On the theory of interpretation
The legal system is not a system of co-ordinate norms, found at one and the same level. Rather, it is a hierarchical structure of superordinate and subordinate legal norms, whose reciprocal relations are illuminated by the structural analysis undertaken by the Pure Theory of Law. The enquiry into the hierarchical structure of the legal system has significant consequences for the problem of interpretation. Interpretation is an intellectual activity accompanying the law-creating process as it moves from a higher level of the hierarchical structure to the lower level governed by this higher level. In the standard case, that of interpreting statutes, the question to be answered is how, in applying the general norm (the statute) to a concrete material fact, one is to arrive at a corresponding individual norm (a judicial decision or an administrative act).
