A HONG Kong delegate to China's National People's Congress has left the Airport Consultative Committee (ACC), accusing it of being ineffective. Lee Lin-sang declined an offer to renew his membership of the two-year-old ACC, saying he wanted to demonstrate his disappointment with the advisory body, despite government promises to strengthen its functions. Mr Lee, president of the New Territories Association of Societies, a pro-China umbrella organisation for trade unions said: ''The ACC can hardly perform its role as an advisory body. We can't delay the progress of the airport projects and can only attendbriefing sessions. ''Unlike the Basic Law Consultative Committee (BLCC), which really functioned as an advisory body, ACC members are only told of decisions after they have been made,'' said Mr Lee, who was a member of the now-defunct BLCC. Although the Government had pledged to provide more information, he said that would not help strengthen the ACC's role. Referring to the Government's decision to award the design contract for the airport passenger terminal to the highest bidder despite criticism, Mr Lee said: ''[The Government] would not take Hong Kong people's dissenting voices into account in making thedecision.'' Asked if, given his pro-China background, he had discussed his decision with Chinese officials, Mr Lee said he had informed only the ACC chairman, Wong Po-yan. ''It is not necessary [for me] to seek Chinese officials' views on every single move,'' he said. Mr Lee's decision came after a senior Chinese official, Chen Zuo'er, called on the Hong Kong Government to strengthen the role of the ACC. An ACC member, Wong Hong-hin, said he was surprised to hear of Mr Lee's decision, as he had kept a low profile. The deputy director of the New Airport Projects Co-ordination Office (NAPCO), Clinton Leeks, declined to comment. He said the majority of the ACC members would be re-appointed next month for another two years. To broaden the base of the 49-strong advisory body, the Government would slightly enlarge it by appointing new members, said Mr Leeks, who is also secretary to the ACC. He dismissed the idea that the appointment of more experts had been done to meet members' demands that the ACC secretariat should employ experts to advise ACC members. NAPCO already provided sufficient support to the ACC secretariat and it was not necessary to second government officials from other departments to serve in the secretariat, he said. According to the Memorandum of Understanding on the new airport projects, the British side should consult China on the membership of the ACC. Mr Leeks said the membership list was being finalised with the Chinese side. ACC member Victor Sit Fung-suen, who has walked out several times during ACC meetings criticising the lack of information, said he would continue to serve on the advisory body. ''I will not give up the chance to monitor the construction of the new airport, which is a big issue,'' said Mr Sit, a member of the Study Group on Infrastructure Development. More experts from different areas such as labour safety and environmental projection should be named to sit on the ACC, Mr Sit said. Another two members - Leung Kwong-cheong and Lau Kong-wah - who had often criticised the ACC for being powerless, said they would remain on the body.
