ABSTRACT. Control on legality of the covert investigative actions by the law enforcement agencies is important for any democratic state in accessing the electronic communications identifying data. Article 15 of the Constitution of Georgia protects one of the most sensitive areas of human personal life - rights to personal and family privacy, personal space and privacy of communication, which is inviolable from any unjustified interference by the State and private individuals. Accordingly, the Constitution of Georgia guarantees the right to protection of the privacy of a person and establishes a formal, procedural precondition for the executive authority not to restrict these rights without judicial supervision. The right to inviolability of privacy may also be restricted in the democratic state for the attainment of the legitimate aims envisaged by the Constitution, but with the obligatory observance of the condition, that interference with the rights for achievement the goal shall be effected in a manner necessary and proportionate. The protection of this right becomes even more urgent when it comes to the processing of electronic communication identifying data by law enforcement agencies for the covert investigative goals. Law enforcement agencies are permitted by law to carry out operative and covert investigative activities, thereby there is the risk of their inappropriate use, so effective supervision of their activities significantly supports the protection of human rights from unjustified and ungrounded interference. Given the urgency of the issue, the paper deals with the scope of the powers of supervisory bodies in the conduct of covert investigative activities by law enforcement agencies in Georgia as well as the powers of the European Data Protection Council with regard to the control of personal data protection throughout the EU.
