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.
