The present study was conducted with the purpose of a legal review of the determination of the Security Committee on the development and progression of international law with an emphasis on international peace and security in international law. Given that the founders of the United Nations considered the Security Committee as the most important organ, It was necessary for the organization to provide the most authority to the Council, so they gave two kinds of performance to the Council: first, the peaceful determination of disagrees, which enabled the Council to investigate and recommend a conflict. A circumstance that threatens international concord and protection, and secondly, the Council's threats to peace and aggression (Chapter VII.) In other words, the main tasks of the Council are the implementation of the sixth and seventh chapters of the Charter. Many international organizations of internal affairs manage their structure in the form of a resolution endorsed by the members. Among these executive decisions, we can decide on the formation of special organs within the organization, the acceptance of new members, the transformation of affiliated entities, budget decisions, etc. The Council could also make binding decisions since all UN member states have agreed, in conformity with Article 25 of the Charter, to make judgments of the Security Committee in accordance with the Charter. Of course, the general impression is that the Council's binding decisions are taken only in cases of "threats to peace, violations of peace or threats to peace and acts of rape". But deciding whether such conditions have been fulfilled is under the mastery of the Security Committee under Article 39 of the Charter. And as soon as the Committee concludes that there is a threat to peace or other conditions, it may advise the parties concerned or what steps should be taken to sustain peace (Article 39 of the Charter). Make appropriate decisions. The results showed that the resolutions are of particular importance in terms of plurality and power, but due to their lack of precision, their position among international sources of law has been the source of doubt and wide-ranging questions.
