Today's third day of hearings in the corruption trial of the wife of Taiwanese President Chen Shui-bian is expected to go ahead without the ailing first lady. Chief prosecutor Chang Hsi-huai, who has been under mounting pressure from lawmakers of the ruling Democratic Progressive Party to drop the case, will also be absent. First lady Wu Shu-chen and Mr Chang had both called in sick and were not expected to appear at the hearing, officials said yesterday. Doctors for Wu, a paraplegic, yesterday said she was still unfit to stand trial after collapsing two weeks ago at the start of court proceedings described by local media as Taiwan's 'trial of the century'. Wu asked for a leave of absence last Friday for the same reason. But after treatment, 'her temperature and heartbeat have returned to normal, her blood pressure is still unstable and will drop sharply in the wake of cold weather and changes in posture', said the National University Hospital. Wu was charged with forgery and the embezzlement of NT$14.8 million (HK$3.5 million) in state funds by prosecutors in November. Since condemning Mr Chang and his colleagues for making the ailing first lady appear in court, DPP lawmakers have launched a smear campaign against the prosecutor, alleging he works for the mainland and is unfit to take part in the trial. The allegations had exerted immense pressure on him, resulting in an emotional breakdown, his colleagues said. 'Prosecutor Chang has taken advice from doctors to recuperate at home,' said Taipei District Public Prosecutor's Office spokesman Lin Chin-tsun. He said the office had no plan to replace Mr Chang, who would return to the trial when he felt better. The reports said his colleagues were forced to ask his wife to take him home on Wednesday. Meanwhile, Huang Chun-ying, the defeated Kuomintang candidate in the mayoral election on December 9 in Kaohsiung, filed two lawsuits at the Kaohsiung District Court yesterday. The first seeks to nullify the election result that favoured his DPP opponent, Chen Chu, and the second seeks to invalidate the election, which he claimed was flawed. Mr Huang lost the election by a narrow margin.
