This project is against the background that the 'interfaces' between the two legal orders have been enriched by the subject matter extension of international law into domestic regulatory agendas, and by the increasing amenability of domestic judicial and non-judicial actors to international law. Its working hypothesis is that the greater permeation of international law into the domestic legal order may in turn reconstruct the 'face' of international law vis-à-vis national law. The project enhances cooperation between various (externally funded) research projects at the ACIL.
