A bankrupt businessman jailed for murdering his ex-wife, stuffing her body in a suitcase and dumping it in Perth's Swan River has appealed his conviction, arguing the timeline did not fit and key financial documents were not revealed at trial.
Ah Ping Ban was found guilty of murdering 58-year-old Annabelle Chen at her Mosman Park home in 2016 by bashing her with a blunt object and using a scooter with a breadboard attached to move the luggage.
He was sentenced in the West Australian Supreme Court to life behind bars with a minimum of 20 years.
The former couple's daughter Tiffany Yiting Wan was convicted of being an accessory and sentenced to four years and 10 months in jail.
Ban lodged an appeal, which was heard on Friday.
His lawyer Simon Watters presented several grounds of appeal, including that the timeline of events did not fit, claiming the evidence did not establish beyond reasonable doubt Ms Chen was killed after Ban arrived in Australia from Singapore.
Mr Watters also argued financial documents regarding Ms Chen's wealthy estate were not raised at trial, which showed Wan was her mother's beneficiary.
He further argued there was a miscarriage of justice because the trial judge failed to adequately direct the jury it was open to them to find both the accused not guilty.
The appeal decision will be handed down at a later date.
At the trial, Ban and Wan blamed each other.
Ban claimed Ms Chen was already dead when he arrived in Perth on June 30 and he only helped dispose of the body at the Fremantle Traffic Bridge.
But Wan said she heard her mother scream and her father later confessed to killing his ex-wife with a cast iron paperweight.
Two fishermen found Ms Chen's body days later but her identity remained a mystery for two months until Wan reported her missing.
