Migration crisis, food crisis, economic crisis the most alarming tendencies in our contemporary world are related to the transnational social question. But what role does transnational law play in this context: Does it exacerbate the asymmetries by shielding the rich and exploiting the poor? Or is the emerging regime of international social human rights a promising candidate for countering the crisis of world society?This book scrutinises both the potentials and the boundaries of de-coupling the notion of "social rights" from the nation-state and of transferring it to the transnational sphere. By drawing on a critical theory of transnational law, it provides in-depth analyses of the different sites where the struggle for social rights is at stake, such as the emerging transnational food regime, the ILO, international environmental law and the accountability of private actors. It reveals enforcement structures, discusses judicial doctrine and relates these aspects to the social and political struggles which surround the transnationalisation of social rights.
