THE judge's ruling on a key section of the ICAC's legislation has cast a chill over anti-graft investigators who worry that it may lead to challenges to other sections. Assistant Director of Operations, Daniel Li Ming-chak, said no suspected corrupt civil servant would be charged under the controversial section 10(1)(a) of the Prevention of Bribery Ordinance until a decision on the appeal filed yesterday is made by the High Court. Mr Li said senior officers were 'very concerned and disappointed with' Wednesday's ruling, which said that the section - used to prosecute civil servants for living beyond their means - was in violation of the Bill of Rights because it required suspects to prove their innocence. 'There won't be any immediate action on similar charges,' Mr Li said. 'There are other ways of investigating corruption but I don't think there is any alternative to the Section 10 charge at the moment. Section 10 is a very unique offence and there is nothing similar elsewhere.' He said while the ruling amounted to 'a blow' against the organisation, it 'by no means marks the end of the Harry Hui case' and 'there is a difference between investigating and prosecuting'.
