Situating the accountability of the UN Security Council: Between liberal-legal and political ‘styles’ of global constitutionalism?

‘Accountability’ is the international legal term du jour. The concept is omnipresent in contemporary discussions about the UN Security Council in particular. From the lack of due process guarantees for individuals implicated in its counter-terrorism sanctions regime, to the (in)compatibility of Council authorized uses of force with international human rights and humanitarian law, no aspect of the Council’s recent practice has been immune froman accountability critique.Driven by the context inwhich it has emerged, the turn to accountability is seemingly prompted by a felt desire among international lawyers to constrain the arbitrary use of the Council’s considerable powers. However, beyond this felt desire, the concept lacks a robust theoretical foregrounding, both on its own terms and in relation to existential developments in international law. In an attempt to remedy this, this article situates the turn to accountability as a product of the broader turn to ‘constitutionalist’ thinking in international law. Specifically, it suggests that mainstream approaches resonate with a particular ‘liberal-legalist style’ of global constitutionalism. From both an etymological and epistemological perspective, however, I argue that this prevailing style offers an incomplete sense of accountability. The article introduces the dichotomy of ‘liberal-legal’ and more overtly ‘political’ styles of global constitutionalism as a heuristic device in order to offer a broader conception of accountability in the Security Council context. Political constitutionalism, I believe, offers important insights that will allow us to perceive and critique the Security Council in new ways.


I. Introduction
On 12 September 2018, the UN General Assembly met to consider the UN Security Council's annual report on measures taken under its primary responsibility for the maintenance of international peace and security. The Assembly does not typically engage closely with this report. In the same meeting in 2017, it was noted that the debate had become a 'ritual', 1 representing 'one more formality in a long list of formalities'. 2 While only two states took to the floor, this time the thrust of their respective interventions was substantively different. Gholamali Khoshroo, the representative of Iran, took issue in strong terms with Security Council interventions into a state's 'internal affairs, interference in which is explicitly prohibited by the Charter'. 3 Wei'en John Khoo, representing Singapore, adopted a similarly critical posture. He suggested that 'the sovereign rights of States, as well as human rights, have been seriously violated'. 4 He concluded, 'if unchecked, this alarming trend will further tarnish the credibility of the Organization and this Council, eroding the rule of law and leading to international disorder'. 5 Crucially, the speakers couched their critique using exactly the same frame of reference, separately noting that the Security Council must be more 'accountable'. 6 For member states to explicitly suggest that the primary political organ of the United Nations should be accountable for its actions represents a monumental shift in the manner in which this term is typically used. For ten years between 2003 and 2013, the question of 'the promotion and strengthening of the rule of law in the maintenance of international peace and security' was a standing item on the Council's agenda. In its final statement on the matter, the Council stressed that the importance of the 'fight against impunity … to ensure accountability for genocide, crimes against humanity, war crimes and other egregious crimes '. 7 This shows that, if anything, the Council sees itself primarily as a promoter of the accountability of others, whether states, non-state groups or individuals. As evidenced by this more recent debate, it seems that now the shoe is on the other foot. The accountability of the Council itself is under the spotlight.
This shift resonates with a broader move in international legal discourse. It is difficult to think of a single issue of contemporary significance to international lawyers that a recent 'turn to accountability' has overlooked, but this is especially true when it comes to international organizations. 8 The such, in the literature there is a tendency to define accountability in a rather reductive manner. In the Kelsenian, positivist tradition, which remains the 'lingua franca of international lawyers', 14 accountability tends to stand as a synonym for the notion of control, specifically legal control. It is associated with attempts to constrain the Council by identifying binding legal obligations provided by the Charter as the Council's lex specialis or by general international law (as lex generalis) and ensuring that these obligations are enforced. 15 This article is prompted by a doctrinal and conceptual scepticism about the current trajectory of the debate. On a doctrinal level, such accounts tend to dramatically overplay the level of agreement regarding what rules actually bind the Council and, if they are binding, how they came to be. On a conceptual level, by placing disproportionate attention on the notion of 'holding to account', it is difficult to identify a line of demarcation between accountability and the doctrine of international legal responsibility. For the international lawyer, this makes some sense. International responsibility has a particular grip on international legal imaginations. Yet one question lingers: what space does this leave for accountability as a stand-alone concept?
To recover space for accountability on its own termsespecially a version of accountability that is applicable to the Security Councilit is necessary to think about how and why this reductive understanding has developed. This article suggests that one way to read the turn to accountability is as a product of the emergence of an explicitly constitutionalist vernacular in international law. The general association between the concepts of 'accountability' and 'constitutionalism' is often taken for granted. On a base level, 'accountability talk' is a perennial feature of everyday constitutional law and politics. 16 However, this article argues that the relationship between the turn to 14 A Boyle and C Chinkin, The Making of International Law (Oxford University Press, Oxford, 2007) 12. 15 It is in this relationship between obligation and enforcement that I describe the nascent accountability discourse as essentially Kelsenian. According to Kelsen's general theory, of course, 'the function determined by the legal order is the content of a legal obligation only if the legal order provides a sanction for the non-performance of the function': H Kelsen, The Law of the United Nations: A Critical Analysis of Its Fundamental Problems (Fredrick A Praeger, Westport, CT, 1950) 154. 16 N Bamforth and P Leyland (eds), Accountability in the Contemporary Constitution (Oxford University Press, Oxford, 2013) 1: 'Ideas of accountability play a prominent role in contemporary discussions of constitutional law and practice, and politicians, judges and other actors tend frequently to claim, whatever the substantive viewpoint or proposal which they advocate, that more or better accountability is their end-goal'. Harlow even suggests that accountability has 'joined the classical trilogy of sovereignty, rule of law and separation of powers as a directive principle of constitutional law': C Harlow, Accountability in the European Union (Oxford University Press, Oxford, 2002) 7. Security Council accountability and the turn to (global) constitutionalist thinking in international law runs deeper than this. By pinpointing the chronological and normative links between these two sites of discourse, I want to suggest that it is impossible to understand one without reference to the other, to the point where the meaning of accountability in the Security Council context will necessarily be predicated on the perspective taken on global constitutionalism.
To show this, section II of this article surveys the turn to Security Council accountability and notes several blind-spots in the current debate. Section III situates the turn to accountability within the broader turn to the language of global constitutionalism in international law. Section IV introduces the distinction between 'liberal-legal' and 'political' styles of constitutionalism. This heuristic device is well established in Anglo-American constitutional thought 17 and has been applied in the context of the European Union, 18 but it is much less familiar to international lawyers. The central argument is that mainstream Kelsenian approaches are indicative of a prevailing liberallegalist style of global constitutionalism in international law; as such, many of the blind-spots in contemporary discussions on Security Council accountability are born directly in the constraints of liberal-legalism. In Section V, I suggest that a broader conception of accountability through the lens of a more overtly political (global) constitutionalism can elucidate new ways to perceive and, importantly, to critique the Security Council.

II. The turn to Security Council accountability
It is something of a truism to suggest that the Security Council wields great power under Chapter VII of the UN Charter. In the fulfilment of its 'primary responsibility for the maintenance of international peace and security', 19 the Council can impose a range of enforcement measures, from non-forcible measures (namely economic sanctions) to coercive measures, including the authorization of military force. 20 Crucially, these measures are binding on all member states. 21 The cumulative effect of these provisions is that the Council is surely the most powerful institution in global politics. According to the International Law Association, 'power entails accountability, that is the duty to account for its exercise'. 22 The recent shift towards thinking about the Security Council in terms of its accountability is best understood in light of three chronological 'waves'.
During the first wave, there was almost no discussion of limiting the power of the Security Council, let alone broader questions of accountability. There are two main explanations for this. The doctrinal explanation is that international law had not yet come to terms with the legal relationship between international organizations and their member states. As a corollary of the legal personality of the United Nations, it is accepted that the organization and its organs enjoy both rights and responsibilities in international law. 23 However, even at this early stage the absence of court or tribunal with compulsory jurisdiction to enforce these responsibilitieswhatever they werewas perceived as the most pressing challenge. 24 For Kelsen, in the absence of judicial enforcement, the only possible conclusion was that 'the Security Council is not bound strictly to comply with existing law'. 25 The more practical explanation is that because of the ideological differences that existed between permanent, veto-wielding members, during the Cold War the Council was stuck in a near-perpetual state of political paralysis. Its immense power remained largely hypothetical. Caught between a rock and a hard place, the latter was the Council's permanent residency due to its composition and voting privileges. 26 The second wave began in the 1990s, as a revitalized Security Council displayed an increased willingness to exercise its powersthat is, to 20  'the enervating effect of the lack, or near lack, of courts with compulsory jurisdiction is nowhere more damaging than in this aspect of international law'. 25 Kelsen (n 15) 275. Seyersted proffered that any limits on the powers of the United Nations and its organs were 'internal, constitutional matters', which did not 'affect the external capacity of the organization under international law': F Seyersted, 'United Nations Forces À Some Legal Problems ' (1961) 31 We are currently living in a third wave, which is defined by an important semantic shift: the scrutiny now has a frame of reference, the objective is to constrainor even controlthe Security Council, to find the means through which to ensure its legal accountability. Much of this discussion has taken place in the context of Article 41 sanctions, especially the 1267 sanctions regime, which subjects individuals and entities with suspected links to Al-Qaida and associated groups now including ISIL (Da'esh) to widespread 27  measures including asset freezing and travel restrictions. 32 The situation of an individual listed under the 1267 regime has been compared with that of Josef K in Kafka's The Trial, 'who awakens one morning and for reasons never revealed to him or the reader is arrested and prosecuted for an unspecified crime'. 33 The sanctions example demonstrates well the two interconnected factors that are driving the third wave of accountability discourse. The first is the individualization of the consequences of Security Council decisions. 34 The second is the felt need to judicially enforce obligations incumbent upon the Councilespecially human rights obligationsto protect individual rights. 35 With these two factors in mind, it is telling that accountability is often packaged with the doctrine of international responsibility. At its root, international responsibility consists of three interrelated premises. First, actors who enjoy international legal personality have a duty to uphold their legal obligations. Second, a failure to uphold these obligations triggers the 'responsibility' of that actor. Finally, as a corollary to that responsibility, the actor agrees to accept the legal consequences that flow therefrom. 36 Crucially, these premises not only constitute the doctrine of international responsibility but provide the foundational organizing principle of the international legal order itself. In this sense, the association of accountability and responsibility is logicalintuitive even. As Krisch perceptively notes, 'It is natural human behaviour to fill voids with what we know. When we are thrown into unfamiliar spaces, we try to chart them with the maps we possess, construct them with the tools we already have.' 37 The doctrine of international responsibility is indeed a map familiar to the international legal lexicon. There is perhaps no more familiar map.
Underpinning this intuition, however, is a more normative connotation. Where there is doubt as to whether accountability is an intrinsically legal 472 ben l. murphy concept, 38 there is no such doubt when it comes to the doctrine of international responsibility. It is, conversely, perceived as the 'toughest' branch of international law: 'it puts a harder edge on legal rights and duties'. 39 Herein lies the appeal of international responsibility: it provides the leitmotif to achieve the ambition of holding the Security Council accountable in international law.
The above notwithstanding, the 'accountability as responsibility' thesis suffers from an inherent paradox. The very sentiment that drives the debate the felt need to establish binding justiciable obligationsuses as its frame of reference a doctrine that relies, as its foundational basis, on the existence of these obligations. Where there is no obligation, therefore, there can be no responsibility. The paradox also has a further implication. Even where obligations do exist, they are typically only triggered by a positive affirmative decision of the Council. As we have seen, the accountability discourse has arisen predominantly in response to such decisionsfor example, the establishment of criminal courts, the inclusion of individuals on sanctions lists, the authorization of the use of military force. It is the legality of a decision already made that determines whether the Council can be accountable for the consequences that flow from it.
Due to this limitation, the third wave of accountability discourse is unable to capture the breadth and depth of the Security Council's various accountability deficits. At this juncture, it is sufficient to note just three 'blind-spots'. The first is exemplified by the Council's response to the Paris terrorist attack of 2015. Resolution 2249 quickly determined that the perpetrators 'constitute an unprecedented threat to international peace and security'. 40 However, while seemingly in agreement that a response of some sort was necessary, the permanent members of the Council were manifestly unable to reach a consensus on the substance of what that response should be. As a result, the resolution is inherently ambiguous. The operative paragraph 'Calls upon Member States … to take all necessary measures … on the territory under the control of ISIL … in Syria and Iraq'. 41 The problem with this ambiguity is that at the time the resolution was passed, a US-led coalition was already conducting airstrikes against ISIL bases in Syria, without the consent of the Syrian government. While not explicitly providing the legal basis for such strikesfor such resolutions normally explicitly 'decide' that states may, or 'authorize' states to use forcein 'calling upon' 38  members to take such measures, the resolution might easily be read as an implicit validation. 42 In light of criticism from Syria and Russia of this apparent incursion of Syrian sovereignty, we might conceivably ask who is to be accountable. In the case of the Security Council, the question would have to be rephrased: How can we account for ambiguity? Indeed, beyond this example, ambiguity in Council resolutions is a perennial issue. 43 However, from the perspective of international law, there is no 'duty to be clear', nor does the Charter impose any such obligation on the Security Council. 44 This might explain why so little has been said about this aspect of the Security Council's practice in the accountability debate.
A second blind-spot relates to the controversial issue of Security Council inaction. While the expansive nature of the Council's practice is the focal point of the accountability discourse, the converse is not true: the concept has not been applied as systematically to situations in which the Council fails to act. It would be too much of a stretch to say that the Council's expansive practice has become the new status quo. Instead, the practice might more appropriately be categorized by its consistent inconsistency. For every example of enforcement action against perceived threats to international peace, a comparable situation meets inaction: for every Libya, there is a Syria, a Rwanda or a Srebrenica; for every rock a hard place. 45 However, the scope of the Council's discretion under Chapter VII is almost completely unfettered. So, again, this aspect of the Council's practice is stymied by the 'accountability as responsibility' paradox. The positivist bent of accountability discourse means that its advocates struggle when it comes to nonlegal or at best 'quasi-legal' questions such as the material conditions that should trigger enforcement measures.
In a final blind-spot, legal commentators appear fixated on the notion of 'holding' the Security Council 'to account', a fixation that is aided and abetted by the conflation of accountability and legal responsibility. It is important to note, however, that the concept of accountability has three 42 D Akande and M Milanovic, The Constructive Ambiguity of the Security Council's ISIS Resolution' (21 November 2015) EJIL: Talk, available at <https://www.ejiltalk.org/the-construc tive-ambiguity-of-the-security-councils-isis-resolution>. 43  constitutive dimensions, not one. The first dimension is the expectation that an actor will explain and justify a decision ('give an account'), which is closely linked to the principle of transparency, accountability's 'alter-ego'. 46 In the absence of an explicit duty to give reasons in international law, this dimension is almost completely overlooked. The second dimension is the 'standard-setting' phase. Legal commentators naturally invoke the principle of legality as the relevant criteria for assessment, ignoring broader questions of the legitimization of Security Council decision-making. The final dimension is the 'consequences' phase. The third wave of accountability discourse is defined by a normative preference for judicial over political processes to impose these consequences. The adoption of such rigid positions masks significant internal contestation over the meaning and relative relevance of each dimension of accountability. The third wave has thus failed to engage with the concept of accountability in a holistic sense. 47 Indeed, this conceptual lacuna is a key factor contributing to the more practical blind-spots relating to Security Council ambiguity and inaction.

III. Accountability as a product of the turn to 'constitutionalism' in international legal thought
The turn to Security Council accountability has not taken place in a vacuum. In this section, I suggest that the failure to grapple with accountability's internal conceptual contestation is rooted in the fact that international lawyers' eyes are fixed to certain existential tensions. 48 These are categorized in the following paragraphs as a 'contractualism tension' (relating to the nature of international institutional authority), a 'functionalist tension' (relating to the prevailing legal theory to understand and rationalize this authority) and a 'fragmentation tension' (relating to the capacity of international law to respond to excesses of this authority). These tensions are linked thematically by the anxieties that they breed in the mind of the international lawyer. 49 46 Harlow (n 16) 7. 47 In Section V, we return to this 'three-dimensional' approach to the concept of accountability, noting the range of accountability mechanisms available once a broader framework of analysis is adopted. 48  Although the idea of global constitutionalism is neither rooted in, nor did it emerge specifically from, public international law, its particular allure is apparent when set against these anxieties. Indeed, in an emerging methodological trend, constitutional imagery and analogies are invoked directly in juxtaposition to these tensions or similar formulations. 50 It is in this sense that it is possible to speak of a discrete 'global constitutionalist project' in international law. 51 In this project, the concept of accountability plays an important role. It stands to operationalize a vision of a constitutionalized international legal order. However, as will be shown, as it has developed predominately to alleviate the anxieties of international lawyers, it is a particularly narrow vision.

The contractualism tension: Private (delegated) versus public (constitutional) authority
A first tension speaks to the relationship between the Security Council and individual member states. The territorially defined, independent sovereign state is traditionally understood as the prototypical actor on the international stage. 52 According to this orthodox characterization of the international legal order, limitations on a state's freedom of action are only permitted when they are expressly consented to. The converse is also true: states cannot be bound by obligations without their consent. 53 This orthodoxy suggests that when states are bound to comply with a legal rule, as they are bound to comply with Security Council decisions, the relationship is analogous to a private law contract. The obligation is bilateral and transactional: member states delegate authority to the Security Council and Council decisions gain their binding force from the consent and perceived 50 The trend resonates with D'Aspremont's observation that 'speaking in antinomic terms of the law of international organizations … constitutes the mainstream style with which this subject is discussed and debated': D'Aspremont (n 48) 140. 51  476 ben l. murphy mutual reciprocity of states. The private law analogy traditionally allowed for the voluntary creation of binding obligations, 'while at the same time preserving the sovereign's independence and authority'. 54 The 'contractualism tension' emerges when the Council exercises its competence to bind all members in situations where explicit (and often even implicit) consent is lacking. A good example of this predicament is found in the Council's 'law-making' resolutions on terrorist financing. In Resolution 1373, the Council established obligations on states that included the criminalization of certain types of conduct and the freezing of assets of individuals and business entities linked to the funding of terrorism. 55 To some commentators, the Council's power is executive in nature and is limited to responses to specific 'threats to the peace'. 56 This is logical, for the imposition of essentially legislative obligationsthat is, binding, temporally unlimited and relating to an abstract as opposed to a specific threatjars with the structural premises of international law, which place the sovereignty of states at its centre. 57 More than this, though, the nation state's monopoly over the exercise of sovereign power over individuals has always been more than an empirically identifiable reality. To many, it transcended this reality by providing the very roots of, and the context underpinning, the idea of 'public authority', and sovereignty itself, as conceptual phenomena. 58 In an attempt to transcend the 'contractualism tension', recent developments point to a shift in conceptual understandings of 'public authority'. This novel scheme attempts to redefine authoritative acts of international institutions as instances 54 F Kratochwil, 'The Limits of Contract' (1994) 5 European Journal of International Law 465 at 465. This reasoning enjoyed pre-Charter judicial support. In the 1923 Wimbledon case, the Permanent Court of International Justice found that, rather than being incompatible with sovereignty, the ability to voluntarily enter into commitments through international organizations actually represents an attribute of state sovereignty:  57 The formalistic response to this 'sovereigntist concern', which holds that ratification of the Charter amounts to implicit consent to be bound by future decisions, is unsatisfactory. Members did not foresee and could not reasonably foresee the various ways in which the Council would (re) interpret its mandate: see Peters (n 35) 784. 58 Loughlin articulates this position in particularly stark terms, stating that sovereignty is a concept that is 'entirely inseparable from the state': Loughlin (n 17) 73.
'international public authority'. 59 Accepting this possibility has a rippling effect on how we might conceive of the nature of international law. From a system based on the principle of jus inter gentesthe law established by states to regulate essentially private relations between states as juridical entitiesthe 'constitutional' reconfiguration speaks to the principle of jus publicum. 60 Its explicit aim is to establish a legal framework for any exercise of public authority, irrespective of its source, and to subject that authority to the requirements of public, or constitutional law. 61 To what end? Functionalism versus global constitutionalism Giving rise to a second tension, the urge to subject the Security Council to public law standards runs contrary to a 'functionalist' impulse that has implicitly undergirded legal discourse on international institutions. 62 The theory of functionalism relates to the teleological idea that states create international institutions to realize certain commonly held values. 63 This normative premise traditionally instilled in international lawyers a sentiment that any independence and influence an international institution gained at the expense of its member states contributed to the effective functioning of the institution and the functioning of international law. 64 Examples of this quasi-romantic inclination towards institutional power are omnipresent in twentieth-century international legal thought. Kennedy, for example, located the move to institutions in turn-of-the-century reformist aspirations that would 'convert passion into reason'. 65 To Claude Jr, this 59 A Von Bogdandy, 'General Principles of International Public Authority: Sketching a Research Field' (2008) 9(11) German Law Journal 1909. 60 Ibid 1914. 61 Ibid. 62 Functionalism's dominance is 'implicit' because international legal scholarship relating to the role of international institutions traditionally has suffered from a dearth of explicit theorizing. Klabbers describes the discipline as 'immature' because it lacks 'a convincing theoretical framework': J Klabbers, Introduction to International Institutional Law (2 nd edn, Cambridge University Press, Cambridge, 2009) 3; HG Schermers and NM Blokker, International Institutional Law: Unity within Diversity (5 th edn, Martinus Nijhoff, The Hague, 2011) 9: 'It is true that theoretical reflection in the field of international organizations has been limited'. 63   represented 'a secular trend toward the systematic development of an enterprising quest for political means of making the world safe for human habitation'. 66 In its most evocative form, the theory finds its home in the idea that international institutions can provide the 'salvation of mankind'. 67 While mainstream approaches perhaps use more modest, temperate language, the majority of the discipline's most influential writers have echoed this sentiment: From Westlake in the 19th century, to Lauterpacht and Kelsen in the mid-20 th century, to Franck and Cassese at the end of the Cold War period … all, in various ways, placed their hopes in increasingly autonomous international institutions to secure the rule of law in international affairs. 68 The functionalist mindset held that international institutions were the 'guardians of international law rather than as potential violators'. 69 It followed, therefore, that the converse must surely have been true: it 'could hardly be seen to engage in activities that would warrant control'. 70 Even if they did engage in such activities, Mitrany, the archetypal functionalist, denied the 'habitual approach … that international action must have some overall political authority above it'. 71 The habitual approach rejected by Mitrany is, in many ways, the very root of the concept of constitutionalism. 72 To Klabbers, for example, global constitutionalism 'has to do with placing limits on the activities of international organizations, subjecting those organizations to standards of proper behaviour'. 73 As we have seen, the recent practice of the Security Council shows that any assumption that international institutions comply with the rule of law, let alone secure this value, is increasingly insecure. The appeal of constitutionalist language, therefore, lies in its promise to constrain the excesses of the Council's powers. 66

The systemic tension: Fragmentation versus global constitutionalism
If constitutionalism is to do with limits, however, it runs into a final tension. The Security Council is only one of an exponentially increasing body of functionally distinct international institutions. The lack of uniformity or 'fragmentation' between different institutions speaks to a 'systemic' concern, whereby the international legal order is diluted into a set of 'normative islands constituted by partial, autonomous and perhaps even "self-contained" legal sub-systems'. 74 The anxiety is that these sub-systems fail to come together in a unified whole. This is compounded by a 'deformalization' anxiety: in the decentralized, inherently indeterminate international legal space, it is not readily apparent how international institutions can be restrained, regulated and controlled. 75 The dual anxieties felt by the fragmentation and deformalization tensions speak to different elements of global constitutionalism's allure. 76 First, the language of constitutionalism alleviates the fragmentation worry by imagining a more integrated, coherent international legal order. 77 Put in another way, it offers highways between otherwise fragmented, isolated villages. 78 In a second move, deformalization is assuaged by instilling a sense of hierarchy, or verticalization, into systematic understandings of international law. 79 This move is achieved predominantly by elevating particular rules of a supposedly 'constitutional' character over and above so-called 'ordinary' rules. 80 In this context, the example of jus cogens norms is particularly illustrative. 81  78 Klabbers (n 76) 11. 79 Ibid 1: 'Fragmentation, verticalization, and constitutionalization form the holy trinity of international legal debate in the early 21st century.' 80  international law do not exist to satisfy the preferences of individual states, but for the benefit of the international community as a whole. This speaks to the unifying appeal of global constitutionalism. In turn, jus cogens rules are taken to enjoy a status superior to all other international legal rules, thus representing global constitutionalism's sense of hierarchy. It is telling that the proposition that the Council is bound by jus cogens carries almost unanimous consensus. 82 The objective, 'constitutional' quality of jus cogens norms surely contributes to this widespread agreement. The interpretation of treaty and customary rules is, comparatively, much more reliant on subsequent (subjective) state attitudes, and there is no such agreement on their status vis-à-vis Security Council decision-making. 83

Interim conclusion: Accountability and the global constitutionalist project
The 'turn to accountability' has taken place in the shadows of the broader global constitutionalist project in international law. As a subsidiary discourse within this broader project, accountability stands to operationalize a vision of a constitutionalized order; however, I suggest that this vision is limited. It is limited by the methodological constraints of the project itself, which views 'constitutionalization' not so much as an iterative, organic process, 84 but in a far more combative sense. This is evidenced by the fact that, more often than not, 'constitutionalism' is invoked in stark juxtaposition to some 'other' theory, be that 'contractualism', 'functionalism', 'fragmentation' or alternative formulations of similar tensions. In different ways, each of these tensions reflects the incongruity between traditional (state-centric) understandings of international law and the increasingly autonomous nature of international institutional authority. The appeal is in the juxtaposition: constitutionalism provides the tools to 82 For example, de Wet (n 12) 187-91; Akande (n 31) 332-33; Tzanakopoulos (n 9) 70-72; Henderson (n 13) 499; Hovell (n 12) 99-101. To the extent that courts have broached the matter, the proposition also maintains judicial supportfor example, Kadi v Council and Commission retrieve 'some form of cognitive control over global political life'. 85 International lawyers have reached for these tools with both hands. In a move of disciplinary self-sustainment, international law (especially norms of jus cogens) and international judicial institutions become the bastions of this newly constitutionalized landscape and, by extension, the means through which to realize the accountability ambition.
However, the limitation is also in the juxtaposition. In section II, it was shown that the treatment of Security Council accountability tends to be rather reductive. It revolves disproportionately around the doctrine of international responsibility, leaving several lacunae unresolved. We see now that this reductive treatment is a direct consequence of its implication in the shift to constitutionalist thinking in international law, a shift that is itself reductive in the sense that its raison d'être is to 'resolve the perennial existential insecurity of international lawyers once and for all'. 86

IV. From existential to internal dynamics: Liberal-legal and political 'styles' of (global) constitutionalism
It is by no means inevitable that an international legal project of global constitutionalism should display the tensions outlined above. In this section, I argue that these features in fact represent a particular 'liberal-legalist' style of constitutionalism. 87 This will lay the groundwork for the suggestion in the final section that a (global) 'political constitutionalist' lens might offer important insights on how we should conceive of the accountability of the Security Council. 88 The 'liberal-legal' style In section II, I suggested that the individualization of the consequences of Security Council decisions, coupled with a felt need to constrain the Council's power in the name of protecting individual rights, represents the driving force behind the turn to accountability. These forces resonate strongly with two insights of classical liberalism. The first represents the principle of liberal individualism-that is, the liberal notion of the propriety of individual rights. It rests on the 'belief that constitutions serve principally to constrain … power for the benefit of the individual'. 89 The second represents the liberal inclination that political power arbitrarily exercised is destructive not only of individual liberty but also of the rule of law. Interestingly, by bringing these two aspects together, the global constitutionalist project has been described as a 'paradigmatic of a broader phenomenon of cosmopolitan constitutionalism, based on individual rights guaranteed through a transnational rule of law'. 90 'Liberal-legalism' is essentially the exercise of mapping the two insights on classical liberalism, individualism and the rule of law with the theory of legalism. It is therefore important to clarify the work 'legalism' is doing in this rubric. The material and ethical dimensions of legalism are best analysed by reference to the work of Judith Shklar. From a material perspective, legalism seeks to elevate judicial processes over and above political processes. To Shklar, the theory implies that 'the court of law and the trial according to law are the social paradigms, the perfection, the very epitome of legalistic morality'. 91 The idea of 'legalist morality' hints at the ethical dimension of liberal-legalism: it 'holds moral conduct to be a matter of rule-following and moral relationships to consist of duties and rights determined by rules'. 92 From this ethical perspective, the compliance with rules, not the legitimacy of the rules themselves, gives political decisions their value. 93 Liberal-legalism thus perceives legal rules as a set of rational moral principles. 94 Legal rationality is portrayed as not merely different from political rationality, but as self-evidently superior to it. 95 At the international level, this resonates with what Koskenniemi describes as 'a familiar hubris … the assumption that a right ("lawful", "valid", "optimal", "effective") solution already exists somewhere, and the lawyer's task is just to find it and apply it'. 96 Drawing these sentiments together, the general theory of liberal-legal constitutionalism represents four themes. First, in its grammar, practices and institutions, law is autonomous to and superior over politics. Second, the exercise of all public authority should be kept in check by law. Third, the most legitimate way of controlling the exercise of public authority is through the judicial articulation and enforcement of broad principles of legality. Finally, the goal of this project is to safeguard a particular vision of individual human rights. 97 Considering that these themes arise predominantly in the context of domestic constitutionalism, it is telling that global constitutionalism has been described as a scheme that encompasses the following elements: [T]he exercise of authority in accordance with some version of the rule of law, be it limits internal to the organization (emanating from its own documents) or external to the organization (subjecting it to general international law and human rights standards). And in this scheme, an important role is reserved for judicial review: in the final analysis, judges will be deemed to be the guardians of the rule of law and of the constitution, for they are, many would agree, above politics. Constitutionalism typically aims to tame man's quest for power, and aims to do so by providing legal limits. It stands to reason, then, that individuals trained in the law are deemed most suitable to this task. 98 Each theme of global constitutionalism maps strikingly to the four themes of liberal-legal constitutionalism outlined above. Where liberal-legal constitutionalism assumes that law is superior to politics, so too global constitutionalism 'tames man's quest for power … by providing legal limits'. 99 Where the former claims that all public authority should be kept in check by law, the latter endorses 'the exercise of authority in accordance with some version of the rule of law'. 100 Liberal-legal constitutionalism implies a preference for judicial over democratic processes, and even when the theory is translated onto the global plane, apparently 'judges will be deemed to be the guardians of the rule of law'. 101  The 'political' style The distinctively liberal-legalist origins of the global constitutionalist project go a long way towards explaining the legalized and judicialized nature of the accountability debate. An alternative approach, which evokes a more 'political' style of constitutionalism, owes much to the work of John Griffith. 103 Its value is found in its antagonism to liberal-legal constitutionalism. To Griffith, the 'concept of law' is not an inherently 'moral concept'. 104 Instead, the invocation of legal argumentation is itself a 'political act', a statement of a 'power relationship'. 105 In this general framework, 'law is not and cannot be a substitute for politics'; in fact, 'law is politics carried on by other means'. 106 Griffith's observations chime with Shklar's critique of legalism, which despite its claim to be exclusively interested in following objective and impartial rules, she suggests is in fact an ideology. Far from representing an apolitical endeavour, it is itself an expression of political preferences. 107 The logical conclusion of its ideological character, therefore, must be that legalism is just one way among many of conducting political decisionmaking. 108 To Shklar: To show that justice has its practical and ideological limits is not to slight it … The entire aim is rather to account for the difficulties which the morality of justice faces in a morally pluralistic world and to help it recognize its real place in itnot above the political world but in its very midst. 109 Shklar did not use the language of political constitutionalism-in fact, the lexicon had not, at this stage, crossed the Atlantic. However, the accommodation of different political preferences is a key element of political constitutionalism. The premise that the (international) legal system can rest on impartial rules that guide and circumscribe everyday political disagreement is, of course, unsustainable. States reasonably disagree on the most fundamental questionswhether a situation constitutes a threat to international peace and security, whether enforcement action would be necessary and proportionate to that threat; there simply are no objective answers.
Indeed, the strongest criticism of the myth of homogeneity is that it conceals the inherently contested nature of fundamental issues. Its effect is that 'it postpones, rather than encourages, concrete debates on concrete problems'. 110 It might even go further than postponing these debates, by shutting them down altogether in favour of the status quo. This produces a form of settlement bias: 'recasting our situation in constitutional terms can give us the feeling things are settled. The struggle is over, and this is how it turned out.' 111 In other words, it tells us that the political struggle is over: the law has literally ruled. On the contrary, rather than striving for objective (legal) answers to the questions that agitate a society of states with competing subjective interests, political constitutionalism offers a structure for reaching collective decisions. 112 The second theme of liberal-legalism is its innate scepticism towards the exercise of public authority. It champions the limiting power of law. Political constitutionalism, by contrast, proceeds from an innate scepticism towards unrepresentative judicial institutions and aims to show the limited power of law. Instead of taking power away from political institutions and placing it into the hands of the judiciary, political constitutionalism is concerned with understanding the nature of the public authority and the reasons why an institution was originally vested with such authority. The objective is to open the political space to exercise authority in light of this purpose. This approach is, of course, at odds with the methodological tendency to dichotomize global constitutionalist and functionalist perspectives. Instead, it points to a common theoretical heritage between the two. 113 Just as with the functionalists of international law, to political constitutionalists, 'the very heart of the constitution', its definitive feature, is that it exists to enable government action. 114 However, political constitutionalism should not be misconstrued as a theory that offers institutions a blank cheque, subject to no limitations. Instead, identifying the original function that an institution is established to fulfil provides the very criterion against which to measure its performance. 115 This has important implications for a framework of accountability. The criterion for assessment shifts from compliance with the law, to whether the institution has performed its functions effectively in the eyes of the constituency that originally delegated this power.
The reference to the wider constituency speaks to the final line of demarcation between the two 'styles' of global constitutionalism. Liberal-legalism focuses on the relationship between the decision-maker and their affinity to the law. By contrast, political constitutionalism prioritizes the relationship between constituent and constituted power. 116 Where liberal-legalism suggests that the overriding goal should be to protect individual rights, political constitutionalism adopts a less atomistic perspective, stressing the collective good over individual interests. The 'constituting' aspect of constitutionalism, which speaks to the establishment of institutions for states 'to cooperate and coordinate to pursue projects that they cannot achieve on their own', 117 is often underplayed in liberal-legal accounts.
Whereas liberal-legalism suggests a rather passive role for 'constituents', who have rights and can expect that these rights will be judicially protected, political constitutionalism offers a more active role. Bellamy argues that 'it is only when the public themselves reason within a democratic process that they can be regarded as equals and their multifarious rights and interests accorded equal concern and respect'. 118 In international legal theory, it is not uncommon to analogize the role of the state in international law with the role of the individual in the domestic context, in search of the legal order's pouvoir constituant. 119 Schmitt brought this analogy to the fore, noting that implicit in the work of Hobbes, Leibniz, Kant and others is the claim that in international law states live as 'moral persons' in a state of nature, confronting one another as sovereign persons with equal legitimacy and equal rights. 120 The analogy enjoys enduring appeal, as 'states remain the most significant hosts to constitutional discourses, institutions, and structures'. 121 It is therefore impossible to imagine an accountability framework for the Security Council that does not place the Council's pouvoir constituant, individual member states, at its centre. Member states delegated authority to the Security Council, but this relationship did not cease at this foundational moment; it is ongoing. Under this framework, the Security Council is accountable to member states, and therefore must justify its conduct in light of their demands. It is member states, not (only) international judicial institutions, that enforce the Council's accountability.
Having established that current understandings of Security Council accountability are rooted in the global constitutionalist project, I suggest that this project inherently articulates the contradictions of liberal-legalism. However, if liberal legalism is just one tradition, with a particular understanding of accountability, then we can already see how the lens of political constitutionalism might provide an alternative perspective. The commonality of its various insights is a widening of the institutional actors involved in the accountability process.

V. The styles of global constitutionalism and the dimensions of Security Council accountability
In this final section, I return to the three constitutive elements of accountability ('transparency', 'standard-setting' and 'consequences'), noting the various possibilities for the concept of accountability in the Security Council context, depending on the respective 'style' of global constitutionalism adopted.

Transparency
The first constitutive dimension of accountability is the expectation that an actor will 'give an account' of a decision by explaining and justifying it with reference to reasons. 122 In theory, the principle of transparency should be compatible with liberal-legalism. Reason-giving has been characterized as 'one of the essential properties of the concept of the rule of law, if not the essential one'. 123 The constitutional treaties of international institutions often instil a legal requirement to 'give an account' of decisions. 124 However, the Security Council is under no such Charter-derived duty to explain or justify affirmative decisions or decisions not to act. Members of the Council may record a statement of explanation before or after a vote; however, they are under no formal obligation to do so and often do not. 125 Political constitutionalism offers an alternative lens because it goes beyond transparency. It stresses the representative nature of political institutions. From this perspective, the ongoing discourse on reforming the composition of the Security Council in line with shifts in the geopolitical landscape is not separate from, but rather very much a part of, a holistic understanding of accountability. 126 This shift in perspective also brings the debates on reforming the permanent member veto into an accountability analysis. The emergence of an apparent 'global responsibility not to veto' among the permanent members of the Council in cases of genocide, crimes against humanity and serious violations of international humanitarian law may, in time, potentially yield important (positive) consequences for the effective functioning of the collective security regime. 127 In sum, while there are widespread calls for the Council to be more transparent in explaining its decisions and permanent members are encouraged to exercise prudence in the use of their veto, these developments have little traction from a liberal-legalist perspective because any reform would be voluntary as opposed to legally mandated. 128 If these disagreements are to be resolved, it will be in the Council chamber in New York and not in the 123 D Moeckli and RN Fasel, 'A Duty to Give Reasons in the Security Council: Making Voting Transparent' (2017) 14 International Organizations Law Review 13 at 67. 124 See, for example, Consolidated Version of the Treaty on the Functioning of the European Union (2007), art 296. It was held in the Nexans case that Article 296 instils an obligation to 'disclose in a clear and unequivocal fashion the reasoning followed by the institution that adopted that measure in such a way as to enable the persons concerned to ascertain the reasons for it': Nexans SA and Nexans France SAS v Commission (Judgment, Fifth Chamber) [2014] Case C-37/13 P at para 31. 125 Moeckli and Fasel (n 123) 17. 126 See, recently, V Lättilä and A Ylönen, 'United Nations Security Council Reform Revisited: A Proposal' (2019) 30(1) Diplomacy and Statecraft 164. 127 Although, in light of the many unsuccessful attempts to pass resolutions of the General Assembly to concretize this responsibility, even its proponents would admit that this 'responsibility' represents a political commitment rather than a formal legal obligation. See, for example, JBJ Vilmer, 'The Responsibility Not to Veto: A Genealogy' (2018) 24(3) Global Governance 331 at 334. 128 Amendments to the Charter are subject to the permanent member veto: see, UN Charter (1945), art 108. courtroom in The Hague. A political perspective on global constitutionalism will allow us to see these issues as a fundamental part of the accountability discourse.

Standard-setting
On its own, transparency does not necessarily involve scrutiny. 129 The notion of standard-setting marks accountability as a particularly reflexive sociological concept. An actor can only be accountable to some 'other', not in the abstract or isolation. 130 Without this scrutiny, accountability is insufficiently dynamic, because when an 'account' of a decision has been rendered there may still be serious disagreement regarding how it should be assessed. For example, what values should be considered? Whose interests should the accountability forum represent? Indeed, 'accountability cannot be effectively imposed if the criteria against which conduct is to be measured in the process of calling to account are not made clear'. 131 Standards also have an important role to bear on the scope of the accountability process. They define which aspects of the relevant body's institutional competence the accountability process covers and, implicitly, which it does not.
The two 'styles' of global constitutionalism point to different yardsticks when identifying the relevant standards against which to assess Security Council decisions. As we have seen, the principle of legality is central to liberal-legalism. The importance of a political constitutionalist lens allows for a shifting of the constitutional register, a 'means of contesting or justifying issues in terms of legitimate authority, not merely … legality or illegality'. 132 Conventionally, legitimacy is conceptualized as entailing two elements. The first is 'de facto' or 'formal' legitimacy, which is 'akin to the juridical concept of formal validity'. 133 For the Security Council, this is secured rather straightforwardly. Under Article 24(1) of the Charter, the Council enjoys 'primary responsibility for the maintenance of international peace and security'. From a political constitutionalist perspective, it is the second elementthe Council's 'de jure' or 'social' legitimacythat is at stake. Under this rubric, like the concept of accountability itself, legitimate authority can never be exercised in isolation: there 'must be some social group that judges the legitimacy of an actor or action based on the common standards acknowledged by this group'. 134 It is inextricably dependent upon the social perception and recognition of member states.
The sociological character of legitimacy unveils the segue from the first to the second constitutive dimension of accountability. To scrutinize the Council's conduct, member states must have recourse to a (political) 'right of justification'. 135 As Wiener shows, this is particularly important for 'less powerful states against the dominance of strong Western states in international institutions'. 136 This is particularly evident in the case of the Security Council, where permanent members enjoy veto privileges over non-permanent members and decisions are often made in private meetings. Once states are armed with the relevant information relating to why a decision was or was not taken or, in the case of ambiguity, the motivations and intentions of permanent members in choosing a particular wording, their plea to have access to the 'arena of contestation' is answered. 137 Wiener's second insight is that sociological legitimacy promotes 'regular contestation', as opposed to 'spontaneous contestation'. 138 If the relevant standards related to legality only, the discourse would be hemmed in by the 'spontaneous', retrospective nature of the doctrine of legal responsibility. 139 The third insight from Wiener's work on legitimacy is that the meaning of a normin this case, accountabilityderives not from a norm's fixedness of meaning but from political participation in its definition. This is a crucial insight that carries explanatory force in the context of Security Council decision-making. States might comply with unlawful resolutions, or even refuse compliance with lawful resolutions. De jure legitimacy explains why states engage with Security Council decisions in distinct ways, which should be distinguished from obligation or coercion 134  (international law) and self-interest (international politics). 140 Indeed, this sentiment has been endorsed strongly by member states: The effectiveness of the global collective security system, as with any other legal order, depends ultimately not only on the legality of decisions but also on the common perception of their legitimacythere being made on solid evidentiary grounds, and for the right reasons, morally as well as legally. 141 The Council relies on member states to implement its decisions. Therefore, as an empirical matter, the Council is primarily driven in its decision-making by the requirement that the wider international community will recognize decisions as legitimate, as opposed to rigorously ensuring that its decisions comply with international law. 142 The imposition of consequences Finally, accountability involves the 'holding to account' phase in which, based on the prior assessment of the actor's conduct, the accountability forum has the power to impose consequences. Some commentators insist that consequences should be formally imposed. 143 To others, 'the disintegration of public image … as a result of the negative publicity generated by the process' can be just as effective. 144 Crucially, whether the consequences are formal or informal will be predicated on the perspective on (global) constitutionalism that is adopted: A political constitution is one in which those who exercise political power … are held to constitutional account through political means, and through political institutions … A legal constitution, on the other hand, is one which imagines that the principal means, and the principal institution, through which the government is held to account is the law and the courtroom. Accountability by 'law and in the court-room' is, of course, the central premise of liberal-legalism. However, the primary judicial organ of the United Nations does not explicitly have the competence to review Council decisions. While a lack of express conferral has not provided a barrier to domestic courts interpreting their mandate to include an implied power of judicial review, 146 there is little evidence to suggest that the International Court of Justice is inclined to assume this role. This is the case for jurisdictional and institutional reasons. From a jurisdictional perspective, states and only states can be parties to contentious proceedings. Decisions will not bind the Council itself even if its members are implicated in a dispute. 147 From an institutional perspective, the Court traditionally is perceived as functionally horizontal to the Council, as a co-equal organ of the United Nations, as opposed to hierarchically superior. In its Namibia Advisory Opinion, the Court confirmed this relationship, noting that prima facie it is not a constitutional court and 'does not possess powers of judicial review or appeal in respect of the decisions taken by the United Nations organs concerned'. 148 Such supremacy would be required for the Court to annul Council decisions with binding effect.
In the context of this judicial vacuum, in a recent trend, regional and domestic courts have taken to circumventing their own inability to review the legality of Security Council resolutions by determining that domestic implementing measures are incompatible with the relevant local jurisdictional regime. 149 The best-known example of this judicial sleight of hand is, of course, the Kadi jurisprudence. In the words of the Court of Justice of the European Union, 'the obligations imposed by an international agreement  150 To some commentators, this move is reminiscent of a strong dualist construction of the relationship between domestic and international law. 151 However, for this reasoning to work, domestic and regional courts voluntarily blind themselves to the international legal framework within which they operate. Accordingly, the situation more resembles that of monism, but in reverse. While monism traditionally relates to privileging international law at the expense of domestic law, here domestic law is privileged at the expense of international legal commitments. The decision not to comply with the Council decision is, in terms of international law (and therefore from a liberal-legalist perspective), technically unlawful. 152 The above critique does not deny the impact of this type of judicial intervention from an accountability perspective. In future resolutions, the Council is not likely to risk a finding of incompatibility, not least because it relies disproportionately on European states for the implementation of its decisions. Crucially, however, this tactic is based on the legitimization of its conduct, as opposed to the legalization of the same. Therefore, it is best understood through a political constitutionalist frame.
Outside the courtroom, political constitutionalism also opens up the potential for member states to exercise an accountability functionfor example, by acting through the General Assembly. Indeed, one of the defining features of liberal-legalism is that it centres its gaze on external (judicial) accountability mechanisms rather than internal (political) alternatives. If, as per the wording of Article 24(1), the Security Council acts 'on behalf' of the general membership of the United Nations, it stands to reason that it should be accountable internally to the General Assembly, as the plenary organ where the membership is represented. While the Assembly possesses no formal disciplinary power over the Council, 153 there may be some potential for the plenary organ to play a role in terms of political accountability. The annual report is a good example of this. In the only reference to the concept of 'accountability' in the Charter, this report should include 'an account of the measures that the Security Council has decided upon or taken to maintain international peace and security'. 154 As mentioned previously, the annual debate in 2018 may mark an important turning point in the willingness of the Assembly to reconceive itself as an accountability forum.
Going further, under the Uniting for Peace resolution, an emergency special session of the General Assembly can be called 'if the Security Council, because of lack of unanimity of the permanent members, fails to exercise its primary responsibility for the maintenance of international peace and security in any case where there appears to be a threat to the peace, breach of the peace, or act of aggression'. 155 As such, the Assembly could play a conditioning role in relation to Security Council inaction, an aspect of the Council's practice that traditionally has eluded an accountability analysis. Considering the Assembly's constitutional competence, any such determination would lead to a discussion and, at most, a recommendation for collective measures. 156 Nevertheless, it would be an extremely important statement from the plenary organ of the United Nations from the perspective of political accountability.
The above notwithstanding, we should perhaps be cautious of overplaying the Assembly's role as a formal institutional accountability mechanism, evenor perhaps especiallyunder a political constitutionalist lens. There are three main reasons. First, through their global alliance systems, the tentacles of the permanent members of the Council penetrate the Assembly deeply, to the point where a blanket condemnation of a Council decision by the Assembly will be rare. 157 Second, the Assembly's role in the realm of international peace and security is, by definition, subsidiary to the Council's. We have criticized the 'accountability as responsibility' thesis for its reliance on judicial institutions, which breeds an explicitly retrospective form of accountability. To be clear, though, it is not only the nature of the institution that is, judicial or politicalthat determines its temporal position in the accountability process; the position of an institution vis-à-vis other institutions is an equally important determining factor. Due to its subsidiary power, once again the Council decision to which the Assembly is responding will have already been made, so the nature of the accountability function will be retrospective.
Finally, and most importantly, the Assembly has no role to play regarding the 1267 sanctions regime, to many the most pressing accountability issue of all.  158 The Council has thus insulated itself from internal scrutiny through the General Assembly. The only accountability mechanisms available will therefore be externalfor example, through the Office of the Ombudsperson, or through individual states or regional organizations refusing compliance. 159 The final point to consider, therefore, is the status of such non-compliance as an accountability mechanism. It is (theoretically) possible to construct an argument in favour of unilateral non-compliance from a liberal-legalist perspective. Tzanakopoulos, for example, has suggested that unlawful Chapter VII decisions trigger the responsibility of the United Nations. As such, he argues, member states are justified in taking countermeasures to hold the Council to 'account' for this breach, conceptualized as a right of civil disobedience. 160 Supporting this position, in complying with the Kadi ruling, members of the European Union (indirectly) refused compliance with Security Council Resolution 1267itself a form of disobedience.
That said, it is very difficult to move from ad hoc isolated responses to perceived illegality such as the Kadi example to a general legal right to refuse compliance with Security Council resolutions. In any event, even if such a right existed, its designation as a right of 'civil disobedience' would be dubious. It is one thing to argue that civil disobedience is sometimes (politically or morally) justified or even obligatory. This is an intuitive proposition. It is quite another thing to suggest that under certain conditions there is a legal right to civil disobedience. Acts of civil disobedience must necessarily be illegal, otherwise one is faced with the oxymoron of 'legal illegality'. 161 In the words of Raz, 'if one has a right to perform it its performance should not be civil disobedience but a lawful political act'. 162 The positivization of civil disobedience, therefore, is 'neither possible nor advisable since it would divest it of its very essence'. 163 If civil disobedience is necessarily unlawful, the issue of its justification belongs in the realm of the extra-legal, 'located within a spectrum of (politically motivated) resistance, as a reaction against illegitimate concentration of power'. 164 The legalist, positivist emphasis of the global constitutionalist project cannot conceptually distinguish between illegality and civil disobedience, so it fails to see how civil disobedience can be an effective tool of (political) accountability.
VI. Conclusion: Oscillating accountability; or, a tale of two (global) constitutionalisms This article has provided the first attempt to situate the turn to Security Council accountability within broader theoretical developments in international institutional law. The rise in the functional autonomy of international institutionsof which the practice of the Security Council provides perhaps the best examplehas triggered certain existential tensions in the discipline as a whole. The felt need to overcome these tensions drives what might be described as a 'global constitutionalist project' in international law. In the face of such tensions, constitutional analogies provide something of an intellectual comfort blanket. They purport to offer a workable language where conventional private law approaches to international institutional authority are no longer deemed sufficient. Where the teleological rationale that international institutions exist to promote the common good no longer holds, global constitutionalism promises mechanisms of control. It offers the image of a coherent, unified international legal order to transcend systemic anxieties relating to fragmentation and deformalization.
Wherever constitutionalism is invoked, the premise is that the existential tensions somehow cease to be a factor; they give way to the newly constitutionalized international legal landscape. In international legal circles, this narrative tends to be viewed in positive terms: it connotes the idea of 'progress'. 165 I have attempted to demonstrate the convergences between the progress narrative of the global constitutionalist project and the political theory of liberal-legalism. These convergences are best demonstrated by the fact that, in a veiled move of disciplinary self-sustainment, the apparent rationality and superiority of international law are central to the narrative, and international judicial institutions are elevated to the position of the 'guardians' of this emergent constitutional order.
As a subsidiary discourse within this broader project, 'accountability' has emerged as the conceptual term of art to operationalize this vision of (global) liberal-legal constitutionalism. However, just like its parent concept, the invocation of accountability will invariably carry a normative connotation. 164 Ibid. 165 Collins (n 51) 253.
Crucially, I have argued that accountability's normative baggage is not separate to, but rather specifically predicated on, the themes of liberallegalism. Juxtaposing global constitutionalism to existential tensions in international law, therefore, can only take the debate so far. It will inevitably lead to a reductive understanding of constitutionalism and, by logical extension, of the value of accountability.
That said, the endeavour to reach a holistic understanding of accountability in the Security Council context does not necessitate throwing the baby out with the bathwater. Instead, the task should be to more explicitly acknowledge the connection between these two sites of discourse: the idea that lurking behind every theory of accountability lies a theory of global constitutionalism. 166 As such, a distinction that is internal to constitutionalist debates might offer a more appropriate and encompassing frame. I have argued that the meaning, scope and applicability of the concept of accountability turns on the perspective that one takes vis-à-vis two 'styles' of thinking about global constitutionalism. In this tale of two constitutionalisms, the contemporary accountability debate should be viewed in the 'nature of a magnetic field' within which 'liberal-legal' and 'political' styles of constitutionalism 'serve as different poles exerting influence'. 167 As it stands, the magnetic pull of liberal-legalism is stronger. However, as the Council's legal responsibilities will only be triggered retrospectively, the liberal-legal approach to accountability will inevitably be inchoate. The approach cannot accommodate non-legal aspects of the Council's various accountability deficits, such as ambiguity and inaction. Going further, even when measured against its own terms, the liberal-legal approach is found wanting. The Security Council is under no legal obligation to explain or justify its decision-making processes, the extent to which the UN Charter and general international law provide substantive constraints is clouded in ambiguity and there is no direct mechanism for judicial review. Mainstream approaches thus fail in their original task: in the eyes of international law, the Council does not emerge any more or less 'accountable' in any tangible (positivist) sense.
An alternative approach is necessary to avoid a sense of creeping utopian reformism in which, under the banner of 'accountability', international legal rules and judicial institutions are credited with a 'constitutional' role they were never intended to fulfil. Once the shackles of liberal-legalism are released, a political constitutionalist lens presents new insights into how we might perceive and critique the Security Council, alongside important and distinct ways of understanding and demanding its accountability.
