The Legitimacy of State’s Evaluation in Implementation of United Nations Security Council

In UNs history, the Legality of Security Council Resolutions, in many cases, is challenged. Generally these challenges take by states that affected Security Councils decisions. With notice that states are the representative for implementation of SCR's, they intervene their determination and interpretation in the way that implement SC decisions. In some cases domestic and regional courts evaluate the state's action in implementation SCRs. Although these cases couldn’t provide direct review on Resolutions but affected in the way of implementation. Evaluation by states is probable and arises some concerns about decrease effectiveness of SC in maintenance of international peace and security.
