Chaos broke out in the High Court yesterday when an outspoken member of the public demanded an audience with the judge. A middle-aged woman began shouting for Mr Justice Patrick Chan Siu-oi during a brief adjournment in a civil trial. When the judge asked what the fuss was about, she responded: 'I have some doubt about the government system.' 'I too have doubt,' Mr Justice Chan said. 'But I am here to try a case.' The woman said she did not understand the workings of Hong Kong's legal system. 'I understand that you can make arrangements to explain the judicial system to me afterwards,' she said. The judge retorted that he was 'not a public relations officer'. He ordered her to 'sit there and behave'. The woman, who was not related to any of the parties in the trial, began muttering angrily to others in the gallery. The case before Mr Justice Chan centred on a family dispute. Sum Kam-wun, 77, took his relatives to court after they tried to evict him from his home of 20 years. 'He told the court that his father's ghost told him to look for a lawyer,' lawyer Albert Yau, for the relatives, said. Mr Sum's mother-in-law, Chan Fok-tai, was the registered owner of the Ma Wan property, Mr Yau said. Mr Sum is fighting Chan's eldest daughter and nephew for control. 'They say you have been a licensee only and they are now asking the court to evict you,' the judge said, summarising the case to the old man. 'In the meantime, your mother-in-law has died and your sister-in law has taken over.' The woman died on February 23, 1994, aged 93, leaving the land to her daughter. The old man, who was unrepresented, protested that he had invested years of life and labour in the house. He accused his relatives of making a 'false deed' to rob him of the property that was rightfully his. But the judge summarised: 'Your mother-in-law told you if you repaired the house you could stay there. The building you put up was financed by the mother-in-law.' The trial continues.
