Public International Law governs the conduct of states and international organisations such as the United Nations (UN)1, and the relations between them. Areas of public international law include air law, diplomatic relations, the law of armed conflict, environmental law and trade law.2 Therefore, the International Rule of Law is within the context of Public International Law since the rule of law is generally supported at the international level. The United Nations is an international organization consisting currently of 193 Member States. It was founded in 1945 after the Second World War by 51 countries committed to maintaining international peace and security, developing friendly relations among nations and promoting social progress, better living standards and human rights.3 Due to its international character and the powers vested in the United Nations Charter, it can take action on a wide range of issues,4 and provide a forum for the Member States to express their views, through the General Assembly, the Security Council, the Economic and Social Council and other bodies and committees.5 The Member States of the United Nations are in the practice of customary international law and also agreements which are entered to through State treaties6. Treaties7 are the main sources of international law. Among other things, international law also deals with other international issues like arms control, human rights, use of the oceans, terrorism, refugees, and much more, and within each of these fields of international law the number of rules, principles, and concepts continue to increase as time goes on8. .
International Law is, therefore, important to ensure the peaceful development of human rights, communications, maintenance of international peace and security, use of sea and airspace, trade and development aid including other essential factors which includes the peaceful settlement of disputes between Member States.
