In this contribution I provide an interpretation of Stone Sweet’s and Ryan’s cosmopolitan legal order in conjunction with a certain reconstruction of the Kantian cosmopolitan rationale. Accordingly, I draw attention to the connection between the notion of a general (cosmopolitan) will in Kant’s reinterpretation of Rousseau and the role of the European Court of Human Rights (ECtHR) as an ‘interpreter’ of such will. I conclude by suggesting that the opportunity of extending the CLO also accounts for a variety of other poliarchical regimes that, taken as a whole, illustrate the landscapes of contemporary global constitutionalism.

In A Cosmopolitan Legal Order, Stone Sweet and Ryan suggest that ‘from the standpoint of global law, we see that the [European Court of Human Rights] has taken its place in a pluralist, rights-based international order, as one trustee of this global order’. This article is a preliminary attempt to evaluate signs of movement toward global rights review. A multi-level charter of rights exists in the network of international and regional human rights treaties and in national constitutions. An incipient structure of global rights review exists in the form of the regional human rights courts, which see themselves as trustees of the larger global human rights system. Judicial dialogue among the regional courts allows for informal, decentralized coordination among them. The European Court of Human Rights serves as a point of reference for the African and Inter-American systems, though these also cite each other. Transregional judicial dialogue establishes a rudimentary, informal and decentralized mechanism of coordination among bodies that exercise a review function in the multi-level system of international human rights.
