Manifestly Unlawful: Why Russian Military Commanders Must Disobey A Nuclear Launch Order Against Ukraine, Christopher J. Hart

International Law Studies

Applying the international legal framework governing the use of nuclear weapons to the facts of the war in Ukraine leads to a clear answer to the question of whether the use of nuclear weapons in Ukraine by Russia would be legal. While the 1996 International Court of Justice Advisory Opinion on the Threat or Use of Nuclear Weapons did not conclusively decide whether the use of nuclear weapons was per se illegal, by applying the legal framework articulated by the International Court of Justice to the facts of Russia’s war against Ukraine it is clear that any conceivable use of …

Legal Reviews Of War Algorithms, Tobias Vestner, Altea Rossi

International Law Studies

States and scholars recognize legal reviews of weapons, means or methods of warfare as an essential tool to ensure the legality of military applications of artificial intelligence (AI). Yet, are existing practices fit for this task? This article identifies necessary adaptations to current practices. For AI-enabled systems that are used in relation to targeting, legal reviews need to assess the systems’ compliance with additional rules of international law, in particular targeting law under international humanitarian law (IHL). This article discusses the procedural ramifications thereof. The article further finds that AI systems’ predictability problem needs to be addressed by the technical …

Command Accountability For Ai Weapon Systems In The Law Of Armed Conflict, James Kraska

International Law Studies

The use of artificial intelligence (AI) in weapon systems enhances the ability of operational forces to fuse multispectral sensors to understand the warfighting environment, positively identify, track, and select targets, and engage them with the most appropriate effects. The potential for AI to help close the “kill chain” has raised concern that this creates a gap in accountability between the decisions of humans and the acts of machines, with humans no longer accountable for decisions made during armed conflict. This study suggests that there is no gap because the military commander is always directly and individually accountable for the employment …

Autonomy And Precautions In The Law Of Armed Conflict, Eric Talbot Jensen

International Law Studies

Already a controversial topic, legal debate and broader discussions concerning the amount of human control required in the employment of autonomous weapons—including autonomous cyber capabilities—continues. These discussions, particularly those taking place among States that are Parties to the 1980 Certain Conventional Weapons Convention, reveal a complete lack of consensus on the requirement of human control and serve to distract from the more important question with respect to autonomy in armed conflict: under what conditions could autonomous weapons “select” and “attack” targets in a manner that complies with the law of armed conflict (LOAC).

This article analyzes the specific LOAC rules …

Lethal Autonomous Weapon Systems: Translating Geek Speak For Lawyers, Linell A. Letendre

International Law Studies

This article provides an overview of robotics and autonomous systems so that attorneys can better understand the systems and design principles of lethal autonomous weapon systems (LAWS) that may be used in an armed conflict. Using the lens of establishing a common language between engineers and attorneys, the article introduces the basics of robotics terminology, explores how autonomous systems work by explaining control systems and control architecture, and examines how autonomous systems learn and reason. It also suggests a number of questions attorneys should ask engineers during the design process in order to ensure autonomous systems are designed in a …

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, …

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 …

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 …

Are Enhanced Warfighters Weapons, Means, Or Methods Of Warfare?, Rain Liivoja, Luke Chircop

International Law Studies

Advances in science and technology have made it possible to improve the physical and cognitive capabilities of warfighters by biomedical interventions, such as the administration of drugs, the implantation of devices, and the magnetic stimulation of the brain. These advances raise the question as to whether enhanced warfighters ought to be considered weapons, means of warfare, or methods of warfare, for the purposes of the law of armed conflict. An affirmative answer to this question would make human enhancement subject to various restrictions arising from the law of armed conflict as well as arms control law. This article disagrees with …

Autonomous Weapons And Weapon Reviews: The Uk Second International Weapon Review Forum, James Farrant, Christopher M. Ford

International Law Studies

This article considers how military lawyers completing weapon reviews might approach their legal duties if confronted with a weapon system that incorporates autonomous technology or artificial intelligence. The article begins by reviewing current and likely near future technological capabilities before considering whether existing international humanitarian law can adequately regulate these technologies. While noting the widespread lack of compliance with Article 36 of Additional Protocol I, the article argues that, properly applied, Article 36 is an effective gatekeeper for keeping unlawful weapon systems from the battlefield. After assessing the feasibility of a preemptive ban on autonomous weapons based on “meaningful human …

The Conduct Of Hostilities And International Humanitarian Law: Challenges Of 21st Century Warfare, International Law Association Study Group On The Conduct Of Hostilities In The 21st Century

International Law Studies

The International Law Association Study Group on the Conduct of Hostilities in the 21st Century was established in 2011 and held its first meeting in 2012. The Study Group has explored numerous issues arising from the relationship between international humanitarian law (IHL) and international human rights law in the conduct of military operations, technological challenges posed by new weapons systems, and the basic principles of IHL in the conduct of hostilities. In 2015, the Study Group established three working groups focusing on core issues within IHL in relation to the conduct of hostilities in modern warfare. These working group topics …

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 …

Combat Losses Of Nuclear-Powered Warships: Contamination, Collateral Damage And The Law, Akira Mayama

International Law Studies

There have been non-combat losses of nuclear-powered warships during sea trials and peacetime patrol missions. Nuclear contamination is spreading from some of these sinking sites. It is also conceivable that combat losses of nuclear-powered warships could cause contamination of civilians, civilian objects and the natural environment. If such combat losses occur at sea, both belligerent and neutral States will have to deal with a difficult question: to what extent and by who can harm resulting from such contamination be compensated for payment of damages. This article examines legal issues stemming from prospective combat losses of nuclear-powered warships from the perspectives …

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 …

Syria: Can International Law Cope? Workshop Report, Christopher M. Ford

International Law Studies

The Stockton Center for the Study of International Law at the U.S. Naval War College and the Center for the Rule of Law at the U.S. Military Academy convened a three-day workshop in November 2015. The workshop sought to examine the question posed by its title: Can International Law Cope with the Situation in Syria? It is a question that has ramifications for the viability of international law well beyond the confines of events in Syria. This report surveys the key issues that were raised during the workshop and serves as an introduction to the articles that follow in this …

Mapping War Crimes In Syria, Beth Van Schaak

International Law Studies

This article maps the range of war crimes being committed in Syria with reference to the applicable treaty and customary international law and prospects for prosecution. It begins by presenting the international legal framework employed to determine when an armed conflict began in Syria, how this conflict is classified under international law and which multilateral treaties and customary rules are operative. This framework underlies the determination of which war crimes can be prosecuted, which tribunals might have jurisdiction and which perpetrators may be made subject to indictment. The article next focuses on some open legal and factual issues around certain …

Twenty Seconds To Comply: Autonomous Weapon Systems And The Recognition Of Surrender, Robert Sparrow

International Law Studies

Would it be ethical to deploy autonomous weapon systems (AWS) if they were unable to reliably recognize when enemy forces had surrendered? I suggest that an inability to reliably recognize surrender would not prohibit the ethical deployment of AWS where there was a limited window of opportunity for targets to surrender between the launch of the AWS and its impact. However, the operations of AWS with a high degree of autonomy and/or long periods of time between release and impact are likely to remain controversial until they have the capacity to reliably recognize surrender.

Regulation-Tolerant Weapons, Regulation-Resistant Weapons And The Law Of War, Sean Watts

International Law Studies

The historical record of international weapons law reveals both regulation-tolerant weapons and regulation-resistant weapons, identifiable by a number of criteria, including effectiveness, novelty, deployment, medical compatibility, disruptiveness and notoriety. This article identifies these criteria both to explain and inform existing weapons law, and also to facilitate efforts to identify weapons and emerging technology that may prove susceptible to future law of war regulation. By charting both the history and methodology of weapons law with a view toward identifying forces and influences that have made some weapons susceptible to international regulation and made others resistant, this article offers a starting point …

Emerging Technologies And Loac Signaling, Eric Talbot Jensen

International Law Studies

As States seek to weaponize new technologies such as robotics, cyber tools and nanotechnology, the current law of armed conflict (LOAC) that guides the employment of existing weapons will signal rules and principles that should guide national decisions on what new technologies to weaponize and how to do so in a way that ensures compliance with battlefield regulation. LOAC has served this "signaling" function historically with respect to innovative weapon systems such as balloons, submarines, airplanes, and nuclear weapons, and will continue to do so as nations look forward to potentially weaponizing emerging technologies.

Nanotechnology And The Future Of The Law Of Weaponry, Hitoshi Nasu

International Law Studies

Novel applications of nanotechnology for military purposes are expected to have a transformative impact on the way in which wars can be fought in the future battlespace, with the potential to drive changes to the law of weaponry. This article considers the potential of military applications of nanotechnology to bring changes to the existing principles and rules of weapons law. It specifically focuses on the likelihood that more sophisticated, miniaturized and tailored weapons and weapon systems will be produced that enable mechanical precision of targeting with no or few civilian casualties.

Emerging Technology And Perfidy In Armed Conflict, Ian Henderson, Jordan Den Dulk, Angeline Lewis

International Law Studies

The rule against perfidy in armed conflict—one of the last echoes of honor and social order of war—is threatened by emerging technologies. Specifically, the employment of emerging technologies has muddied the already thin and grey line between acts which contravene the honor of warfare and legitimate ruses of war. In this article, the authors analyze perfidy, treachery and ruses of war as key concepts of international humanitarian law and consider their application to emerging technologies.

Mind The Gap: Can Developers Of Autonomous Weapons Systems Be Liable For War Crimes?, Tim Mcfarland, Tim Mccormack

International Law Studies

A recurrent response to the development of increasingly autonomous weapons systems involves questions of accountability for serious violations of the law of armed conflict. Opinion is divided across a spectrum ranging from claims of an accountability vacuum and consequent calls for a complete ban to assertions that the weapons will present no new challenges and that the existing legal framework is capable of adaptation to emerging technologies. This article focuses on the expanded role played by developers of autonomous weapons systems. It describes the novel contributions made by developers of these advanced systems that raise the potential for them to …

Autonomous Weapons And International Humanitarian Law: Advantages, Open Technical Questions And Legal Issues To Be Clarified, Marco Sassoli

International Law Studies

This contribution argues that autonomous weapons systems may have advantages from the perspective of ensuring better respect for international humanitarian law (IHL). This may be the case if they are one day capable of perceiving the information necessary to comply with IHL, can apply IHL to that information, and if it can be ensured that they will not deviate from the ways in which humans have programmed them. In the view of the author, targeting decisions do not require subjective value judgments a machine would be unable to make. In order to ensure IHL is respected with regard to use …

Adapting The Law Of Armed Conflict To Autonomous Weapon Systems, Kenneth Anderson, Daniel Reisner, Matthew Waxman

International Law Studies

As increasingly automated—and in some cases fully autonomous—weapon systems enter the battlefield or become possible, it is important that international norms to regulate them head down a path that is coherent and practical. Contrary to the claims of some advocates, autonomous weapon systems are not inherently illegal or unethical. The technologies involved potentially hold promise for making armed conflict more discriminating and causing less harm on the battlefield. They do pose great challenges, however, with regard to law of armed conflict rules regulating the use of weapons. To adapt existing law to meet those challenges, we propose a three-tiered approach …
