Abstract

In this article, I take up two arguments in favor of the discursive model of legal argumentation: the claim to correctness argument and the dual nature thesis. The argument of correctness implies the dual nature thesis, and the dual nature thesis implies a nonpositivistic concept of law. The nonpositivistic concept of law comprises five ideas. One of them is the special case thesis. The special case thesis says that positivistic elements, that is, statutes, precedents, and prevailing doctrines, are necessary for law in order to achieve legal certainty. Without this, law would not be as perfect as it could possibly be. But it says, at the same time, that this alone would not be enough to fulfill the claim to correctness. The claim to correctness refers not only to the real dimension of law, defined by statutes, precedents, and prevailing doctrines, but also to its ideal dimension, defined, first and foremost, by justice. The special case thesis is my oldest thesis. It has remained an essential element of my system over the years. Its connection with four other theses—the Radbruch formula, the human rights thesis, the idea of deliberative democracy, and principles theory—does not change this at all. On the contrary, this connection has lent greater strength to the special case thesis.
