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.

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in the use of ideal types allows for comparison of tax jurisdictions, without the risk that the comparison gets outdated.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.

There is a distinct place for legal doctrinal methods in legal-interdisciplinary research methodologies, but there is value to be had in expounding that place – in developing a deeper understanding, for instance, of what legal doctrinal analysis has to offer, wherein lies its limitations, and how it could work in concert with methods and theories from disciplinary areas other than law. This article offers such perspectives, based on experiences with an ‘advanced’ legal-interdisciplinary methodology, which facilitates a long-term study of the growing body of practice generated by citizen-driven, independent accountability mechanisms (IAMs) that are institutionally affiliated with multilateral development banks. The article demonstrates how legal doctrinal methods have contributed towards the design and development of a multipurpose IAM-practice database. This database constitutes the analytical platform of the research project and also facilitates the integration of various types of research questions, methods and theories.

In addition to (or sometimes rather than primarily) attributing it to water scarcity, water crisis has been described as a ‘crisis of governance’; with the word ‘crisis’ also indicating that water governance lacks (full) legitimacy. The article undertakes the task to analyse the current status of global water governance (GWG) from the perspective of two competing theories relating to the legitimacy of global governance, namely global constitutionalism (GC) and global administrative law (GAL). Having mapped the current legal framework of GWG from these two perspectives, it is discussed how these theories might shape GWG and how this shaping could contribute to solving the water crisis. In addition, it is also explored whether reading one of the most accepted proposals for legitimising global water governance, the concept of ‘integrated water resources management’ (IWRM), through the lenses of either GC or GAL would have an impact on how this concept is interpreted, and whether it can be a useful mechanism to address the water crisis. The use of two theories analysing the same subject matter provides interesting insights into global water governance and the nature of the water crisis as well as the relationship between these two theories.
