The International Institute for Conflict Prevention & Resolution (CPR) has a long history of helping people consider more thoughtful and collaborative ways of preventing and resolving disputes. One of their vehicles for doing so is a series of pledges.

When the time comes to select a mediator, the judge, the lawyers, the parties or the mediation centre will want to find a good one. This raises two questions: what is a good mediator and how to find one?
The answer to the first question seems rather simple: a good mediator is one that the parties are happy with. This raises another set of questions: if the parties were happy with a mediator in one case, would they be happy with the same person in another case? Would other parties be happy with this mediator as well? If the answers are not a yes without reservation to both of those questions, then the question becomes: who would be a good mediator for this case between these parties?

In ‘The Enemy of All Humanity’, David Luban provides an insightful and plausible account of the idea of the hostis generis humani (one that shows that the hostis need not be understood to be an outlaw), and of the distinctive character of the crimes against humanity that the hostis commits. However, I argue in this paper, his suggestion that the hostis is answerable to a moral community of humanity (in whose name the ICC must thus claim to speak) is not tenable. Once we recognize the intimate connection between criminal law and political community, we can see that the hostis should answer to the local, domestic political community in and against which he commits his crimes; and that the proper role of the International Criminal Court, acting in the name of the community of nations, is to provide a second-best substitute for such answering when the local polity cannot or will not hold him to account.

This article discusses empirical examples from international trial transcripts to see if and why there is a need to use the ‘enemy of all humanity’ label in contemporary international criminal justice discourse. It shows an absence of explicit uses of the concept and an ambiguous set of implicit references; the hosti generis humani concept is simultaneously too precise and too broad for ICJ discourse. Based on these findings, the article challenges David Luban’s suggestion that the term can be undone from its dehumanizing potential and used adequately in the ICJ context.

Antony Duff, Marc de Wilde, Louis Sicking, and Sofia Stok offer several criticisms of my “The Enemy of All Humanity,” but central to all of them is concern that labeling people hostis generis humani dehumanizes them, and invites murder or extrajudicial execution. In response I distinguish political, legal, and theoretical uses of the ancient label. I agree with the critics that the political use is toxic and the legal use is dispensable. However, the theoretical concept is crucial in international criminal law, which rests on the assumptions that the moral heinousness of core crimes makes them the business of all humanity. Furthermore, far from dehumanizing their perpetrators, calling them to account before the law recognizes that they are no different from the rest of humanity. This response also offers rejoinders to more specific objections raised by the critics.

In his contribution to this special issue, David Luban proposes to revive the age-old concept of ‘the enemy of all humanity.’ On his view, this concept supports the aims of international criminal justice by emphasizing that atrocity and persecution crimes are ‘radically evil’ and therefore ‘everyone’s business.’ Criticizing Luban’s proposal, this paper shows that in the past, the ‘enemy of all humanity’ concept has often served to establish parallel systems of justice, depriving these ‘enemies’ of their rights as suspects under criminal law and as lawful combatants under the laws of war. Thus, even if the ‘enemy of all humanity’ concept is used with the intention to bring today’s perpetrators of ‘radical evil’ to justice, it risks undermining, rather than protecting, the rule of law.

Introducing the special issue, we point out how the notion of an ‘enemy of all humanity’ challenges the very foundations of international (criminal) law. We also give an overview of the other contributions.

Piracy holds a special place within the field of international law because of the universal jurisdiction that applies. This article reconsiders the role of piracy in the development of universal jurisdiction. While usually a connection is established between Cicero’s ‘enemy of all’ and modern conceptions of pirates, it is argued that ‘enemy of the human species’ or ‘enemy of humanity’ is a medieval creation, used by Bartolus, which must be understood in the wake of the Renaissance of the twelfth century and the increased interest for the study of Roman Law. The criminalization of the pirate in the late Middle Ages must be understood not only as a consequence of royal power claiming a monopoly of violence at sea. Both the Italian city-states and the Hanse may have preceded royal power in criminalizing pirates. All the while, political motives in doing so were never absent.

Trationally, the term “enemy of all humanity” (hostis generis humani) referred to pirates. In contemporary international criminal law, it refers to perpetrators of crimes against humanity and other core. This essay traces the evolution of the concept, and then offers an analysis that ties it more closely to ancient tyrants than to pirates. Some object that the label is dehumanizing, and justifies arbitrary killing of the “enemy of humanity.” The essay admits the danger, but defends the concept if it is restricted to fair trials. Rather than dehumanizing its target, calling the hostis generis humani to account in a court of law is a way of recognizing that radical evil can be committed by humans no different from any of us.

This article discusses how the law has approached disparate socio-technological innovations over the centuries. Precisely, the primary concern of this paper is to investigate the timing of regulatory intervention. To do so, the article makes a selection of particular innovations connected with money, windmills and data storage devices, and analyses them from a historical perspective. The individual insights from the selected innovations should yield a more systematic view on regulation and technological innovations. The result is that technological changes may be less momentous, from a regulatory standpoint, than social changes.

This article presents a perspective which focuses on the right to access information as a mean to ensure a non-discriminatory character of algorithms by providing an alternative to the right to explanation implemented in the General Data Protection Regulation (GDPR). I adopt the evidence-based assumption that automated decision-making technologies have an inherent discriminatory potential. The example of a regulatory means which to a certain extent addresses this problem is the approach based on privacy protection in regard to the right to explanation. The Articles 13-15 and 22 of the GDPR provide individual users with certain rights referring to the automated decision-making technologies. However, the right to explanation not only may have a very limited impact, but it also focuses on individuals thus overlooking potentially discriminated groups. Because of this, the article offers an alternative approach on the basis of the right to access information. It explores the possibility of using this right as a tool to receive information on the algorithms determining automated decision-making solutions. Tracking an evolution of the interpretation of Article 10 of the Convention for the Protection of Human Right and Fundamental Freedoms in the relevant case law aims to illustrate how the right to access information may become a collective-based approach towards the right to explanation. I consider both, the potential of this approach, such as its more collective character e.g. due to the unique role played by the media and NGOs in enforcing the right to access information, as well as its limitations.

In this paper I propose to analyse the binary notion of personal data and highlight its limits, in order to propose a different conception of personal data. From a risk regulation perspective, the binary notion of personal data is not particularly fit for purpose, considering that data collection and information flows are tremendously big and complex. As a result, the use of a binary system to determine the applicability of EU data protection law may be a simplistic approach. In an effort of bringing physics and law together, certain principles elaborated within the quantum theory are surprisingly applicable to data protection law, and can be used as guidance to shed light on many of today’s data complexities. Lastly, I will discuss the implications and the effects that certain processing operations may have on the possibility of qualifying certain data as personal. In other terms, how the chances to identify certain data as personal is dependent upon the processing operations that a data controller might put in place.

In recent years, there has been growing policy support for expanding worker ownership of businesses in the European Union. Debates on stimulating worker ownership are a regular feature of discussions on the collaborative economy and the future of work, given anxieties regarding the reconfiguration of the nature of work and the decline of standardised employment contracts. Yet, worker ownership, in the form of labour-managed firms such as worker cooperatives, remains marginal. This article explains the appeal of worker cooperatives and examines the reasons why they continue to be relatively scarce. Taking its cue from Henry Hansmann’s hypothesis that organisational innovations can make worker ownership of firms viable in previously untenable circumstances, this article explores how organisational innovations, such as those embodied in the capital and governance structure of Decentralised (Autonomous) Organisations (D(A)Os), can potentially facilitate the growth of LMFs. It does so by undertaking a case study of a blockchain project, Colony, which seeks to create decentralised, self-organising companies where decision-making power derives from high-quality work. For worker cooperatives, seeking to connect globally dispersed workers through an online workplace, Colony’s proposed capital and governance structure, based on technological and game theoretic insight may offer useful lessons. Drawing from this pre-figurative structure, self-imposed institutional rules may be deployed by worker cooperatives in their by-laws to avoid some of the main pitfalls associated with labour management and thereby, potentially, vitalise the formation of the cooperative form.

These days, it appears to be common ground that what is illegal and punishable offline must also be treated as such in online formats. However, the enforcement of laws in the field of hate speech and fake news in social networks faces a number of challenges. Public policy makers increasingly rely on the regu-lation of user generated online content through private entities, i.e. through social networks as intermediaries. With this privat-ization of law enforcement, state actors hand the delicate bal-ancing of (fundamental) rights concerned off to private entities. Different strategies complementing traditional law enforcement mechanisms in Europe will be juxtaposed and analysed with particular regard to their respective incentive structures and consequential dangers for the exercise of fundamental rights. Propositions for a recommendable model honouring both pri-vate and public responsibilities will be presented.

This article highlights the Singapore judiciary’s experience in introducing an online filing and case management system with Online Dispute Resolution (ODR) for small value disputes to improve access to justice. This system, called the Community Justice & Tribunals System (CJTS), is a fully integrated justice solution, allowing parties to settle their disputes and obtain a court order online. The article sets out the issues and challenges encountered in developing CJTS, the innovative solutions implemented and CJTS’ positive impact on litigants-in-person.
