THE number of Housing Authority members may be increased to meet the increased workload. Secretary for Housing Dominic Wong Shing-wah said yesterday that officials were reviewing the issue and might bring in more expertise if necessary. The Housing Authority now has 25 members. Lee Wing-tat of the Democratic Party and Bruce Liu Sing-lee of the Association for Democracy and People's Livelihood are set to table two private member's bills challenging the body's appointment system. The bills are to be gazetted next week and tabled to the Legislative Council for first and second reading early next month. Mr Lee's bill seeks to give Legco the final say on members appointed by the Governor. Mr Liu wants to increase the membership to 36, with six from Legco and 18 from district boards. However, Mr Wong said the idea of increasing membership preceded the bills. Neither bill was acceptable because of their serious consequences. The Housing Authority would become a 'political battlefield', he said, warning that the executive-led system would be undermined. 'It will be followed by other statutory bodies such as Hospital Authority and Mass Transit Railway Corporation,' Mr Wong said. The proposals by the two legislators did not guarantee a balanced representation of different interests, he said. There was 'nothing wrong' with the present line-up. Mr Wong defended his decision to keep under wraps the discussion papers of a think-tank he chairs on housing policy. He said immature ideas floated in the course of study would create confusion.
