("Can Justice be Transnationalised?"), with Stefan Gosepath, in: Peter Masuch et al. (eds.): Grundlagen und Herausforderungen des Sozialstaats - Denkschrift 60 Jahre Bundessozialgericht (Festschrift 60th anniversary of the Federal Social Court), Berlin: Erich Schmidt Verlag 2014, pp. 499-515.
This chapter is an introduction to the global justice debate in political theory and philosophy aimed especially at theory-interested legal scholars and political scientists. It surveys main positions that have arisen in this debate over the last three decades and explains how their core commitments and starting points (ethical particularism vs. universalism, relational vs. non-relational concepts of justice, practice-dependence vs. practice-independence) lead to different answers to the question to which extent social justice can and should be transnationalised. The final part asks in what measure these theoretical differences really translate into different practical policy prescriptions. It proposes a layer model - global, regional, domestic - for the effective protection of socio-economic rights of potentially increasing demandingness, and suggests that proponents of most main positions, cosmopolitans and non-, should be able to agree on this model, though of course not on all details as to how to fill it out. Even if they should not, measuring these theories against the model has at least the virtue of making it easier to pin down where exactly they disagree in practical terms.
