This paper uses Stoic theory of language to gain more insight into Roman lawyer Proculus’s legal opinions on the meaning and understanding of ambiguous testaments, wills and dowries. After summarizing Stoic theory of language, the paper discusses its reception in Roman jurisprudence and situates Proculus in a Stoic legal/philosophical context. The meat of the article lies in the re-examination of Proculus’s legal opinions on ambiguities in light of Stoic theory of language, through: (1) the analysis of a case demonstrating that Proculus’s embeddedness in Stoic doctrine went beyond his technical competence in propositional syllogisms, going into the territory of Stoic physical materialism and, (2) the investigation of four cases that reveal how his approach to problems of ambiguity in unilateral legal acts converges with the Stoic conception of the parallelism between speech and thought.

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.

The European Union single market needs to tackle an outstanding issue to boost competitiveness and growth: a trust-based redress framework that ensures the effectiveness of consumers’ rights. The current disparities among dispute resolution mechanisms, added to the fact that in practice many do not guarantee participation and enforceability, are serious obstacles to this goal. Trust and the integration of certain dispute avoidance tools added to the regulation of some common enforcement mechanisms are key issues in the field of consumer protection. The goal of this article is to offer some insights within the context of the European Union legislative proposals aimed at improving the current redress system.

This article discusses two underrated and connected aspects that determine the applicability of the EU Charter on Fundamental Rights to Member State measures. First, the Charter can be a decisive standard of review for domestic measures only when they are covered by EU law but are not precluded by it. In this respect, the distinction between non-preclusion and non-application of EU law has been overlooked by legal scholarship. Second, because the scope of application of EU law and that of the Charter are identical, the latter suffers from the same uncertainties as the former. This article concludes that the entry into force of the Charter has exposed the blurred contours of the application of EU law, in particular in the area of the market freedoms. As a result, a certain spontaneous harmonization of human rights protection has emerged.

The global financial crisis of 2008 and the following public uproar over offshore tax evasion and corporate aggressive tax planning scandals gave rise to unprecedented international cooperation on tax information exchange and coordination on corporate tax reforms. At the behest of the G20, the OECD developed a comprehensive package of ‘consensus-based’ policy reform measures aimed to curb base erosion and profit shifting (BEPS) by multinationals and to restore fairness and coherence to the international tax system. The legitimacy of the OECD/G20 BEPS Project, however, has been widely challenged. This paper explores the validity of the legitimacy concerns raised by the various stakeholders regarding the OECD/G20 BEPS Project.

The emergence of global tax governance was triggered by common tax problems, which are now still being faced by international society of nation-states. In the creation of this framework, international institutions have been playing a major role. One of these institutions is the World Bank (Bank). However, those who write about the virtues and vices of the main creators of the framework usually disregard the Bank. This article, therefore, argues that this disregard is not justified because the Bank has also been playing a prominent role. Since two informal decisions taken in the past have contributed to this position of the Bank, the article gives in addition to it answers to the following two related questions: whether these informal decisions of the Bank were legal and if so, what implications, if any, they have for the Bank’s legitimacy.

This article evaluates the recently completed Base Erosion and Profit Shifting (BEPS) project of the G20 and OECD and offers some alternatives for reform.

The OECD BEPS Action 6 report contains a principal purpose test rule (PPT rule) for the purpose of combating abuse of tax treaties. This PPT rule is also included in the OECD Multilateral Instrument.
The PPT rule is (amongst others) applicable when ‘it is reasonable to conclude’ that a benefit (granted by a tax treaty) was one of the principal purposes of any arrangement/transaction. This requirement contains two elements: the reasonableness test and the principal purpose test.
In literature it is observed that (i) the reasonableness test of the PPT rule could be contrary to the European Union’s principle of legal certainty; (ii) that the OECD PPT rule gives the tax authorities too much discretion and, therefore, is not in line with EU law and (iii) there is doubt whether the OECD PPT rule contains a genuine economic activity test and therefore is in contravention of the abuse of law case law of the CJEU.
In this contribution, I defend that none of the above-mentioned reasons the OECD PPT rule is contrary to EU law. The only potential problem I see is that the OECD PPT rule is broader (no artificiality required) compared to the GAARs in Anti-Tax Avoidance Directive and the Parent–Subsidiary Directive.

The international tax system is the result of the interaction of different actors who share the responsibility for its integrity. States and multinational corporations both enjoy to a certain extent freedom of choice with regard to their tax behaviour – which entails moral responsibility. Making, interpreting and using tax rules therefore is inevitably a matter of exercising responsibility. Both should abstain from viewing tax laws as a bunch of technical rules to be used as a tool without any intrinsic moral or legal value. States bear primary responsibility for the integrity of the international tax system. They should become more reticent in their use of tax as regulatory instrument – competing with one another for multinationals’ investment. They should also act more responsibly by cooperating to make better rules to prevent aggressive tax planning, which entails a shift in tax payments from very expert taxpayers to other taxpayers. Here, the distributive justice of the tax system and a level playing field should be guaranteed. Multinationals should abstain from putting pressure on states and lobbying for favourable tax rules that disproportionally affect other taxpayers – SMEs and individual taxpayers alike. Multinationals and their tax advisers should avoid irresponsible conduct by not aiming to pay a minimalist amount of (corporate income) taxes – merely staying within the boundaries of the letter of the law. Especially CSR-corporations should assume the responsibility for the integrity of the tax system.

The aim of this article is to examine the differences in perception of ‘fairness’ between developing and developed countries, which influence developing countries’ willingness to embrace the Base Erosion and Profit Shifting (BEPS) proposals and to recommend as to how to overcome these differences. The article provides an introduction to the background of the OECD’s BEPS initiatives (Action Plan, Low Income Countries Report, Multilateral Framework, Inclusive Framework) and the concerns of developing countries about their ability to implement BEPS (Section 1); a non-exhaustive overview of the shortcomings of the BEPS Project and its Action Plan in respect of developing countries (Section 2); arguments on why developing countries might perceive fairness in relation to corporate income taxes differently from developed countries (Section 3); and recommendations for international organisations, governments and academic researchers on where fairness in respect of developing countries should be more properly addressed (Section 4).

In a much publicised case, Uber drivers have won a first instance employment tribunal finding that they are ‘workers’ and not self-employed contractors. This decision means that they are entitled to basic protections, such as the national minimum wage, paid holiday (under the Working Time Directive) and protection against detriment for ‘blowing the whistle’ on wrong doing. The decision could have substantial financial consequences for Uber, which has around 40,000 drivers in the UK but Uber has already confirmed that it will appeal the decision, so we are unlikely to have a final determination on this question for some time.

Tax law may, in principle, allow persons aged under 30 to deduct from their taxable income more vocational training expenses than older persons.

The number of comparative tax law studies is substantial. The available literature on the methodology behind these tax comparisons, however, is rather limited and underdeveloped. This article aims to contribute to the theoretical background of tax comparisons by explicating methodological considerations in a comparative tax research on tax incentives for cross-border donations and relating it to the available methodological literature. Two aspects of tax law make comparative research in tax law a challenging endeavour: its complexity and fast-changing nature. To overcome these issues, this article proposes to divide jurisdictions into a limited number of categories. In this process the different legal levels are analysed systematically, resulting in categories of jurisdictions. Among the jurisdictions in one category, common characteristics are identified. This results in an abstract description of the category. I use the term ‘ideal types’ for these categories. The high level of abstraction in the use of ideal types allows for comparison of tax jurisdictions, without the risk that the comparison gets outdated. An additional advantage of working with ideal types is that the conclusions of the comparison can be applied to all jurisdictions that fit in the ideal type. This increases the generalisability of the conclusions of the comparative tax research.

The damages actions reform of the European Union is predetermined to fail in achieving its stated goal of full compensation. There are two main reasons for this. First, the Directive on damages actions fails to maintain a balance between the claims of direct and indirect purchasers. Second, the EU policy is not designed to collect a large group of antitrust victims, who have suffered only a low-value harm (e.g., end consumers). The only way to achieve compensation effectiveness is to overstep the bounds of the EU compensatory regime, which is trapped in the grip of conservatism. In such circumstances, this article will explore three forceful scenarios of collective redress that include different types of deterrence-based remedies. The principal aim is to assess the chances of these scenarios in achieving full compensation. After assessing them, the best possible mechanism for compensating victims will be designed. In turn, it will allow the evaluation of to what extent such a scheme can ensure the achievement of full compensation.

The UK Supreme Court has held that the mistreatment of two Nigerian employees based on their vulnerable immigration status, did not amount to direct or indirect discrimination. The question for the Court was whether the employees had been discriminated against on the basis of their nationality. The Court accepted that immigration status is a function of nationality, but that it is not the same thing.

The Supreme Court in this case establishes conditions to be met in order for the member of a Board of Directors to qualify as a self-employed “entrepreneur”. In light of these conditions, Directors must be considered to have the status of “individual contractor”, obligating them to pay increased social security contributions.

In this article I develop a political realist notion of public reason. It may be thought that a notion of public reason is simply incompatible with the position of the political realist. But this article claims that a realist notion of public reason, different from the familiar political liberal idea of public reason, can be reconstructed from ancient texts on rhetoric and dialectic, particularly Aristotle's. The specification of this notion helps us understand the differences between contemporary liberal and realist positions.
