Outgoing Liberal Party vice-chairman and legislator Ronald Arculli yesterday denied he had ever betrayed the interests of the real estate and construction functional constituency. Some developers are said to be unhappy with his performance, but Mr Arculli said: 'Had [I betrayed them], the commerce body could have sponsored a motion of no-confidence in me.' Mr Arculli, who on Tuesday announced he would not stand for Legco in September, said a representative of a functional constituency should not blindly follow its wishes. 'Would that not give the public an impression the sector was always only looking after its own interests?' he asked. Mr Arculli said differences could easily arise between a legislator and his functional constituency on issues not directly related to that constituency. He said there would be people who held different views from his but he did not feel he had done anything during his past nine years' service in the sector that would have prompted it to block him from standing for re-election. Asked about who should succeed him in the constituency, he said: 'I hope he can be a legislator with credibility within and outside the legislature.' Mr Arculli also spoke of the decision in 1998 by Secretary for Justice Elsie Leung Oi-sie not to prosecute former Sing Tao chairman, Sally Aw Sian, who was named as a co-conspirator in a circulation fraud case at the now-defunct Hongkong Standard. The case provoked Mr Arculli to walk out of the Legco chamber in March last year during a vote of no-confidence in Miss Leung. He later said he had wept in frustration over Miss Leung's decision not to prosecute Ms Aw. His constituents had expected him to vote in favour of Miss Leung. Mr Arculli said the rule of law would not be destroyed by a single error. 'A case or half a case will not kill the rule of law because our foundation [in the common-law legal system] is very strong. But that doesn't mean there will not be accidents from time to time.' Although his walkout appeared to demarcate a souring of his relationship with the Liberal Party, Mr Arculli said he had no bad feelings towards Miss Leung. 'It's not that I hate Leung Oi-sie. I absolutely don't hate her. It's only that, as a lawyer looking at the issue from a professional point of view, I found her in the wrong. I dare not say I would be flawless.' Mr Arculli believed Miss Leung would not act the same way if the same case arose again. He also had advice for the Chief Executive, saying Mr Tung should work on presentation. 'We all know the Chief Executive does not like to 'perform in a show'. He likes to do pragmatic work. In fact, what the Government can do for the economy is limited. However, he has failed to sell this message.' Learning of Mr Arculli's decision upon returning home from holiday in Japan, Democratic Party chairman Martin Lee Chu-ming said: 'It's very much a pity. Ron is very experienced and has endeavoured to maintain the dignity and operation of the entire legislature. Few members did so. He cares very much about the legislature and is very hardworking at bills committees.'
