The case law of the European Court of Human Rights, as the judicial authority of the Council of Europe, influences the legal systems in the individual Member States. It is reflected in various branches of the national legal system adopted in the Council of Europe Member States, not only in the substantive provisions of constitutional law. This European ‘case law’ system constitutes a certain monolithic legal system founded on the categories of constitutional law, for instance in the areas of division of power, rule of law, liability of public officials and authorities, independence of the judiciary, administrative law including procedural relations, criminal law classical principles, the organization of the judiciary and implementation of specific procedural judicial principles such as equality of arms, equal standing of the parties and the right to legal assistance. It also penetrates the categories of private law –for instance, the gradual development of case law relating to the concept of privacy, freedom of thought and protection of the family. The binding force of the Council of Europe system under constitutional law and the influence of its contents on the individual legal systems justify the conclusion that the Council of Europe system is a phenomenon in the domain of international organizations.
