The protection of personal data relates to the protection of privacy, the right to privacy, and the right to free development of personality. With these aspects, it constitutes one of the basic requirements for the realization of human rights and freedoms and the principle of the rule of law. There are principles and rules developed within the scope of national and international law in this field. Judicial review, especially the constitutional judiciary, has an important responsibility for the implementation of the protection of personal data. This study aims to analyze the implementation of protection of personal data within the framework of the norms regarding the protection of personal data as a human right in the light of case law and current decisions of the Constitutional
Court. In addition to these, suggestions are made on legal regulations and additional measures needed for a more effective implementation in this area. In this context, first the conceptual framework is analyzed. Then, the regulations on the protection of personal data in international law and Turkey’s national legislation are discussed. Finally, efforts to protect this right and additional measures to be taken in this area are evaluated under the guidance of the decisions of the Constitutional Court based on the national and international normative framework.
