MORE than 200 asylum-seekers can take their battle against the Government to the Privy Council, the Appeal Court ruled yesterday. Mr Justice Bokhary said the 'dimensions' of the case justified allowing the boat-people to plead their case in London. 'A very large number of people are concerned, and concerned in a way vital to them,' he said. Nguyen Tuan Chong, 24, and 228 others have accused the Government of breaking the law by refusing to screen them for refugee status and resettlement. The asylum-seekers are ethnic Chinese who fled to the mainland after upheavals in Vietnam in the late 1970s. They have been held in detention camps since arriving in Hong Kong in the late 1980s and early 1990s, claiming they were persecuted or evicted. The Government said there was no need to screen them for refugee status under the Immigration Ordinance as they are Ex-China Vietnamese Immigrants. The Appeal Court yesterday allowed both sides two months for preparations and the dispatch of records. 'Meanwhile, they are in custody awaiting return [to China] as illegal immigrants,' Mr Justice Bokhary noted. 'It is quite amazing.'
