This article explores how sovereignty fictions have been used to advance different legal, political and economic aims in the articulation of the United Kingdom's future approach to global regulation. By mapping the transformative shifts in sovereignty paradigms, this article highlights the disconnect between the absolutist sovereignty popularised in the UK government's political rhetoric and the concept of regulatory sovereignty that underpins the UK's future trading strategy. To maintain its status as a global leader in regulation and standards-setting, the UK government will need to diffuse power and delegate autonomy through networked orders of public and private actors. These competing sovereignty paradigms are analysed with reference to European Union (EU) law and practice, to highlight the opportunities and challenges for the UK as an independent trade actor. This article concludes by evaluating how sovereignty fictions can disrupt the objectives of the UK's proposed ‘common law’ approach to regulatory governance and discusses the policy interventions that may be required to enable the UK to harness its potential as a regulatory leader.

Under the International Health Regulations (IHR), States must consider decision-making criteria in applying travel restrictions during a public health emergency of international concern. Interpretation on the legal parameters of such restrictions varies widely. This article considers whether and how the permissibility of travel restrictions under the IHR may have changed given recent developments, including evolving scientific evidence about their efficacy and shifting World Health Organization (WHO) advice. It is argued that such determinations must conform to the principles of necessity and proportionality as articulated by the IHR, and must also be accompanied by the correlative IHR duties of collaboration and assistance rooted substantively in global solidarity.

This article makes a case for an international convention on expert determination (ED) and Dispute Boards (DBs) that would require its Contracting States to recognise agreements on ED/DBs and enforce ED/DB decisions. Whilst strong, the case for the convention may not be compelling as there are arguments against it. But at least the time has come for the international legal community to start thinking about and debating the need for such an international regime. This article takes the first step towards imagining this international regime by evaluating a number of key issues relating to its scope of application.

Article 16 of the Ireland–Northern Ireland Protocol annexed to the EU–UK Withdrawal Agreement is an escape clause which allows the parties to deviate from their obligations under certain conditions. This article maps out the main features of the safeguards provision in the Protocol in light of international trade law and international relations literature on treaty design. It provides a detailed examination of the safeguards provision in the Protocol and highlights the key design flaws associated with this regime as well as some potential solutions to such flaws.

In 2021, unconstitutional transfers of power in Myanmar and Afghanistan highlighted that while States may desire a coherent response to questions about the status of governments, and may look for international guidance in such regard, there is no established process for providing such guidance. Thus, attention focuses on the General Assembly's credentials process, designed to assess the eligibility of delegates to represent their States at the UN. This article proposes that rather than the credentials process being stretched in this way, greater use should be made of the Assembly's competence to pass determinative resolutions on government legitimacy.

The forgotten story of the birth and life of the definition of ‘military objectives’ is relevant to the ongoing discussion about the need to adapt the law to asymmetric warfare. This definition, authored by a West German law professor and former member of the Nazi party, was driven by a Western effort to privilege regular armies while curbing the actions of guerrilla fighters and exposing their civilian supporters to harm. The Non-Aligned Movement turned the tide by burdening regular armies while exempting irregular combatants from the consequences of disregarding the law. It was only through judicial intervention—grounded in an imagined history of the linear progress of humanity—that civilians on both sides of asymmetric conflicts would ultimately become entitled to receive adequate protection.

This article assesses the arguments and challenges that are likely to arise should investors file an investor–State dispute settlement (ISDS) claim over measures taken in response to a waiver of obligations relating to intellectual property rights (IPRs) under the World Trade Organization's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement). After providing an overview of the proposed waiver of IPRs for COVID-19 vaccinations and treatments, it examines the jurisprudence relating to IP and investor–State arbitration and the grounds upon which investors would rely to make a case in ISDS and possible State defences. The analysis, which focuses on fair and equitable treatment and expropriation, concludes that it will be difficult for investors to succeed in claiming that measures taken in response to a TRIPS waiver of IPRs breach any substantive protection provision contained in an international investment agreement. States should, however, seek additional security by revisiting existing treaties and adding additional layers of safeguards to ensure legitimate and non-discriminatory measures taken in response to a TRIPS waiver do not lead to investor claims.

In September 2021, the French Cour de Cassation reversed the annulment that the Paris Cour d'appel earlier had granted in regard to an arbitral award in Alexander Brothers v Alstom on grounds of corruption. This brought French courts in line with their English counterparts, at least in that one case, the latter having accepted the Alexander Brothers award as enforceable. Noteworthy beyond the welcome consistency that the recent French judgment imparts in one case, that and other recent judgments cast light on several issues in international arbitration, including the arbitrability of allegations of fraud or corruption, the relevance of evidence of corruption ‘downstream’ from a contract, and the legal effects (if any) on third parties of internal compliance regimes that enterprises adopt in response to national regulatory and enforcement actions in respect of corruption.

This article challenges the widely held view that WTO Members are not permitted to impose trade restrictions on other WTO Members in the form of countermeasures for breaches of international law. It cautions that this generally held view has wider implications for international law and multilateralism because countermeasures are a significant means of enforcing and preserving the normative integrity of international obligations outside the WTO, including erga omnes and erga omnes partes obligations. Arguments supporting their ‘displacement’ must be based on clear evidence, which this article shows to be lacking. This article also attempts to allay the (understandable but perhaps exaggerated) concern that such countermeasures might undermine the predictability of the WTO system. Trade countermeasures for breaches of extra-WTO obligations are subject to stringent conditions under customary international law and to judicial scrutiny by means of WTO adjudication, both of which minimise the space for abuse and the risk of unpredictability.

The article tests the claim of feminist scholars that concerns about gender have been marginalised in refugee law, by exploring the interpretation given to the concept of a ‘Particular Social Group’ set out in the 1951 Refugee Convention. It is argued that recent practice at the supranational level in the European Union has contributed to the deterioration of refugee protection standards for women seeking asylum from gender-based violence. However, the article demonstrates that a human rights-based approach to the interpretation of ‘Particular Social Group’, which is supported by extensive examples of good practice in individual Member States, has the potential to redress this.

This article analyses the fraught relationship between host States’ obligations under investment agreements and their regulatory powers in the field of public health. First, tribunals addressing the merits of health measures have exercised considerable deference to States under existing treaties. Second, the recent generation of treaties spells out health considerations to encourage respondents or tribunals to adopt broad interpretations of the right to regulate, general exceptions, or article-specific carve-outs. Clauses modelled on GATT exceptions may prove difficult to invoke due to the ‘necessity’ threshold. Finally, the Kyoto Protocol may serve as a model of incentivising private investment in the public health sector.

The International Law Commission's 2019 Draft Conclusions on Peremptory Norms of International Law assert that States have an obligation to cooperate to end serious breaches of peremptory norms. International law provides scarce guidance, however, regarding how States are expected to fulfil that obligation. This article seeks to elaborate: first, whether the prohibition of crimes against humanity and the ‘basic rules’ of international humanitarian law are peremptory norms; second, what States are required to do to fulfil their obligation to cooperate; and third, how States might utilise the General Assembly as a forum through which to fulfil that obligation.

Relying on examples from international, EU and comparative law and drawing on insights from the class action literature, this article argues that important advances in minority rights protection can be achieved without the revision of substantive legal provisions and the full-scale embracing of collective rights. Allowing minority members to present their claims on behalf of a larger group (collective procedure), even when such claims ultimately rest on the rights of individuals as opposed to those of the group, strengthens minority rights and can transform our vision of them. An overview of eight interrelated benefits shows not only how these advantages occur, but also why the procedural approach avoids the issues that motivate negative critiques of group rights.

This article consists of a comparative study of the basic principles underlying the rules of jurisdiction in private international law in commercial cases in the law of the European Union, the United States and England. It considers the objectives which these rules seek to achieve (protection of the rights of the parties and respect for the interests of foreign States) and the extent to which these objectives are attained. It takes tort claims, especially in the field of products-liability, as an example and considers which system has the most exorbitant rules. It suggests explanations for the differences found.

European private international law has long been recognised as improperly set up to deal with cross-border collective redress. In light of this shortcoming, it seems unfortunate that the private international law implications of the Representative Actions Directive (Directive (EU) No 2020/1828) have not yet been addressed coherently by the European legislator. This article examines to what extent the policy of promoting collective redress can be supported, even if only partially, through a reinterpretation of the jurisdictional rules of the Brussels Ia Regulation. Furthermore, it discusses which legislative measures need to be adopted to better accommodate collective redress mechanisms within the Brussels regime.

With the constant flow of data across jurisdictions, issues regarding conflicting laws and the protection of rights arise. This article considers the EU–US data transfer relationship in the aftermath of the decision in Data Protection Commissioner v Facebook Ireland and Maximillian Schrems where the Court of Justice of the European Union (CJEU) invalidated an EU–US data transfer agreement for the second time in just five years. This judgment continues the line of cases emphasising the high value the Court places on securing EU personal data in accordance with EU data protection standards and fundamental rights. This article assesses the implications of the ruling for the vulnerable EU–US data transfer relationship.

Few court cases in the history of European integration have been more controversial than the decisions of the Court of Justice of the EU and the German Federal Constitutional Court on the European Central Bank's public sector asset purchase programmes. This article regards consistency and coherence in the case law as uncontroversial minimum conditions that have to be satisfied for the decisions to gain legitimacy. It assesses the case law against this benchmark and determines the limits of asset purchase programmes under a consistent and coherent application of the legal tests developed by the courts.

This article analyses the European Union's competences in the energy sector. It focuses on Article 194(2) of the Treaty on the Functioning of the European Union, which affords EU Member States the right to determine the conditions for exploiting their energy resources, the choice between different energy sources and the general structure of their energy supply. This article traces the constitutional development of EU competences in the energy sector to demonstrate the relevance of Article 194(2) TFEU in the current constitutional, international and sector-specific contexts of EU energy law. It analyses the recent case law of the Court of Justice of the European Union, which shows that the scope of Article 194(2) TFEU is considerably narrower in practice than its wording implies. The article concludes by evaluating the implications of this narrow interpretation on the future development of EU energy law and, in a broader context, on the reach of EU energy and climate policy.

The definition of the crime of aggression in Article 8 bis of the Rome Statute of the International Criminal Court (Rome Statute) stipulates that a State act of aggression is a material element of the crime, suggesting an intrinsic link between individual criminal responsibility and State responsibility for aggression. This article argues that the Rome Statute provides a legal basis for the International Criminal Court (ICC) to determine State responsibility for aggression when considering the material elements of the crime of aggression, which has important practical and conceptual implications for the law of international responsibility. Although the content of State responsibility flows automatically from the breach of the obligation, it is argued that a finding of aggression pursuant to Article 8 bis of the Rome Statute may be considered as a form of satisfaction for the purposes of Article 37 of the 2001 ILC Articles on Responsibility of States for Internationally Wrongful Acts (2001 ILC Articles). Furthermore, the material element of the crime in Article 8 bis of the Rome Statute requires the act of aggression by its character, gravity, and scale to constitute a manifest violation of the Charter of the United Nations, in line with the nomenclature used within the 2001 ILC Articles regarding serious breaches of obligations arising from peremptory norms of general international law (jus cogens). The article considers the important role that the ICC may play in relation to serious breaches of the jus cogens obligation to refrain from an act of aggression.

As the gatekeeper of international law, the CJEU determines the effects not only of international agreements but also decisions of compliance review bodies. This article analyses the Court's engagement with rulings of the WTO dispute settlement bodies (DSB) and findings of the Aarhus Convention Compliance Committee (ACCC). These case studies demonstrate the varied toolkit used by the CJEU to forge relationships with external regimes, while maintaining the EU's autonomy. The CJEU considers DSB reports and ACCC findings selectively and implicitly, demonstrating a qualified openness to international law and a reluctance to engage in a meaningful dialogue with international quasi-judicial bodies.
