Reframing The Proportionality Principle, Michael A. Newton Jan 2018

Reframing The Proportionality Principle, Michael A. Newton

Vanderbilt Law School Faculty Publications

Proportionality functions as oneof 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 lexl . . . 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.

That frame-work, which I call the proportionality principle, is very simple: a search or seizure is reasonable if the strength of its justification is roughly proportionate to the level of intrusion associated with the police action. As the Court put it, "there is 'no ready test for determining reasonableness other than by balancing the need to search or seize against the invasion which the search or seizure entails.' In "Terry" …
