This book is the result of a 4-year research project conducted at the Faculty of Law of the University of Luxembourg. It explores the legal value and enforceability of tax circulars and tax rulings in Luxembourg domestic law in light of the principle of legitimate expectations and related principles. After studying the historical roots of both interpretative acts, this research questions the level of protection taxpayers enjoy when relying on circulars and tax rulings and contains a review of decades of administrative case-law to assess the judicial discourse on taxpayers’ rights to certainty. This book further investigates the case of circulars and tax rulings that contain interpretations of tax laws that are contrary to the law (contra legem) and builds upon the existing normative framework to introduce proposals addressing issues of uncertainty and inequality taxpayers are likely to suffer when relying on such interpretative acts.

Time is a crucial dimension in the application of any law. In tax law, however, where an environment characterized by rapid change on the national, European, and international levels complicates the provision of accurate legal advice, timing is particularly sensitive. This book is the first to analyse the relationship between time and three key areas of tax: treaties, EU law, and constitutional law issues, such as legal certainty and individual rights. Among the numerous timing issues arising out of applying tax rules, the book addresses the following: – time limits within which relief must be requested; – statutes of limitation for claiming a tax refund; – transitional issues relating to changes in tax treaties; – attribution of profits and expenses to a moving or closed-down business; – effect of tax-related CJEU decisions and EU directives; – compliance of exit tax regimes with free movement; – limits of retroactivity under principles protected by the EU Charter and the ECHR; and – conflict between efficiency of taxation and individual rights. Derived from a recent conference organized by the prestigious ATOZ Chair for European and International Taxation at the University of Luxembourg, the book brings together contributions from leading tax experts from various areas of tax practice, academia, and the judiciary. Among other issues, the book notably expands on how economic theory can inform a constitutional analysis of the timing of taxation. There is no other work that concentrates so usefully on the difficulties associated with applying tax rules – whether arising from treaties, jurisprudence, or policy – to changing circumstances over time. This book will quickly prove itself to be an indispensable resource for European tax lawyers, policymakers, company counsels, and academics.

This book explores for the first time the legal status and effects of circulars and tax rulings issued by the Luxembourg tax authorities.

The preliminary reference procedure under Article 267 TFEU is the keystone of the EU judicial system and its legal order. Based on a dialogue between the Court of Justice and national courts, it is strictly linked to the protection of the rights that individuals derive from EU law. This book focuses on this procedure from the perspective of the right to effective judicial protection, in light of Article 19(1), second subparagraph, TEU and Article 47 of the Charter of Fundamental Rights of the EU. It explores the level of protection that is ensured to individuals in order to access to the Court of Justice through preliminary references on the validity of EU acts and on the interpretation of EU law. The book offers a threefold perspective on preliminary references, through an analysis of the case law of the Court of Justice itself, of the European Court of Human Rights in relation to Article 6(1) ECHR, and of the constitutional courts of Austria, Croatia, Czech Republic, Germany, Slovakia, Slovenia, and Spain, where the national courts’ refusals to refer can lead to the violation of national constitutional rights. It further investigates the obligations for Member States and national courts in the framework of the preliminary reference procedure and how the right to effective judicial protection affects them. The examination outlines the implications that could flow from the recognition of a right for individuals to have a question referred to the ECJ, as part of the right to effective judicial protection under EU law, in particular its nature and its enforcement. Building upon the existing system of sanctions for the violations of the obligation to submit a preliminary question, the book advances some proposals to rethink the current system of remedies.

This book is a compilation of contributions exploring the impact of the European Treaty provisions regarding state aid on Member States’ legislation and administrative practice in the area of business taxation. Starting from a detailed analysis of the European Courts’ jurisprudence on Art.107 TFEU the authors lay out fundamental issues – e.g. on legal concepts like “advantage”, “selectivity” and “discrimination” – and explore current problems – in particular policy and practice regarding “harmful” tax competition within the European Union. This includes the Member States’ Code of Conduct on business taxation, the limits to anti-avoidance legislation and the options for legislation on patent boxes. The European Commission’s recent findings on preferential “rulings” are discussed as well as the general relationship between international tax law, transfer pricing standards and the European prohibition on selective fiscal aids.
