After the victory in Xinhai Revolution, the Nanjing Provisional Government of the Republic of China, led by Sun Yat-sen, framed the Provisional Constitution of the Republic of China (simplified Chinese: 中华民国临时约法; traditional Chinese: 中華民國臨時約法; pinyin: Zhōnghuá Mínguó línshí yuēfǎ, 1912), which was an outline of basic regulations with the qualities of a formal constitution.
On 11 March 1912, it replaced the previous organizational outline of the government and was in effect as the supreme law. It was later replaced by a constitutional compact instituted by Yuan Shikai. However, it was restored once again on 29 June 1916, by President Li Yuanhong.
The Constitutional Protection Movement launched by the Military Government of the Republic of China in Guangzhou on 10 September 1917, was intended to "protect" this provisional constitution. In Beiyang Government, this provisional constitution was replaced by Cao Kun's constitution on 10 October 1923. In the Nanjing Government, this constitution was not replaced until 1 June 1931, when the Provisional Constitution of the Political Tutelage Period was announced, although the old constitution was already rarely discussed after the establishment of the Nationalist Government on 1 July 1925. From 1928 onwards, the Nationalists were operating under an Organic Law that had an ambiguous relationship with the 1931 Provisional Constitution as it was not completely superseded.
- The government system was to imitate the French presidential cabinet: the Senate at the time wanted to restrain Yuan Shikai's ambitions, and they changed the presidential system to a parliamentary system so that Yuan would be turned into a figurehead.
- The general principles were to be outlined concisely, regulating the fundamental elements of the nation in principle.
- The presidential election would still be held in the Senate according to the organizational outline of the provisional Government.
- The Judiciary system was completely independent, which matched the principle of separation of powers: the provisional Constitution regulated that the provisional president and the Minister of the Judiciary would appoint judges separately. Trials were to be administered by judges independently without the intervention of the government.
