evidence: In the face of the Chinese communist threat, the National Assembly on April 18, 1948, added to the Constitution a set of Temporary Provisions Effective during the Period of Communist Rebellion. Promulgated by the National Government on May 10 of the same year, the Temporary Provisions which superseded the Constitution were designed to enhance presidential power during the emergency period of communist uprising. For example, the president was empowered during the Period of Communist Rebellion to take emergency measures to avert imminent danger to the security of the nation or of the people, establish an organ for making major policy decisions concerned with national mobilization and suppression of the Communist rebellion, make adjustments in the administrative and personnel organs of the central government, and initiate regulations governing the elections for additional seats in the three parliamentary bodies. In addition, the Temporary Provisions allowed for the president and the vice president to be re-elected without being subject to the two-term restriction prescribed in Article 47 of the Constitution. Following a radically changed domestic situation and reduced tension in the Taiwan Strait in the late 1980s, the National Assembly on April 22, 1991, resolved to abolish the Temporary Provisions with a view toward fostering the healthy development of constitutional democracy and enhancing social harmony and progress. On April 30 of the same year, President Lee Teng-hui announced that the Period of Communist Rebellion would be terminated on May 1.
