The Binding Origin of Extra-Contractual Rules of Human Rights

Undoubtedly, human rights are among the achievements of modern international law. One of the most controversial topics in this field is the binding origin of its rules. It is obvious that those human rights rules that have a contractual origin are accepted by the signatories. But the problem starts precisely from the fact that some subjects of international law (international organizations) are not members of human rights treaties, except in exceptional cases such as the European Union, and in case of violation of the mentioned provisions, they will not be held responsible. To solve this problem, it is necessary to find a non-contractual source  which can cover all subjects of international law, especially international organizations.
