Fear of facing another political backlash could make senior officials afraid to implement policies if beleaguered Director of Housing Tony Miller is removed after this week's Legco no-confidence motion, a civil service union leader has warned. However, a Housing Department union said Mr Miller must go. It plans to present a petition at the Chief Executive's office today calling for his resignation. Accusing some parties of blowing up the issue, the Senior Non-Expatriate Officers' Association said civil servants should not bear political responsibility. 'Now that [Housing Authority chairwoman] Rosanna Wong has stepped down, Tony Miller has become the mark for all arrows,' association chairman Leung Chi-chiu said. 'If they [legislators] are pushing for political reforms and a ministerial system, they should do it separately rather than taking advantage of this issue to make a big story,' he said. Dr Leung said Mr Miller should not be held responsible for structural problems that existed before he took up the position. 'It's about the appointment and removal of civil servants. Unless we have political reforms, universal suffrage and a ministerial system, we should not bear political responsibility.' He said Mr Miller could be moved elsewhere if the situation remained deadlocked. 'But if the pressure of staying is too great, then it's up to him to consider.' Dr Leung said civil servants might develop reservations about implementing policy if they thought they might face a political backlash. But Lam Man-cheuk, a spokesman for the Alliance of Housing Department Staff Unions said Mr Miller and Secretary for Housing Dominic Wong Shing-wah should resign. 'It seems Mr Wong and Mr Miller do not have to shoulder any responsibilities.'
