The dissertation reveals the theoretical and legal foundations and the public legal instruments of public administration in the natural gas market in Ukraine, based on the study and generalization of conceptual principles, normative sources of Ukraine and European Union legislation, and empirical data. A comprehensive scientific analysis of the legal nature of informational legal relations in the medical field of Ukraine has been conducted in the dissertation. It has been proven that such legal relations arise in the process of creating, accumulating, transmitting, using, and protecting medical data, which are sensitive in nature and require a specific legal regime. The interdisciplinary nature of the studied phenomenon has been characterized, as it combines norms of information, medical, civil, and administrative law. The specific features of the object of these legal relations – medical information – have been substantiated, including diagnoses, treatment methods, examination results, prognoses, and other data concerning a person’s state of health. The circle of subjects has been outlined, including patients, medical workers, healthcare institutions, public authorities, local self-government bodies, and civil society organizations. It has been established that the legal content of these relations includes the rights to access, informed consent, confidentiality, as well as obligations regarding the preservation of medical secrecy. The digital specifics of implementing these rights and duties have been disclosed, which determines the need to update regulatory frameworks. In the course of the study, the current regulatory and legal framework that ensures the legal regulation of informational relations in the field of healthcare has been systematized. It has been found that the key sources are the Constitution of Ukraine, the laws “On Information,” “On the Protection of Personal Data,” “Fundamentals of Ukrainian Legislation on Health Care,” and relevant codes. International instruments defining standards for the circulation of medical information – including the Convention on Human Rights and Biomedicine, EU regulations, and the application of GDPR – have been analyzed. The essence of informed consent as a fundamental element of the legal justification for processing medical data has been determined. The role of public authorities in ensuring legality, transparency, and accountability in the circulation of personalized medical information has been substantiated. An original definition of informational legal relations in the medical field as a systemic legal phenomenon operating in the digital environment has been formulated. Proposals for improving legislation have been developed, taking into
account current technologies and the need to protect human rights in the healthcare sector. The principles of informational legal relations in the medical field have been defined as the normative foundation that regulates the circulation of personalized health information. Their nature is revealed as a combination of legal norms, ethical standards, and technical regulations that ensure balanced interaction among
participants in the medical information system. The dominant role of the principle of legality has been highlighted, which requires a clear legal basis for any form of data processing. It is noted that the principle of voluntary consent of the patient is key to the legitimacy of such actions, while the principle of proportionality limits excessive data collection and the duration of data retention. The principle of accuracy obliges to
ensure the reliability and correspondence of the data to the actual state of health. Confidentiality is viewed as an absolute guarantee against disclosure without legal grounds. The principle of limited access allows only those who provide medical care to process such information. The content of each principle is specified through the analysis of legislative acts, cybersecurity policies, and technical protocols in the healthcare sector. Emphasis is placed on transparency of interaction as a tool for ensuring public accountability of entities handling sensitive information. It is defined that all principles operate within
the framework of digital infrastructure, forming a stable legal structure in the electronic environment. The significance of technological adaptation as a principle ensuring interoperability, security, and innovative development of medical platforms is highlighted.
