Marine war risk insurance fundamentally contemplates casualties caused by international conflict. Curiously, however, standard clauses also exclude cover and automatically terminate war risk policies in the event of an outbreak of war between a select group of historically powerful States: China, France, the United Kingdom, the United States and Russia. This article aims to demystify the origins of this five-powers clause and evaluate its prospective application through the lens of an emerging breed of confrontation among the world's major powers.

On 22 June 2022 the Bill of Rights Bill to replace the Human Rights Act 1998 was introduced to the United Kingdom (UK) Parliament. Just over a year later, it was withdrawn. This was not a minor update, as claimed by the Conservative government, but a wholesale revision of a fundamental feature of UK constitutional arrangements. Given that the UK has no codified constitution, it is not out of the ordinary for constitutional change to proceed via ordinary Act of Parliament. But what was unusual was the informal methods used by the government in its attempt to push through its bill of rights. Searching for a word or phrase to capture what happened over this time in the UK is difficult, not only because of the absence of a conventional method for constitutional change. Most scholarship focuses on formal rather than informal processes for amendment. The purpose of this article is therefore to make a contribution towards filling this gap by introducing the phrase ‘autocratic method’ to describe a particular method of constitutional change as opposed to its substance. Using existing scholarship, and examples from other States, a preliminary definition and essential features of the autocratic method are set out. Further detail is gained through a study of the attempted replacement of the Human Rights Act. Whilst the Bill of Rights Bill is no longer going ahead, this episode in UK constitutional history contains important lessons not just for the UK but for any State embarking on a process of constitutional change.

The Parties to the Paris Agreement have committed to communicate successive ‘nationally determined contributions’ (NDCs) to the global response to climate change. Each NDC is expected to reflect the Party's ‘highest possible ambition’ (HPA) on the mitigation of climate change. This article envisages the possibility of taking HPA seriously: that is, of approaching it as an effective legal standard. It shows that, in some circumstances, the HPA standard can help to assess whether a State has complied with due diligence obligations on climate change mitigation.

In the past decade, the practice of investor–State arbitral tribunals addressing investment protection in the context of armed conflict and military occupation has expanded. This has prompted a growing interest in the relationship between international investment law and international humanitarian law (IHL), two regimes with markedly different relationships to war—IHL more pragmatic and international investment law more idealistic. This article argues that, while its lack of pragmatism might render international investment law ineffective in changing how war is conducted, it is the regime under which States are most likely to be held liable for the conduct of war. This is a result of its more robust primary obligations, more effective enforcement mechanisms and large awards of damages. Nevertheless, comparing international investment law and IHL does also reveal some similarities—the legacy, it is argued, of a time when the laws of war were more about protecting private property and neutral commerce than civilians. Putting these two regimes together in this way exposes international law's uneven distribution of protection in war.

As the human right to a healthy environment is codified around the globe, some systems still lag behind. One noticeable straggler is the Council of Europe, which is currently undergoing its fourth attempt to recognize the right. This article examines the proposals tabled within this system in light of overarching debates about climate justice and environmental rights, before focusing specifically on the spatial and temporal limits of the European Convention on Human Rights (ECHR) and the institutional features of its Court. First, the article describes what the author sees as the current liminal moment in the development of human rights law, a time of transition in which established legal concepts can be questioned or reaffirmed. Second, it sketches recent proposals for locating and conceptualizing the right to a healthy environment within the Council of Europe. Evaluating different options, it makes the case for including this right in the ECHR. Third, the article discusses the right's potential to reshape the spatial and temporal limitations on legal subjectivity and Convention protections. These proposals come at a crucial time when the system's ability to protect human rights from environment-related impacts is being tested by climate litigation. The article understands these developments as interrelated and discusses whether current proposals could deliver on demands for climate justice by extending protection to future generations and for extraterritorial environmental impacts.

This article offers a reconstruction of how the Court of Justice of the European Union (EU) justifies the territorial scope of application of EU law. Scholarship on this issue tends to advocate for an expansive projection of EU norms in the pursuit of global values, subject to the external limits of public international law. This article will develop a critique of this approach by pointing to its underlying assumptions as to the territorial dimension of the EU's rule, the insoluble practical issues that it leads to, and the need to consider differently the EU's spatial identity and relation to the wider world. It will also be argued that, in fact, other case law sometimes already reflects an alternative vision, by imagining the EU implicitly, not as a ‘global actor’ promoting universal values, but as a concretely situated and spatially bounded community. It will be shown that this is so with the methodological help of private international law, and in particular three doctrines that are traditional to this discipline—the localisation of cross-border relations, international imperativeness, and the public policy exception. This will ultimately allow for a more sophisticated understanding of the EU's territory to emerge—irreducible to the physical coordinates of its acts of intervention, or the mere sum of the physical spaces under Member State sovereignty, but as a distinct space of social relations, informed and delineated by the particular axiology and structure of the EU legal system.

The characterisation, legal status and future of islands are increasingly prominent in international and legal affairs. This emerging ‘legal era of islands’ demands a clearer understanding of the multiple distinctive legal issues that islands, whether as sub-national political units or as the territory of continental or mainland States, raise. This article conducts the first contemporary study of these issues by examining the international and constitutional legal status of island territories. It finds that although the relationship between islands and mainland States is characterised by incredible diversity, island territories are pursuing a range of innovative strategies to preserve and protect their autonomy.

In November 2023 the United Nations (UN) General Assembly and Security Council elected (in one case, re-elected) five judges to the International Court of Justice. The electoral system is considered to be overly politicized and to pay lip service to the requirements that judges must be elected on the basis of their qualifications, regardless of their nationality, and that in the body as a whole, the representation of the main forms of civilization and the principal legal systems of the world should be assured. Several amendments to the system of nominations and elections have been proposed that would require a reform of the Court's Statute. This article proposes four measures that could be adopted without amending the Statute or encroaching on the prerogatives of national groups, UN organs or Member States: (1) ensure the representation of the principal legal systems, in part by promoting regional diversity on the bench; (2) remove the use of nationality as a factor in casual elections; (3) establish a vetting process and public hearings; and (4) promote a single vote for Security Council members. It argues that the measures proposed would lead to a change in the present culture of nominations and elections towards one that favours the qualification of the judges over political considerations.

This article offers a reconstruction and assessment of the emerging rebellion of European constitutional courts against the exceptionless supremacy of European Union (EU) law. It presents the ontological theories of supremacy and how the Court of Justice of the EU (CJEU) overcame the first two major challenges of its history: the existential challenge of canonizing the general doctrine of supremacy and the Solange challenge of national fundamental rights. It provides an account of the emerging ultra vires challenge, including its root cause and evolvement, and provides an assessment and sets out proposals. The article demonstrates that the crux of the matter is not the primacy of EU law but the interpretive primacy of the CJEU. It argues that the rebellion was triggered by the perception that the CJEU case law features a declining normative and an increasing policy character. The debate about the CJEU's evolutionary interpretation, in a certain sense, parallels US constitutional law's debate between originalism and the living constitution, with the difference that the EU is a pluralist legal order.

This article examines reactions to the South China Sea and Chagos Marine Protection Area arbitrations under the United Nations Convention on the Law of the Sea (UNCLOS), in particular concerns about the potential widening of Part XV jurisdiction and its impact on the dispute resolution system's consent basis. It argues that assessing the impact of such cases involves a characterization of both the function of Part XV and of international judges. Ultimately, it suggests that the best test of whether UNCLOS case law has gone too far is the reaction of States in designing dispute settlement under the new Agreement under UNCLOS on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction.

For societies transitioning from conflict to peace, the phenomenon of child soldiers poses significant challenges. These include quandaries associated with assisting in the reintegration of serving child soldiers, determining how to prevent future recruitment of child soldiers, and pursuing accountability of those who utilize child soldiers. In addition, questions are also raised as to whether and how child soldiers responsible for crimes committed during conflict are to be held to account. While no one mechanism or response can adequately and sufficiently address the multifaceted issues that arise, peace agreements, as foundational documents that serve as the blueprint for peacebuilding and the post-conflict State, can make a useful contribution to some or all of them. Drawing on all references to child soldiers in 77 peace agreements signed between 1990 and 2022, this article examines the ways in which peace agreements address the issue of child soldiers.

The Geneva Convention relative to the Protection of Civilian Persons in Time of War provides a practical and effective framework for the protection of civilians in international armed conflicts that has retained its relevance for 75 years since its adoption. As with all treaties, its ‘object and purpose’ has a concrete impact on how its terms are interpreted, giving insights into the ordinary meaning of the text and allowing the aim of the Convention to be fully realized. This article asks and answers a series of questions to elucidate the role of the object and purpose in treaty interpretation and how to identify the object and purpose of a given treaty before focusing on the specificities of international humanitarian law treaties. On that basis, it determines that the overall ‘object and purpose’ of the Convention is to protect civilians during armed conflict, including in circumstances where they are subject to permissible measures of control and security. The article then demonstrates how that ‘object and purpose’ assists with the resolution of specific, well-known interpretive dilemmas including the determination of protected status under the Convention and the application of provisions premised on the existence of a Protecting Power.

This article adopts a critical approach towards scholarship seeking to identify binding due diligence obligations for States in cyberspace. The article demonstrates that due diligence obligations are anchored in specific primary rules and are not a universal standalone source from which it is possible to derive binding obligations for all areas of activity. The consensus position of States in United Nations fora clearly determines that due diligence in cyberspace is a voluntary, non-binding norm of responsible State behaviour, and there is currently insufficient State practice and opinio juris to support the development of a customary rule containing binding due diligence obligations in cyberspace. Consequently, the article concludes that attempts to establish binding due diligence obligations in cyberspace constitute lex ferenda that may be understood as an interventionist attempt by scholars to fill what they perceive to be dangerous legal gaps.

Since the 1960s sign languages have been identified as natural human languages and conceived of as a key feature of Deaf culture and identity. Eschewing the notion of disability, deaf advocacy organisations have connected the use of sign language to linguistic and cultural rights. Despite the clear preference of deaf advocates, the legal protection of sign languages remains uneven and somewhat difficult to grasp, being situated at the intersection of disability rights and linguistic rights. Few attempts have been made to identify the extent to which sign languages are recognised and enshrined within domestic legal systems. This article aims to propose a novel taxonomy that focuses on the normative conceptualisation of sign language and deaf people in national legislation. Based on a comparative analysis and focusing on European Union Member States, it identifies three main approaches: an explicit ‘minority’ approach—ie the express recognition of deaf persons as a linguistic minority; a more nuanced ‘cultural approach’—which acknowledges sign language as autonomous language and provides for promotional measures; and a ‘disability’ approach—which mandates and/or promotes the use of sign language primarily as an accessibility measure.

The dichotomy between jurisdiction and admissibility developed in public international law has drawn much attention from arbitrators and judges in recent years. Inspired by Paulsson's ‘tribunal versus claim’ lodestar, attempts have been made to transpose the distinction from public international law to investment treaty arbitration, yielding a mixed reception from tribunals. Remarkably, a second leap of transposition has found firmer footing in commercial arbitration, culminating in the prevailing view of the common law courts in England, Singapore and Hong Kong that arbitral decisions on admissibility are non-reviewable. However, this double transposition from international law to commercial arbitration is misguided. First, admissibility is a concept peculiar to international law and not embodied in domestic arbitral statutes. Second, its importation into commercial arbitration risks undermining the fundamental notion of jurisdiction grounded upon the consent of parties. Third, the duality of ‘night and day’ postulated by Paulsson to distinguish between reviewable and non-reviewable arbitral rulings is best reserved to represent the basic dichotomy between jurisdiction and merits.

This article conducts an analytical review of the works of three prominent Thai comparative law professors: Professor Preedee Kasemsup, Professor Phijaisakdi Horayangkura and Professor Sanunkorn Sotthibandhu. Although influential in Thailand, their works are mostly in Thai and therefore have received little academic attention outside the kingdom. The authors argue that the works of these scholars have the potential to shine new light on comparative law theory and bring voices from the Global South to add fresh perspectives and contexts to a discipline dominated by scholars from the Global North. Moreover, this examination highlights the challenges that comparative law faces in freeing itself from this hegemony when using internally developed concepts and modes of questioning.

The relationship between scholarship and adjudication has attracted considerable attention in recent years, especially in those areas where significant academic expertise has been developed and academic scrutiny of decisions is common. Yet the role of scholars and scholarship in the context of the adjudicatory practices of the European Court of Human Rights (ECtHR) has remained palpably under-investigated. This article begins to fill this gap in the literature by carrying out the first large-scale empirical study of the use of scholarship by the ECtHR. The authors rely on a purpose-built dataset comprising all the citations made by the Grand Chamber of the Court in judgments and separate opinions appended to it. The study finds that the Court's majority uses scholarship for the purposes of reviewing facts and interpreting international and domestic law but does so rarely. The majority of the ECtHR does not use scholarship to interpret the European Convention on Human Rights or for persuasive purposes, unlike the individual Judges in their separate opinions. Indeed, individual Judges refer to scholarship more often, for more varied and arguably different purposes. This use, however, is inconsistent in terms of both frequency and the types of sources referred to.

This article explores the constitutional regulation of birthright ius soli citizenship in two Latin American countries which restrict access to citizenship for the children of foreigners deemed to be passing through the countries. Access to citizenship is a significant marker of membership, setting the boundaries of inclusion and exclusion within and across States. Choosing the cases of Chile and Colombia, this article uses historical, institutional and comparative analysis in order to excavate the evolving conceptions of citizenship in those two countries, with particular reference to the concepts of the ‘transient foreigner’ and of ‘domicile’. The case studies provide an excellent laboratory within which to examine the evolution of constitutional ideas of citizenship and ‘the people’. In Colombia, the outcome of the investigation shows that there is unlikely to be significant long-term change in the citizenship regime towards a more generalised acceptance of unconditional ius soli, notwithstanding the substantial shorter-term measures taken to accommodate the children of undocumented migrants from Venezuela and to respond to international pressure. In Chile, combined with other ongoing constitutional work in the citizenship space as part of a wider reform process, there may be a slow journey towards a different constitutional future for so-called ‘transient foreigners’ and others excluded within the State, but this is currently stalled. Chile has, however, introduced legislation cementing a more limited concept of ‘transient foreigner’, linking this work on citizenship to the wider domain of migration governance.

Constitutional courts operate under a framework of formal and informal rules. While formal rules have been extensively studied, our understanding of informal rules remains limited. Courts often rely on internal practices, traditions and unwritten customs developed over time, posing a significant challenge due to their hidden nature. Numerous constitutional courts lack detailed voting protocols in their statutes and internal regulations, leaving essential aspects to the court's discretion, such as, inter alia, the voting order, deliberation style, outcome versus issue voting and tie-breaking protocols. By employing a case study of strategic breaching of informal voting protocols in the Mexican Supreme Court, this article highlights the complexity of enforcing informal voting rules given that external actors may be unaware of them, along with other factors. Even when informal rules are broadly known, certain circumstances may diminish the efficacy of informal sanctions addressing their breach. Thus, key judicial players, such as chief justices or judge-rapporteurs, may take advantage of the informal rules of voting protocols to advance their policy preferences.

This article analyses the challenges that online marketplaces and e-commerce pose to traditional product liability doctrines. It uses a comparative perspective to examine whether an online platform can be liable to a consumer for a defective product purchased on its platform, and the adaption of product liability law to this challenge in a series of jurisdictions. It reflects on the role of litigation and regulation, focusing on Europe and the United States, and considers reform in a number of jurisdictions in this area. It concludes with proposals for increasing the accountability of online marketplaces for products sold on their websites.
