A BID by United Democrats Regional Councillors to pass a motion criticising a colleague who testified in Gilbert Leung Kam-ho's bribery case has hit a snag. Council chairman Cheung Yan-lung ruled out the motion yesterday because it was outside the remit of the council. Regional Councillor Fung Pak-tai was given immunity from prosecution and was one of the Crown witnesses in Leung's trial. Mr Sin said the council could debate the motion in the June 29 meeting if more than half of the councillors agreed to temporarily suspend the Standing Orders. He said they were still finalising the wording of the motion and might simply express regret about the corrupt 1991 election. The United Democrats said the motion would also urge the Government to amend legislation to disqualify people who admitted wrongdoing in court from public offices. Mr Sin was confident that more than half of the councillors would agree to suspend the Standing Orders. Meanwhile, a government lawyer has said that Gilbert Leung lost his public office immediately after he was convicted because his constituents' interests prevailed over his individual rights. The Government's decision to disqualify Leung, who is appealingagainst conviction, and to hold by-elections has been questioned by some people in the community. A district board member said it was unfair, because Leung would not be able to regain his seats even if the ruling was overturned. The Legco by-election is scheduled for July 28. The lawyer said the overriding principle was that the interests of Leung's constituents should not be unrepresented. Electors should not be disenfranchised because of the activities of legislators. A Constitutional Affairs Branch spokesman said allowing a member serving a sentence to retain his seat pending his appeal would create considerable uncertainties which would not be in the interests of his constituency and the wider public. The Government declared in last Friday's Gazette that Leung's office became vacant on June 1. The lawyer also predicted that the chance of success of a judicial review of the administration's decision was low. Leung was disqualified from the Heung Yee Kuk yesterday.
