In the enquiry into the import and function of the basic norm in Hans Kelsen's legal theory, the interpretations of special interest are those dealing with the notion of the basic norm as the ‘logico-transcendental’ condition for cognition in legal science, or with the relation of Kelsen's juridico-scientific method to Kant's practice philosophy. Two thinkers in particular have written along these lines, Norbert Leser and Ralf Dreier, respectively. This chapter begins by describing the positions taken up by the two authors. (...) It then asks, whether in terms of Leser's thesis, it is in fact possible to maintain the notion of the transcendental character of the basic norm. It then turns to Dreier's suggested reinterpretation of the basic norm by appeal to the law of reason, examining the suggestion from the point of view of Kant's philosophy. (shrink)
