KUALA LUMPUR - He claims that his marriage had been on the rocks for a long time.
Dr Jitweer Singh Ojagar Singh also claimed in court that his wife Shento Kaur Jaswant Singh was an alcoholic and drug dependent.
However, the evidence produced in court against him for the murder of his wife seven years ago was far more convincing.
He was sentenced to death by the High Court yesterday.
Justice Asmabi Mohamad ruled that the defence had failed to raise reasonable doubt against the prosecution's case.
"Thus, I sentence you to hang by the neck till you are dead," she said, when handing down the decision yesterday.
Justice Asmabi said her hands were tied by the mandatory provision of the law and Dr Jitweer had the right to appeal.
"If I am wrong, the upper courts will reverse my decision. The judgement is to the best of my ability based on evidence placed before me," she said.
In her ruling, she said Dr Jitweer testified that his marriage had beenfailing and the victim was an alcoholic and drug dependent but failed to raise the issue when his son Dharamjit and his brother Kurdip Singh were testifying.
Justice Asmabi said the theory that the victim died due to "positional asphyxia" was an afterthought.
