Declaratory theory is propounded on the belief that judges' decisions never make law, rather they only constitute evidence of what the law is. However, this view is no longer accepted. There are three reasons for the persistence of the declaratory theory. In the first place, it appealed in the separation of powers. Secondly, it concealed the fact that judge-made law is retrospective in its effect and finally, when the judges confronted with a new, unusual, or different point, they tend to present as if the answer is provided by the common law.
