Role of constitution in spotlight again as party's fourth plenum nears
The role of the constitution in legitimising and limiting the party's power has long been debated

Which reigns supreme - the Communist Party or China's constitution?
The political elite have struggled for more than two decades to find an answer. Liberals argue that a powerful charter limiting the actions of the government would bolster the party's credibility. Conservatives dismiss the idea as a Western import unsuitable for a socialist nation.
The question will be asked again next month when the party's Central Committee meets for its fourth plenum. Rule of law is expected to dominate the discussions, along with economic development.
Hopes that China would move towards constitutionalism have been stoked by President Xi Jinping. In a speech in December 2012, not long after he became head of the party, Xi repeated Article 5 of the charter, saying: "No organisation or individual has the privilege to overstep the constitution and law."
Xi echoed the idea in an address this month.
Similar pledges have been made in the past by top leaders. When Hu Jintao took over in 2002, he declared that "no organisation or individual can be permitted the special privilege of going outside the constitution and law".
