Based on Article 34 European Convention on Human Rights, individual applications must be directed against one of the Convention States. Originally ‘horizontal’ cases therefore must be ‘verticalised’ in order to be admissible. This means that a private actor who had first brought a procedure against another private actor before the domestic courts, must complain about State (in)action in his application to the European Court of Human Rights. [---] The wide variety of verticalized cases is also reflected in the Court’s approach to them, as is the second main topic that the present article explores.
