This article takes a constitutionalist perspective to focus on constitutional change in Taiwan and tries to uncover its quasi-normative significance from the long term development of constitutional order. It distinguishes three periods of constitutional change: the constitution-making process without the participation of Taiwan in 1946, the period of the Temporary Provisions from 1947 to 1991, and the constitutional amendments from 1991 to 2005. This article also points out that the phenomenon cannot be analyzed more precisely if we treat the Temporary Provisions as merely “Verfassungsdurchbrechung.” According to the typology of the constitution, from 1947 to 1991, both a nominal constitution and a semantic constitution coexisted. In fact, behind these superficial constitutional changes, a kind of “special constitutional change” was taking place in Taiwan during the last 50 years, because of both the great change in state territory and the people governed under the ROC constitution. After the transition to constitutional democracy, the first three constitutional amendments reinforced constitutional democracy, emphasizing democratic legitimacy and representation. After that, the constitutional amendments focused on the structure of the central governmental, and the people again became the instrument of constitutional change. From a constitutionalist perspective, we can see that, after the long term party-state regime and the power struggles on constitutional amendments during democratic transformation, the necessary social conditions for real constitutionalism were finally established in Taiwan. For the consolidation of constitutionalism in Taiwan, it is necessary to reform the constitution’s structure in order to mend the complicated relation between the Executive and the Legislative. However, there is still room for debate on grand-scale constitutional reform.
