Samoa's Supreme Court has dismissed an attempted murder charge against a man who admitted assaulting his wife because she was having an affair with a taxi driver.

The Samoa Observer reported that Latai Pule was initially charged with causing bodily harm, being armed with a dangerous weapon, using threatening words and attempted murder.

He pleaded guilty to the charges of causing actual bodily harm and using threatening words but denied attempting to kill his wife.

The court found there was not enough evidence to convict Pule of attempted murder.

The court was told that Pule assaulted his wife in March after hearing that she was having an affair and that she had left their young son with a relative while she went drinking.

His wife said in her evidence that Pule had punched her several times and then used an electrical cord to try and strangle her.

Pule denied strangling her and the doctor who treated her told the court there was no visible evidence that she had been strangled.

Justice Leilani Tuala-Warren adjourned the matter until November 10 for sentencing.
