When the 4th NPC was convened in 1975, its main act was to adopt a new Constitution which eliminated the office of State Chairman and emphasized instead the leadership of the Communist Party over the state, including an article that made the party chairman Supreme Commander of the PLA in concurrence as Chairman of the party CMC.[23] The 5th NPC was convened two years early, in 1978, and a third Constitution was adopted, which also lacked the office of State Chairman. The office was finally reinstated in the fourth Constitution, adopted by the 5th Session of the 5th NPC in 1982.
