Negative Reciprocity – a New Component of Public Order?

Unilateral restrictive measures of a number of states and countermeasures taken in response by Russia have had a significant impact on the case law in recent years. In particular, the category of public order has received a new vector of development aimed at protecting national interests. At the same time, the interaction between states within the framework of the mentioned measures is logical to consider from the point of view of such international legal principle as reciprocity (namely, its negative form). The author concludes that negative reciprocity constitutes a component of international and, accordingly, national public order, and respective reference to it in the reasoning part of court decisions (for instance, on refusal to enforce a foreign judgement due to the violation of public order) will add legal significance to such decisions.
