The antinomies of the idea of law in the institution of the version suit

The article deals with the formal, legal and substantive aspects of the concept of unjust enrichment, taking into account the formation of this institution in the domestic legal order, up to its current state, characterized by a gap in terms of version claims. There is a connection between the problem and the growing tendency in recent years to overcome the formal approach in judicial practice. It is shown that ethical elements prevail in the ideological content of the institution of the versions claim, which is currently not formally fixed, but is derived through a systematic and teleological judicial interpretation of the law. The possibility of using antinomies of the idea of law as a methodological tool for overcoming the gap in the regulation of situations corresponding to the classical model of actio de in rem verso is substantiated.
