CILJ 2025: Closing addresses

The Hersch Lauterpacht Memorial Lecture is an annual three-part lecture series given in Cambridge to commemorate the unique contribution to the development of international law of Sir Hersch Lauterpacht. These lectures are given annually by a person of eminence in the field of international law.We will come together to celebrate the life and scholarship of our colleague and friend, Professor Karen Knop (1960-2022). Karen, until her untimely passing, was the Cecil A Wright Chair at the University of Toronto’s Faculty of Law. A long-time friend of the Lauterpacht Centre, Karen was to have delivered the Centre’s 2025 Hersch Lauterpacht Memorial Lectures.The 2025 Lectures will take place on 13 and 14 March, over four special sessions, conversing with Karen’s extraordinary body of work across the history and theory of international law, gender and feminism studies, and private and foreign relations law. Four former HLM Lecturers will deliver these lectures in conversation with three discussants, all outstanding scholars mentored by Karen.Session IV Discussion and Q&A led by Professor Susan Marks Chair: Professor Antony AnghieProfessor Marks will lead the discussion of the three talks, teasing out cross-cutting themes and the enduring influence of Karen Knop’s scholarship across different fields of international law scholarship. Susan Marks is Professor of International Law at the LSE.

Hersch Lauterpacht Memorial Lectures 2025: Diversity and Self-Determination in International Law: Continuing Conversations with Karen KnopWe will come together to celebrate the life and scholarship of our colleague and friend, Professor Karen Knop (1960-2022). Karen, until her untimely passing, was the Cecil A Wright Chair at the University of Toronto’s Faculty of Law. A long-time friend of the Lauterpacht Centre, Karen was to have delivered the Centre’s 2025 Hersch Lauterpacht Memorial Lectures.Session III Private and Foreign Relations LawProfessor Anne Peters in conversation with Dr Roxana BanuChair: Professor Campbell McLachlanProfessor Peters’s talk, 'Populism, Foreign Relations Law, and global order and justice', will discuss populist foreign relations law, which was Karen Knop’s last project, at the university of Helsinki and as a Max Planck fellow. This talk will make the point that ongoing transformations of the concept of law itself, of legal procedures, and of legal substance cut across the ‘levels’ of governance. And neither identitarian rhetoric, nor trade wars, nor border-fences will bring back an inter-state, Westphalian (or ‘Eastfalian’) order. We are living in conditions of global law (and transnational) law. Populist heads of state both deploy and defy this law (concluding populist treaties or deals such as the German-Turkish refugee agreements; denouncing treaties such as ICSID or the Paris Agreement; using their war powers to escape domestic critique; raising tariffs to please their voter-base, and so on). At the same time, domestic, local and transnational actors (ranging from cities to courts to Indigenous peoples, or philanthro-capitalists) activate all kinds of law to resist populism. Such global lawfare destabilises world order but also has a transformative potential. New legal forms (especially informal agreements), new legal processes (such as public interest litigation before the ICJ) and new legal principles (such as One Health; Rectification/reparation; and the exposure of double standards) are responding to the big challenges for global order and justice: the cultural, the social, and the ecological challenge. Dr Banu’s talk, 'Foreign Affairs, Self-Determination and Private International Law', begins with the point that foreign affairs questions are often thought to lie at the very edge of private international law, perhaps in the leftover corners of the historical alignment between private and public international law. Similarly, in part on the assumption that private international law settles conflicts of laws between already established states, there wouldn’t appear to be any intuitive connection between nationalist or self-determination movements and the field of private international law.This talk will show that these assumptions are mistaken. By engaging with the historical development of the field from the mid-nineteenth century onwards, the talk will show that private international law has been deeply enmeshed in major geopolitical events generally, and in nationalist and self-determination movements, in particular. This enmeshment is neither accidental, nor exclusively modern. It is the inevitable result of some of private international law’s main analytical and conceptual building blocks. Anne Peters is Director at the Max Planck Institute for Comparative Public Law and International Law Heidelberg (Germany), and Professor at the universities of Heidelberg, Freie Universität Berlin and Basel (Switzerland). Roxana Banu is Associate Professor and Tutorial Fellow at the Faculty of Law and Lady Margaret Hall, University of Oxford.

It will then focus on the challenges that cultural and ideological pluralism poses to received ideas about the role of law in the government of domestic and international society. Dr Donaldson’s talk, ‘Gaze, Agency and International Society’, reads Karen Knop’s early work on self-determination as a repertoire of techniques for thinking collectivities and affiliations against and across states. The multiple and mobile perspectives she brought to bear, and the agency she glimpsed in disparate individuals and communities, pervaded much of her later work too, and remains open to, even generative of, renewed understandings of international society.Martti Koskenniemi is Professor Emeritus of International law at the University of Helsinki. Megan Donaldson is Associate Professor of International Law at University College London.

In the mare liberum, seafarers are protected by the age-old maritime duty to rescue anyone in distress at sea. This principle has also been codified in various treaties, including the 1974 Safety of Life at Sea (SOLAS) Convention. This convention was adopted in response to the Titanic disaster and mainly focuses on safety on board of commercial ships. But the most vulnerable people at sea nowadays clearly are irregular migrants, sailing by rubber boats rather than cruise ships. Formally, these migrants are also protected by the non-refoulement principle under refugee and human rights law. Yet in practice, they are subject to a politics of protection which operates through an intermeshing of different legal regimes. Moreover, the rubber boats play a crucial role in this politics of protection, and ultimately preclude the irregular migrants from the protection of the non-refoulement principle. Through the case of the rubber boat, as a transnational legal encounter of people, rules and objects, I investigate the uneven geographies and temporalities of international law as an everyday practice. Moreover, by paying critical attention to how objects participate in actualising certain sets of relations and potentials over others, the concept of transnational legal encounters enables us to critically re-think the production of meanings, legalities and politics, layering complexities to law’s work in and to the world.Tanja Aalberts is Professor of Law and Politics at the department of Transnational Legal Studies, VU Amsterdam. She is the author of 'Constructing Sovereignty between Politics and Law' (Routledge, 2012), co-author of 'The Changing Practices of International Law' (CUP, 2018) and co-edited 'The Power of Legality. Practices of International Law and their Politics' (CUP, 2016). Her work on the interplay between politics and law within global governance, misrecognition, colonial treaties and interdisciplinarity has been published in various journals and handbooks in International Law and International Relations. She was a founding board member of the European International Studies Association, and editor of the Leiden Journal of International Law. She currently is series editor for Voices in IR with Oxford University Press and member of the Advisory Council International Affairs for the Dutch government.
