insist – in the perception – of how Brazil sees and values international law. As a scholar, he put the protection and defense of human rights at the center of international law. That it is a recurring theme in Brazilian academia and not unfortunately in other countries. This brings me back to his progressive understanding of international law. I remember, once he told me: “I am an international law activist, not just an operator”. From his perspective, it is not just about -operating- international law and international relations, but he...

[ Jens David Ohlin is an Associate Professor of Law at Cornell Law School; he blogs at LieberCode .] In April 2011, a group of legal scholars gathered at the University of Pennsylvania Law School for a conference on targeted killings. The idea was to bring together experts in diverse fields – international law, legal and moral philosophy, military law, and criminal law – into a single (or perhaps overlapping) conversation about the legality and morality of targeted killings. The outgrowth of that conference, Targeted Killings: Law and Morality in...

(Article 2.1). This restrictive approach was the result of extensive debate surrounding whether to adopt a wide horizontal approach or extend the existing sectoral approach to whistleblowing within the EU. The horizontal approach – such as that envisioned by the European Parliament – involved covering all workers in the public and private sectors without limitation. By contrast, the European Commission, finding that there was no legal basis in the Treaties allowing the EU to regulate whistleblowing in general, opted rather to widen the existing EU sectoral approach (see White 2018...

the approach taken in determining the existence of an armed attack naturally has similarity with the approach taken in determining what constitutes use of force prohibited under article 2(4) of the UN Charter.  These similarities between Erin Pobjie’s proposed approach towards use of force and the traditional approach taken in our Diet answers on an armed attack make her basic approach understandable and agreeable for me.  Possible Application to Acquisition of Territory by Force Having said that, I have several observations on the contents of her book, which I hope...

[Juan Auz is an Ecuadorian lawyer and a postdoctoral researcher at Tilburg University’s Law School] On March 14, 2025, the Inter-American Court of Human Rights (IACtHR) made public a landmark ruling holding Ecuador internationally responsible for the violation of various rights of the Tagaeri and Taromenane, the last remaining indigenous peoples living in voluntary isolation (PIAV) in the western Ecuadorian Amazon (for an early commentary see here). This entry explores how the judgment reaffirmed the IACtHR’s expansive approach to Indigenous rights and ventured into uncharted legal territory by treating the...

law itself is primarily anthropocentric. So far, it has been the anthropocentric approach that has convinced humans to adopt environmental protections, enabling progress in environmental law. Rightly or wrongly, contemporary IEL largely focuses on management of shared resources, global commons problems, negative transboundary externalities, and intergenerational equity (ie sustainable development not zero-impact). The approach has produced major efforts to curb air and water pollution and control toxic products. Some people are rightly pushing to make environmental law more ecocentric, which is valuable in many areas. But in 2021, some anthropocentric...

...the final stage of the phenomenon, there are several stages that link complete failure to a fully functioning State, depending on the residual capacity of a State to fulfill its obligations. I believe that any approach to address crisis situations of State failure and fragility must take into consideration these differences. I suggest that the adoption of a set of recognized, common and agreed principles could be useful in guiding actions by the international community in situations of State failure and fragility. These principles would ensure the lawfulness and consistency...

in centring survivors in this process.  This blog focuses on the importance of a survivor-centred approach when implementing reparation, explores the main findings of the ICC Chamber in the Ongwen case in this regard, and discusses next steps and challenges that the ICC will face to make the implementation process truly victim centred. The Importance of Survivor-Centred Reparation The significance of reparation being survivor-centred cannot be overstated, aligning directly with a victim’s      right to prompt, adequate, and effective reparation under international law. This approach places the rights, needs,...

[Hari M. Osofsky is Associate Professor and 2011 Lampert Fesler Research Fellow, University of Minnesota Law School and Associate Director of Law, Geography & Environment, Consortium on Law and Values in Health, Environment & the Life Sciences] I am grateful for the opportunity to participate in this exchange over Tai-Heng Cheng’s ambitious and thoughtful new book, When International Law Works. Opinio Juris enhances the international law dialogue by providing these opportunities for more informal, timely discourse on important topics. As the final commentator in this interchange, I have had the...

international law, reparations are traditionally regarded as a means of redressing harm caused by breaches of international law. However, for the victims themselves, reparations often hold much broader significance. Those who have been subjected to unlawful deprivation of liberty, torture or other forms of ill-treatment often speak of losses that cannot be fully compensated. They talk about years spent in captivity, broken families, lost businesses or careers, as well as the physical and psychological damage that can stay with a person for the rest of their life. This experience also...

to an effective remedy. At the same time, investigations should be conducted by independent and impartial bodies and prosecute crimes committed by all parties in the armed conflict. It is also relevant to adopt a gendered approach because conflict-related sexual violence crimes frequently remain invisible, perpetuating impunity. Amnesty Laws The adoption of amnesty laws is probably one of the most controversial aspects of negotiating a peace settlement. Some consider amnesty laws to be an obstacle for justice, while others consider amnesty measures essential for sustainable peace. In international law, amnesty...

[Elvina Pothelet is a Ph.D. candidate at the University of Geneva. Her research interests focus on the international law governing the use of force, the law of armed conflict and war crime law.] Kubo Mačák’s book is a rich and thought-provoking contribution to the scholarship on IHL applicability. The writing style and structure of the book make it a smooth and enjoyable read – to the extent this is possible for a book dealing with armed conflicts. The author’s expert analysis of the law is enriched with plenty of historical...
