People's Court are all elected by the NPC on the nomination of the Presidium of the NPC. The Premier is elected by the NPC on the nomination of the President. Other members of the State Council are elected by the NPC on the nomination of the Premier.

In order to represent different segments of the population and bring in technical expertise, the CPC does ensure that a significant minority of people's congress delegates are either minor party members or unaffiliated, and there is tolerance of disagreement and debate in the legislative process where this does not fundamentally challenge the role of the CPC. CPC regulations require members of the
