The publication „Legal Issues“ publishes a comprehensive article by LFMI‘s Junior Policy Analyst Adolfas Mackonis. The article presents a conceptual analysis of the notion of public interest. It claims that public interest cannot contradict the individual interests of the members of society and it has to accord to these interests. However, according to the Arrow theorem, public interest of this kind is impossible if one wants it to be fair and rational. Since it is impossible to satisfy all of the public interest requirements, the option that would satisfy most of them is the principle of inviolability of the person, which unfolds as the inviolability of life, liberty, and property. This would allow a coexistence of diversity of individual interests, without imposing on anybody any compulsory interest.
