In order to strengthen the logic of the rule of law in the international system, it is necessary for States, international organizations and other entities to have an exactly understanding of the process of accepting and identification of legal rules. Except in the case of treaties, in the framework of which the provisions of international law require the express consent of the member states, other main sources of international law, including custom and general principles of law, should be recognized by the international community, which is currently the judicial decisions and doctrine are considered to be one of the most important tools for determining these rules in international law.Absolutely, knowing these tools will be effective in improving understanding and increasing the efficiency of international law regulations.
