This article presents the author's position regarding such a basis for the emergence of civil rights and obligations as “harm to another person.” The novelty of the study lies in the comprehensive analysis of legally significant circumstances, which together form the actual basis of obligations from harm. In particular, it is proposed to consider harm not as a single legal fact, but as a set of independent elements — actual circumstances, each of which has an independent legal significance. The study brings novelty to the theoretical understanding of the composition of a tort obligation and offers a more flexible and comprehensive model for its legal assessment.
