Since its earliest incarnations, just war theory has included the requirement that war must be initiated and waged by a legitimate authority. However, while recent years have witnessed a remarkable resurgence in interest in just war theory, the authority criterion is largely absent from contemporary discussions. In this paper I aim to show that this is an oversight worth rectifying, by arguing that the authority criterion plays a much more important role within just war theorising than is commonly supposed. As (...) standardly understood, the authority criterion provides a necessary condition for the justification of the resort to war, but has no bearing on the question of permissible conduct in war. In opposition, I argue for an alternative interpretation of the criterion, which attributes to it a fundamental role in assessing this latter question. With this revised interpretation in place, I then demonstrate its advantages by applying it to the practical issue of armed conflicts that are initiated and fought by non-traditional belligerents. While several theorists have recognised that this common feature of modern armed conflict poses a challenge to mainstream just war theory in general—and to the authority criterion in particular—I argue that existing discussions frequently misconstrue the nature of the challenge, since they assume the standard interpretation of the authority requirement and its role within the theory. I then show that the revised interpretation provides a clearer account of both the challenge posed by non-traditional belligerency and the kind of response that it requires. (shrink)

What, if anything, is problematic about gentrification? This article addresses this question from the perspective of normative political theory. We argue that gentrification is problematic insofar as it involves a violation of city-dwellers’ occupancy rights. We distinguish these rights from other forms of territorial rights and discuss the different implications of the argument for urban governance. If we agree on the ultimate importance of being able to pursue one’s located life plans, the argument goes, we must also agree on limiting (...) the impact of gentrification on peoples’ lives. Limiting gentrification’s impact, however, does not entail halting processes of gentrification once and for all. (shrink)

War has changed so much that it barely resembles the paradigmatic cases of armed conflict that just war theories and international humanitarian law seemed to have had in mind even a few decades ago. The changing character of war includes not only the use of new technology such as drones, but probably more problematically the changing temporal and spatial scope of war and the changing character of actors in war. These changes give rise to worries about what counts as war (...) and thus what norms to use in evaluating a particular conflict. In this paper, I develop an argument that the changing character of war gives us reasons to take reductionist revisions of just war theory seriously. By reductionist theories of war I mean those revisions within the just war tradition that suggest that we can use ordinary peacetime interpersonal analyses of moral responsibility and liability to harm to decide what justice requires in times of war.

War should be understood as an actual, intentional and widespread armed conflict between political communities. Thus, fisticuffs between individual persons do not count as a war, nor does a gang fight, nor does a feud on the order of the Hatfields versus the McCoys. War is a phenomenon which occurs only between political communities, defined as those entities which either are states or intend to become states (in order to allow for civil war). Classical war is international war, a war (...) between different states, like the two World Wars. But just as frequent is war within a state between rival groups or communities, like the American Civil War. Certain political pressure groups, like terrorist organizations, might also be considered “political communities,” in that they are associations of people with a political purpose and, indeed, many of them aspire to statehood or to influence the development of statehood in certain lands.
