THE head of the Civil Service warned yesterday of problems if senior official postings became political appointments. Since the principal officials would serve through the term of Tung Chee-hwa's appointment and would not leave government until retirement, discussing the introduction of a ministerial system was unnecessary, Secretary for Civil Service Lam Woon-kwong said. Politicians, including Liberal Party chairman Allen Lee Peng-fei, have suggested the introduction of such a system although Mr Tung has repeatedly denied he planned to adopt it. The system would mean the Chief Executive would nominate his own team of officials, who would be non-civil servants, to formulate policies and be held responsible for them. The Civil Service could be kept politically neutral and not have to bear the brunt of future changes of policy under a new Chief Executive. In an interview with the Sunday Morning Post, Mr Lam said the recent fuss about such discussions was unnecessary. Under the Basic Law, the Chief Executive was allowed to appoint people from outside the Civil Service to form his team. Examples were Secretary for Justice Elsie Leung Oi-sie and Chief Justice Andrew Li Kwok-nang, who were credible people, he said. However, Mr Tung has also chosen most of his team from the Civil Service and the public generally accepted it. Mr Lam did not agree a change in the chief executive and policies would embarrass the Civil Service which might have to make a U-turn. 'Look, we have just had a change in sovereignty. How much bigger change can you have than that? We have just had a change in leadership from a British politician to a Hong Kong Chinese Chief Executive. 'I don't think anyone can accuse the Civil Service of not supporting the Chief Executive's agenda wholeheartedly.'
