This panel investigates how international law, formal state law and Indigenous and/or religious law interact and relate to one another by contrasting the historical example of 18th century maritime provinces in Canada with contemporary legal disputes from Bangladesh and Nicaragua to. The papers use ethnographic and legal historical methods to better understand those relationships.
How do norms get transformed and do new norms emerge from legal interactions? This panel looks at this question with three different case studies of actors weaving different legalities together: World Athletics’ engagement with the norm of gender equality; UNCLOS courts’ and tribunals’ consideration of broader norms of ocean governance; and the impact of corporate social responsibility norms on WTO law.
Almost seventy years after Philip Jessup coined the term “transnational law” as “all law which regulates actions or events that transcend national frontiers…both public and private international law”, the public-private law dichotomy is still deeply entrenched in legal thought. This panel brings together scholars who have regularly transcended this dichotomy in their work to discuss how legal multiplicity is impacting on our understanding of transnational law today.
How are online platforms that are used by billions of users around the world regulated? This panel looks at how platform economies such as Facebook or AirBnB are regulated and how they relate with and connect the different legalities they come into contact with. Does this challenge traditional understandings of law?
When faced with multiple legalities, how do we know what “the law” is, and how is this notion formed by different actors coming at this question from different vantage points? This panel investigates this question through different case studies, ranging from the post-colonial state of Papua New Guinea to Northern Colombia and China’s Belt and Road Initiative.
Informal, “soft” law has often been investigated through the lens of network authority. This panel contrasts two such perspectives from transnational law – private transnational legal regimes in the field of corporate social responsibility and the transition from and connections between informal and formal law in the field of global financial governance – with a theoretical approach that emphasizes the importance of connectivity norms for the global legal order.
The Conference on Multiple Legalities is organized as part of the interdisciplinary research group “Overlapping Spheres of Authority and Interface Conflicts in the Global Order”. Three research groups present their main insights from this multi-year collaborative endeavor in conversation with Jeffrey L. Dunoff. Some research results can be found in a Global Constitutionalism Special Issue.
How does multiplicity in law beyond (and within) the state affect our understanding of the nature of law? In this discussion, international law scholar Sarah Nouwen engages in a conversation with legal philosophers Brian Z. Tamanaha and Christoph Möllers to take stock of the debate and its implications for theories of law.
Formal legal rules do not appear out of thin air. Rather, their emergence is conditioned by frameworks that are invisible to the formalist perspective. This panel looks at how formal law is driven by an array of less visible factors: data, algorithms, and broader “background rules”.
How do different legal orders interact vertically? Is this interaction marked by conflict and contestation, or by compromise and collaboration? This panel looks at three different such interactions: between domestic courts and the Inter-American Court of Human Rights; between regional human rights courts and United Nations Treaty Bodies; and between Swiss domestic law and the lex sportiva.
