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 …

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 …

Confronting Space Debris Through The Regime Evolution Approach, Gershon Hasin

International Law Studies

This article examines the complex policy problem of space debris and elaborates a proposal for a bottom-up cooperative regime for its mitigation. While debris proliferation generates costs and threatens the safety of personnel and equipment, this policy problem is compounded by the realization that debris constitutes a by-product of desirable space activities which facilitate national progress and domestic increases in values. It is further complicated by increased private participation, conflicting interests of participants, and a global order susceptible to outlier behavior.

Scholars attempting to tackle this policy problem have failed to appreciate the complex legislative process through which international rules …

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 …

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 …

Is A South China Sea Code Of Conduct Viable?, Raul (Pete) Pedrozo

International Law Studies

For over twenty years, the People’s Republic of China (PRC) has stonewalled efforts by the Association of Southeast Asian Nations (ASEAN) to negotiate a binding Code of Conduct that would form the basis for a peaceful and durable solution to the territorial and maritime disputes in the South China Sea (SCS). At the same time, the PRC engaged in a series of malign activities, to include the militarization of several reclaimed artificial islands, that have forever changed the landscape and status quo of the SCS. In 2020, the PRC unexpectedly called on ASEAN to resume the negotiations as soon as …

Enclosure Of The Oceans Versus The Common Heritage Of Mankind: The Inherent Tension Between The Continental Shelf Beyond 200 Nautical Miles And The Area, Michael W. Lodge

International Law Studies

The 1982 United Nations Convention on the Law of the Sea (UNCLOS) is a major achievement of diplomacy in the late twentieth century and is rightly regarded as the “constitution for the ocean.” UNCLOS has withstood the test of time and has demonstrated its flexibility and adaptability to changing circumstances. Notwithstanding, there is an underlying tension at the heart of UNCLOS as it tries to reconcile two fundamentally different approaches—the exclusivity of coastal State jurisdiction versus the international character and shared space of the Area beyond national jurisdiction. As the search for mineral deposits in the Area intensifies, and as …

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, …

Foreign Cyber Interference In Elections, Michael N. Schmitt

International Law Studies

In the 2020 U.S. elections, Russia authorized and conducted influence operations designed to support former President Trump, although it did not attempt to alter any technical aspect of the voting process. Russia was not alone. Iran mounted a multi-pronged covert influence campaign intended to undercut Trump’s reelection prospects, while other foreign actors–like Lebanese Hizballah, Cuba, and Venezuela–also tried to influence the election. Interestingly, China did not conduct operations designed to alter the outcome, although it did consider doing so. The phenomenon of election meddling, however, extends well beyond the United States to such countries as Austria, Estonia, France, Germany, Hungary, …

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 …

U.S. Recognition Of Japanese Sovereignty Over The Senkaku Islands, Raul (Pete) Pedrozo

International Law Studies

Every U.S. administration from Truman to Kennedy recognized Japanese residual sovereignty over the Senkaku Islands. U.S. policy changed, however, to one of neutrality under the Nixon administration during the negotiations of the Okinawa Reversion Treaty. The change in policy was not based on a belief that Japan did not retain sovereignty over the islands, but rather was done to appease the Republic of China over its impending expulsion from the United Nations and to break an impasse of the ongoing textile negotiations with Taipei. The administration’s overtures to China, culminating in Nixon’s visit to China contributed to the decision. Since …

The “External Element” Of The Obligation To Ensure Respect For The Geneva Conventions: A Matter Of Treaty Interpretation, Marten Zwanenburg

International Law Studies

In Common Article 1 of the 1949 Geneva Conventions, States Parties undertake to “respect and ensure respect” for the Conventions. This article focuses on the question whether an interpretation of that provision leads to the conclusion that it contains an external element. The term “External element” refers to an obligation for States to ensure respect for the Conventions not only internally (i.e., by their nationals as a whole), but also by other States, and possibly even by organized armed groups involved in extraterritorial non-international armed conflicts. The article applies the rules of treaty interpretation, as codified in Articles 31 – …

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 …

Maritime Police Law Of The People’S Republic Of China, Raul (Pete) Pedrozo

International Law Studies

China’s new Maritime Police Law (MPL) purports to regulate the duties of China’s maritime police agencies, including the China Coast Guard, and safeguard China’s sovereignty, security, and rights and interest. The MPL has potentially far-reaching application, as China claims extensive maritime areas off its mainland and in the South China Sea. This expansive application of maritime law enforcement jurisdiction is problematic given that most of China’s maritime claims are inconsistent with international law. To the extent that the MPL purports to assert jurisdiction over foreign flagged vessels in disputed areas or on the high seas, it contravenes international law. Numerous …

Nuclear Terrorism: Statutory Shortcomings And Prosecutorial Opportunities, Rohan Mishra

International Law Studies

In 2016, President Barack Obama warned that “[t]he danger of a terrorist group obtaining and using a nuclear weapon is one of the greatest threats to global security.” Thus far, however, U.S. and international efforts to address nuclear terrorism have faced a fundamental dilemma: While the importance of preventing this threat is unquestioned, there has been limited opportunity or need to conduct prosecutions that hinge on nuclear terrorism charges. This dilemma reflects the current piecemeal approach to nuclear terrorism, which prioritizes policies that address the “back-end” risk of nuclear terrorism (i.e., the detonation of nuclear weapons or attack of nuclear …

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 …

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 …

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 …

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 …

Questions Relating To The Continental Shelf Beyond 200 Nautical Miles: Delimitation, Delineation, And Revenue Sharing, Helmut Tuerk

International Law Studies

Article 76 UNCLOS provides a new definition of the legal continental shelf, which grants coastal States sovereign rights and jurisdiction extending to the outer edge of the continental margin. The broad-shelf States had to make two compromises to have that provision accepted, that is revenue-sharing for the benefit of the international community with respect to the continental shelf beyond 200 nautical miles, enshrined in Article 82 UNCLOS, and the delineation of the outer limits of the continental shelf beyond that distance “on the basis of” recommendations by the CLCS, in order that these limits may become “final and binding.” In …

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 …

The Value And Viability Of The South China Sea Arbitration Ruling: The U.S. Perspective 2016–2020, Jonathan G. Odom

International Law Studies

In 2016, an international arbitral tribunal issued a landmark ruling addressing a number of international law issues in the South China Sea. Yet more than four years have passed since that ruling, and the South China Sea situation remains unresolved. The South China Sea arbitration ruling was a positive step in applying a rules-based approach to framing, managing and resolving some of these international disputes. Thus, the international community should reflect upon the value and viability of the arbitral tribunal’s ruling, to include viewing it from the current perspectives of individual States. This article provides a more detailed review and …

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 …
