A magistrate entered Hong Kong legal history yesterday when he allowed a video recording of a teenage girl's sex-case evidence to be played in court. It was the first case in which a recording has been submitted as evidence following the amendment to the Criminal Procedures Ordinance in July last year. Eastern Court magistrate Peter Line heard, in the 30-minute interview recorded in December, how the 13-year-old from Tseung Kwan O was allegedly assaulted four times last summer. But the girl still had to attend court for cross-examination. Mr Line allowed her to answer defence questions via the live television link. The teenager said that on four occasions in May and June last year, the three-year-old boy living in the flat next door asked her to play with him. But each time, she said, she was attacked by his uncle. She added that the 34-year-old decorator had fondled her breasts and private parts in front of the boy. The girl later told her teacher and her classmates. But Alfred Leung Tin-yau, defending, queried the credibility of the girl, who in her first complaint to police had accused the defendant of raping her. Under cross-examination she admitted she did not understand the difference between rape and indecent assault. The decorator denies four charges of indecent assault. The hearing continues.
