According to this theory, the typical legal system is founded upon a system of norms. The written laws form a part of a hierarchical system of norms, with each layer gaining authority from the previous. All the norms could be traced back through a chain of validity which is shown by a pyramid known as the Kelsen’s pyramid. At the top of this pyramid is the “Grundnorm,” namely the “Constitution” in our system.
