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 …

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 …

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 …

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 …

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, …

Autonomous Doctrine: Operationalizing The Law Of Armed Conflict In The Employment Of Lethal Autonomous Weapons Systems, Peter C. Combe Ii

Indeterminacy In The Law Of Armed Conflict, Adil Ahmad Haque

International Law Studies

Controversy and confusion pervade the law of armed conflict. Its most basic rules may seem ambiguous, vague, incomplete, or inconsistent. The prevailing view of customary international law confronts serious problems, in principle and in practice, when applied to the customary law of armed conflict. Legal indeterminacy, in its different forms, might be reduced or resolved in light of the object and purpose of the law of armed conflict, or by taking into account other relevant rules of international law. Unfortunately, the purpose of the law of armed conflict is itself the subject of deep disagreement. So is the relationship between …

Medical Care In Urban Conflict, Kenneth Watkin

International Law Studies

The potential for urban violence is increasing as the world population continues to migrate towards cities. Recent examples of urban warfare with insurgent groups has occurred in Damascus, Mosul, Raqqa, Marawi, Ramadi, and Fallujah, although non-State actor conflict covers a wide range of violence from ordinary crime, to terrorism and transnational crime, to near conventional conflict. Further, transnational terrorist groups have sought to extend the conflict into countries seen as the “far enemy.” A key issue is determining if an armed conflict is in existence so that the protective focus of international humanitarian law regarding the provision of medical care …

Humanitarian Logic And The Law Of Siege: A Study Of The Oxford Guidance On Relief Actions, Sean Watts

International Law Studies

In terms of human suffering, few military operations have rivaled sieges and comparably harsh legal regimes have governed them. At a time when legal vindication of humanitarian interests in armed conflict is ascendant, conventional accounts of the law of war governing humanitarian relief may seem out of step, plagued with glaring gaps in humanitarian logic. In 2016, Oxford University professors published a United Nations-commissioned legal study—the Oxford Guidance on the Law Relating to Humanitarian Relief Operations in Situations of Armed Conflict. The Guidance contends that during armed conflict international law prohibits belligerents from arbitrarily denying offers of humanitarian relief …

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 …

Event Horizon: Examining Military And Weaponization Issues In Space By Utilizing The Outer Space Treaty And The Law Of Armed Conflict, Ryan M. Esparza

Journal of Air Law and Commerce

This article takes the position that any lingering ambiguities surrounding the militarization and weaponization of outer space should be analyzed via the joint scope of the Outer Space Treaty and the Law of Armed Conflict. This article pulls key provisions from Additional Protocol I to the Geneva Conventions because of Additional Protocol I’s application in international conflicts and affirmation of the four Geneva Conventions. After an examination of key Additional Protocol I provisions and their application to space, this article conducts a joint analysis of the Outer Space Treaty and the Law of Armed Conflict. This joint analysis examines three …

Special Issue: The Law Of Armed Conflict, Ben Wahlhaus Major, International Law Department, Hannah Lidicker Editor In Chief

Vanderbilt Journal of Transnational Law

Few areas of international law are as consequential as the Law of Armed Conflict (LOAC). At its very core, it entails an endeavor to regulate death and destruction both for those who participate in a conflict and for those who are simply affected by the conflict.

LOAC is also of continued relevance. The number of armed conflicts around the world does not seem to be on the wane, and thus there is no shortage of situations in which LOAC remains applicable.

Just as the law retains its consequence and relevance, the study of LOAC retains its importance. Old questions warrant …

Examining The Role Of Law Of War Training In International Criminal Accountability, Laurie R. Blank

Utah Law Review

Training and dissemination of the fundamental rules and principles of law of armed conflict (LOAC) is the first step in any process to ensure lawful military operations. A soldier, a military unit, an entire military must know the rules and parameters for appropriate, lawful and effective action during armed conflict. In the same manner, accountability for violations of LOAC — whether individual criminal accountability or state responsibility — is an equally essential tool for enforcing the law. Exploring the intersection between these two endpoints of the spectrum of LOAC implementation highlights how training and accountability can actually work together to …

Interpretation Catalysts In Cyberspace, Rebecca Ingber

Faculty Scholarship

The cybersphere offers a rich space from which to explore the development of international law in a compressed time frame. This piece examines the soft law process over the last decade of the two Tallinn Manuals – handbooks on the international law of cyber warfare and cyber operations – as a valuable lens through which to witness the effects of “interpretation catalysts” on the evolution of international law. In prior work, I identified the concept of interpretation catalysts – discrete triggers for legal interpretation – and their influence on the path that legal evolution takes, including by compelling a decision-making …

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 …

Applying The Law Of Proportionality To Cyber Conflict: Suggestions For Practitioners, Eric Boylan

Vanderbilt Journal of Transnational Law

This Note examines the applicability of the law of armed conflict, and particularly the concept of proportionality, to cyber attacks. After exploring deviations in terminology that may lead to confusion in the field, it considers the difficulties associated with applying an area of law first implemented in the post-World War II era to technologies that have only become vitally important in recent years. Delving into some of the facets of cyber technology that make it unique as a potential battleground, this Note examines why those qualities make the law of proportionality particularly difficult to apply. Acknowledging that the law of …

Should The Best Offenses Ever Be A Good Defense: The Public Authority To Use Force In Millitary Operations: Recalibrating The Use Of Force Rules In The Standing Rules Of Engagement, Gary Corn

Articles in Law Reviews & Other Academic Journals

The Chairman of the Joint Chiefs of Staff's Standing Rules of Engagement/StandingRules for the Use of Force (SROE/SRUF)for U.S. Forces provides strategic guidance to the armed forces on the authority to use force during all military operations. The standing self-defense rules in the SROE for national, unit, and individual self-defense form the core of these use-of-force authorities. The SROE self-defense rules are incorrectly built on a unitary jus ad bellum framework, legally inapplicable below the level of national self-defense. Coupled with the pressures of sustained counter-insurgency operations, this misalignment of individual and unit self-defense authorities has led to a conflation …

Detention Under The Law Of Armed Conflict, Chris Jenks

Faculty Journal Articles and Book Chapters

Despite recent hard-earned experience during international and non-international armed conflicts in places like Afghanistan and Iraq, and in peacekeeping missions around the world, the international community continues to struggle practically and conceptually with detention of belligerents. The struggle includes questions ranging from when individuals may be detained and for how long, to determining the applicable legal regime. While this myriad of issues is vexing, they are neither as new, nor the applicable law as lacking, as has been argued.

This chapter takes a pragmatic approach to detention and suggests that the 1949 Geneva Conventions and the 1977 Additional Protocols, outmoded …

Right To Act: United States Legal Basis Under The Law Of Armed Conflict To Pursue The Islamic State In Syria, Samantha Arrington Sliney

University of Miami National Security & Armed Conflict Law Review

Shortly after the beginning of the Syrian Civil War, the Islamic terror group ISIS captured the world’s attention with their rapid advance through Iraq and acts of severe brutality. In short order, the group captured large swaths of territory in Iraq and Syria and declared the formation of an Islamic State. With the integrity of Iraq in the balance, the United States committed to taking military action against ISIS but quickly discovered that as pressure was put on ISIS in Iraq they retreated into Syrian lands, where U.S. warplanes could not go.

This article explores the legal justifications for the …

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.

War, Law, And The Oft Overlooked Value Of Process As A Precautionary Measure, Geoffrey S. Corn

Pepperdine Law Review

Never in recent memory has the relationship between law and war been so central to strategic legitimacy. This has resulted in both positive evolutions of the law of armed conflict (LOAC) and a remarkable increase in interest, understanding, and analysis of this law. No state, or even non-state group, is immune from the increasingly informed critique of its planning and execution of military operations and the quite proper demand that its military personnel comply with LOAC obligations. Central to the regulation of hostilities are the core LOAC principles of distinction and discrimination. Distinction mandates restricting deliberate attack to only those …

The Boundless War: Challenging The Notion Of A Global Armed Conflict Against Al-Qaeda And Its Affiliates, Andrew Beshai

Loyola of Los Angeles Law Review

The U.S. military response to the 9/11 attacks has expanded into a “global war” without a definite geographic scope. Both the Bush and Obama administrations have executed attacks in several countries including Somalia, Afghanistan, Pakistan, and Yemen under the “global war” paradigm. This Article challenges the concept of a global armed conflict, instead favoring the “epicenter-of-hostilities” framework for determining the legality of military action against Al-Qaeda, the Taliban, and other terrorist groups. This approach, rooted in established international law, measures the existence of specific criteria in each nation where hostile forces are present to determine if an armed conflict in …

The Ndaa, Aumf, And Citizens Detained Away From The Theater Of War: Sounding A Clarion Call For A Clear Statement Rule, Diana Cho

Loyola of Los Angeles Law Review

In the armed conflict resulting from the September 11 attacks, the executive authority to order the indefinite detention of citizens captured away from the theater of war is an issue of foreign and domestic significance. The relevant law of armed conflict provisions relevant to conflicts that are international or non-international in nature, however, do not fully address this issue. Congress also intentionally left the question of administrative orders of citizen detainment unresolved in a controversial provision of the 2012 version of the annually-enacted National Defense Authorization Act. While plaintiffs in Hedges v. Obama sought to challenge the enforceability of NDAA’s …

Silencing The Call To Arms: A Shift Away From Cyber Attacks As Warfare, Ryan Patterson

Loyola of Los Angeles Law Review

Cyberspace has developed into an indispensable aspect of modern society, but not without risk. Cyber attacks have increased in frequency, with many states declaring cyber operations a priority in what has been called the newest domain of warfare. But what rules govern? The Tallinn Manual on the International Law Applicable to Cyber Warfare suggests existent laws of war are sufficient to govern cyber activities; however, the Tallinn Manual ignores fundamental problems and unique differences between cyber attacks and kinetic attacks. This Article argues that several crucial impediments frustrate placing cyber attacks within the current umbra of warfare, chiefly the problems …

A Military Justice Solution In Search Of A Problem: A Response To Vladeck, Geoffrey S. Corn, Chris Jenks

Faculty Journal Articles and Book Chapters

In “Military Courts and Article III,” law professor Steve Vladeck proposes a wholesale replacement of the foundation upon which court-martial jurisdiction has stood since the inception of the United States. In an effort to provide a unifying theory grounded in international law, Professor Vladeck fails to properly distinguish the jurisdiction established by Congress to regulate the armed forces from the jurisdiction established to punish violations of the laws of war. This conflation yields confusion about military jurisdiction which ripples throughout the theory. Our response, which centers on courts-martial, argues that Professor Vladeck has offered a solution in search of a …

Non-State Armed Groups And The Role Of Transnational Criminal Law During Armed Conflict, Christopher L. Blakesley, Dan E. Stigall

Scholarly Works

With the ascendance of the terrorist group known as the Islamic State of Iraq and Syria (ISIS), the international community has struggled to adapt to the new international security context. Among the challenges that are currently being confronted are questions relating to how states may effectively facilitate international cooperation to counter ISIS (especially among countries in the Middle East and North Africa). Within this context, guidance from the United Nations on international cooperation posits that “[t]he universal counter-terrorism conventions and protocols do not apply in situations of armed conflict” – a legal position that would serve to stymie important cooperative …

Cyber Espionage Or Cyber War?: International Law, Domestic Law, And Self-Protective Measures, Christopher S. Yoo

All Faculty Scholarship

Scholars have spent considerable effort determining how the law of war (particularly jus ad bellum and jus in bello) applies to cyber conflicts, epitomized by the Tallinn Manual on the International Law Applicable to Cyber Warfare. Many prominent cyber operations fall outside the law of war, including the surveillance programs that Edward Snowden has alleged were conducted by the National Security Agency, the distributed denial of service attacks launched against Estonia and Georgia in 2007 and 2008, the 2008 Stuxnet virus designed to hinder the Iranian nuclear program, and the unrestricted cyber warfare described in the 1999 book by …
