Pigolkin. Conclusions: 1) legal relations – a type of social relations characterized by general and special (essential) features; 2) legal relations (according to N. Wiener – "content obtained from the outside world" - primary, and legal regulators, according to N.

Hegel – the "stage of emanation") of modern international law, the author recognized international treaties developed in accordance with general (fundamental) principles of law, based on the consensus of subjects of international legal relations sharing the paradigm of a multipolar world.
