The government last night ordered the examination of all polling stations' accounts of voting in four functional constituencies. The number of ballot papers counted exceeded those issued to registered voters in all four - the accountancy, social welfare, labour and health services constituencies. The Electoral Affairs Commission ordered the Registration and Electoral Affairs Office to conduct the examination across all 501 polling stations. Secretary for Constitutional Affairs Stephen Lam Sui-lung said Mr Justice Woo Kwok-hing, chairman of the Electoral Affairs Commission, was due to explain the situation today. The order came as at least three candidates from functional constituencies filed complaints before the commission, with one calling for the results in the accountancy constituency to be declared void. Some candidates in geographical constituencies complained that several ballot boxes had been opened without the presence of candidates or their agents. Others accused electoral officers of barring election agents from entering polling stations when they closed at 10.30pm on Sunday. Newly elected lawmaker Ronny Tong Ka-wah vowed to pursue the matter when the new Legco term starts next month. Mr Lam said the decision to open ballot boxes after they had been resealed, to create space for more ballots, 'was taken by the Electoral Affairs Commission according to its statutory powers'. He said the commission would thoroughly investigate complaints by some election agents that they were asked to leave polling stations at 10.30pm. A spokesman for the Registration and Electoral Office said they had received 1,628 complaints on election day. The Independent Commission Against Corruption, meanwhile, has received 87 complaints about the election up to Monday - 77 of them pursuable. The 77 included 22 about bribery of voters; 14 voting offences; 14 related to publishing false or misleading statements about candidates; and seven on election advertisements that made false claims about support. ICAC Commissioner Raymond Wong Hung-chiu said the number of complaints was due to the 'fierce' competition, 'but I think it was still a clean election'. The Ombudsman received 10 complaints but would reveal no details.
