The government is moving quickly to seek an interpretation of the Basic Law on the chief executive's term, prompted by lawmaker Albert Chan Wai-yip's planned legal challenge. The administration is expected soon to ask the nation's top legislature to interpret the provisions of Hong Kong's mini-constitution at its meeting next month. The South China Morning Post reported last Wednesday that Secretary for Justice Elsie Leung Oi-sie was understood to have privately told local legal experts that the government would seek an interpretation, but its timing had not been determined. But sources said yesterday that Mr Chan's announcement last Thursday that he would seek a judicial review of government changes to a law on the term of the next chief executive had forced the government's hand. 'We were told the government will make the request soon to the National People's Congress Standing Committee for an interpretation of the Basic Law at its meeting scheduled for next month,' a source said. The government's amendment is to be tabled on April 6.
