The Court of Appeal quashed their convictions. The Court of Final Appeal unanimously held that the provisions were justified and not unconstitutional, as they merely ban the mode of expressing one's message but do not interfere with the person's freedom to express the same message in other ways. The convictions and the binding over ordered by the Magistrate were restored. The decision was heavily criticised by Raymond Wacks in his article "Our Flagging Rights" in Hong Kong Law Journal. The Edison Chen photo scandal brought people to harbour doubts about the Control of Obscene and Indecent Articles Ordinance, which criminalizes the distribution of obscene articles and the distribution of indecent articles without proper warnings to persons under 18. On 2 February 2008, Commissioner of Police Tang King Shing warned that sharing the photos via email, and even storing them on a personal computer, might be illegal, even if there was no record of distribution. This inaccurate statement of the law led to the objection of Leung Kwok-hung, who accused the police of sowing confusion and creating an atmosphere of "white terror" among netizens. Leung urged Commissioner Tang to clarify whether merely keeping the pictures violated the law. The police later amended Mr. Tang's statement, saying that looking at the photos or emailing them between mutual friends isn't against the law, although posting them to Web sites is. The police's exuberance and inconsistency in cracking down on naked photos of celebrities triggered a public backlash from some netizens, who feel the police was curbing their freedom of expression in order to serve the powerful. The public reaction caused the government to table a review and public consultation of the Control of Obscene and Indecent Articles Ordinance. Another incident that concerned the freedom of expression in Hong Kong is the Citizens' Radio incident, in which several civil activists were charged for operating a radio station without a license granted by the Chief Executive in Council, contrary to section 8 and 20 of the Telecommunications Ordinance. Constitutional challenge of the licensing regime was unsuccessful. According to section 4 of the Places of Public Entertainment Ordinance (Cap. 172), no person shall keep or use any place of public entertainment without a licence granted under section 10 of the Ordinance. On 30 May 2010, the Hong Kong Alliance in Support of Patriotic Democratic Movements of China exhibited a replica of the Goddess of Democracy statue in Times Square in the absence of a license in order to commemorate the Tiananmen Square protests of 1989. It was confiscated by the police and after the ensuring scuffle two senior members of the Alliance were arrested for obstruction of a police officer in the due execution of his duty.
