This paper defends a position that parts ways with the positivist view of legal certainty and reasonableness. I start out with a reconstruction of this view and move on to argue that an adequate analysis of certainty and reasonableness calls for an alternative approach, one based on the acknowledgement that argumentation is key to determining the contents, structure, and boundaries of a legal system. Here I claim that by endorsing a dialec-tical notion of rationality this alternative account espouses an ambitious (...) approach to rea-soning in law and conceives of the theory of legal argumentation as the vantage point from which to analyze legal systems and tackle the main problems connected with their existence. Next, I look at what this alternative approach does for the way we should go about treating certainty and reasonableness, considered singularly as well as in their recip-rocal relationship. I conclude on this basis that when argumentation receives its due emphasis in law we have to redefine certainty and reasonableness and recast their connection as non-conflictive. (shrink)

Precedent is a central feature of legal practice, requiring courts to follow decisions reached in earlier cases, thereby transforming the decisions in individual cases into a source of law. This article examines two major questions associated with precedent: (a) how to characterise the way that precedent operates as a source of law; and (b) how to justify the requirement that courts follow earlier decisions regardless of the merits of those decisions. Precedents are often thought to create general legal rules, but (...) it is controversial whether this is the best way to understand their role in legal reasoning. Equally, it is unclear that the most common justifications for precedent unequivocally vindicate the practice. (shrink)

This paper deals with the question of how norms are to be conceived of in order to understand their role as guidelines for human action within various normative orders, particularly in the context of law on the one hand and conventional morality on the other. After some brief remarks on the history of the term “norm,” the author outlines the most significant general features of actually existing social norms, including legal and conventional norms, from which he arrives at two basic (...) requirements on an appropriate conception of such norms: the actuality and the normativity requirements. On this basis, he enters into a critical discussion of Kelsen's highly influential view of norms, arguing that this view is doomed to failure. In the last part of the paper, the author scrutinizes the more promising “practice theory of norms” by H.L.A. Hart, which, in his view, also suffers from some shortcomings, but may be modified in a way that leads to a conception of social norms providing us with a plausible explication of their actual existence and their normative force.
