The offices of Chairman and Vice-Chairman were officially scrapped under the Constitution after almost 7 years of functional non-existence since the purge of Liu Shaoqi.
While the 1954 constitution had previously restricted any mention of Chinese Communist Party to preamble, leaving a document with a nominally liberal democratic text, the 1975 Constitution witnessed an integration (in part) of party and state.
The Constitution states that the People's Liberation Army, the armed services of the PRC, is to be controlled by the Chairman of the Chinese Communist Party and that the Premier of the State Council is to be elected by the National People's Congress on the motion of the Central Committee of the Chinese Communist Party.
The 1975 Constitution remained in effect for about three years due to the death of Mao Zedong and the rise of Hua Guofeng the following year, the latter of whom ordered its replacement with a new document to solidify his position as Mao's successor.
