POLICE have taken the unprecedented step of using the Public Order Ordinance to bar local paper recyclers from holding a massive vehicle rally during the morning rush hour in Central tomorrow. Despite the Government's refusal, the Hong Kong General Association of Recycling Business has vowed to go ahead with the rally, saying up to 100 trucks will travel through Central between 8am and 10am. Human rights advocates have urged the group to appeal against the government decision, warning the precedent would lead to more suppression of expression. But the Deputy Regional Commander for Hong Kong Island, Tang King-shing, said the ban was only intended to prevent traffic chaos and was not underscored by any political motive. 'In order to maintain public order and ensure the rights and freedoms of the public, we decided to turn down the procession application,' Mr Tang said. The Hong Kong Human Rights Monitor disagreed that the group should be banned from using the roads to express themselves. 'Any vehicles can run on the roads without producing a reason, I can't see why they should be excluded,' the watchdog's director, Law Yuk-kai, said. 'They should appeal over the rejection.' The April Fifth Action Group insisted there was a political consideration behind the ban. 'After the precedent is set, the Government can ban any protests according to its political interest,' said group member Leung Kwok-hung. It is the first time police have objected to an application for a procession under the Public Order Ordinance since its controversial amendment became effective from the handover. It gives police powers to intervene in a demonstration on grounds of national security. A representative from the Hong Kong General Association of Recycling Business said the rally would go on. 'We'll only be outraged and the situation will get stiffer if you don't allow us to express ourselves in a peaceful way,' he said. The maximum penalty for violation of the Public Order Ordinance was five years in jail, police warned. The planned rally route includes Cotton Tree Drive, Queen's Road Central, Bonham Strand, Hillier Street, Connaught Road and Harcourt Road. During a demonstration outside the Central Government Offices, a petition will be presented to Tung Chee-hwa.
