This article attempts to actualize and specify theoretical understanding of rule of law in the field of public management in modern reality. Pandemic, geopolitical tensions, natural disasters, critical trends, sanction and other turbulent hazardous social phenomena — all those issues shape new approaches to relationships in the field of public management, their legal regulation and legal application, but moreover — they somehow transform the properties and coordinates of rule of law in this sphere of public activities. The author concludes that the rule of law is not just a specific normative identity, but rather it is a wide legal space where public administration rules freely in accordance with its legal status and is able to take regulatory measures as necessary — including unordinary ones. The administration might as well make mistakes or change vectors, but it is always obliged to act with initiative and haste in accordance with the real situation and based on logic, rationale, performance and efficiency for the sake of achieving social goals — while staying in the national legal field to the extent of the Constitution and international legal norms and principles. Those are the defining points that support the modern scale of measuring the rule of law. Contemporary and well-reasoned specified legal contents of the rule-of-law principle is intended to eliminate the deficiency of legal order in administrative activities through the scope of universally accepted standards — justice, certainty and resilience in social relationships that ensure well-balanced interaction between the state, personality and society.
