Abstract

Abstract. It is commonplace that economic globalization poses new challenges to legal theory. But instead of responding to these challenges, legal scholars often get caught up in heated yet purely abstract discussions of positivist and legal pluralist conceptions of the law. Meanwhile, economics-based theories such as "Law and Social Norms" have much less difficulty in analysing the newly arising forms of private and hybrid "governance without government" from a functional perspective. While legal theory has much to learn from these approaches, we argue that they fail in one crucial point: They cannot uphold the analytical distinction between law and non-law. The reasons for this shortcoming are theory-immanent in that the economic theories' focus on efficiency and their actor-based perspective are necessarily blind to "law's own rationality." We therefore propose to further develop those functional approaches to the study of global governance by complementing them with elements from Niklas Luhmann's systems theory of law. This will provide us with a conceptual framework for analyzing the workings of global governance regimes without ignoring their potential for "legalisation" and "constitutionalisation." As we will show in three concrete examples (Corporate Social Responsibility, lex mercatoria , and internet regulation) we can thus describe the evolution of new forms of legal regulation beyond the nation-state. This will also allow us to draw some preliminary conclusions on the role of law in the context of globalization and, at the same time, show the direction for further empirical research.
