Some Reflections On The "Incidental Harm" Side Of Proportionality Assessments, Emanuela-Chiara Gillard

Vanderbilt Journal of Transnational Law

The rule on proportionality represents the most apparent manifestation of the balance between military necessity and considerations of humanity that underpins IHL. As military operations are taking place in densely populated areas with increasing frequency, the rule's significance for the protection of civilians has become even more key. It is of central relevance to the current discussions on the use of explosive weapons in populated areas.

Determining what falls into the two "sides" of the proportionality assessment as clearly as possible is essential to the proper application of the rule in practice. The expected "military advantage side" of the equation …

Proportionality Under International Humanitarian Law: The "Reasonable Military Commander" Standard And Reverberating Effects, Ian Henderson, Kate Reece

Vanderbilt Journal of Transnational Law

The principle of proportionality protects civilians and civilian objects against expected incidental harm from an attack that is excessive to the military advantage anticipated from the attack. However, despite its status as a fundamental norm of international humanitarian law (IHL), key terms are not defined in relevant treaties nor do they benefit from critical judicial explanation. This has caused challenges for both academics and military commanders alike in explaining and applying the test for proportionality.

The Article expands upon two points that were raised and generated interesting discussion at The Second Israel Defense Forces International Conference on the Law of …

Four Comments On The Application Of Proportionality Under The Law Of Armed Conflict, Lieutenant Colonel Roni Katzir

Vanderbilt Journal of Transnational Law

The existence of the principle of proportionality as a norm is undisputed, and military commanders in armed conflicts around the world apply it continuously. As the principle is formulated in general terms--prohibiting attacks that may be expected to cause incidental loss of civilian life, injury to civilians, or damage to civilian objects, or a combination thereof, that would be excessive in relation to the military advantage anticipated--it is also clear that interpreting and applying the different elements of the principle is no simple task.

This Article shall consider four select issues regarding different elements of the principle of proportionality.

Reframing The Proportionality Principle, Michael A. Newton

Vanderbilt Journal of Transnational Law

Proportionality functions as one of the most important legal constraints applicable to the conduct of hostilities. In that context, this short essay discusses the commonly encountered misapplications of Cicero's classic sentiment that "salus populwe supremus est lex...silent enim leges inter armes." Rather than serving as a necessary basis for a positive articulation of lawful force as an exception to the norm, jus in bello proportionality delineates the outer boundaries of the commander's appropriate discretion. The mere invocation of jus in bello proportionality cannot become an effective extension of asymmetric combat power by artificially crippling combatant capabilities. This essay ends by …

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 …
