The Human Dimension Of Peace And Aggression, Chiara Redaelli

International Law Studies

Since the adoption of the Charter of the United Nations, the current international legal framework has drastically changed. In its traditional understanding, aggression is “the supreme international crime” aimed at protecting sovereignty and the territorial integrity of states. On the other hand, the U.N. Charter endorses an understanding of peace in the negative sense, that is, as mere absence of war. As human rights have gained momentum, they have helped reshape the legal landscape, a phenomenon referred to as the humanization of international law. How do peace and aggression fit within the humanized legal framework? This article will investigate the …

Will Cyber Autonomy Undercut Democratic Accountability?, Ashley Deeks

International Law Studies

In recent years, legislative bodies such as the U.S. Congress and the U.K. Parliament have struggled to maintain a role for themselves in government decisions to conduct military operations against foreign adversaries. Some of these challenges arise from constitutional structures, but they are also due to the changing nature of conflict: a shift away from large-scale kinetic operations and toward smaller-scale operations—including cyber operations—that are less visible and that do not require robust legislative support. These modern operations leave legislatures to engage in ex post and sometimes ineffective efforts to hold their executive branches accountable for international uses of force …

Autonomous Cyber Capabilities Below And Above The Use Of Force Threshold: Balancing Proportionality And The Need For Speed, Peter Margulies

International Law Studies

Protecting the cyber domain requires speedy responses. Mustering that speed will be a task reserved for autonomous cyber agents—software that chooses particular actions without prior human approval. Unfortunately, autonomous agents also suffer from marked deficits, including bias, unintelligibility, and a lack of contextual judgment. Those deficits pose serious challenges for compliance with international law principles such as proportionality.

In the jus ad bellum, jus in bello, and the law of countermeasures, compliance with proportionality reduces harm and the risk of escalation. Autonomous agent flaws will impair their ability to make the fine-grained decisions that proportionality entails. However, a …

Special Rules Of Attribution Of Conduct In International Law, Marko Milanovic

International Law Studies

Are there are any special rules of attribution in international law? Are there, in other words, imputational rules that are not recognized as such in general international law, but are specific to particular branches of international law? This is the first article to systematically analyze the notion of special rules of attribution in international law. In particular, it searches for such rules in international humanitarian law, the law on the use of force, and European human rights law.

The article argues that, to the extent special rules of attribution exist, they are rare and never uncontroversial. In most situations, putative …

Beyond Human Shielding: Civilian Risk Exploitation And Indirect Civilian Targeting, Geoffrey S. Corn

International Law Studies

Few violations of the law of armed conflict (LOAC) are as pernicious as using civilians to shield military objectives from attack. This unlawful tactic unfortunately seems to be an all too common practice of organized armed groups, especially in conflicts against tactically superior conventional state armed forces. The very term "human shielding" presupposes, however, the ultimate objective is to prevent an opponent from attacking the shielded military objective or, in the alternative, substantially complicate that attack decision. But is a shielding effect always the ultimate objective of such civilian exploitation? This article argues that the answer is no; that there …

Strategic Proportionality: Limitations On The Use Of Force In Modern Armed Conflicts, Noam Lubell, Amichai Cohen

International Law Studies

The nature of modern armed conflicts, combined with traditional interpretations of proportionality, poses serious challenges to the jus ad bellum goal of limiting and controlling wars. In between the jus ad bellum focus on decisions to use force, and the international humanitarian law (IHL) regulation of specific attacks, there is a far-reaching space in which the regulatory role of international law is bereft of much needed clarity. Perhaps the most striking example is in relation to overall casualties of war. If the jus ad bellum is understood as applying to the opening moments of the conflict, then it cannot provide …

The (Erroneous) Requirement For Human Judgment (And Error) In The Law Of Armed Conflict, Eric Talbot Jensen

International Law Studies

One of the most intriguing and important discussions in international law is the potential impact of emerging technologies on the law of armed conflict (LOAC), including weapons that incorporate machine learning and/or artificial intelligence. Because one of the likely characteristics of these advanced weapons would be the ability to make decisions implicating life and death on the battlefield, these discussions have highlighted a fundamental question concerning the LOAC: Does the law regulating armed conflict require human input in selecting and engaging targets or can that decision be made without human input? This article analyzes views expressed by scholars and NGOs, …

The Unlawfulness Of A “Bloody Nose Strike” On North Korea, Kevin Jon Heller

International Law Studies

The United States has reportedly been debating whether to "react to some nuclear or missile test with a targeted strike against a North Korean facility to bloody Pyongyang’s nose and illustrate the high price the regime could pay for its behavior." This article asks a simple question: would such a “bloody nose strike” (BNS) violate the jus ad bellum?

Providing a coherent answer is complicated by the lack of clarity surrounding the United States’ planning. In particular, the U.S. government has not specified what kind of provocation it believes would justify launching a BNS, has not identified precisely what …

Twelve Key Questions On Self-Defense Against Non-State Actors, Terry D. Gill, Kinga Tibori-Szabó

International Law Studies

This article examines the most pertinent questions relating to the applicability of the right of self-defense to attacks conducted by non-State armed groups (NSAGs) acting independently of State control from the territory of one or more States against the territory of another State. These questions are approached from the perspective of legality (does the right of self-defense apply to attacks not mounted by or under the control of a State) and modality (assuming the applicability of self-defense to such attacks; how do the principles of necessity, proportionality and immediacy affect its application)? Starting with an assessment of the place of …

The Occupation Of Maritime Territory Under International Humanitarian Law, Marco Longobardo

International Law Studies

This article explores whether it is possible to apply the law of occupation beyond land territory, to maritime areas characterized here as “maritime territory.” The article argues that the definition of territory under Article 42 of the 1907 Hague Regulations comprises internal waters, territorial sea, and archipelagic waters, whereas other areas such as the continental shelf, the exclusive economic zone, and high seas fall outside the scope of Article 42. Accordingly, internal waters, the territorial sea, and archipelagic waters may be placed under occupation if a hostile force exercises actual authority over them without valid legal title. The article describes …

Classification Of Cyber Capabilities And Operations As Weapons, Means, Or Methods Of Warfare, Jeffrey T. Biller, Michael N. Schmitt

International Law Studies

Despite several persistent controversies regarding how international law applies to cyber operations during an armed conflict, general understanding of the law in this domain is maturing. Reasoning by analogy to non-cyber application and interpretation of international law underlies much of the progress. Yet, although preexisting normative structures and legal terminology enable legal advisors and scholars to usefully draw upon previously acquired experience and understanding, there are obstacles to definitive analogizing that result from fundamental differences between cyber and kinetic operations. The number of imperfect analogies that underlie some of the normative uncertainty in the field underscores this point.

One key …

Beyond Geneva: Detainee Review Processes In Non-International Armed Conflict—A U.S. Perspective, Ryan J. Vogel

International Law Studies

The need for detainee review in non-international armed conflict has never been more imperative. Yet, the law of armed conflict is almost completely silent on the subject. Although the law may not require States to conduct detainee review processes in non-international armed conflict, the spirit of the law encourages it, and States—particularly the United States—have begun to see utility in the development and implementation of such review processes. The object of this article is to identify an appropriate framework for detainee review, examine relevant U.S. state practice, and provide practical guidelines for implementing processes to review the status and threat …

Weapons Review Obligation Under Customary International Law, Natalia Jevglevskaja

International Law Studies

Under Article 36 of the 1977 Additional Protocol I to the Geneva Conventions, States are required to review new weapons for their compliance with international law. While recent discussions on the regulation of lethal autonomous weapons systems under the auspices of the UN Certain Conventional Weapons Convention increasingly emphasize the importance of national weapons review mechanisms, Article 36 is known to be implemented only by a handful of States. Some legal scholars have nonetheless argued that the Article 36 obligation has attained customary international law status. Remarkably, substantive analysis of State practice and opinio juris required to evidence that certain …

The Updated Icrc Commentary On The Second Geneva Convention: Demystifying The Law Of Armed Conflict At Sea, Bruno Demeyere, Jean-Marie Henckaerts, Heleen Hiemstra, Ellen Nohle

International Law Studies

Since their publication in the 1950s and 1980s respectively, the Commentaries on the Geneva Conventions of 1949 and their Additional Protocols of 1977 have become a major reference for the application and interpretation of those treaties. The International Committee of the Red Cross, together with a team of renowned experts, is currently updating these Commentaries in order to document developments and provide up-to-date interpretations of the treaty texts. Following a brief overview of the methodology and process of the update as well as a historical background to the Second Geneva Convention, this article addresses the scope of applicability of the …

Duty To Render Assistance To Mariners In Distress During Armed Conflict At Sea: A U.S. Perspective, Raul (Pete) Pedrozo

International Law Studies

In 2017, the International Committee of the Red Cross published an updated Commentary on the Second Geneva Convention. One question left unanswered by the new Commentary is the relationship between international humanitarian law and other international treaties applicable to the maritime domain, such as the U.N. Convention on the Law of the Sea (UNCLOS) and treaties adopted by the International Maritime Organization (IMO). The Second Geneva Convention establishes a legal framework for the humane treatment and protection of victims of armed conflict at sea—the wounded, sick and shipwrecked. There are circumstances, however, in which the belligerents do not have the …

The International Legal Implications Of Military Space Operations: Examining The Interplay Between International Humanitarian Law And The Outer Space Legal Regime, Dale Stephens

International Law Studies

In the contemporary period, many military forces rely heavily on space-based assets to conduct operations across a wide spectrum of contexts. Such reliance necessarily exposes a correlative vulnerability that such assets may be degraded or destroyed, especially in a time of armed conflict. However, the legal framework that governs military action in space during a time of armed conflict is not well explored. This article examines the interaction between International Humanitarian Law (IHL) and the Outer Space legal regime. Harmonization of legal regimes is a goal of any reconciliation project, although such harmonization may not always be readily possible. In …

Armed Conflict-Related Detention Of Particularly Vulnerable Persons: Challenges And Possibilities, Sandesh Sivakumaran

International Law Studies

Persons detained for reasons related to an armed conflict are in a vulnerable position. Deprived of their liberty, they are at the mercy of their captors. Certain groups of detainees are particularly vulnerable. Additionally, the way in which non-international armed conflicts are fought can make it difficult for some parties to the conflict to comply with the rules benefiting particularly vulnerable detainees. This Article identifies groups of particularly vulnerable detainees and analyzes the general and special protections that are afforded to them under the conventional and customary international law of armed conflict. It then considers the realities of detention in …

Silent War: Applicability Of The Jus In Bello To Military Space Operations, Kubo Mačák

International Law Studies

There are no molecules of air that could carry sound waves in the vacuum of outer space. Accordingly, space warfare may well become the first type of war whose signature sound would be—silence. But does the law of armed conflict (jus in bello) fall silent in times of Silent War? This article addresses the uncertainty at the heart of this issue. First, it delineates the relevant conceptual framework by examining the factual notion of “military space operations,” and its relationship with the legal concept of “armed conflict,” as well as the overlap between the potentially applicable bodies of …

The Future Of U.S. Detention Under International Law: Workshop Report, International Committee Of The Red Cross (Icrc), Harvard Law School Program On International Law And Armed Conflict (Hls Pilac), Stockton Center For The Study Of International Law (U.S. Naval War College)

International Law Studies

The International Committee of the Red Cross Regional Delegation for the United States and Canada, the Harvard Law School Program on International Law and Armed Conflict, and the Stockton Center for the Study of International Law at the U.S. Naval War College recently hosted a workshop titled Global Battlefields: The Future of U.S. Detention under International Law. The workshop was designed to facilitate discussion on international law issues pertaining to U.S. detention practices and policies in armed conflict. Workshop participants included members of government, legal experts, practitioners and scholars from a variety of countries. This report attempts to capture the …

Fragmented Wars: Multi-Territorial Military Operations Against Armed Groups, Noam Lubell

International Law Studies

Recent years have seen the emergence of significant legal debate surrounding the use of force against armed groups located in other States. With time, it has become clear that in many cases such operations are not confined to the territory of one other State, but expand to encompass multiple territories and often more than one armed group. This article examines multi-territorial conflicts with armed groups through the lens of several legal frameworks. Among other topics, it analyses the questions surrounding the extension of self-defense into multiple territories, the classification of the hostilities with the group and between involved States, the …

Space Weapons And The Law, Bill Boothby

International Law Studies

Outer space is of vital importance for numerous civilian and military functions in the modern world. The idea of a space weapon involves something used, intended or designed for employment in, to or from outer space to cause injury or damage to the enemy during an armed conflict. Non-injurious, non-damaging space activities that adversely affect enemy military operations or capacity, though not involving the use of weapons, will nevertheless be methods of warfare. Article III of the Outer Space Treaty makes it clear that international law, including weapons law, applies in outer space. Accordingly, the superfluous injury/unnecessary suffering and indiscriminate …

The Updated Commentary On The First Geneva Convention – A New Tool For Generating Respect For International Humanitarian Law, Lindsey Cameron, Bruno Demeyere, Jean-Marie Henckaerts, Eve La Haye, Heike Niebergall-Lackner

International Law Studies

Since their publication in the 1950s and the 1980s respectively, the Commentaries on the Geneva Conventions of 1949 and their Additional Protocols of 1977 have become a major reference for the application and interpretation of these treaties. The International Committee of the Red Cross (ICRC), together with a team of renowned experts, is currently updating these Commentaries in order to document developments and provide up-to-date interpretations. The work on the first updated Commentary, the Commentary on the First Geneva Convention relating to the protection of the wounded and sick in the armed forces, has already been finalized. This article provides …

A Human Rights Perspective To Global Battlefield Detention: Time To Reconsider Indefinite Detention, Yuval Shany

International Law Studies

This article discusses one principal challenge to detention without trial of suspected international terrorists—the international human rights law (IHRL) norm requiring the introduction of an upper limit on the duration of security detention in order to render it not indefinite in length. Part One of this article describes the “hardline” position on security detention, adopted by the United States in the immediate aftermath of the 9/11 terror attacks (followed, with certain variations, by other countries, including the United Kingdom and the State of Israel), according to which international terrorism suspects can be deprived of their liberty without trial for the …

The Limits Of Inviolability: The Parameters For Protection Of United Nations Facilities During Armed Conflict, Laurie R. Blank

International Law Studies

This article examines the international legal protections for United Nations humanitarian assistance and other civilian facilities during armed conflict, including under general international law, setting forth the immunities of the United Nations, and the law of armed conflict (LOAC), the relevant legal framework during wartime. Recent conflicts highlight three primary issues: (1) collateral damage to UN facilities as a consequence of strikes on military objectives nearby and military operations in the immediate vicinity; (2) the misuse of UN facilities for military purposes; and (3) direct attacks on fighters, weapons or other equipment that cause damage to such facilities. To identify …

Detention By Armed Groups Under International Law, Andrew Clapham

International Law Studies

Does international law entitle armed groups to detain people? And what obligations are imposed on such non-state actors when they do detain? This article sets out suggested obligations for armed groups related to the right to challenge the basis for any detention and considers some related issues of fair trial and punishment. The last part of this article briefly considers the legal framework governing state responsibility and individual criminal responsibility for those that assist armed groups that detain people in ways that violate international law.

Chemical Weapons And Other Atrocities: Contrasting Responses To The Syrian Crisis, Tim Mccormack

International Law Studies

Why has the use of chemical weapons in Syria engendered such a substantive multilateral response in stark contrast to almost every other egregious international law violation perpetrated against the civilian population? Various theories have been offered but the explanation has little to do with humanitarian concerns for Syrian victims and is more readily explicable by unusual (in the Syrian context) alignment of U.S. and Russian national interests. Bashar al-Assad was convinced to accede to the Chemical Weapons Convention, to surrender his stockpiles of chemical weapons and to co-operate with international investigators deployed under UN Security Council auspices amid a cacophony …

Arbitrary Withholding Of Consent To Humanitarian Relief Operations In Armed Conflict, Dapo Akande, Emanuela-Chiara Gillard

International Law Studies

This article examines the requirement under international humanitarian law (IHL) that consent to humanitarian relief operations must not be arbitrarily withheld. It begins with a brief outline of the rules of IHL regulating humanitarian assistance in armed conflict. The article then considers the origin of the rule prohibiting arbitrary withholding of consent to humanitarian relief operations before proceeding to set out the circumstances when consent will be considered to have been withheld arbitrarily under international law. It proposes three tests for arbitrariness in this context, and also examines how international human rights regulates humanitarian assistance in armed conflict.

Soldier 2.0: Military Human Enhancement And International Law, Heather A. Harrison Dinniss, Jann K. Kleffner

International Law Studies

Advances in technologies that could endow humans with physical or mental abilities that go beyond the statistically normal level of functioning are occurring at an incredible pace. The use of these human enhancement technologies by the military, for instance in the spheres of biotechnology, cybernetics and prosthetics, raise a number of questions under the international legal frameworks governing military technology, namely the law of armed conflict and human rights law. The article examines these frameworks with a focus on weapons law, the law pertaining to the detention of and by “enhanced individuals,” the human rights of those individuals and their …

Partners And Legal Pitfalls, Brian Finucane

International Law Studies

Partnered military operations are an increasingly prominent feature of armed conflict and one which presents a distinct set of legal challenges to States assisting partners. This is particularly true of the war in Syria which is characterized both by States working with and through other States and non-State actors and by the widespread violation of the law of armed conflict (LOAC) by many of the parties. This article considers the legal implications of LOAC violations by a party to the conflict for the State or States providing it assistance and identifies risk mitigation measures that assisting States can adopt.

Classifying The Conflict In Syria, Terry D. Gill

International Law Studies

This article examines the classification of the current armed conflict in Syria under international humanitarian law. The article first sets out the factual background identifying the principal parties and their alignments and motivations. It then proceeds to examine the question of classification of conflict under international humanitarian law and discusses the contentious issue of the effect of lack of consent by the government of a State in relation to foreign intervention in an ongoing non-international armed conflict when such intervention is directed against one or more armed groups operating from within that State’s territory. It then proceeds to apply these …
