The failure of the post-1997 administration to define 'national security' would cause confusion when the Public Order and Societies ordinances came into force, said Bar Association chief Audrey Eu Yuet-mee QC. She said it was hard for people to grasp the law when even Chief Executive-designate Tung Chee-hwa failed to offer a definition. Ms Eu, the association chairman, noted that Mr Tung had fallen short of saying whether shouting out 'release political dissidents' was against the principle of national security in a TV interview. Instead, he said the courts would be left to decide. Bar Council member Johannes Chan Man-mun said the police commissioner would be left with wide discretion. The Bar Association - among nine groups meeting Mr Tung to discuss the consultation document yesterday - also criticised the Societies Ordinance for covering too many organisations. It agreed with warnings that Mr Tung had neglected the principle of necessity in international covenants. The association suggested a separate law be made on political organisations at a later stage to reduce controversy in the Societies Ordinance. Pro-China politicians and prominent businessmen are drumming up support for the consultation paper to amend the ordinances. Supporters of the document include local NPC Standing Committee member Tsang Hin-chi, former executive councillor Sir Quo-wei Lee, former government official Nicky Chan Nai-keong, and provisional legislature member Elsie Tu. In all, 72 people have signed a statement supporting the proposal. Business interests, including the Chinese General Chamber of Commerce, and Textile Council of Hong Kong chairman Kenneth Fang, also signed.
