For a long time, customary law dictated human activities by reflecting the conduct of people towards one another. Under customary law, rules spontaneously emerged and evolved to settle a dispute between people. These spontaneously born rules are voluntarily followed by the parties involved in the dispute and are more likely to be satisfying to the parties than a rule imposed on them by a authoritative body. The customary law was the process that lead to the discovery of natural law. Natural law is the indisputable standard to which laws must be consistent in order to be legitimate. In other words, we can say that natural law is the body of rules of right conduct and justice common to all people. By comparison, common law is a system by which a law comes to pass based on some legal precedent.
