This article analyzes the interactions between norms formally stemming from different orders and regimes so as to demonstrate how and to what extent the legal spaces composing the transnational legal sphere are intertwined. Furthermore, it addresses the consequences of the intertwinement and suggests a fresh approach to the traditional concept of legal orders: it stresses a norm-centered rather than system-centered understanding of the transnational legal sphere. It argues for a norm-based strategy in order to understand the phenomenon of intertwinement, analytically deducing the relationship of the legal orders from the relationship of the legal norms.
