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.

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.

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.

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).

This article seeks to examine the development of positive obligations under European law in the specific context of the rights of sexual minorities. It is clear that the law should respect and protect all sexualities and diverse intimate relationships without discrimination, and for this purpose it needs to ensure that sexual minorities can not only be free from state interference when expressing their sexuality in private, but that they should be given the right to express their sexuality in public and to have their intimate relationships legally recognised. In addition, sexual minorities should be protected from the actions of other individuals, when these violate their legal and fundamental human rights. Accordingly, in addition to negative obligations, European law must impose positive obligations towards sexual minorities in order to achieve substantive equality for them. The article explains that, to date, European law has imposed a number of such positive obligations; nonetheless, there is definitely scope for more. It is suggested that European law should not wait for hearts and minds to change before imposing additional positive obligations, especially since this gives the impression that the EU and the European Court of Human Rights (ECtHR) are condoning or disregarding persistent discrimination against sexual minorities.

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.

The article analyses the jurisprudence of international tribunals on the education and housing of Roma and Travellers to understand whether positive obligations can change the hearts and minds of the majority and promote minority identities. Case law on education deals with integration rather than cultural specificities, while in the context of housing it accommodates minority needs. Positive obligations have achieved a higher level of compliance in the latter context by requiring majorities to tolerate the minority way of life in overwhelmingly segregated settings. Conversely, little seems to have changed in education, where legal and institutional reform, as well as a shift in both majority and minority attitudes, would be necessary to dismantle social distance and generate mutual trust. The interlocking factors of accessibility, judicial activism, European politics, expectations of political allegiance and community resources explain jurisprudential developments. The weak justiciability of minority rights, the lack of resources internal to the community and dual identities among the Eastern Roma impede legal claims for culture-specific accommodation in education. Conversely, the protection of minority identity and community ties is of paramount importance in the housing context, subsumed under the right to private and family life.

The entry into force of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) pushed state obligations to counter prejudice and stereotypes concerning people with disabilities to the forefront of international human rights law. The CRPD is underpinned by a model of inclusive equality, which views disability as a social construct that results from the interaction between persons with impairments and barriers, including attitudinal barriers, that hinder their participation in society. The recognition dimension of inclusive equality, together with the CRPD’s provisions on awareness raising, mandates that states parties target prejudice and stereotypes about the capabilities and contributions of persons with disabilities to society. Certain human rights treaty bodies, including the Committee on the Rights of Persons with Disabilities and, to a much lesser extent, the Committee on the Elimination of Discrimination against Women, require states to eradicate harmful stereotypes and prejudice about people with disabilities in various forms of interpersonal relationships. This trend is also reflected, to a certain extent, in the jurisprudence of the European Court of Human Rights. This article assesses the extent to which the aforementioned human rights bodies have elaborated positive obligations requiring states to endeavour to change ‘hearts and minds’ about the inherent capabilities and contributions of people with disabilities. It analyses whether these bodies have struck the right balance in elaborating positive obligations to eliminate prejudice and stereotypes in interpersonal relationships. Furthermore, it highlights the convergences or divergences that are evident in the bodies’ approaches to those obligations.

Islamophobia, like xenophobia, points to deep-seated, ingrained discrimination against a particular group, whose effective enjoyment of fundamental rights is impaired. This in turn triggers the human rights obligations of liberal democratic states, more particularly states’ positive obligations (informed by reasonability considerations) to ensure that fundamental rights are effectively enjoyed, and thus also respected in interpersonal relationships. This article identifies and compares the fault lines in the practice of three international human rights supervisory mechanisms in relation to Islamophobia, namely the Human Rights Committee (International Covenant on Civil and Political Rights), the European Court of Human Rights (European Convention on Human Rights) and the Advisory Committee of the Framework Convention for the Protection of National Minorities. The supervisory practice is analysed in two steps: The analysis of each international supervisory mechanism’s jurisprudence, in itself, is followed by the comparison of the fault lines. The latter comparison is structured around the two main strands of strategies that states could adopt in order to counter intolerance: On the one hand, the active promotion of tolerance, inter alia through education, awareness-raising campaigns and the stimulation of intercultural dialogue; on the other, countering acts informed by intolerance, in terms of the prohibition of discrimination (and/or the effective enjoyment of substantive fundamental rights). Having regard to the respective strengths and weaknesses of the supervisory practice of these three international supervisory mechanisms, the article concludes with some overarching recommendations.

This article considers how empirical legal studies (ELS) and doctrinal legal research (DLR) interact. Rather than seeing them as competitors that are methodologically independent and static, it suggests that they are interdependent activities, which may each be changed by interaction with the other, and that this change brings both opportunities and threats. For ELS, the article argues that DLR should properly be understood as part of its theoretical framework, yet in practice little attention is given to doctrine in empirical work. Paying more attention to DLR and legal frames generally would help ELS meet the common criticism that it is under-theorised and excessively policy oriented. On the other hand, an embrace of legal thinking, particularly of critical legal thinking, might lead to loss of status for ELS in policy circles and mainstream social science. For DLR, ELS offers a chance for it to escape the threat of insular sterility and irrelevance and to participate in a founded commentary on the world. The risk, however, is that in tailoring legal analysis to what can be empirically researched legal scholars become less analytically ambitious and more safe, and their traditionally important role as a source of socially relevant critique is weakened. Inevitably, in offering different ways of moving to normative conclusions about the law, ELS and DLR pose challenges to each other, and meeting those challenges will require sometimes uncomfortable self-reflection.
