Episode 28 – The War in Ukraine: Jus ad Bellum Implications

by

 

 

 

 

 

In this special episode, I discuss aspects of the Russian invasion of Ukraine with Professors Eliav Lieblich of Tel Aviv University Faculty of Law, Marko Milanovic of the University of Nottingham School of Law, and Ingrid Wuerth of Vanderbilt University School of Law. The focus of our discussion is how we should be thinking about what this war means for the jus ad bellum regime and the collective security system. While the invasion is clearly an unlawful and egregious act of aggression, have unlawful uses of force by Western states served to weaken the system in a way that is in any way relevant to the current conflict? Has the focus on humanitarian issues, and human rights law more generally, somehow similarly weakened the system? Should this war be understood as a failure of the collective security system? Is there a risk that the wrong lessons may be drawn from the conflict, particularly in the area of nuclear non-proliferation? And, perhaps most importantly, how should we begin to think about restoring or even reforming both the jus ad bellum regime and the collective security system more broadly? A fascinating discussion about hugely important issues.

Season 3: Episode 26 – Olivier Corten on The Law Against War

by

In this first episode of Season 3 of the podcast, I speak with Olivier Corten, Professor of International Law at the Center for International Law, Free University of Brussels, in Belgium. Olivier specializes in both the international law on the use of force, and international law theory, and was the Director of the Center for International Law at Free University of Brussels until 2019. In our conversation we discuss the 2nd edition of his book The Law Against War, which was published in late 2021 (the first edition was published in 2010). We begin with his analysis of the differing methodological approaches – what he calls the restrictive and the expansive approach – to international law on the use of force. From there, our conversation moves on to explore the substantive content of the book, beginning with the threshold for what constitutes a use of force, and moving through the scope and operation of the doctrine of self-defense, including the proper understanding of the role played by the principle of necessity, the validity of any and all conceptions of anticipatory self-defense, the use of force by invitation, and whether and how the law on the use of force applies to actions against non-state actors, and to cyber operations. We end where we started, discussing the problem posed by the very different theoretical and methodological approaches to an understanding of the jus contra bellum, and how one might think about bridging the divide.

Episode 14 – Federica Paddeu on Consent as a Justification for the Use of Force

by

In this episode I speak with with Federica Paddeu, Professor and Derek Bowett Fellow in Law at Queen’s College, Faculty of Law, Cambridge University in England. We discuss her recent work on how best to understand the operation of consent as a justification for the use of force in international law—is it part of, or intrinsic to, the definition of the prohibition on the use of force in Article 2(4) of the Charter? Or is it extrinsic, a separate and independent exception or justification for the use of force? Consider how consent operates quite differently in the crimes of rape (intrinsic to the definition) and battery (extrinsic defense). Our discussion makes clear that the answer to the question of how consent operates has important implications for how we think about and understand the nature of the use of force itself, on whether the prohibition in its entirety can be a jus cogens norm, as well as for how the justification ought to operate in practice. We end by also discussing her earlier work on self-defence as a circumstance precluding wrongfulness (work that will change how you understand that too), and how her thinking about exceptions and justifications in the jus ad bellum has evolved over the course of her intellectual journey. A fantastic conversation!

Episode 10 – Eliav Lieblich on the Humanization of Jus ad Bellum

by

In this episode, I speak with Eliav Lieblich, Professor of Law at The Buchmann Faculty of Law, Tel Aviv University, Israel, about the relatively under-studied relationship between international human rights law and the use of force by states. Eliav, in a forthcoming article, uses a recent General Comment of the U.N. Human Rights Committee as a point of departure for analyzing whether, and to what extent, violations of the jus ad bellum regime might also violate the right to life enshrined in the International Covenant on Civil and Political Rights. Thus, does an act of aggression by a state infringe human rights law as well as violate the jus ad bellum regime? And do governments contemplating the use of force in self-defense have to consider the human rights obligations owed to its own citizens, and the rights of the people in the state against which it is intending to use force? Eliav explores these fascinating questions, and their important implications, from not only a doctrinal and theoretical perspective, but also through the lens of just war theory and ethics as well.

Episode 3 – Adil Haque on the Use of Force, Aggression, and Self-Defense

by

In this episode, I speak with Adil Haque, Professor of Law and Judge Jon O. Newman Scholar at Rutgers Law School. Our discussion focuses primarily on two recent blog posts on Just Security, in which Adil explores the relationship between the use of force, aggression and self-defense. Based on extensive research into the travaux preparatoire for the U.N. Charter, Adil suggests that self-defense is not exactly an exception to the prohibition on the use of force in Art. 2(4) of the Charter, but rather is an exception that only the U.N. Security Council may authorize the use of force to deal with aggression. What is more, self-defense is then understood as being in response to aggression, and that an “armed attack” as used in Art. 51 of the Charter must be understood in these terms. As Adil explains, this both reinforces some of the standard views on self-defense, but also alters and challenges some of those views. It is a conversation that will likely have you questioning your understanding of the relationship! We also briefly discuss his book, Law and Morality at War, at least enough to make you want to read it.
