The governmental system, which is composed of the rules and institutions that are defined in terms of the distribution and regulation of the basic powers (legislative, executive and judicial) that an country has, is generally classified according to the relationship between legislative and executive. Within this classification, the independence of the judiciary is generally accepted. With the development of the doctrine of separation of powers, the discussions of the government system, which were carried out mainly through the parliamentary system and the presidential system, have gained a new dimension by the application of the semi-presidential system which reflects the characteristics of these two systems. Especially when we look at the content of the government system debates that have increased in the last quarter of a century in our country, it is seen that ideological discourses and people have come to the fore instead of the systems themselves being discussed. It is not possible, however, to reduce the expected state of affairs in many areas of our country, such as the change of the government system, to only individuals and ideological discourses, which can not solve the existing problems of the presently accepted government system. Therefore, in order for the discussions at the point of changing our current system of government to reach a final conclusion, Discussions should be considered at this dimension, taking into consideration the specific history, political conditions, social structure, economic and legal situation of each country, taking into account the country's preferred practices and country experiences. In this context, we aimed to discuss the effects of possible changes in the government system on the political, legal, democratic, economic and social structure of our country.
