LEGISLATORS yesterday cast doubts over whether the proposed old-age pension scheme would come to fruition, and said they thought it would eventually be deemed infeasible by the administration. Many were convinced the proposal was a stalling tactic and that it was meant to fend off calls for a central provident fund. And they were critical of the administration's refusal to go ahead with a compulsory retirement scheme. Several independents accused the Government of acting irresponsibly in introducing a scheme before being fully aware of the ramifications. Members yesterday voted 27-2 for the motion, moved by Pang Chun-hoi, which called on the Government to draw up details of the scheme and put in place as soon as possible a mandatory retirement scheme. Accountant and appointed councillor, Marvin Cheung Kin-tung, said: ''I fail to see any evidence that the Government has done sufficient homework to come to a final policy on this matter. ''The public is not given any back-up information or proof that the Government has evaluated fully the implications of the [old-age pension] suggestion the Secretary for Education or Manpower raised.'' He said: ''Will we see yet another U-turn when Government catches up with its homework and discovers the full implications of its latest proposal?'' Dr Leong Che-hung of Meeting Point said the about-turn was mind-boggling. He wondered whether the administration would scrap it in a year if experts found problems with it. Vincent Cheng Hoi-chuen said he was not convinced the pension scheme outlined by the Government was the only way forward and did not think the Government had thought the whole issue through nor fully understood its implications. Chim Pui-chung believed the proposal went against the Government's long-cherished principles of low tax and non-interference. United Democrat Lau Chin-shek said the Government was introducing the proposal simply to defuse members' requests for a central provident fund. But he said their position remained as firm as ever. Liberal Party member Ngai Shiu-kit said the scheme exceeded the scope of social security because it was giving benefits to everyone regardless of their needs. ''It is pushing us along the slippery road towards a welfare state,'' he said. But Tam Yiu-chung of the Democratic Alliance for the Betterment of Hong Kong said the Government's proposal was heading in the right direction of social insurance. Noting that society was not prepared for the concept, Mr Tam said some of the responses had been emotional and instinctive. His position was supported by Frederick Fung Kin-kee and Jimmy McGregor. The Secretary for Education and Manpower, Lam Woon-kwong, denied the Government had done a U-turn on the issue. He said it had arrived at the decision only after careful deliberation and denied it was a step towards a welfare state as it was only meant to provide basic security for the elderly. Mr Lam insisted that the proposal was the only option that could deal with the problem of financial security for old age within a reasonably short time.
