Abstract
What happens when collectivity and law intersect? Lisa Hahn and Markus Hasl outline the state of research on this question and add new answers offered by this special issue. On the one hand, the search for interdisciplinary encounters shows that law is both means and object of collective legal struggles. In doing so, collectives shape law. On the other hand, law (re)produces collectives through categorization and personalization; it juridifies. In doing so, it oscillates between productivity and destructiveness. The authors conclude that to advance the productive potential of collectivity and better regulate its risks, theoretical and doctrinal innovations are needed.
