A NUMBER of corrupt senior civil servants, who fled to Taiwan in the 70s or 80s, might return to Hong Kong if some of the ICAC's powers were ruled incompatible with the Bill of Rights, the commission said yesterday. The Independent Commission Against Corruption (ICAC) was referring to a clause in the Prevention of Bribery Ordinance under which people can be charged with living beyond their means. It has been under scrutiny since a District Court judge quashed a charge filed under this provision, saying it violated the Bill of Rights. ICAC community relations director, Eddie So Chuen-yee, said yesterday that the clause was one of the ICAC's 'most effective' weapons to fight corruption. A number of civil servants charged under the clause had fled to Taiwan over the past two decades, he said, and they might now feel free to return. The District Court ruling is subject to a Court of Appeal re-examination as the Attorney-General made an immediate application for an appeal afterward. Mr So said the ICAC had to be more open and accountable in future operations.
