In the Republic of Serbia, as in other jurisdictions, there is no unanimously accepted definition of the privacy, either in legal doctrine or in legislative instruments. The national constitutions, including the Serbian one, usually protect the privacy of individuals by referring to: (1) the inviolability of home; (2) the confidentiality of letters and other means of communication; and (3) the protection of personal data.
