The study is based on the theoretical works of domestic specialists who have studied the A. F. Koni’s legacy. Study results. The moral concepts of A. F. Koni were formulated in the Constitution of the Russian Federation, wherein the fundamental tenets of administration of justice are enumerated: independence, irremovability, inviolability of judges, and openness of court proceedings.

Koni were mirrored in the Law of the Russian Federation No. 3132-1 on the Status of Judges in the Russian Federation dated 26 June 1992. The Code of Judicial Ethics adopted in 2012 gains particular importance in the context of the analysis of A. F. Koni’s legacy.
