The pro-democracy camp will call on Legislative Council president Rita Fan Hsu Lai-tai to convene a special council meeting on Wednesday inviting Chief Executive Tung Chee-hwa to discuss Beijing's decision to interpret key provisions in the Basic Law on Hong Kong's democratic reform. Legco is currently on its Easter break. The move, announced late last night, forms part of a four-pronged action plan, including a possible mass march on April 11, to oppose the National People's Congress Standing Committee's move to interpret two articles on the selection of the chief executive 'subsequent to the year 2007' and Legco 'after 2007'. It comes amid vigorous statements of support for the interpretation move by mainland legal experts and pro-Beijing figures who insist it will resolve disputes on constitutional development. The Basic Law Committee met in Beijing yesterday to prepare for the pending NPC Standing Committee meeting. The 22 pro-democracy lawmakers are planning a joint press conference tomorrow to express their views on Beijing's move. And pro-democracy district councillors will hold a press conference on Tuesday to discuss the issue. A candlelight vigil in Chater Garden is planned from Tuesday until April 6 to coincide with the period the NPC Standing Committee will study the Basic Law articles. Lee Wing-tat, the Democratic Party's vice-chairman, said another mass rally 'similar to the July 1 mass demonstration' was being studied. 'If the interpretations rule out universal suffrage in 2007, we will organise a march,' he said. Yesterday, Basic Law drafter Wang Zhemin for the first time clearly stated the interpretation would decide whether universal suffrage for the chief executive and the legislature could be introduced in 2007 and 2008. He said the interpretations would look at who could kick-start the process to introduce changes in electoral arrangements for the chief executive and the Legco. Wang Maolin, vice-chairman of the Legislative Affairs Committee of the NPC Standing Committee, criticised 'a small group of people' challenging certain provisions in the Basic Law. 'What are their motives or goals? I'm not very clear.' Hong Kong and Macau Affairs Office deputy director Chen Zuo'er said they were exercising their responsibilities under the Basic Law. Constitutional affairs chief Stephen Lam Sui-lung said the taskforce would meet Standing Committee representatives in Shenzhen on Tuesday.
