New forms of law and its creation, new modes of adjudication and dispute settlement, as well as new enforcement mechanisms in the transnational constellation challenge traditional understandings of law and corresponding legal theory. Inspired by critical engagements with the notion of the force of law, the project aims at developing a concept of a transnational force of law that addresses these challenges. To this end, it combines a comprehensive interest in legal theory and a legal philosophy with empirical research in three areas of transnational law — lex digitalis, lex financiaria and lex agraria.
