K M Nanavati v State of Maharashtra

Facts

Naval officer K.M. Nanavati's wife Sylvia confessed her affair with Prem Ahuja on 27 April 1959. Nanavati dropped his family at a cinema, drove to his ship, obtained a loaded revolver on a false pretext, went to Ahuja's flat, and shot him dead. The defence claimed the shots discharged accidentally during a struggle when Ahuja was asked whether he would marry Sylvia and look after the children. The jury acquitted 8:1, but the Sessions Judge disagreed and referred the matter to the High Court under Section 307 CrPC, which set aside the verdict and convicted; the Supreme Court affirmed conviction under Section 302 IPC.

Issues

• Whether the High Court, on a reference under Section 307 CrPC, could examine the whole evidence and set aside a jury verdict on the ground of misdirections in the Sessions Judge's charge to the jury.
• Whether a wife's confession of infidelity amounts to grave and sudden provocation under Exception 1 to Section 300 IPC so as to reduce murder to culpable homicide not amounting to murder.
• How the special burden on the accused under Section 105 of the Evidence Act to prove a General Exception operates alongside the prosecution's general burden to prove the offence.

Arguments

The prosecution contended that Nanavati, after the confession, deliberately armed himself, drove to Ahuja's flat and shot him in cold blood, the interval between the confession and the killing negating any sudden provocation. The defence argued he went only to have it out with Ahuja, took the revolver intending possible suicide, and that the shots went off accidentally during a struggle, invoking accident (Section 80 IPC) and, alternatively, grave and sudden provocation.

Held

The Supreme Court held that Section 307 CrPC confers wider powers than an ordinary appeal, allowing the High Court to consider the entire evidence and set aside a jury verdict vitiated by misdirections, of which several grave ones existed in the charge. On the merits, the Court held that even accepting the confession as provocation, the mental equilibrium had been restored: Nanavati went home, dropped his family at the cinema, drove to his ship, secured and loaded a revolver, and then proceeded to Ahuja's flat. By the time of the shooting the provocation had cooled and the act was the result of deliberation and calculation, not of a mind deprived of self-control. The plea of accident was rejected on the medical and ballistic evidence. The killing therefore fell within Section 300 IPC and the conviction for murder under Section 302 IPC was upheld.

Ratio decidendi

To attract Exception 1 to Section 300 IPC the fatal act must be traceable to a loss of self-control caused by grave and sudden provocation and committed before passion has cooled; where the accused has had time to regain composure and acts on deliberation, the killing is murder. The test of the 'reasonable person' and the absence of any cooling-off interval are essential, and the accused's special burden under Section 105 of the Evidence Act does not relieve the prosecution of proving the ingredients of the offence.

Significance

A celebrated landmark on the grave-and-sudden-provocation exception and the cooling-off principle, and effectively the last major jury trial in India, hastening abolition of the jury system. Its reasoning on Exception 1 to Section 300 IPC and the Section 105 burden of proof continues to be followed. The same principles now sit under Exception 1 to Section 101 BNS, 2023 (with murder under Section 103 and culpable homicide not amounting to murder under Section 105 BNS), and the burden of proving a General Exception under Section 108 of the Bharatiya Sakshya Adhiniyam, 2023.
