Transnational Legitimacy in a Globalising World: How the European Union Rescues its States

Abstract: This article addresses claims regarding the limited legitimacy of international institutions. It argues that the two original appointed supranational institutions of the European Union play a crucial, if systematically underestimated, role not merely in providing legitimacy for the Union itself, but also in shoring up that of its constituent member states. We illustrate that supranationalism enhances national legitimacy in functional, political and administrative terms. It does so by helping member states produce outputs they otherwise could not (particularly by enabling them to deal with transboundary policy problems they would struggle to confront if acting in isolation) and by embedding within national political and administrative systems legally enforceable obligations to respect the interests of actors whose voice is excluded or muffled (de jure or de facto) within purely national political processes. The article contends that the claims to legitimacy made by the EU and its member states are of distinctive character but interdependent and mutually reinforcing.
