The material turn has come late to law, though it has shaped works in anthropology, history, philosophy, and science and technology studies. It is concerned with the roles that non-human objects play in human actions and relationships. We employ the term 'legal materiality' to emphasise that legality is not a determined status, but that legal power varies depending on law's specific techniques of representation, media and institutional settings. Such a materialist approach asks how material elements in legal processes, such as images or software, influence the persuasiveness of evidence or classify certain individuals into target populations. Moreover, a new materialist approach towards law explores the multiple ways in which law acts on different matters across society. Law becomes material by exerting tangible and corporeal effects, such as on the bodies of women, the ill, prisoners or refugees. Such a legal materialist approach entails the view that a full picture of legality is not to be found in legal doctrines and their textual interpretation, but across different objects in society. This calls for supplementing existing approaches to law. For example, a legal materialist approach provides a more insightful analysis of the 2017 executive order issued by the American president that sought to temporarily suspend travel of individuals from seven Muslim-majority countries. Whereas a doctrinal approach addresses the constitutional basis of the order and its interpretation by the judiciary, the lens of legal materiality places this text in the context of its material genesis, mediation and tangible effects: from the placing of words in the order, to the inscription of the president's signature on paper, to its digital dissemination through social media platforms, to biopolitical effects on targeted individual bodies and their ability to move across space. A legal materialist lens would expose the concrete genesis, media shifts, and the differential effects on targeted groups of population of the legal instrument in full. Understanding the meaning and effects of these steps requires critical analysis, drawing upon expertise from the humanities and interpretive social sciences, as well as a sensibility for the specific properties of legal matters: paper, social media platforms, border spaces, and human bodies. To facilitate such interdisciplinary analysis of law's social and cultural effects, we will create a new network of scholars working on legal materiality. The central aim of the network is to build a novel platform for exploring the relationships between legal processes and human and non-human entities. The network will bring people from different traditions in the arts and humanities (including law, history, literature, anthropology, media and science studies) who are working on aspects of law and new materialisms, together with artists and policy actors, to develop novel research approaches. The network will address a range of questions, such as: how do texts and interpretive practices relate to objects, bodies and spaces?; What are the implications of actor network theory and other new materialist approaches for legal scholarship? What are their limitations?; What resources can be drawn from the humanities, the interpretive social sciences and artistic communities to better understand the effects of new technological developments in law? Activities comprise four events, beginning with a cross-disciplinary event and culminating with an international conference. We will foster deliberative public engagement and exchange in the second public event that will bring into conversation academics, artists and activists who have worked on law's material forces, particularly digital surveillance and privacy. Through open exchange and dissemination, network participants will shape research agendas on law's effects within and beyond the academy. It will lay the groundwork for a new approach to law.
