It will be argued, firstly, that there is a link between the legal validity of a norm and the rational justifiability of a requirement that judges should apply this norm, based on a normative conception of legal validity and the postulate that judges should act as rational persons; secondly, that rational justifiability of legal norms requires the construction of a legal system in a model of principles that differs from theories, e.g., of Kelsen, Hart, Dworkin and Alexy, which are not (...) fully adequate for a normative conception of law.

This article examines Robert Alexy's account of legal validity. It concludes that Alexy's account of legal validity lacks sufficient support given the author's methodological commitments. To reach that conclusion, it assesses the plausibility of simultaneously maintaining that the participant's perspective has conceptual privilege in the explanation of the nature of law, that legal discourse is a special case of general practical discourse, and that unjust considerations can be legally valid norms.

In the following paper is put in question the present-day dominant Italian ideology of the so called ‘new constitutionalism’, which considers human rights as an open-texture catalogue of claims which only the Constitutional Courts are entitled to interpret and implement. This ideology is considered as a tool for overcoming the traditional liberal rule of law in favor a of more and more developed rule of the courts.

The first part of this article contains an analysis of the concept of a right, which implies a rational structure of reasoning about rights, elaborated in the second part. In the third part both the concept of a right and reasoning about rights are connected with the theory of rational discourse. The author's thesis is that there exists an internal relation between the theory of rights and the theory of legal reasoning.
