Unclos And The Law Of Occupation: On The Rights And Duties Of Occupying States In Maritime Areas, Louis M. Monroy

International Law Studies

As of today, the framework of ocean governance of coastal maritime areas created by the United Nations Convention on the Law of the Sea (UNCLOS) is well understood and accepted by the international community. However, there are large and important areas of ocean space around the world that are subject to a more nuanced framework of interrelated norms. These are maritime areas that have come under the effective control of occupying States, often through the use of force. As such, the legal framework applicable to these maritime areas is that of the law of occupation. Nevertheless, because of the specificities …

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 …

The Legal Boundaries Of (Digital) Information Or Psychological Operations Under International Humanitarian Law, Tilman Rodenhäuser

International Law Studies

“Information operations” or “psychological operations” have long been part of armed conflicts. Among Western militaries, they are commonly understood as the employment of communication or other means to influence the views, attitudes, or behavior of adversaries or civilian populations to achieve political and military objectives. Chinese military strategy describes “psychological offense and defense” as “a combat action that uses specific information and media to influence the psychology and behavior of the target object through rational propaganda, deterrence and emotional guidance based on strategic intentions and combat missions.” Likewise, Russian military doctrine elaborates on concepts such as “psychological warfare” and on …

Prisoner Of War Status And Nationals Of A Detaining Power, W. Casey Biggerstaff, Michael N. Schmitt

International Law Studies

This article examines whether a Detaining State is obliged to recognize prisoner of war status for its own nationals under Article 4A of the 1949 Geneva Convention III. It begins with an assessment of that article from the perspective of established principles for construing treaty provisions. It then adds context to that assessment by examining relevant scholarship and State practice regarding its prescriptions before and after the Convention’s negotiation and adoption. Although it concludes that denying prisoner of war status to a national of the Detaining Power is the more persuasive interpretation of Article 4A, it concludes by highlighting the …

The Strategic Use Of Ransomware Operations As A Method Of Warfare, Jeffrey Biller

International Law Studies

This article examines the potential use and legal limitations of ransomware to achieve strategic effects in armed conflicts. Ransomware is defined here as the temporary encryption of data until some pre-condition is met to release the encryption. The article focuses on international law as applicable to a State’s use of ransomware against another State, where both are parties to an existing international armed conflict. The author finds that international humanitarian law does not currently prohibit most uses of ransomware against non-military related targets in armed conflicts. While the encryption of data may be a legal violation when it inhibits the …

The Newport Manual On The Law Of Naval Warfare, James Kraska, Raul "Pete" Pedrozo, David Letts, Wolff Heintschel Von Heinegg, Rob Mclaughlin, James Farrant, Yurika Ishii, Gurpreet S. Khurana, Koki Sato

International Law Studies

The Newport Manual on the Law of Naval Warfare is the first effort to restate the law of naval warfare as a purely lex lata exercise since 1955. It is designed to provide a practical guide for commanders and seafarers, lawyers and officials, and educators and students. In doing so, the Manual also factors in the developments in warfighting technologies in recent decades, which have significantly influenced the nature of war at sea.

Should Have Known Better? The Standard Of Knowledge For Command Responsibility In International Criminal Law, Roee Bloch

International Law Studies

The criminal doctrine of command responsibility has a rich legal history, which makes it a widely recognized, if unsettled, concept of international criminal law. This article focuses on a key element of command responsibility: the commander’s knowledge of a subordinate's crimes. This article argues that current customary law instructs to apply a standard of actual knowledge of the commander, rather than the lower standard of constructive knowledge. The article reaches this conclusion by observing the primary shaping factor of international law—State behavior. Through the example of six diverse legal systems, the article demonstrates how the approach of legislative, executive, and …

The Shadow Of Success: How International Criminal Law Has Come To Shape The Battlefield, Gabriella Blum

International Law Studies

The rise of international criminal law (ICL) has undoubtedly contributed to the development and enforcement of international humanitarian law (IHL). Yet, there are also important and oft-overlooked ways in which it has done the opposite. By labeling certain violations of the laws of war as “criminal” and setting up dedicated mechanisms for prosecution and punishment of offenders, the content, practice, and logic of ICL are displacing those of IHL. With its doctrinal precision, elaborate institutions, and the seemingly irresistible claim of political and moral priority, ICL is overshadowing the more diffuse, less institutionalized, and more difficult to enforce IHL.

But …

Russia-Ukraine Conflict: The War At Sea, Raul (Pete) Pedrozo

International Law Studies

Although much has been written about the Russia-Ukraine conflict, most writings have focused on land warfare. This article explores the conflict at sea and a host of legal issues arising from that aspect of the conflict. The article begins with a discussion of a series of events at sea that preceded the Russian invasion in 2022, including the Kerch Strait incidents and interference with freedom of navigation in the Black Sea. It then discusses multiple post-invasion legal issues involving the war at sea, including access to the Black Sea, maritime exclusion zones, naval mines, naval bombardment, unmanned maritime systems, targeting …

Manual On International Humanitarian Law For The Armed Forces Of The Russian Federation (2002)

International Law Studies

A translation of the Manual on International Humanitarian Law for the Armed Forces of the Russian Federation, 2002, by Aleksei Romanovski. This translation was originally published as Appendix 1 in Evan J. Wallach, The Law of War in the 21st Century (2017).

Some Reflections On The Threshold For International Armed Conflict And On The Application Of The Law Of Armed Conflict In Any Armed Conflict, T.D. Gill

International Law Studies

This essay discusses the threshold of application of international humanitarian law (IHL) in both international (IAC) and non-international armed conflicts (NIAC). In relation to IAC it questions whether the International Committee of the Red Cross (ICRC) “first shot” approach is the most appropriate, since it opens the way for the intensification of conflicts beyond what is necessary in relation to relatively minor armed incidents and argues that the humanitarian protection clauses of IHL should be separated from the rules governing hostilities and makes a case for the application of ad bellum considerations of necessity and proportionality to act as a …

The Legal Requirement For Command And The Future Of Autonomous Military Platforms, Rain Liivoja, Eve Massingham, Simon Mckenzie

International Law Studies

Technologically advanced armed forces extensively use platforms that can be controlled remotely and do not require an on-board crew. Increasingly, these systems have the capacity to function with some degree of autonomy. The use of autonomous functionality is not specifically prohibited or regulated by the law of armed conflict but the use of autonomous functions in military systems remains governed by the general principles and rules of international law.

One existing international law concept may constrain the use of autonomous capabilities in military vessels and aircraft. This is the notion that military units must be “under the command” of an …

International Child Law And The Settlement Of Ukraine-Russia And Other Conflicts, Diane Marie Amann

International Law Studies

The Ukraine-Russia conflict has wreaked disproportionate harms upon children. Hundreds reportedly were killed or wounded within the opening months of the conflict, thousands lost loved ones, and millions left their homes, their schools, and their communities. Yet public discussions of how to settle the conflict contain very little at all about children. This article seeks to change that dynamic. It builds on a relatively recent trend, one that situates human rights within the structure of peace negotiations, to push for particularized treatment of children’s experiences, needs, rights, and capacities in eventual negotiations. The article draws upon twenty-first century projects that …

Command Responsibility, Australian War Crimes In Afghanistan, And The Brereton Report, Douglas Guilfoyle, Joanna Kyriakakis, Melanie O’Brien

International Law Studies

This article examines the question of command responsibility for war crimes under international and Australian law, and how far such responsibility extends. It uses the results of the Brereton Report, an Australian investigation into alleged crimes committed by its special forces in Afghanistan, as its starting point. While this is very much an Australian case study, the concerns it raises should be of interest to all professional militaries. The article also provides an important case study of the implications when national legal standards adopted for war crimes prosecutions differ from the provisions of international law.

Targeting A Satellite: Contrasting Considerations Between The Jus Ad Bellum And The Jus In Bello, Hitoshi Nasu

International Law Studies

With the development and greater availability of counter-space capabilities, satellites are becoming a prime target of military threats. However, the legal assessment for the targeting of a satellite requires careful analysis because of its impacts on terrestrial activities and the potential to affect the rights and interests of third parties when their payloads are carried by the targeted satellite. With these two unique characteristics in mind, this article unravels the complexity of international legal regimes applicable to military operations conducted against a satellite by contrasting threshold legal considerations necessary for the identification and application of relevant legal requirements under the …

Cyber Peacekeeping Operations And The Regulation Of The Use Of Lethal Force, Nicholas Tsagourias, Giacomo Biggio

International Law Studies

Peacekeeping is an essential tool at the disposal of the United Nations for the maintenance of international peace and security. The growing relevance of cyber technologies presents itself as an opportunity to adapt peacekeeping to the challenges of a rapidly evolving security landscape. This article introduces the notion of "cyber-peacekeeping," defined as the incorporation and use of cyber capabilities by peacekeepers. It discusses the legal basis for cyber-peacekeeping and the foundational principles of consent, impartiality, and use of defensive force. The article examines the use of lethal force by cyber-peacekeepers under the law of armed conflict paradigm. It considers the …

Animating The U.S. War Crimes Act, Beth Van Schaack

International Law Studies

All war crimes are challenging to prosecute. Typical reasons include the technicality of some constitutive elements, the difficulties of amassing sufficient evidence, the vagaries of unreliable or unavailable witnesses, and the often-impenetrable khaki wall of silence. Adding to these challenges, the United States has erected a number of idiosyncratic structural barriers in the way in which it has incorporated the prohibitions against war crimes into its domestic legal frameworks, both military and civilian. This article addresses problems with the U.S. federal war crimes statute and proposes reforms that would (1) better conform to U.S. obligations under the Geneva Conventions and …

Revisiting Ad Bellum Proportionality: Challenging The Factors Used To Assess It, Yishai Beer

International Law Studies

Traditionally, international law has established a binary distinction between jus ad bellum and jus in bello. The former relates to the right to exercise military force. The latter regulates the conduct of adversaries engaged in an armed conflict. However, the prevailing legal approach doesn't accept this dichotomy. It wants to reduce war's hazards by applying the ad bellum rules, including the proportionality requirement, continuously throughout the conduct of armed conflict. To that end, it has established factors that define the essence of the continuing ad bellum proportionality requirement. This article challenges the near-unanimous consensus regarding these factors. It argues that …

Know Thy Enemy: The Use Of Biometrics In Military Operations And International Humanitarian Law, Marten Zwanenburg

International Law Studies

Biometrics is a technology that is increasingly being adopted by armed forces. It is the automated recognition of individuals based on their biological or behavioral characteristics. Important questions in relation to the use of this technology by armed forces concern the legal framework that governs such use. This article discusses the relationship between International Humanitarian Law (IHL) and biometrics, by focusing on a number of different activities carried out during armed conflict in which biometrics can play a role. It concludes that although IHL contains no rules that expressly regulate the use of biometrics, a number of IHL rules are …

Intelligence Sharing In Multinational Military Operations And Complicity Under International Law, Marko Milanovic

International Law Studies

This article examines the international legal framework applicable to intelligence sharing in multinational military operations, with a particular focus on complicity scenarios. It first provides a theoretical overview of the role of fault in complicity, of how intent and knowledge can be conceptualized, and of the attribution of fault to States. It then looks in detail at the rule codified in Article 16 of the International Law Commission’s Articles on State Responsibility, and argues that this rule is best understood as employing multiple modes of fault (direct and indirect intent and wilful blindness). The article also argues that international humanitarian …

Booty, Bounty, Blockade, And Prize: Time To Reevaluate The Law, Andrew Clapham

International Law Studies

This article considers the so-called belligerent rights of States in times of war. In particular it focuses on booty of war, blockade, and the capture of merchant ships and their cargo. It is suggested that, while the rules may not often be applied today, they nevertheless continue to exert a certain influence, contributing to confusion about the boundaries of the legitimate use of force and a blurring of the distinction between military objectives and civilian objects.

Considering that the UN Charter has outlawed the use of force, the article also questions why such rules concerning capture should continue to have …

The Plea Of Necessity: An Oft Overlooked Response Option To Hostile Cyber Operations, Louise Arimatsu, Michael N. Schmitt

International Law Studies

States are increasingly focused on the measures—cyber or otherwise—that they can take in response to hostile cyber operations. Although cyber operations are usually responded to with acts of “retorsion” (acts that are lawful, although unfriendly), international law recognizes other self-help mechanisms that allow for more robust responses. In the cyber context, most attention has focused on countermeasures and self-defense. Yet, both are subject to various limitations that constrain their availability.

This article examines a further option, the so-called “plea of necessity.” It allows States to respond to a hostile cyber operation when the action taken would otherwise be unlawful but …

Application Of The Due Diligence Principle To Cyber Operations, Tomohiro Mikanagi

International Law Studies

The discreet use of proxies by States renders it difficult to prove attribution to States under the existing rules of attribution. On the other hand, the due diligence principle, if applicable, does not require attribution but can lead to the invocation of State responsibility for cyber operations emanating from the territory of other States. In the Corfu Channel judgment the ICJ recognized “every State’s obligation not to allow knowingly its territory to be used for acts contrary to the rights of other States,” and UN Member States agreed that existing international law applies to cyber operations. However, the UN Members …

U.S. Recognition Of A Commander’S Duty To Punish War Crimes, Brian Finucane

International Law Studies

This article explores the United States' recognition of the doctrine of command responsibility. The doctrine has been invoked by those alleging that President Trump’s pardons of U.S. personnel convicted or accused of war crimes could amount to war crimes themselves. The article focuses on a commander’s duty to punish war crimes by his subordinates. It examines the United States’ past recognition of the duty to punish as an element of command responsibility under the law of war. The principle that a commander has an obligation to punish war crimes by his subordinates is not a progressive development of the law …
