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 article offers a reflection on how applications of computer technology (including data analytics) are and may be taught to (future) lawyers and what are the benefits and limitations of the different approaches. There is a growing sense among legal professionals and law teachers that the technological changes in the practice of law are likely to promote the kind of knowledge and skills that law graduates often do not possess today. Teaching computer technology can be done in various ways and at various depths, and those different ways and levels have different cost and benefit considerations. The article discusses four models of teaching technology: (1) teaching basic technological literacy, (2) more advanced but general technology teaching, (3) teaching computer programming and quantitative methods and (4) teaching a particular aspect of technology – other than programming (e.g. cybersecurity). I suggest that there are strong reasons for all current and future lawyers to acquire proficiency in effective uses of office and legal research software and standard means of online communication and basic cybersecurity. This can be combined with teaching of numerical and informational literacy. I also claim that advanced technology topics, like computer programming, should be taught only to the extent that this is justified by the direct need for such skills and knowledge in students’ future careers, which I predict to be true for only a minority of current lawyers and law students.

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 French ‘Code de procédure pénale’ provides the possibility to revise final criminal convictions. The Act of 2014 reformed the procedure for revision and introduced some important novelties. The first is that it reduced the different possible grounds for revision to one ground, which it intended to broaden. The remaining ground for revision is the existence of a new fact or an element unknown to the court at the time of the initial proceedings, of such a nature as to establish the convicted person’s innocence or to give rise to doubt about his guilt. The legislature intended judges to no longer require ‘serious doubt’. However, experts question whether judges will comply with this intention of the legislature. The second is the introduction of the possibility for the applicant to ask the public prosecutor to carry out the investigative measures that seem necessary to bring to light a new fact or an unknown element before filing a request for revision. The third is that the Act of 2014 created the ‘Cour de révision et de réexamen’, which is composed of eighteen judges of the different chambers of the ‘Cour de cassation’. This ‘Cour de révision et de réexamen’ is divided into a ‘commission d’instruction’, which acts as a filter and examines the admissibility of the requests for revision, and a ‘formation de jugement’, which decides on the substance of the requests. Practice will have to show whether these novelties indeed improved the accessibility of the revision procedure.

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 Belgian Code of criminal procedure provides the possibility to revise final criminal convictions. This procedure had remained more or less untouched for 124 years, but was finally reformed by the Act of 2018, after criticism was voiced in legal doctrine concerning its narrow scope and possible appearances of partiality and prejudice. The Act of 2018 therefore broadened the third ground for revision, the so-called novum, and defined it as an element that was unknown to the judge during the initial proceedings and impossible for the convicted person to demonstrate at that time and that, alone or combined with evidence that was gathered earlier, seems incompatible with the conviction, thus creating a strong suspicion that, if it had been known, it would have led to a more favourable outcome. Thereby, this ground for revision is no longer limited to factual circumstances, but also includes changed appreciations by experts. To counter appearances of partiality and prejudice, the Act of 2018 created the Commission for revision in criminal matters, a multidisciplinary body that has to give non-binding advice to the Court of Cassation on the presence of a novum. However, the legislature also introduced new hurdles on the path to revision, such as the requirement for the applicant to add pieces that demonstrate the ground for revision in order for his or her request to be admissible. For that reason, the application in practice will have to demonstrate whether the Act of 2018 made the revision procedure more accessible in reality.

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.

According to the traditional view, the ultimate aim of the extraordinary review (recurso de revisión) provided in the Spanish justice system was to deal with wrongful criminal convictions and correct those serious miscarriages of justice which became apparent only after the judgment had become final. However, the 2015 reform called this traditional view into question by formally including two additional grounds for review that are not necessarily related to the correcting miscarriages or blatant mistakes in the assessment of the facts made by the sentencing court. This paper aims to give an overview of the extraordinary review in Spain. To that end it will first address the legal framework and its practical implementation, as well as present pitfalls and best practices. Finally, future trends and challenges will be identified in order to improve the protection of defendants who have suffered a wrongful conviction.

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.
