AN illegal immigrant mother and two young children must wait to see if their families can use the Bill of Rights on their behalf to argue against a removal order. Justice Jones yesterday reserved judgement after hearing arguments from Martin Lee QC for the three applicants, who the Immigration Department wants to remove from the territory. Deputy Crown Solicitor Bill Marshall QC appeared for the Government. It is understood that about 50 other similar cases are waiting for the judge's decision. The applicants are Lau Sin-ting, five, whose father, mother and brother are Hongkong residents; 22-month-old So Kam-cheung, who has been adopted by Hongkong residents; and Wong Chung-hing, who is married to a Hongkong resident and has five children with the right of abode in the territory; and their families. If the judge says Hongkong residents can invoke rights to family as guaranteed by the bill, it is likely that the Director of Immigration will have to reconsider all the cases. In his final submission yesterday, Mr Lee said the floodgates would not be opened if they succeeded. A ruling in their favour meant only that the immigration authorities should consider the effect of their decisions on the close relatives of the people who did not have the right of abode in Hongkong. Mr Lee said the Bill of Rights required the immigration authorities to consider these matters of constitutional importance before reaching their decision, but it did not guarantee any particular result. The authorities may still decide the right to family had not been violated because no family life had been established, Mr Lee said. It was a distortion to say the applicants' approach would lead to 400,000 immigrants coming to Hongkong.
