In this paper the thesis is argued that there is no need for a special legal logic to deal with the defeasibility of legal arguments. An important argument for this thesis is that legal judgements ask for a complete justification and that such a complete justification requires a deductively valid argument.

In this contribution I argue that Brouwer’s legal positivism suffers from an internal tension that is not easily solved. This tension stems from the combination of two strands in Brouwer’s thought. The first is that Brouwer wants to stick to the legal positivist view that the law is fixed by convention. The second is that there can be exceptions to the application of legal rules, based on legal principles. The combination of these two strands is, I argue, problematic, because the (...) conventional basis for legal principles will usually be lacking in hard cases. One may then argue, as Brouwer does, that where conventions are lacking there is no law and the judge is not bound by the law. But then exceptions to rules are also allowed where there are no conventional principles to justify these exceptions. This contradicts Brouwer’s starting point that exceptions to the application of rules are possible on the basis of legal principles. (shrink)

This article is a comment on Carel Smith’s paper. Smith rightly argues that the study of law has a hermeneutic character. But his interpretation of legal hermeneutics includes the thesis that in hard cases there is no right or true legal decision. This seems to have negative implications for the scholarly character of the study of law: in hard cases any solution goes. This paper argues, against Smith, that the study of law defends right answers for hard cases. It is (...) also normative in another sense: legal answers, in easy cases as well as in hard cases, always presuppose a normative interpretation of the legal sources. This contributes to the differences of opinion under lawyers. But it is no obstacle to the scholarly character of the study of law, as long as a rational debate about these legal answers and the underlying values and principles is possible. Smith’s rejection of the right answer thesis, however, prevents the possibility of such a rational debate. (shrink)
