Passage: At the 16th Party Congress held in 2002, the Standing Committee was expanded from seven to nine members. Some political observers speculated that the expansion was done in order to stack the new Standing Committee with loyalists of Jiang Zemin, though this characterization has been disputed. During Hu Jintao's term as General Secretary (2002 – 2012), the PSC could be understood as a "leadership collective" or a "joint presidency"; that is, essentially a body operating on consensus that executes powers normally granted to a single officeholder. The 16th Party Congress also saw Li Changchun gain a seat on the PSC without a formally defined portfolio, though he was widely considered to be the "propaganda chief". Huang Ju died in June 2007, becoming the first sitting PSC member to die in office since 1976. His vacancy was not filled ostensibly because it was only a few months preceding a Party Congress, making the body operate temporarily with an eight-member structure. The 17th Party Congress maintained roughly the same structure as the 16th.
