Drawing The Cyber Baseline: The Applicability Of Existing International Law To The Governance Of Information And Communication Technologies, Dapo Akande, Antonio Coco, Talita De Souza Dias

International Law Studies

"Cyberspace" is often treated as a new domain of State activity in international legal discourse. This has led to the assumption that for international law to apply to cyber operations carried out by States or non-State actors, "cyber-specific" State practice and opinio juris must be demonstrated. This article challenges that assumption on five different bases. First, it argues that rules of general international law are generally applicable to all domains, areas, or types of State activity. In their interpretation and application to purported new domains, limitations to their scope of application cannot be presumed. Second, this article demonstrates that the …

Submarine Cable Security And International Law, Douglas R. Burnett

International Law Studies

In this article the revolution in fiber optic submarine cable communications is placed in context with the world’s growing dependence upon critical submarine cable infrastructure. Emphasis is placed on the development of international law designed to protect submarine cables and in particular those articles in the United Nations Law of the Sea Convention that foster and safeguard the freedom to lay and repair submarine cables. Special focus is applied to the status of international submarine telecommunication cables in cases of intentional actions that damage or destroy them and the State practice and customary international law that generally classifies submarine cables …

Islamist Terrorism And The Classical Islamic Law Of War, Joseph Hoelz

International Law Studies

Islamist terrorists have had a large influence on U.S. foreign and domestic policy for more than twenty years, and yet policy makers, legal practitioners, and the public know very little about what motivates these violent extremist organizations. A primary unifying principle among the various Islamist terrorist groups is their desire to return to a religiously ordered State, justified and based upon their interpretation of the Shari’a, or Islamic law. This article explores the Islamist terrorist interpretation of Shari’a law and how it generally contradicts that of mainstream Islamic scholars. The article begins with a review of the primary and secondary …

Refining Japan’S Integrative Position On The Territorial Sovereignty Of The Senkaku Islands, Atsuko Kanehara

International Law Studies

China and Japan face a tense situation in the East China Sea over conflicting sovereignty claims to the Senkaku Islands. In order to cope with the situation appropriately and precisely, Japan needs to thoroughly analyze it from the dual perspectives of the law of the sea and the law of territorial acquisition. Japan denies any existence of a dispute with China over the territorial sovereignty of the islands. The legal effects of the existence of a “dispute” need to be understood and considered by Japan when it constructs its position from the perspectives of the law of the sea and …

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 …

In Defense Of Pure Sovereignty In Cyberspace, Kevin Jon Heller

International Law Studies

States currently endorse three different positions concerning the international wrongfulness of cyber operations that penetrate computer systems located on the territory of another state but do not rise to the level of a use of force or prohibited intervention. The first position is that such low-intensity cyber operations are never wrongful, because sovereignty is a principle of international law, not a primary rule that can be independently violated. The second is that low-intensity cyber operations are always wrongful, because sovereignty is a primary rule of international law that is violated by any non-consensual penetration of a computer system located on …

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 …

China’S Container Missile Deployments Could Violate The Law Of Naval Warfare, Raul (Pete) Pedrozo

International Law Studies

China is reportedly developing long-range cruise missiles that can be fired from standard shipping containers loaded on merchant vessels. China is also converting heavy-lift civilian ships and roll-on roll-off (RORO) ferries to serve as de facto amphibious assault ships to support People’s Liberation Army (PLA) amphibious operations. While none of these activities are illegal per se, they do raise potential concerns under the law of naval warfare. Only warships can engage in offensive belligerent rights during an international armed conflict. Using merchant vessels to engage in belligerent rights would violate international law unless China first converts the vessels into warships …

Cyber Attribution And State Responsibility, William Banks

International Law Studies

We might expect international law to specifically address cyber attribution requirements due to the significance of attribution in framing the legal responsibility of States and the boundaries of responsive actions by victim States. However, there is little international law of cyber attribution, and what law there is exists largely by implication. Likewise, there is only a murky and highly contested law of State responsibility that theoretically constrains the vast majority of State-sponsored cyberattacks. Because victim States cannot engage in countermeasures unless they attribute a cyberattack to a State, attribution can serve simultaneously to constrain and empower victim States. However, the …

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 …

The International Law Of Prolonged Sieges And Blockades: Gaza As A Case Study, Eyal Benvenisti

International Law Studies

In 2007, after Hamas’ takeover of the Gaza Strip, the area was subjected to an Israeli land siege, complemented in 2009 by a sea blockade. Since then, the already-dire living conditions in the Strip have declined consistently and the area’s dependence on external aid has grown. This essay examines the duties of a military power in imposing what is effectively a years-long confinement of people and outlines a general argument for expanding the obligations of a party that imposes a prolonged siege or blockade. I consider these obligations in light of three potentially relevant legal frameworks: the law of occupation; …

Legal Advisers In The Field During Armed Conflict, Yoram Dinstein

International Law Studies

Additional Protocol I to the Geneva Conventions of 1949 requires that legal advisers be made available to military commanders, particularly during hostilities. This treaty stipulation was quite innovative in 1977, but it has achieved widespread implementation, even among non-Contracting Parties. It is noteworthy that the United States—which objects to numerous provisions of Additional Protocol I—does not dissent from the article requiring legal advisers. A study of the practice of States, made by the International Committee of the Red Cross, confirms that the norm requiring that legal advisers be made available to advise military commanders in time of armed conflict currently …

Transformative Disarmament: Crafting A Roadmap For Peace, Louise Arimatsu

International Law Studies

Notwithstanding their absence in the formal structures of power, women have engaged actively with disarmament for over a century. Their activism has been rich and complex. It is, however, not a history that is generally familiar to those outside the world of feminist activism and scholarship. This article tells the story of feminist activism and scholarship and how women have sought to overcome exclusion, marginalization, and silencing in both policy and law in pursuit of what the author describes as a transformative disarmament agenda. It is concerned not only with women’s political activism and the struggle for equal participation in …

Neutrality And Cyberspace: Bridging The Gap Between Theory And Reality, Noam Neuman

International Law Studies

While there exists a broad consensus among States that international law generally applies to the cyber domain, particular views regarding the applicability of the law of neutrality have rarely been put forward, and presently there seems to be insufficient State practice and domain-specific opinio juris in this regard. Against this backdrop, several attempts have been made throughout the years to apply certain neutrality rules to cyberspace by referring to analogies from other domains. However, this legal regime provides an emblematic example of what the introduction of traditional rules of international law, formulated with the physical domains of warfare in mind, …

Military Action To Recover Occupied Land: Lawful Self-Defense Or Prohibited Use Of Force? The 2020 Nagorno-Karabakh Conflict Revisited, Tom Ruys, Felipe Rodriguez Silvestre

International Law Studies

In September 2020, heavy fighting erupted between Armenia and Azerbaijan in and around Nagorno-Karabakh, a region of Azerbaijan long controlled by Armenia. After two months of military confrontations, a tripartite ceasefire was concluded, drastically altering the pre-existing territorial status quo.

The "Second Nagorno-Karabakh War" brings to light a fundamental question for international law on the use of force—and one that has received limited attention in legal doctrine. The question is this: when part of a State’s territory is occupied by another State for an extended period of time, can the former still invoke the right of self-defense to justify …

Protection Of Data In Armed Conflict, Robin Geiss, Henning Lahmann

International Law Studies

This article presents a novel way to conceptualize the protection of data in situations of armed conflict. Although the question of the targeting of data through adversarial military cyber operations and its implications for the qualification of such conduct under International Humanitarian Law has been on scholars’ and states’ radar for the last few years, there remain a number of misunderstandings as to how to think about the notion of “data.” Based on a number of fictional scenarios, the article clarifies the pertinent terminology and makes some expedient distinctions between various types of data. It then analyzes how existing international …

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 …

Ukraine V. The Russian Federation: Navigating Conflict Over Sovereignty Under Unclos, NilüFer Oral

International Law Studies

Following Russia’s annexation of Crimea in 2014, or according to Russia, its accession following a referendum, Ukraine brought several international cases against the Russian Federation, including two cases under Annex VII of UNCLOS: The Dispute Concerning Coastal State Rights in the Black Sea, Sea of Azov, and Kerch Strait in 2016 and The Detention of Three Ukrainian Naval Vessels in 2019. At the center of these disputes is the conflict between Ukraine and Russia over sovereignty of Crimea. Russia contested jurisdiction in all cases invoking different exceptions under UNCLOS, including the argument that the dispute concerns sovereignty over Crimea and …

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 …

Encirclement, Deprivation, And Humanity: Revising The San Remo Manual Provisions On Blockade, Tom Dannenbaum

International Law Studies

Among the most pernicious trends in contemporary armed conflict is the return of mass starvation in war, in some cases as its primary source of human suffering. This has prompted a renewed focus on the relevant rules of international humanitarian law (IHL). On some issues, there is relative consensus. On the issue of deprivation by encirclement, however, there is confusion.

Some have questioned whether the prohibition on the starvation of civilians as a method of warfare applies to encirclements at all, particularly in the naval context. Others have interpreted the prohibition vanishingly narrowly. In contrast to the more extreme of …

Israel’S Perspective On Key Legal And Practical Issues Concerning The Application Of International Law To Cyber Operations, Roy Schöndorf

International Law Studies

The speech given by the Israeli Deputy Attorney General (International Law) at the Naval War College’s event on “Disruptive Technologies and International Law” sets out, for the first time, Israel’s position on the application of international law to cyber operations. Consistent with the position taken by the vast majority of States thus far, Israel considers that international law applies to such operations. The speech stresses that questions pertaining to the identification and application of relevant legal rules remain, given the profound differences between the cyber domain and traditional domains of warfare—land, sea, and air. Therefore, in Israel’s view, a cautious …

Maritime Autonomous Surface Ships: New Possibilities—And Challenges—In Ocean Law And Policy, Joel Coito

International Law Studies

Landmark developments in autonomous vessel technology have the potential to deliver economic, environmental, and security benefits on the world’s oceans. Tempering the promise of that future is the stark reality that maritime autonomous surface ships (MASS) challenge the existing international order of the seas. This article examines the promise and perils of MASS in three areas of enduring significance to commercial vessels, naval forces, and industry regulators: search and rescue (SAR), maritime counterdrug operations, and navigational safety. This article concludes that autonomous vessel technology will lead to a superior global regime for maritime SAR operations, enhanced detection and interdiction of …

Armed Conflicts In Outer Space: Which Law Applies?, Frans G. Von Der Dunk

International Law Studies

So far, outer space has merely become involved in terrestrial armed conflicts as part of the supportive infrastructure for military activities. Unfortunately, the risk that this changes is considerably growing, and it can no longer be excluded that (armed) force will become used in outer space, either directed towards Earth or within outer space itself.

This raises serious issues in the legal context, where space law so far has been premised on the hope that armed conflicts in outer space could be avoided whereas the law of armed conflict was not required so far to deal with the use of …

Responding To Hostile Cyber Operations: The “In-Kind” Option, Michael N. Schmitt, Durward E. Johnson

International Law Studies

Facing hostile cyber operations, States are crafting responsive strategies, tactics and rules of engagement. One of the major challenges in doing so is that key aspects of the international law governing cyber responses are vague, unsettled or complex. Not surprisingly, therefore, international law is markedly absent from strategies and operational concepts. Rather, they tend to take on a practical “tit-for-tat” feel as policymakers logically view “in-kind” responses as “fair play.” For them, responding in-kind surely must be lawful notwithstanding any challenges in discerning the precise legal character of the initial hostile cyber operation.

Testing that sense, this article examines the …
