THE Coroner's inquiry into the deaths of two power station workers came to an abrupt end yesterday after one of the jurors began acting like a lawyer and closely questioned a witness. The jury was discharged after legal representatives of the China Light and Power Company alleged the juror had misunderstood his role. Counsel Mr Michael Ford claimed the juror was asking questions designed to establish faults and deprive the company of a fair inquest. The inquiry into the deaths of engineers Mr Wong Kwong-yu, 38, and Mr Yip Ka-pui, 41, in an explosion at a Castle Peak power plant on August 28 last year started on Monday and had already accumulated substantial costs for the company and the Judiciary. Mr Ford said the juror appeared to be attempting to play the role of a prosecuting counsel, particularly by making a number of interventions, some in the form of questions, during the hearing. Coroner Mr Warner Banks reminded the juror, a businessman, that he was involved in an inquest, not conducting a prosecution. The juror then argued with Mr Banks about his power to question a witness, although the coroner said he had no right to do so when his turn was over. The juror was also seen approaching the Coroner's officer, Mr Patrick Li, after court on Wednesday, complaining that Mr Banks had been impatient with him and had restrained him from questioning. Mr Li said he prevented the juror talking to him and had left the courtroom shortly afterwards. Mr Banks decided there was a reasonable suspicion that a fair inquest would not be possible, even if actual bias was not established. The court will try to empanel another jury today so it can start again on Monday. The inquest is expected to run until May 5, when Mr Banks goes on holiday for two weeks. It will resume on his return, if necessary. As well as costing a six-figure sum, rescheduling the inquest will also disrupt other inquests. Instead of taking the new jury to the site, as had been done for the original jurors, it was decided a slide presentation would be arranged.
