Municipalities have a key role in the delivery of public services to individuals. The legislature has adopted the obligation to establish municipalities in provincial and district centers. There are different processes related to the establishment of municipalities at places other than provincial and district centers. According to Municipal Law, a referendum, which is one of semi direct means of democracy, must be held for establishing a new municipality or merging and inclusion of existing ones. Organizing referendums in accordance with constitutional principles on some issues related to municipalities indicates the importance that the legislature deems about referendums. This procedure is also compatible with the principle of subsidiarity which requires provision of public services to individuals by locally nearest public administrators and also meets the requirements of international norms that adopt the self-government of local government bodies. Although Municipal Law clearly regulates the bodies which can apply referendums under certain conditions it does not include regulations regarding the procedures and principles of application of referendums. In the process of making a new election law, it would be appropriate to make a regulation by reviewing the procedures and principles of referendums held in accordance with Municipal Law, in the light of Supreme Election Council (SEC) decisions. Although SEC named referendums held according to Municipal Law as “plebiscite”, it has recently abandoned this description and started to use the term “Referendum According to Municipal Law”. In this study, after the theoretical framework of the concept of plebiscite is explained was conveyed, referendums held according to Municipal Law are examined within the framework of the jurisprudence of the SEC on a systematic base.
