The change of circumstances impacting the performance of the contracts has been a widely commented issue. However, there seems to be a gap in legal jurisprudence with regard to resorting to such a remedy in the investment contracts setting, especially from the procedural perspective. It has not been finally settled whether arbitral tribunals are empowered to adapt investment contracts should circumstances change and, if they were, what the grounds for such a remedy would be. In this article, the author presents the current debates regarding this issue, potential grounds for application of such a measure and several proposals which would facilitate resolution of this procedural uncertainty.

Long before the coming of the Bill of Rights in written Constitutions, the common law has had the greatest regard for the personal liberty of the individual. In order to safeguard that liberty, the remedy of habeas corpus was always available to persons deprived of their liberty unlawfully. This ancient writ has been incorporated into the modern Constitution as a fundamental right and enforceable as other rights protected by virtue of their entrenchment in those Constitutions. This article aims to bring together the various understanding of habeas corpus at common law and the principles governing the writ in common law jurisdictions. The discussion is approached through a twelve-point construct thus providing a brief conspectus of the subject matter, such that one could have a better understanding of the subject as applied in most common law jurisdictions.

This article presents an interdisciplinary comparison of British and German legal arguments concerning the justification of the use of force against the Islamic State in Iraq and Syria (ISIS). It is situated in the broader framework of research on strategic culture and the use of international law as a tool for justifying state behaviour. Thus, a gap in political science research is analysed: addressing legal arguments as essentially political in their usage. The present work questions whether differing strategic cultures will lead to a different use of legal arguments. International legal theory and content analysis are combined to sort arguments into the categories of instrumentalism, formalism and natural law. To do so, a data set consisting of all speeches with regard to the fight against ISIS made in both parliaments until the end of 2018 is analysed. It is shown that Germany and the UK, despite their varying strategic cultures, rely on similar legal justifications to a surprisingly large extent.

The interpretive techniques applied by the European Court of Human Rights are instrumental in filling the vaguely formulated rights-provisions with progressive content, and their use provoked widespread criticism. The article argues that despite the scarcity of explicit references to the Vienna Convention on the Law of Treaties, all the ECtHR’s methods and doctrines of interpretation have basis in the VCLT, and the ECtHR has not developed a competing framework. The Vienna rules are flexible enough to accommodate the interpretive rules developed in the ECHR jurisprudence, although effectiveness and evolutive interpretation is favoured – due to the unique nature of Convention – over the more traditional means of interpretation, such as textualism. Applying the VCLT as a normative framework offers unique ways of reconceptualising some of the much-contested means of interpretation in order to increase the legitimacy of the ECtHR.

Many questions facing legal scholars and practitioners can be answered only by analysing and interrogating large collections of legal documents: statutes, treaties, judicial decisions and law review articles. I survey a range of novel techniques in machine learning and natural language processing – including topic modelling, word embeddings and transfer learning – that can be applied to the large-scale investigation of legal texts

The adoption of big data analysis in the legal domain is a recent but growing trend that highlights ethical concerns not just with big data analysis, as such, but also with its deployment in the legal domain. This article systematically analyses five big data use cases from the legal domain utilising a pluralistic and pragmatic mode of ethical reasoning. In each case we analyse what happens with data from its creation to its eventual archival or deletion, for which we utilise the concept of ‘data life cycle’. Despite the exploratory nature of this article and some limitations of our approach, the systematic summary we deliver depicts the five cases in detail, reinforces the idea that ethically significant issues exist across the entire big data life cycle, and facilitates understanding of how various ethical considerations interact with one another throughout the big data life cycle. Furthermore, owing to its pragmatic and pluralist nature, the approach is potentially useful for practitioners aiming to interrogate big data use cases.

Computational analysis can be seen as the most recent innovation in the field of Empirical Legal Studies (ELS). It concerns the use of computer science and big data tools to collect, analyse and understand the large and unstructured data, such as for instance (legal) text. Given that the text is now the object of analysis, but the methods are (largely) quantitative, it lies in the intersection between doctrinal analysis and ELS. It brings with it not only a great potential to scale up research and answer old research questions, but also to reveal uncovered patterns and address new questions. Despite a slowly growing number of legal scholars who are already applying such methods, it is underutilised in the field of law. Furthermore, given that this method comes from social and computer sciences, many legal scholars are not even aware of its existence and potential. Therefore, the purpose of this special issue is not only to introduce these methods to lawyers and discuss possibilities of their application, but also to pay special attention to the challenges, with a specific emphasis on the ethical issues arising from using ‘big data’ and the challenge of building capacity to use such methods in law schools. This editorial briefly explains some of the methods which belong to the new movement of Computational Legal Analysis and provides examples of their application. It then introduces those articles included in this special issue. Finally, it provides a personal note on the way forward for lawyers within the movement of Computational Legal Analysis

The article presents the status quo of the law of retrial in Germany and gives an overview of the law and practice of the latter in favour of the convicted and to the disadvantage of the defendant. Particularly, the formal and material prerequisites for a successful petition to retry the criminal case are subject to a detailed presentation and evaluation. Because no official statistics are kept regarding successful retrial processes in Germany, the actual number of judicial errors is primarily the subject of more or less well-founded estimates by legal practitioners and journalists. However, there are a few newer empirical studies devoted to different facets of the subject. These studies will be discussed in this article in order to outline the state of empirical research on the legal reality of the retrial procedure. Against this background, the article will ultimately highlight currently discussed reforms and subject these to a critical evaluation as well. The aim of the recent reform efforts is to add a ground for retrial to the disadvantage of the defendant for cases in which new facts or evidence indicate that the acquitted person was guilty. After detailed discussion, the proposal in question is rejected, inter alia for constitutional reasons.

Wrongful convictions and miscarriages of justice, their reasons and effects, only rarely become the subject of academic debate in Poland. This article aims at filling this gap and providing a discussion on the current challenges of mechanisms available in Polish law focused on the verification of final judgments based on innocence claims. While there are two procedures designed to move such judgment: cassation and the reopening of criminal proceedings, only the latter aims at the verification of new facts and evidence, and this work remains focused exactly on that issue. The article begins with a case study of the famous Komenda case, which resulted in a successful innocence claim, serving as a good, though rare, example of reopening a case and acquitting the convict immediately and allows for discussing the reasons that commonly stand behind wrongful convictions in Poland. Furthermore, the article examines the innocence claim grounds as regulated in the Polish criminal procedure and their interpretation under the current case law. It also presents the procedure concerning the revision of the case. The work additionally provides the analysis of the use of innocence claim in practice, feeding on the statistical data and explaining tendencies in application for revision of a case. It also presents the efforts of the Polish Ombudsman and NGOs to raise public awareness in that field. The final conclusions address the main challenges that the Polish system faces concerning innocence claims and indicates the direction in which the system should go.

Since 1997, the Criminal Cases Review Commission of England, Wales and Northern Ireland has served as a state-funded post-conviction body to consider claims of wrongful conviction for those who have exhausted their rights to appeal. A meticulous organisation that has over its lifetime referred over 700 cases back to the Court of Appeal, resulting in over 60% of those applicants having their convictions quashed, it is nonetheless restricted in its response to cases by its own legislation. This shapes its decision-making in reviewing cases, causing it to be somewhat deferential to the original jury, to the principle of finality and, most importantly, to the Court of Appeal, the only institution that can overturn a wrongful conviction. In mandating such deference, the legislation causes the Commission to have one eye on the Court’s evolving jurisprudence but leaves room for institutional and individual discretion, evidenced in some variability in responses across the Commission. While considerable variability would be difficult to defend, some inconsistency raises the prospects for a shift towards a less deferential referral culture. This article draws on original research by the author to consider the impact of institutional deference on the work of the Criminal Cases Review Commission and argues for a slightly bolder approach in its work

The Italian Constitution expressly contemplates the possibility of a wrongful conviction, by stating that the law shall determine the conditions and forms regulating damages in case of judicial error. Therefore, it should come as no surprise that many provisions of the Italian Code of Criminal Procedure (CCP) deal with the topic. The aim of this article is to provide an overview of the post-conviction remedies in the Italian legal system by considering the current provisions of the CCP, on the one hand, and by exploring their practical implementation, on the other.

This article reviews exoneration in Sweden, with a focus on the procedure of applying for exoneration. First, it highlights some core features of Swedish criminal procedural law, necessary to understand exoneration in the Swedish context. Secondly, it outlines the possibilities in Swedish law to apply for exoneration, both in favour of a convicted person and to the disadvantage of a previously acquitted defendant. Thirdly, it identifies some challenges with the current Swedish model of administering applications for exoneration. Fourthly, it argues that the current system should be reformed by introducing into Swedish law a review committee that administers applications for exoneration.

The Dutch legislature has recently (2012) altered the legislation for post-conviction revision of criminal cases. The legislature aimed to improve the balance between the competing interests of individual justice and the finality of verdicts, by making post-conviction revision more accessible. In this article we describe the current legal framework for revising cases. We also study how the revision procedure functions in practice, by looking at the types and numbers of (successful) requests for further investigations and applications for revision. We observe three challenges in finding the right balance in the revision process in the Netherlands. These challenges concern: 1) the scope of the novum criterion (which is strict), 2) the appropriate role of an advisory committee (the ACAS) in revision cases (functioning too much as a pre-filter for the Supreme Court) and, 3) the difficulties that arise due to requiring a defence council when requesting a revision (e.g., financial burdens).

States apply different material conditions to attract or restrict residence of certain types of migrants. But states can also make use of time as an instrument to design more welcoming or more restrictive policies. States can apply faster application procedures for desired migrants. Furthermore, time can be used in a more favourable way to attract desired migrants in regard to duration of residence, access to a form of permanent residence and protection against loss of residence. This contribution makes an analysis of how time is used as an instrument in shaping migration policy by the European Union (EU) legislator in the context of making migration more or less attractive. This analysis shows that two groups are treated more favourably in regard to the use of time in several aspects: EU citizens and economic- and knowledge-related third-country nationals. However, when it comes to the acquisition of permanent residence after a certain period of time, the welcoming policy towards economic- and knowledge-related migrants is no longer obvious.

A question that has preoccupied sociolegal scholars for ages is whether law can change ‘hearts and minds’. This article explores whether non-discrimination law can create social change, and, more particularly, whether it can change attitudes and beliefs as well as external behaviour. The first part examines how sociolegal scholars have theorised about the possibility and desirability of using law as an instrument of social change. The second part discusses the findings of empirical research on the social working of various types of non-discrimination law. What conclusions can be drawn about the ability of non-discrimination law to create social change? What factors influence this ability? And can non-discrimination law change people’s hearts and minds as well as their behaviour? The research literature does not provide an unequivocal answer to the latter question. However, the overall picture emerging from the sociolegal literature is that law is generally more likely to bring about changes in external behaviour and that it can influence attitudes and beliefs only indirectly, by altering the situations in which attitudes and opinions are formed.

International human rights law (IHRL) was established in the aftermath of the Second World War to prevent a reoccurrence of the atrocities committed in the name of fascism. Central to this aim was the recognition that out-groups are particularly vulnerable to rights violations committed by the in-group. Yet, it is increasingly apparent that out-groups are still subject to a wide range of rights violations, including those associated with mass atrocities. These rights violations are facilitated by the dehumanisation of the out-group by the in-group. Consequently, this article argues that the creation of IHRL treaties and corresponding monitoring mechanisms should be viewed as the first step towards protecting out-groups from human rights violations. By adopting the lens of dehumanisation, this article demonstrates that if IHRL is to achieve its purpose, IHRL monitoring mechanisms must recognise the connection between dehumanisation and rights violations and develop a positive State obligation to counter dehumanisation. The four treaties explored in this article, the European Convention on Human Rights, the International Covenant on Civil and Political Rights, the Framework Convention for the Protection of National Minorities and the International Convention on the Elimination of all forms of Racial Discrimination, all establish positive State obligations to prevent hate speech and to foster tolerant societies. These obligations should, in theory, allow IHRL monitoring mechanisms to address dehumanisation. However, their interpretation of the positive State obligation to foster tolerant societies does not go far enough to counter unconscious dehumanisation and requires more detailed elaboration.

This article argues that it is legitimate for the state to practice soft paternalism towards changing hearts and minds in order to prevent behaviour that is discriminatory. Liberals accept that it is not legitimate for the state to intervene in order to change how people think because ideas and beliefs are wrong in themselves. It is legitimate for the state to intervene with the actions of a person only when there is a risk of harm to others and when there is a threat to social coexistence. Preventive action of the state is legitimate if we consider the immaterial and material harm that discrimination causes. It causes harm to the social standing of the person, psychological harm, economic and existential harm. All these harms threaten peaceful social coexistence. This article traces a theory of permissible government action. Research in the areas of behavioural psychology, neuroscience and social psychology indicates that it is possible to bring about a change in hearts and minds. Encouraging a person to adopt the perspective of the person who has experienced discrimination can lead to empathetic understanding. This, can lead a person to critically evaluate her prejudice. The paper argues that soft paternalism towards changing hearts and minds is legitimate in order to prevent harm to others. It attempts to legitimise state coercion in order to eliminate prejudice and broader social patterns of inequality and marginalisation. And it distinguishes between appropriate and non-appropriate avenues the state could pursue in order to eliminate prejudice. Policies towards eliminating prejudice should address the rational and the emotional faculties of a person. They should aim at using methods and techniques that focus on persuasion and reduce coercion. They should raise awareness of what prejudice is and how it works in order to facilitate well-informed voluntary decisions. The version of soft paternalism towards changing minds and attitudes defended in this article makes it consistent with liberalism.

In this article, we focus on how the education system can be used to promote equality in the context of changing people’s hearts and minds – values, morals and mindsets. The duties contained in the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 (‘Equality Act’) bind private and public schools, educators, learners, governing bodies and the state. The Equality Act calls on the state and all persons to promote substantive equality, but the relevant sections in the Equality Act have not been given effect yet, and are therefore currently not enforceable. We set out how the duty to promote equality should be concretised in the Equality Act to inter alia use the education system to promote equality in schools; in other words, how should an enforceable duty to promote equality in schools be fashioned in terms of the Equality Act. Should the relevant sections relating to the promotion of equality come into effect in their current form, enforcement of the promotion of equality will take the form of obliging schools to draft action plans and submit these to the South African Human Rights Commission. We deem this approach inadequate and therefore propose certain amendments to the Equality Act to allow for a more sensible monitoring of schools’ duty to promote equality. We explain how the duty to promote equality should then play out practically in the classroom to facilitate a change in learners’ hearts and minds.
