In this talk, I’ll focus on multiple dimension of the global housing crisis - affordability, homelessness, loss of homes due to climate crisis, mass destruction of homes or domicide during conflict, migration and the idea of a home, the contestation over land, and the persistence of forced evictions, discrimination and increasing segregation - from an international legal perspective. Drawing on my…
Lecture summary: President Trump’s decisive attack on foreign aid and USAID, leading to the restructuring of the latter and the closure of ongoing and future development aid work across the world, has left many vulnerable regions of the world in potential crisis. With some of the funds hitherto allocated to development aid in vulnerable Global South countries reallocated to national economic…
Based on his experience, but speaking in his personal capacity, Ambassador Tomohiro Mikanagi will discuss the current state of the rules of international law against attempts to acquire territory by force. When powerful States are not satisfied with the territorial status quo and are unwilling to give up their interests for the sake of international peace, there is an inherent difficulty in…
Lecture summary: In 1963, Stanley Hoffmann told the American Society of International Law: “Since every Power wants to turn its interests, ideas and gains into law, a study of the ‘legal strategies’ of the various units, i.e., of what kinds of norms they try to promote, and through what techniques, may be as fruitful for the political scientist as a study of more purely diplomatic, military or…
Lecture summary: Early March 1946 marked a rough midpoint in proceedings before the International Military Tribunal at Nuremberg. The prosecution had closed its case, with France and the USSR just having presented most of the trial’s eyewitnesses – two of them women. The defense opened just as Churchill gave his Iron Curtain speech. Elsewhere in Palace of Justice, personnel were going home even as…
Lecture summary: The regulation of submarines has rarely been an issue of focus in international law. Their military utility has influenced states’ willingness to develop rules that restrict their operations, both historically and in contemporary settings. So much is evident in examining current controversies over navigational rights of warships. Yet the types and uses of submarines are…
Speaker: Prof Tamsin Paige, Deakin Law School Lecture summary: Stories serve an integral role in society as, among other things, a meaning making tool. As a method of meaning making, stories are relational and allow the storyteller to assist their audience in understanding ideas, concepts, and experiences that lie beyond their lived experiences. Using this understanding and starting point, I ask…
Speaker: Dr Penelope Ridings, International Law Commission Lecture summary: In the last several decades, scholarly views of due diligence in international law have shifted from due diligence as a primary obligation under customary international law, to due diligence as a standard of conduct attached to a primary obligation. Thus, for example, due diligence is required to meet a State’s obligation…
Speakers: Prof Mads Andenas & Prof Johann Ruben Leiss, University of Oslo Lecture summary: The lecture explores the systemic function of general principles in international law in light of the ongoing work of the ILC on general principles of law and recent practice of international courts and tribunals, such as the Climate Change Advisory Opinion of the International Court of Justice from 2025. In…
Lecture summary: Empire is a big theme in international law. At the same time, the historical discussion on imperialism and international law had focussed primarily on the West European Empires. This presentation examines Russian and Soviet historical engagements with international law through imperial ideas and practices. Of the doctrines of international law, the ideas of state identity…
Speaker: Prof Antonios Tzanakopoulos, University of Oxford No lecture summary available. Chair: Prof Jan Klabbers This lecture was given on 23 January 2026 and is part of the Friday Lunchtime Lecture series at the Lauterpacht Centre.
The speaker for the Eli Lauterpacht Lecture 2025 was Santiago Villalpando , Legal Advisor and Director of UNESCO. Lecture summary: Is international law facing a decline of treaties? In recent years, several authoritative voices have pointed out certain developments which seem to indicate that States are shifting away from treaty law-making for the governance of their international relations.…
Lecture summary: Over centuries and across continents, authoritarian governments have demonstrated a large appetite for international cooperation to target political opponents across borders. As the world’s premier body for international police cooperation, Interpol is not supposed to facilitate this kind of transnational repression -- and yet, in recent years, there is growing concern that…
Lecture summary: Most observers – at least in the West – agree that the twenty-first century has been particularly tumultuous. But while some explain the volatility of our times by reference to historical analogies, e.g. moments of power transition in the twentieth century, others claim that we are in a moment of polycrisis for which there is no precedent. In this talk I split the difference:…

International organizations law has always revolved around the relationship between the organization and its member states. This has proven to be of some use, but leaves important gaps unaddressed. What, e.g., about purely international affairs (think judicial review, think relations between organs)? And it ignores the existence of a vast external world. By concentrating solely on the relations…

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…
Lecture summary: This lecture will explore the parameters of State immunity at the international level and as reflected in different national legal systems (including England & Wales, the United States and others). It will include an overview of foundational and more recent jurisprudence in international and domestic courts, and will give particular focus to select aspects of State immunity in the…
Summary: This talk explains Sudan’s descent into a horrific war that is the world’s worst humanitarian crisis. The war has displaced over 11 million people, involved the targeting of civilians, including especially women, in mass violence, and precipitated a hunger crisis affecting over 24 million people, with over 630,000 currently facing famine. How, after a momentous civilian uprising in…
Lecture summary: Property is a fundamental legal institution governing the use of things: who may own what, how and why. Given that such questions extend to a wide range of natural resources essential to human well-being, such as food, water and shelter, then it is reasonable to assume that human rights should play an important role in shaping property rights discourse and practice. And yet this…
Panel: '(Non-)Defining 'Gender' in the Crimes Against Humanity Draft: Possibilities, Alliances, and Strategies' Feminist activists, country representatives, and other civil society actors have debated how to define “gender” in international criminal law (ICL) for at least three decades. In the Rome Conference that established the International Criminal Court (ICC) and its Statute in 1998, defining…
Sovereign debt crises have surged since the end of the Bretton Woods system and currently threaten a lost decade for many countries across the world. Indermit Gill, in the World Bank Group’s 2024 International Debt Report, describes the situation in many of the poorest countries as a ‘metastasising solvency crisis that continues to be misdiagnosed as a liquidity problem’. Despite their severe…

Speaker: Gregory Fox, Wayne State University Date: Friday Lunchtime Lecture - Friday 24 January 2025 Summary: Does international law place any constraints on a possible Ukraine-Russia peace agreement? While we can only speculate about its contents, two aspects appear certain: Ukraine will be asked to relinquish (at a minimum) territory now occupied by Russia, and it will only contemplate entering…
Lecture summary: Many political economists, economic historians, and historical sociologists understand the transition from the 1970s to the 1980s as involving a shift from debates about inflation, oil shocks, floating currencies, and the New International Economic Order to neoliberalism's political and ideological breakthrough, first in the industrialized states of the North Atlantic and shortly…
Lecture summary: In this talk Sharifah Sekalala examines this critical moment in the making of Global Health Law, with two treaty making processes: the newly finalised revisions of the International Health Regulations and ongoing negotiations by the Intergovernmental Negotiation Body for a possible pandemic Accord or Instrument, as we well as soft-law proposals for the World Health Organization…
Lecture summary: The United Nations Charter order (UNCO) and the co-evolved liberal international order (LIO) are contested with a heretofore unknown force. The steep rise in contestations in the realm of public politics rather than the courtroom demonstrates a shift from normal contestation as a source of legitimacy and ordering towards deep contestation as a political challenge of foundational…
Lecture summary: Grand corruption – the abuse of public office for private gain by a nation's leaders (kleptocrats) - has devastating consequences. As then UN High Commissioner for Human Rights Navi Pillay said, the amount lost to corruption each year is enough to feed the world's hungry 80 times over. Grand corruption contributes to climate change and is a major impediment to ameliorating it. The…
Lecture summary: Part 1 of the Lecture focuses on the development of the right to self-determination as a rule of customary international law and its application to the Chagos Archipelago, Africa and the Commonwealth Caribbean. The adoption of Resolution 1514 by the General Assembly of the United Nations on December 14, 1960 was a decisive element in the development of the customary character of…
Lecture summary: At a time where questions abound about the state and future of international cooperation and compliance across the international legal system, this lecture will consider the new partnership of countries established in 2019 to promote and protect media freedom globally – the Media Freedom Coalition of States. The Coalition offers a new paradigm that seeks to answer some of the…
Professor Daniel Bodansky’s seminal and widely acclaimed book The Art and Craft of International Environmental Law was first published in 2010. In contrast to other general works on international environmental law, the book focused on the processes of developing, implementing, and enforcing international environmental law rather than on legal doctrine. In order to comprehensively analyse these…
Lecture summary: A growing body of interdisciplinary scholarship explores overlaps and interactions among different normative and institutional branches of international law. This lecture contributes to this scholarship through a case study of relations among international organizations in the mid-1960s, when several emerging political fault lines – between East and West, between ‘developed’ and…
Lecture summary: In 2015, the United States military dropped a bomb on a hospital in Afghanistan run by Médecins Sans Frontières, killing forty-two staff and patients. Testifying afterwards before a Senate Committee, General John F. Campbell explained that “[t]he hospital was mistakenly struck.” In 2019, while providing air support to partner forces under attack by ISIS, the U.S. military killed…
Lecture summary: This lecture examines the treatment of marine genetic resources (MGR) in the negotiations and the text of the new Treaty on Biodiversity Beyond National Jurisdiction (BBNJ). The Treaty provides a coherent governance framework for MGR including an unexpected techno-fix to the most longstanding problem of biodiversity governance, some normative novelty on principles, and a…
Lecture summary: From European colonialism to the ‘post’colonial constellation, modern international law has developed in parallel with the changing legal forms of industrialised countries’ access to the natural resources of the global South. Following this development, we can see how imperial environmentalism was translated to the transnational law of natural resources. The historic perspective…

Lecture summary: This lecture considers what Josef Kunz termed “swings of the pendulum” in international monetary and financial law and the formal and informal institutions in these related fields. International monetary law exploded in importance after the Second World War with the creation of the International Monetary Fund (IMF) and a global system of managed exchange rates. With the collapse…
Lecture summary: This paper looks at the political purchase of International Conflict Feminism (ICF) in helping constitute the normative framework guiding and legitimizing laws and policies advanced under the rubric of Countering Violent Extremism (CVE). It attends to how these have intersected with the work of the international criminal court (ICC) in new modalities of lawfare that have taken…
Lecture summary: This research examines international law’s longstanding entanglement with communications infrastructure. There is increasing concern regarding the rise of private global power in the form of global digital platforms and their model of information capitalism. This paper responds by focusing on historical connections between international law and infrastructure as a means of…
Lecture summary: In this talk, Lucas Lixinski examines the erasure of Indigenous perspectives from the literature on the turn to history in international law. Considering the turn to history’s promise to offer alternative imaginations by recovering history, it is somewhat surprising and disappointing that so much of this turn is narrated from the perspective of colonisers. Lixinski unpacks the…
Lecture summary: After the conclusion of the United Nations Convention on the Law of the Sea and the entry into force of its Article 108, the subject of maritime crimes has experienced many important developments. Indeed, at present, States have to deal with criminal actions which did not exist in the classical International Law of the Sea. Relevant examples include kidnapping and hostage-taking…
