The liberal international legal order faces a legitimacy crisis today that becomes visible with the recent anti-internationalist turn, the rise of populism and the recent Russian invasion of Ukraine. Either its authority or legitimacy has been tested many times over the last three decades. The article argues that this anti-internationalist trend may be read as a reaction against the neoliberal form taken by international law, not least over the last three decades. In uncovering the intricacies of international law’s legitimacy crisis, the article uncovers the paradox of global constitutionalism: that its need to adopt a sectoral form of integration may cause a legitimacy gap/deficit because international authorities, resting their legitimacy primarily on instrumental grounds, may face problems in compensating for the legitimacy deficit caused by the erosion of domestic sovereignty and extending their legitimacy to non-instrumental grounds. This paradox has one necessary structural and two contingent content-related implications for domestic democracies: (1) it necessarily narrows down the regulatory space of nation-states; and this may in turn (2) impair democratic stability and solidarity, and (3) provide a fertile ground for populism. Drawing on Raz’s service conception, the article focuses on the interaction between international and domestic authorities and highlights the problematic aspects of the neoliberal constitutionalization of international law.

As part of their continuous effort to enhance the effectiveness and democratic legitimacy of human rights treaties, human rights treaty organs have increasingly fostered a direct relationship with various state organs, thereby penetrating the ‘states’ that traditionally have been treated as monolithic legal entities. Treaty organs review the decision-making process of each type of state organ – courts, parliaments and administrative organs – and make remedial orders that are substantially addressed to specific state organs. Such phenomena go hand in hand with the relativization of the distinction between the legal spheres in which human rights treaty organs and state organs operate. This is the first study to address such phenomena as a totality. It constructs the ‘separation of powers in a globalized democratic society’ theory, thereby proposing how each type of state organ and the treaty organs should interact under human rights treaties. Its findings contribute, first, to the harmonious achievement of the effectiveness and democratic legitimacy of human rights treaties; second, to the reform of the classical paradigm of international law, in which monolithic states are the only relevant legal entities; and third, to the long-standing debates on the relationship between international and national laws from a new angle.

Private actors and institutions, and by extension private law itself, are increasingly being forced to reckon with a multiplicity of challenges that extend beyond the domain of private law as it is traditionally conceived. They reflect threats to the global constitutional order and liberal constitutionalism, and threats to individual and collective fundamental rights and constitutional values. As a result, the role of private law in framing and facilitating the development of the global economy and globalization often does not fall within the direct purview of public international lawyers. This editorial aims to examine the role of private law in the litigation and enforcement of public interests against the background of the public/private divide. This is done in light of the increasing role adopted by private actors, including corporations, beyond the private realm.

Digital constitutionalism is a strand of scholarship that focuses on the relationship between constitutional law and the socio-legal challenges posed by the digital revolution. However, such scholarship often builds uncritically on the tenets of liberal, state-centred constitutional theory, giving rise to contradictions between analytical starting points and normative aspirations. Against this background, with an approach inspired by societal constitutionalism, this article engages with digital constitutionalism as both an object and a means of critique. As an object, digital constitutionalism is assessed in the light of its contradictions. As a means, digital constitutionalism is used to assess the limits of traditional, liberal, state-centred constitutional theory. In other words, societal constitutionalism is the theoretical lens used to both deconstruct and reconstruct digital constitutionalism according to its normative aspirations. The article has three main goals: first, linking different discourses within digital constitutionalism, highlighting its critical potential; second, advancing some proposals based on such reflections; and third, bringing digital constitutionalism closer to the broader global constitutionalism discourse. After an overview of societal constitutionalism, the article focuses on digital constitutionalism’s definition and three functionally differentiated systems: politics, economy and law. For each of them, it highlights analytical and normative gains deriving from the societal constitutionalism-based approach as well as policy proposals to be developed further.

This essay proposes the epistemic ethos of passionate humility for knowledge production about global constitutionalism in the aftermath of Russia’s full-scale invasion of Ukraine. By employing the conceptual strategy of elucidation, passionate humility can reveal a counter-intuitively counter-hegemonic use of the global constitutionalist triad of human rights, democracy and the rule of law in the Ukrainian resistance against Russia’s war. As an approach to knowledge production, passionate humility addresses epistemic ignorance by retrieving situated non-imperial knowledges while also confronting the ambivalent politics of such knowledges. It therefore hints at how we can both decentre and make use of resources associated with global constitutionalism, without valorizing western elitist discourses, reinscribing the inter-imperial mode of knowledge production or sanitizing vernacular knowledges. Passionate humility does so in three moves: it problematizes hegemonic epistemic frames (either west-centred or Russia-centred); it foregrounds complex social agency, which resists a fixed theoretical or ideological language; and it reveals the contextual deployment of the Occidentalist language of global constitutionalism in the Ukrainian public discourse as a practice of negotiated subjecthood. Such practice can be counter-hegemonic without being inherently progressive.

This introduction briefly discusses the global constitutional issues raised by ocean governance and introduces the three pieces from our Agora contributors.

The Russian invasion of Ukraine has widely been seen as a failure of the international legal order, which could neither stop Russia from launching a war of aggression, nor prevent the perpetration of international crimes. In such a reading, great power politics have (once again) trumped international law. We argue instead that international law plays a crucial part in the conflict by providing a semantic infrastructure, which the opposing parties use to justify their actions, try to re-draw limits of permissible action and negotiate changing ‘red lines’ with the enemy. Drawing on the notion of lawfare, we show how the pragmatic (mis-)use of international law flexibly delineates boundaries and stabilizes expectations between adversaries even as they are contested in the current war. We focus on claims about self-determination and self-defence to justify the use of force; categorizations of combatants; and weapons transfers and the status of third states. That international law can be violated or reinterpreted to breaking point does not make it irrelevant. To the contrary, it recalls its important role as a language of conflict and compromise, beyond strictly legalist as well as dismissive realist views.

The relationship between balancing and proportionality has not always been clear. Because part of the literature falls short of adequately differentiating between the two tools, many people have become conditioned to see an instance of proportionality whenever the word ‘balancing’ is dropped. As a consequence, the ubiquity of balancing brought about the feeling that proportionality is equally ubiquitous. In this article, I show that the proportionality test is necessarily linked to judicial review and how this link is key to understanding why not every instance of balancing is part of the proportionality test and that proportionality cannot be as ubiquitous as many have claimed. This has not only analytical relevance, but also institutional consequences.

The recent fortieth anniversary of the United Nations Convention on the Law of the Sea (UNCLOS) has sparked a good deal of reflection and retrospection. Looking back, it is clear that the Convention’s architects carefully navigated, and selectively absorbed, a number of competing visions of oceanic governance, from freedom to enclosure to visions of Global North–South equality. This made the Convention’s construction period a very drawn-out and painful one – longer than for any other international treaty in history – and while some hopes were realized, others were dashed. Forty years on, it is important not to let its current canonical status blind us to the fact that the Convention came close to being a failure, and that things could have gone differently at a number of critical junctures. Nor should it stop us asking whether UNCLOS is really fit for purpose today. In this article, I situate the Convention within wider developments in the global economy and the global environment, and consider the role it has played in promoting goals of global justice and environmental protection.

Russia’s continued aggression against Ukraine has sent shock waves around the world. Russia has violated the most fundamental rule of international law and most people intuitively feel that the war in Ukraine has changed the entire landscape of international society. Given what is clearly a turning point, it is difficult to assume that global constitutionalism founded on ‘human rights, the rule of law and democracy’, called ‘the constitutional trinity’, will not undergo any changes. Can global constitutionalism survive such a difficult moment? This is a fundamental question that global constitutionalists must address. This article answers this question in the affirmative. First, despite its gross violations of international law, Russia is not necessarily attempting to withdraw from the current framework of international law. The existing individual-centred elements in international law, which are the central pillar of global constitutionalism, will not be replaced by any alternatives. Second, even if the existing framework of international law remains viable, there is an undeniable risk that the polarization of international law accelerated by the ongoing war will negatively affect global constitutionalism. Such polarization may hollow out the constitutional trinity in international law. However, global constitutionalism will continue to function as the principal cognitive framework for international society because the exercise of individuals’ rights embedded in international law will incessantly provide energy for global constitutionalism. This article concludes that insofar as international law keeps its individual elements, global constitutionalism will be able to retain its normative power under the present predicament in the world.

There is increasing awareness that the ocean touches all aspects of our lives and that a healthy ocean is central to a healthy planet and sustainable future. The ocean is a highly connected system and ocean science is characterized by voluntary international collaboration supported by an enthusiastic and engaged community. Increasingly, it is being recognized that international structures and instruments need to be stronger and more holistic than the current arrangements. This article outlines some perspectives on this, drawing on experience in ocean science and scientists at national, international and intergovernmental levels.

The essential role of parties in democracies makes it important to keep them democratic. This article argues for sortition-based citizens’ assemblies (CAs) organized in and by civil society to formulate democratic standards for political parties to follow, to evaluate them individually and to criticize them publicly if they do not. This is a third and potentially complementary way to keeping parties democratic, placed between militant democracy on the one hand and citizen vigilantism on the other. Militant democracy is challenged by the fact that few democratically problematic parties are ostensibly anti-democratic and therefore likely to fall under the legal criteria for issuing party bans and other legal sanctions. Militant democratic measures are also likely to be ineffective and are vulnerable to abuse. Citizen vigilantism, whereby active democratic citizens take on the responsibility for protecting democracy, deals better with the ambiguous nature of democratically problematic parties but suffers from a lack of democratic authorization and clear standards of critique. While not perfect, the proposed model remedies many of the shortcomings of both approaches. Contributing to an emerging literature on CAs as instruments in the protection of democracy, the article evaluates the model’s normative justifiability, feasibility and likely effectiveness.

This article explores the use of constitutional narratives in social media platform governance, addressing the concept of digital constitutionalism. It aims to elucidate how digital constitutionalism manifests in platforms and the implications for democratizing these governance environments. It argues that digital constitutionalism exposes three goals toward platform governance: (1) an analogous application of constitutional values in private landscapes; (2) an ideological framework permeating multiple normativity levels; and (3) a policy consideration framing the symmetry of regulatory efforts with fundamental values. These three objectives hinge on a liberal and normative approach to constitutionalism, detaching from the political and social considerations at the centre of constitutional democracy. The article argues that this leads to extensive legitimacy issues when considering the transnational character of social media platforms and the localized issues of its users, as explored through an analysis of Meta’s Oversight Board. It is argued that a societal perspective of (digital) constitutionalism must guide the institution’s goals and procedures to promote legitimacy and accountability. This societal approach exposes the reliability issues of the established self-referencing system. It also allows an analysis of the hybridization of traditional constitutional principles in the emerging societal constitution developed by the corporation.

Firmly cemented in history as a connector of people, a facilitator for trade and transport routes and a driver of culture and heritage, the ocean has directly influenced globalization, and humanity more generally, for generations. While the ocean was perhaps once viewed as infinite and insurmountable, globally our oceans, coasts and seas have experienced unprecedented change in recent decades with climate change, loss of biodiversity and overfishing among the challenges being addressed through contemporary ocean governance. Moreover, and crucially as we continue to strive for sustainable ocean futures, the global ocean is increasingly being recognized as a peopled space. This article explores the role of ocean literacy as we look towards achieving sustainable ocean futures.

The Russian war against Ukraine has challenged fundamental norms such as sovereignty, non-interference and the prohibition of the use of force. It has led to diverse reactions from the international community. Only very few states sided with Russia, some states remained neutral, while the vast majority condemned the attack and supported Ukraine in its right to self-defence. Thus, although there is no legal obligation, many states display behaviour that goes beyond diplomatic support. They support Ukraine financially and even deliver weapons to support Ukraine in its right to self-defence. In this article, we conceptualize different types of actors’ behaviour in world politics. We distinguish between responsible, irresponsible, appropriate, and inappropriate behaviour. We apply this typology to states’ reaction to the Russian war against Ukraine. The typology enables us to analyse the variation of the responses with reference to norms and responsibility, two core concepts of International Relations (IR) Theory and global politics. Counterintuitively as it might seem, we argue that the support of Ukraine with weapons can be categorized as responsible behaviour as it displays an over-fulfilment of the right to self-defence norm, which leads to the emergence of a new norm: the responsibility to support norm.

Federations present difficulties for prevailing theories of constituent power, which usually attribute ultimate constitution-making authority to a singular people. This article examines how a ‘pluralized’ constituent power functions in federal systems. It argues that the operation of plural constituent power in federations reflects a distinctive model of constitutional formation according to which a ‘polity of polities’ is established and sustained through the maintenance of a tension between plurality and unity.

The contemporary crisis in relation to constitutional literacy relates not to the lack of knowledge that citizens possess about fundamental constitutional texts, but to the considerable lack of development in relation to what constitutional literacy itself entails. This article accordingly unpacks the notion of constitutional literacy: its importance, its characteristics, and its variable nature. Using a comparative lens, the article invites reflection on the role we expect citizens to play in our democracies, and especially the associated knowledge and skills required for successful state performance. We suggest that constitutional literacy is exceptionally multifaceted and fluid in nature, which serves to make its conceptualization and measurement challenging endeavours, and certainly more so than the easy invocation of this notion may assume at first blush. In this regard, engaging with the constitutional text, while an integral component of constitutional literacy, is ultimately only one part of the puzzle.

Constitutional reform in the European Union suffers from a post-functionalist dilemma: the options that are politically viable are not democratically legitimate and the options that are democratically legitimate are not politically viable. Against the background of the recent Conference on the Future of Europe and the involvement of transnational European Citizens’ Panels, this article asks whether there is any prospect of overcoming this dilemma and organizing fundamental reform of EU institutions that is both normatively legitimate and politically viable. For this, it examines four models of EU treaty reform and the way these have figured in actual EU reform processes: Intergovernmental Conference, European Convention, informal intergovernmentalism and a Citizens Convention. The article concludes that, as long as the European Union is best characterized as a ‘demoi-cracy’ in which political deliberation takes place primarily in national public spheres, the Intergovernmental Conference remains its main and inevitable forum for constitutional reform. Hence, alternative models of EU constitutional reform should be evaluated not so much on the basis of their potential to substitute the IGC but rather on their ability to catalyse the process and to pre-commit the member state governments.

Hong Kong presents a test case of China’s willingness to adapt Western liberal values of individual freedom and the rule of law in a corner of China. The Western model of governance, along with its common law system and capitalist economic system, has been permitted to operate side by side with the Chinese socialist system within the framework of Chinese sovereignty and the People’s Republic of China’s (PRC) political and legal system. The formation and implementation of the policy of ‘one country, two systems’ (OCTS) entail Chinese law-makers’ selective integration of international and Western rules of governance into the Hong Kong and China context to serve the interests of the PRC party regime. This article explores the approaches taken by the PRC to the governance of Hong Kong in light of the regime’s political and economic goals and how the Western concept of rule of law and autonomy is perceived and substantiated in terms of the communist ideology. The author argues that the intrinsic value of OCTS lies in seeking complementarity and coexistence between the Western liberal norms of governance and Chinese communist ideology, and that this intrinsic value should be upheld and remain in full force to serve as a normative consensus between China and the West.

This article introduces the concept of hegemonic constituent power to argue for a greater role for the people in the process of Irish reunification through the establishment of a constituent assembly. Hegemonic constituent power contends that, ideally, constituent power should be possessed by the people; however, descriptively, this is invariably not the case. Constituent power instead is best understood as the manifestation of hegemony – the dominant power base in a given legal order that legitimates and reinforces this power through institutions, prevailing ideas and culture. Hegemony performs an important function in descriptively explaining legitimacy formation while not necessarily conferring normative legitimacy on existing power structures or those who exercise constituent power. Legitimacy and illegitimacy are both embedded in this notion of hegemonic constituent power. This allows for constituent power to perform a legitimating function and its creative potential to be unleashed while still leaving space for critical contestation over how this power was exercised. In this way, hegemonic constituent power also seeks to address critiques of constituent power as enabling populism. The article then deploys this concept of hegemonic constituent power to argue that fears of invoking the will of the people in debates on Irish reunification are misplaced.
