Pursuant to Article 5 of the Constitution of the Republic of Poland, the Polish State is obliged, among other things, to safeguard security for its citizens. Therefore, the public authorities are required to undertake actions aimed at keeping the state of non-threat, allowing the citizens to pursue their interests. A question arises about the effect of failure to perform these obligations. This paper seeks to assess the effect of failure to safeguard security in the civil-law sphere. In particular, the paper discusses the concept of security, delineates the circle of entities burdened with security obligations and indicates the legal regime and conditions for liability for damages for failure to safeguard security. The article also provides an analysis of admissibility of approaching the sense of security as a personal right.
