Regulating the power of the Chief Executive to seek interpretation of the Basic Law would help ease the jitters of the judicial and legal communities, a Basic Law Committee member said yesterday. Professor Albert Chen Hung-yee, law faculty dean at the University of Hong Kong, said a constitutional convention governing the procedures and contents of interpretation that could be sought by the Chief Executive should be established. The controversy over Tung Chee-hwa's decision to seek an NPC Standing Committee reinterpretation had shown 'there's a gap in the Basic Law', he said. 'The legal community is now not so much worried about whether the Standing Committee will abuse the power, but if the SAR Government will,' Professor Chen said. 'If there's no restriction, there will be uncertainty in law and judges will become worried.' Professor Chen suggested majority approval be required from the Legislative Council and local deputies of the National People's Congress for any request from the Chief Executive. Matters for interpretation should be related solely to mainland-SAR relations, he said. Another Basic Law Committee member, Raymond Wu Wai-yung, however, said such a mechanism was unnecessary. He said it would impose restraints on the powers of the NPC Standing Committee. 'It's unreasonable to add a rider to the legislative interpretative power of the NPC Standing Committee which is clearly stated in the Chinese constitution,' he said. But Professor Chen said the Standing Committee's power would not be curbed by safeguards. 'Even if the Chief Executive does not seek interpretation, the Standing Committee is always vested with the power to do so,' he said.
