Lawyers for a 37-year-old Nepalese man whose life sentence for murder was upheld this week by the Supreme Court are preparing to file for a retrial, it was learned Wednesday.

On Tuesday, the nation's top court upheld a Tokyo High Court-imposed life prison term handed down in December 2000 to restaurant employee Govinda Prasad Mainali, who despite a district court acquittal was found guilty of strangling a woman in 1997 and stealing 40,000 yen of her money.

The woman was an employee of Tokyo Electric Power Co. She was found dead in a vacant flat next to an apartment where Govinda was living at the time of the slaying.
