The judge presiding over the first court case to hear evidence by television link welcomed the introduction of the system but said it made the pace of proceedings 'too slow'. Judge Carlye Chu Fun-ling described the use of closed-circuit television in trials as an improvement which would give more protection to witnesses. 'They do not have to face the public and defendants. They can stay away from their attention,' she said. But the judge added that the use of the system could delay the progress of a trial. 'The case ran on very slowly. For example we have to warm up the system and there is equipment to be controlled,' she said. Judge Chu said hearing a case in which evidence was given by television was just like presiding over any other. She said she had not had any special feeling in court yesterday. Speaking outside court, Peter Nguyen, Director of Public Prosecutions, praised the system, which he said was useful and had worked very well. Crown prosecutor Laura Millar and defence barrister Fu Chong-sang said the system meant children could give their evidence in a more natural and relaxed manner.
