The good implementation of the constitutional principle of equality is a certain criterion for evaluating the legislative regulation of both the rights and freedoms enshrined directly in the Constitution of the Russian Federation and the rights acquired based on the law. The paper separately considers one of the integral components of this principle that is gender equality in the context of the modern implementation of the formation of representative bodies of state power both in the Russian Federation and in several foreign countries. The study of gender equality allowed assuming the heterogeneity of its legislative consolidation (from mandatory compliance in the Scandinavian countries, to complete rejection in the Muslim countries). The author's point of view about the development of gender equality not as a defense of special rights of a particular category, but as a recognition of the equality of personal value without attributes of gender, race, and age, is substantiated.
