The Applicant was arrested for being a member of an armed terrorist organization and is in detention in the Penitentiary Institution. It was conveyed to the penitentiary institutions across the country through the public prosecutor's offices following the Circular dated October 10, 2016 issued by the General Directorate of Prisons and Detention Houses (the “Circular”), that all letters, faxes and petitions must be scanned and recorded in UYAP, with the exception of the letters and faxes in closed envelopes, given by those convicted or detained in penitentiary institutions to the official authorities or to their lawyers for their defense. Penitentiary institutions have accordingly started implementations in accordance with the content of the Circular. The letters sent and received by the Applicant were recorded in UYAP within the scope of the aforementioned Circular.

Applicant applied to the Court of Execution to terminate the practice of recording the letters he sent and received in UYAP and to have the records deleted. In his petition, Applicant emphasized in his petition that there was no legal basis for the permanent recording of the letters he received and sent to the system, and that his requests for the termination of this practice and the deletion of the records were not answered by the Penitentiary Institution, and argued that his right to respect for private life and the presumption of innocence have been violated.

Court of Execution emphasized that as per Article 68/2 of the Law No. 5275 on the Execution of Penalties and Security Measures (the “Law”), it is regulated that the letters, faxes and telegrams sent or received by those convicted would be inspected by the letter reading commission, and in the absence of a commission, by the highest chief of the institution.

Referring to its Kemal Karanfil decision (Kemal Karanfil, App. No: 2017/24776, 24.05.2018, § 48), the Constitutional Court stated that, with some exceptions, recording of the correspondence, which provide the Applicant's communication with the outside world, to UYAP after being audited by the institution's administration and opening and reading letters containing personal information and keeping them in the system constitute interference with the applicant's private life and correspondence.

It should be determined whether the limitation complies with the criteria of being foreseen by the law, having a legitimate aim, not being contrary to the requirements of the democratic social order and the principle of proportionality, all stipulated under Article 13 of the Constitution and correspond to the present application. In this context, it should first be examined whether there is a legal basis for the intervention in the present application.

It has been emphasized that the existence of the laws on the restriction of fundamental rights and freedoms in form is not sufficient, and the criterion of legality also requires a material content, and at this point, the essence of the law gains importance. In terms of the present application, it has been stated that the determination of the rules regulating In terms of the present application, it has been mentioned that the entry of information into the relevant system should be conditional on carrying out the legitimate purposes that form the basis of the intervention, and the relevant legal regulations should include clear and detailed provisions on which information can be recorded, which authorities they can be forwarded to, under what conditions such a communication is possible, and the procedure to be followed while forwarding the information to the relevant authorities. It has been emphasized that the regulation regarding the aforementioned system should provide the citizens with the opportunity to make sufficient foresight in terms of the manner and scope of the exercise of the discretionary authority granted to the competent authorities in collecting, recording and sharing with the relevant authorities or otherwise using the information.

It has been stated that the law or the legislation based on the relevant law should determine the scope of the systematic recording of correspondence as well as the principles regarding the retention of letters, content and private information and personal data included therein. In addition, the relevant legislation should also include clear and detailed rules that will ensure that the addressees have sufficient security against excess of authority and arbitrariness regarding the retention period of the prisoners' correspondence, the access of third parties to these correspondences, the use and destruction of the data contained, and the secrecy of the data.


In the present application, it was regulated by the Circular that all faxes and correspondence should be scanned and recorded in UYAP, with the exception of letters and faxes in closed envelopes, given by those convicted or detained to official authorities or to their lawyers for their defense. This arrangement allows the prisoner's correspondence, which is not unsafe, which include personal information, and which is not related to judicial processes, to be kept in UYAP. This acceptance results in diverging from the procedure determined by the legislation for the letters in the physical environment based on whether or not they are unsafe. In addition, since there is no clear regulation on how long the prisoner's correspondence will be kept in the system, under what conditions they will be made available to third parties for access and use, with which authorities they can be shared by the penitentiary institution, and how personal data and privacy will be protected, it has been determined that there is unclarity in terms of the foregoing issues. Accordingly, it was unanimously ruled that the Applicant's right to respect for private life in terms of privacy and requesting the protection of personal data and the right to freedom of communication guaranteed in Articles 20 and 22 of the Constitution, have been violated.
