The author's thesis is that there is a conceptually necessary connection between law and morality which means legal positivism must fail as a comprehensive theory. The substantiation of this thesis takes place within a conceptual framework which shows that there are at least 64 theses to be distinguished, concerning the relationship of law and morality. The basis for the author's argument in favour of a necessary connection, is formed by the thesis that individual legal norms and decisions as well as (...) whole legal systems necessarily make a claim to correctness. The explication of this claim within the frame of discourse theory shows that the law has a conceptually necessary, ideal dimension, which connects law with a procedural, universalistic morality.

The author revisits H. L. A. Hart's theory of positive law and argues for a major qualification to the thesis of the separation of law and morality based on a concept of systemic legitimacy derived from the social theory of Jurgen Habermas. He argues that standards for assessing the degree of systemic legitimacy in modern legal systems can develop through reflective exercise of “critical legality,” a concept coined to parallel Hart's “critical morality,” and an expanded understanding of the “external” and (...) “internal” perspectives on legal systems. Following Habermas, he argues that modern positive law must retain systemic legitimacy. After suggesting criteria for measuring systemic legitimacy, the author concludes that the concept provides a useful approach to contemporary problems of “lawless” regimes and “law's imperialism.”.
