AFTER a vote marred by violence, the fate of Taiwan's fourth nuclear power plant remained unclear as both the ruling and opposition parties claimed victory in a chaotic session of the Legislative Yuan. Legislative whips from both the ruling Kuomintang (KMT) and opposition Democratic Progressive Party (DPP) claimed that the 36-23 vote, with one abstention, was in their favour. The vote was technically on a motion whether to reconsider a motion put forward by DPP legislator Weng Chin-chu to freeze NT$7.5 billion (HK$2.18 billion) funds budgeted for the proposed plant in 1985. Due to confusion in the session, KMT legislative whip Liao Fu-pen recounted the ballots at a press conference, and stated that the result was 36 votes against reconsideration, 23 in favour, with one abstention. Mr Liao added that the result of the vote would be sent in a report, along with the entire budget for the Taiwan Power Company, to be voted on at the full session of the Legislative Yuan tomorrow. But DPP legislative whip Chen Shui-bien declared that the result was exactly the opposite, and said that ''no matter what the result of the vote, it does not put a period on the struggle against the fourth nuclear plant but is the beginning''. ''We are absolutely confident that we will win the final victory,'' Mr Chen declared. DPP legislator Hsieh Tsung-min said: ''We have a stronger chance of blocking the plant in the full session of the Legislative Yuan. If a secret ballot is held, several KMT members will vote against the plant.'' At least two legislators were injured in a melee that erupted during the counting of votes, as members jostled near the chairman's table. DPP legislator Huang Chao-hui was seen bleeding severely from his forehead and was sent to the emergency room of the National Taiwan University Hospital. KMT legislator Shih Tai-sheng, who was involved in the same melee, went to the same hospital later. The full-day session had been punctuated by sharp questioning of Economic Ministry and Taiwan Power Company officials on the necessity for the plant. The session was disrupted repeatedly by demonstrators who pushed past a police cordon into the meeting, raising banners and shouting slogans calling for a veto of the plant's budget. A spokesman from the Taiwan Power Company said he thought the DPP may attempt to boycott the state power firm's fiscal 1993 budget in tomorrow's debate. He added that invitations to bid for the proposed nuclear site at Kungliao, in northeast Taiwan, had already been issued and the company expected to receive bids by September.
