commander K.M. Nanavati was a naval officer married to Sylvia.
Sylvia confessed that she had an intimate relationship with Prem Ahuja.
Nanavati asked whether Ahuja intended to marry her and care for the children, but Sylvia could not assure him.
Nanavati drove Sylvia and the children to a cinema.
He then went to his ship and obtained a revolver and ammunition on a false pretext.
He loaded the weapon and drove first to Ahuja’s office and then to Ahuja’s residence.
Ahuja was found dead in his bedroom from gunshot wounds.
Nanavati claimed that:
he intended only to ask about Ahuja’s intentions;
the revolver discharged during a struggle;
alternatively, he acted under grave and sudden provocation.
A jury acquitted him, but the Bombay High Court convicted him of murder after a reference by the Sessions Judge.

Whether Ahuja’s death was accidental during a struggle.
Whether Sylvia’s confession constituted grave and sudden provocation continuing until the shooting.
Whether sufficient cooling time and Nanavati’s intervening conduct excluded Exception 1 to Section 300.

Grave and sudden provocation reduces murder only where:
the provocation would cause a reasonable person to lose self-control;
the accused actually lost self-control;
the killing occurred before passion cooled.
The court considers:
lapse of time;
intervening conduct;
planning;
procurement of a weapon;
whether fresh provocation occurred.
Provocation that has cooled into motive for revenge does not attract the exception.
Deliberate preparation strongly indicates regained self-control.
The burden of establishing an exception lies on the accused on a balance of probabilities, while the prosecution must prove murder beyond reasonable doubt.

Sylvia’s disclosure was capable of causing emotional shock.
However, Ahuja was not present when she made the confession.
Nanavati did not immediately encounter and attack him.
Instead, he:
drove his family to a cinema;
travelled to the naval ship;
obtained a revolver through a false explanation;
loaded it;
performed some official work;
drove to Ahuja’s office and residence.
Approximately three hours elapsed.
These organised steps demonstrated reflection and planning rather than a continuing uncontrolled impulse.
The Court rejected the claim that his self-control remained suspended throughout.
Any original provocation had become a reason for deliberate retaliation.
The alleged question-and-answer exchange with Ahuja did not supply fresh legally sufficient provocation.
The physical evidence also did not support an accidental discharge during a struggle.
Multiple shots and surrounding circumstances were more consistent with intentional shooting.
The jury had been materially misdirected regarding the burden and requirements of provocation.
The High Court was therefore justified in reassessing the case.

The Supreme Court upheld Nanavati’s conviction for murder.
The three-hour interval and deliberate procurement of the loaded revolver provided ample cooling time.
Exception 1 to Section 300 did not apply, and the shooting was treated as deliberate and calculated.
Use this case for: provocation loses its mitigating effect where cooling time and planned conduct show that the accused regained self-control and acted in revenge.
