High Court Judge Douglas Yau Tak-hong stated that the defendant, Chung Pui-kei, 38, showed no remorse and was at high risk of reoffending. The judge condemned the assaults as "extremely despicable," highlighting Chung's abuse of his position as a carer and the betrayal of trust placed in him by the employer and the victim's family.

The victim, who has an intellectual developmental disorder equivalent to a nine-year-old's mental capacity, testified that she had refused Chung's advances and expressed discomfort but feared speaking out. The judge noted that Chung's decision to plead not guilty prolonged the victim's ordeal by requiring her testimony.

Chung's defense, which suggested semen found on the victim's bedsheet was transferred through his sleepwear while he slept, was dismissed by the judge as "absurd" and a waste of court time. The jury found Chung guilty of five counts of rape, with the 13-year sentence reflecting the severity of the crimes.
