The defence had based its case on what went on inside the room for which there were no evidences. Only the two men knew what happened. But the prosecution based itself on witnesses after the accident and what went before Nanavati went to meet ahuja and his behaviour after the murder. There were evidences to back all the prosection points.

1. The scuffle: Ahuja was supposed to be wearing a towel when Nanavati entered. A scuffle followed. But when the body was found the towel was intact on the body. It had not loosened or fallen off. If there was a scuffle then it is highly improbable that the towel would have stayed on.

2. If the provocation for Nanavati was grave and sudden, he should have reacted immediately after Sylvia's confession. He did not. He was calm and collected. He drove down to the theatre and dropped his family there. Then he drove down to the naval base and obtained a gun under a false pretext. That he obtained a gun before meeting ahuja indicated that already there was a plan in his mind.

3. According to Prem Ahuja's servant Anjani's evidence, the three shots were fired in quick succession. There was no gap between them as put forth by the defence. And the entire incident took place in around 50 seconds ruling out the scuffle theory.

4. If it was an accident, then after the shooting when Mamie, hearing the shots came running and questioned Nanavati, "What is this? Nanavati simply walked out.
Why was it not explained to Mamie that it was an accident.

5. The dcp mumbai john lobo had testified that nanavati had in the first instance confessed that he had shot dead Nanavati.

6. The navy log book had it on record that Nanavati had obtained a gun and rounds from there.

7. Was Nanavati dazed. Evidence says no: It is not true that he was dazed. According to investigation, Nanavati had unloaded the revolver, taken his car down to Raj bhavan, confessed his cirme to provost marshall Samuel who suggested that he go and say all to john lobo.

Points out Mr chandrachud, he was so calm and collected that when the policeman at the station misspelt Nanavati's name as "Cawas" he corrected him and asked him to spell it with a "K": Kawas.

The murder was premeditated, the prosecution concluded. For the murder the sentence was life sentence or death sentence.

Nanavati appealed in the Supreme Court but it also returned the same judgement.

Nanavati was sentenced for life.
