Rule-of-law reformists led by Hu meet resistance from hardliners opposing fourth revision since 1982
Proposed revisions to the constitution have triggered a heated debate in the Communist Party over its supremacy as the ruling party.
The National People's Congress will almost certainly ratify amendments to the constitution at its annual session next month, adding protection of human rights and private property and enshrining former president Jiang Zemin's theory of the Three Represents.
But analysts said the debate on the amendments had highlighted sharp differences within the party on its status in relation to the constitution.
The revision, the fourth since the constitution was promulgated in 1982, has been shrouded in secrecy. The process was started last June by NPC chairman Wu Bangguo, but the debate proved so controversial the party barred public discussion.
A draft of the changes was passed by the NPC legal committee in October and a summary of the revision released to the public in December.
