However, the 1947 Constitution of the Republic of China, although retaining the architecture of the five-branch government, changed the Control Yuan to be a parliament chamber. Under the constitution, members of the Yuan (by now senators de facto) were elected from regional legislatures: 5 from each province, 2 from each direct-administered municipality, 8 from Mongolia (by 1948 only the Inner Mongolian provinces were represented), 8 from Tibet, and 8 from the overseas Chinese communities. As originally envisioned both the President and Vice President of the Control Yuan were to be elected by and from the members like the speaker of many other parliamentary bodies worldwide. Following the promulgation of the Constitution, the 178 first Control Yuan members elected by the regional legislatures convened in Nanking on June 4, 1948. The first Control Yuan then confirmed the leaders and members of the first Judicial Yuan and Examination Yuan. The transition from one-party state Nationalist government to constitutional government was hence completed.
