United Nations Security Council and International Criminal Tribunal for the Former Yugoslavia

After World War I, it is seen that states attempted to establish organizations to act together in the field of international law. Organizations can act only if states transfer some of their rights through their articles of association. Due to the limited authority delegated to the League of Nations, which was the first example in international law, it caused limited movement and accelerated its dissolution. As for the United Nations, which was established after World War II, the limits of the rights that states waived and transferred could not be determined exactly by looking at the content of the founding agreement. For this reason, very different opinions have emerged in the legal evaluation of the establishment of the court established by the international organization body, which claims to have the authority to try individuals of international criminal nature. The main subject of the thesis is to examine how appropriate the judgments made by a court of uncertain legal nature will be. However, in order to understand the issue, the subject started from the organization established after World War I and the establishment, purpose, duties and powers of the United Nations were examined in the first chapter. In the second part, the previously established international courts were examined and the establishment process, structure, duty and authority of the International Criminal Court for Yugoslavia, established by the Security Council, and the nature of the decisions it gave were examined together with the trials in the courts.
