The Communist Party's constitution must reflect changes in the party, an academic has said. The suggestion by Communist Party School Professor Ye Tuchu, which was published in the latest issue of the party's magazine, Outlook, is another indication leaders are pushing for a revision of the constitution at the 16th Party Congress. 'Like any other legal and political systems, the party constitution is not isolated [to external developments] and immutable,' the report said. The party constitution was more than a legal document, the report said. It should be a document of 'vitality, principle and hope'. It is widely expected that during the congress due this autumn, the party constitution will be revised to include President Jiang Zemin's 'Theory of the Three Representatives', joining Mao Zedong Thought and Deng Xiaoping Theory as the guiding dogmas for the party. Mr Jiang's idea holds that the party should represent the most advanced production forces - including capitalist entrepreneurs - the most advanced culture and the interests of the masses. In the report, Professor Ye cautioned that revisions of the party constitution must also take into account the 'wishes of party members and public aspirations'. Professor Ye said the party constitution should 'concentrate on establishing the general directions and basic tenets for the party, and it is not necessary to dwell on tiny details and lose focus'. He emphasised that the charter should only incorporate provisions which have been proven 'mature' and 'effective' and avoid suggestions which had not been tested. 'We should not turn our party constitution into a collection of wishful thinkings,' the professor wrote. 'It cannot be built on empty slogans or useless lies.'
