Lawyers for the activists convicted this week of breaching the Public Order Ordinance said they are willing to fight all the way to the Court of Final Appeal, and drew comparisons with impending Article 23 legislation. 'Long Hair' Leung Kwok-hung, 46, of the April 5th Action Group, was on Monday convicted of holding an unauthorised assembly. Christopher Fung Ka-keung, 23, and Chris Lo Wai-ming, 27, were convicted of assisting in organising an unauthorised assembly in the first criminal conviction under the ordinance. Hectar Pun, who represented Fung in the Kowloon City court case, said he would argue the ordinance was unconstitutional and the prosecution was selective. Mr Pun said the law was too broad and ill-defined, and the convictions gave new cause to fear proposed laws on treason, sedition, subversion and secession under Article 23 of the Basic Law. 'I would argue whether the law is necessary and that it is too vague with too much discretion for police to interpret terms such as 'public order' and 'national security',' Mr Pun said. Chief Magistrate Patrick Li Hon-leung did not interpret the terms that give police discretion not to permit a public gathering under the law. He said it was a matter for the police. But Solicitor-General Robert Allcock rejected fears of vague legislation and selective prosecutions, saying Article 23 laws were always intended to be drafted as precisely as possible. 'The defendant in this case argued the law was contrary to human rights and the court expressly rejected this - it was for the courts to decide,' he said. Leung and Fung were arrested at their homes on May 9. Lo surrendered to police the same day for organising a Chater Garden rally of more than 40 people on February 10 without seeking permission from the police. Both Lo and Fung have indicated they will appeal against the conviction. Leung had initially planned not to appeal, but said that since the others wanted to, he would join them. Mr Pun and Wong Hin-lee, who represented Lo, have not been engaged for appeal yet as the activists are still in the process of seeking legal aid, but Mr Wong said that he had given his client advice. Leung represented himself.
