Abstract
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.

Notes
I leave aside here the more recently emphasised fields of justice in ending wars (jus ex bello) and justice following war (jus post bellum).
For a useful survey and comparison of different accounts of jus ad bellum, see Toner (2010).
The criterion is also variously referred to in the literature as the ‘right’, ‘proper’, ‘competent’ or ‘sovereign’ authority requirement.
For an overview of the equality thesis and the debate surrounding it, see Rodin and Shue (2008a).
This interpretation is particularly reinforced on an orthodox approach to just war theory, which hold that these two fields are independent of one another.
See Toner (2010).
On the distinction between external and internal constraints on the resort to war, see Buchanan (1999).
For example, the few discussions of applying the authority criterion in practice predominantly focus on the extent to which the President of the United States has the legal authority to take the nation to war without congressional approval. Christopher (2004: 87–88), Orend (2000: 97), Regan (1996: Ch.2).
A structurally similar, though substantively distinct, version of the argument that I set out in the next three sections has also been suggested, albeit quite briefly, by Christopher Finlay (2010: Section III). My goal in this paper is to develop a more detailed and precise version of the argument, and to then explore its wider implications for just war theorising.
For a useful collection of papers on this topic, see Rodin and Shue (2008b).
See Walzer (2006a: 144–145).
This problem is raised in McMahan (2009: 52).
In addition, Asa Kasher and Amos Yadlin have argued that entering military service does not alter the normative situation between a citizen and their state, so that the state is not permitted to impose additional risks on their military personnel simply in virtue of their combatant status. Kasher and Yadlin (2005: 17).
In addition to the Equality Thesis, the orthodox principle of non-combatant immunity has also been shown to be difficult to reconcile with our more general views about permissible killing (Frowe 2014: Chs. 6–8). If so, this reveals that the standard norms of conduct in war may also be more restrictive than those that govern harming in other contexts.
The Discontinuity Thesis is similar to a view Seth Lazar labels ‘exceptionalism’. See Lazar (2014).
For example, both Henry Shue and Michael Walzer each, independently, endorse a version of the Discontinuity Thesis (Shue 2008; Walzer 2006b). Judith Jarvis Thomson and Frances Kamm have also, independently, suggested versions of it, albeit without explicit endorsement (Thomson 1991: 297; Kamm 2012: 27).
Neff (2005: 13–20). Neff does note that a small minority of cultures, such as the Innuit, do seem to lack a strong distinction between war and other forms of violence.
I offer support for this claim in the section entitled “Classical Just War Theory and the Authority Criterion”.
For a book length discussion of this contrast, see Fiala (2010).
Jeff McMahan also notes this requirement (McMahan 2009: 31).
As George Fletcher puts it, “not every shootout at the OK Coral qualifies.” (Fletcher 2002: 3).
David Luban raises a similar problem regarding demarcating the boundary between the application of human rights law and the humanitarian law of armed conflict (Luban 2008: 276–280).
Helen Frowe makes a similar point, suggesting that one function of the authority criterion is to define what counts as war (Frowe 2011: 59, 2014: 157–158). However, Frowe does not provide an account of why it morally matters that war be defined in such terms. It is this missing element that I aim to provide in this paper.
Moseley does not present this claim as an interpretation of the role of the authority criterion.
I borrow the notion of ‘logical priority’ from Anthony Coates, who briefly suggests a similar interpretation of the authority criterion to my own in the context of his discussion of terrorism (Coates 1997: 123–124). Coates points out that it is problematic to understand the wrongfulness of terrorism in terms of violations of the just war principle of non-combatant immunity, because non-combatants immunity is a war-specific notion, implying that terrorists are engaged in war and are entitled to moral evaluation under the norms of just war theory. (For a similar point, see Goodin 2006: Ch.1). After raising this worry, Coates then concludes “that if any criterion of war merits greater application to terrorism than any other…it is the logically prior principle of legitimate authority.” (124). However, Coates does not provide an explicit account of why invoking the authority criterion is meant to resolve the worry, or why the criterion is ‘logically prior’ in the manner claimed. Moreover, in the majority of his discussion of the authority criterion (125–145) Coates retreats from the more expansive interpretation that he initially suggests, reverting instead to the standard, ad bellum interpretation. In this paper I aim to have provided the necessary arguments for expanding the role of the authority criterion in the manner that Coates alludes to. Furthermore, if successful, my arguments show that that this expansion is not necessitated merely by specific practical worries about terrorism. Rather, the criterion is required to play this additional role for more theoretical reasons, in order to prevent just war theory from running into a fatal problem of moral indeterminacy and incoherence. If correct, this shows that Coates’ and Goodin’s worry about excluding terrorism from just war evaluation is a symptom of a much more general issue.
For example, the Correlates of War Project, which provides a major source of data for the empirical study of warfare, classifies wars as sustained combat, involving organised forces, resulting in at least 1000 combat deaths per 12-month period (Sarkees 2010).
The formulation here is intended to allow for the possibility that in bello permissions may apply asymmetrically to opposing parties in an armed conflict, since one party may satisfy the authority criterion (and so be subject to norms of jus in bello) whereas the opposing party may not (and so be subject to ordinary norms of interpersonal harming.) For example, in the case of a recognised state engaging in armed conflict with a non-state entity, such as a terrorist organisation. Term this the unilateral reading of the revised authority criterion. By contrast, the quote from Orend’s suggests an alternative bilateral reading, which requires the authority criterion to be satisfied by both belligerents in order for war-specific norms to apply to either. Both readings seem defensible, though my intuitions favour the unilateral reading. But for our purposes we need not settle the matter here. The main claim that I defend and elaborate upon in this in this paper—that fighting on behalf of a legitimate authority is a necessary condition for evaluation under the norms of jus in bello—is consistent with either reading. (The extent to which it approaches a sufficient condition does vary depending on the reading.) In addition, it is worth pointing out that, on either reading, the fact that a non-state entity fails to qualify as an authority need not entail that it is unjustified in fighting against a state (since its violence could be justified in terms of ordinary norms of interpersonal harming, such as self-defence). Nor does a non-state entity’s failure to qualify entail that its state opponent is justified in fighting against it, since such measures would remain subject jus ad bellum requirements. Thanks to an anonymous reviewer for pressing me to clarify these points.
See, for example, Begby et al. (2012: 331). More broadly, proponents of the ‘new wars’ thesis, such as Mary Kaldor, argue that the diversity of actors involved in modern armed conflict poses deep challenges to normative international political theory more generally (Kaldor 2007). For proposals as to how the norms of war may be adapted to apply to modern war, see Gilbert (2003), Gross (2009) and Kasher and Yadlin (2005).
See Heinze and Steele (2009).
Fotion does not explicitly endorse an orthodox conception of jus in bello. However, such a commitment can be inferred from what he does say on the topic. For example, he writes “it is easy to separate that part of a theory of exception having to do with starting a war (justice of the war) and the protracted period of time that follows once the war is started (justice in the war).” (2007: 21). Fotion also endorses a view of the in bello discrimination and proportionality requirements that are equally satisfiable by combatants who participate in just and unjust wars (2007: 21–22). Thus, taken together, it seems fair to attribute to Fotion a commitment to the orthodox Equality Thesis.
The criterion remains applicable to state actors engaged in armed conflict with non-state actors under JWT-I. Fotion also relaxes the criterion of reasonable prospect of success in JWT-I (Fotion 2007: 120).
See Reichberg (2013).
See O’Donovan (2003: 22).
Thompson (1996: 677–679). George Fletcher points out that a successful invocation of the medieval common law defence of se denfendendo resulted only in the defendant’s avoidance of the punishment of execution, while conceding the wrongfulness of the act. The successful defendant was still required to give up property to the crown by way of recompense for the homicide. He notes, “Until the Statute of Henry VIII, passed in 1532…there was no theory of self-defense that rendered a killing fully lawful, justifiable and therefore free of the taint that affected excusable homicide.” (Fletcher 1990: 171).
This thought is endorsed by Elizabeth Anscombe, the most influential recent proponent of a classical conception of just war, who writes that “The right to attack with a view to killing is something that belongs only to rulers and those they command to do it” (Anscombe 1981: 53) (emphasis added). Michael Thompson makes a similar point, arguing that “premodern practice,…restricted justified killing to that legitimately performed by agents of the state.” (Thompson 1996: 678).
James Turner Johnson makes a similar point, noting that within classical just war theory “There is a fundamental moral difference between the use of the sword by one in sovereign authority or on his behalf and the use of the sword by a private individual. The former may wage bellum, which is the use of the sword on behalf of the common good; the latter may not.” (Johnson 2003: 9–10).
Kutz suggests that he is committed to this interpretation (2005: 179).
On this point, see Lichtenberg (2008).
See Lazar (2013).
See Estlund (2007).
I discuss this objection in more detail in an unpublished paper entitled ‘Liability, Community, and Just Conduct in War.
