Introduction. The article analyzes the legal certainty of the individual as the stability of the content of fundamental rights and freedoms in the context of democratic processes of reforming the current legislation and the Constitution of the Russian Federation. Theoretical analysis. The article notes that the need for stability of fundamental human rights and freedoms is in some contradiction with their dynamic, evolutionary nature. The author questions the possible and necessary limits of majority democratic will with regard to the transformation of the legal system, in general, and constitutional rights and freedoms, in particular. The article addresses some “points of tension” between democracy and the rule of law. Results. On the basis of the article, it is concluded that participation in the processes of democratic transformation of the legal system can be considered as a right to democracy and, in this understanding, it needs the search for a balance with other fundamental rights and freedoms. It is on the basis of this balance that the legal certainty of the individual must be ensured, combining, on the one hand, the stability of the substantive characteristics of fundamental rights and freedoms, and, on the other hand, the expansion of legal claims and the evolution of human rights.
