Özet:

Political systems and regimes discussion lasted from Plato to Rawls. In this discussion process, the democracy model which is universally the only valid regime of all systems basing its legitimacy upon the people's will has been recognized as an indication of modernity in search of the ideal state order. The distribution or limiting of the power of government among the political powers is regulated by the constitutions of the countries. In democratic countries, there are three basic systems of government including parliamentary system, presidential system and semi-presidential system. Democracy can exist without parliamentary system and parliamentary system, in contrast, can exist without democracy just because the existence of Parliament does not guarantee democracy. Therefore, there is no direct relationship or proportion between the system of government and democracy or the state of law. This paper aims to defend these claims from an optimistic perspective. The main purpose of this study is to question the necessity and applicability of the presidential system which has been continually discussed in Turkey and provide a better understanding of the criticisms of the presidential system and some reservations about it. In this context, in the framework of the advantages of the presidential system, both the disadvantages of the parliamentary system and the positive aspects of the presidential system have been examined by making a literature review as well as making a comparison with the other countries historically and systems of government. Moreover, this paper also contains about the views of the various authors by making an analysis in the conceptual dimension. This work consists of three parts: the first section primarily focuses on the necessity of the presidential system. In the second part, the applicability of the presidential system in our country is considered in detail. The criticisms of the presidential system and some reservations against it are given in the third part.
