The principle of non-discrimination plays a vital role in international and European tax law. This dissertation analyses the interpretation given to that principle in tax treaty practice and in the direct tax case law of the Court of Justice of the European Union (ECJ) on the fundamental freedoms. The objective of this analysis is twofold: to give a clear and thorough overview of both standards and to determine whether they share a common, underlying principle of non-discrimination. In order to achieve these objectives, a comprehensive selection of case law is discussed from the perspective of the two constitutive elements of discrimination, comparability and the existence of different treatment. Moreover, attention is drawn to the question whether a domestic measure that is found to be discriminatory may nevertheless be justified on the basis of reasons of public interest. Finally, the possible interplay between both standards is addressed.

In any democratically constituted regime, the real value of the principle of equality can be measured in a very revealing way: by evaluating the consistency and impartiality of tax legislation and its judicial review. Such an evaluation, using a comparative approach to applicable law in several European jurisdictions, is essentially what this book provides. The six authors, a supreme court justice, a professional tax consultant, a tax inspector, and three tax law academics, treat such crucial issues as the following: national variations in the extent of judicial power to review tax legislation; discriminatory tax legislation arising as a response to interest group pressures; the European Convention on Human Rights as the basis for the development of a fully operational principle of equality; the degree of appreciation that should be accorded the democratically legitimized legislature by the judiciary; the obligation to provide actual redress to victims of discrimination; and, the effect of the principle of freedom of establishment on the rules of international tax law. The authors refer throughout to all relevant sources of applicable law, including national constitutions, legislation, and case law; the EC Treaty and the European Convention on Human Rights; and the case law of the European Court of Justice and the European Court of Human Rights. Clearly a valuable work for tax practitioners and policymakers, Legal Protection against Discriminatory Tax Legislation will also be appreciated by professionals and officials concerned with the complex day-to-day ramifications of the principles of equality and non-discrimination in European society.

This book provides a comprehensive and systematic overview of the main topics of taxation in European law. The sequence of arguments follows an institutional logic, respecting the academic tradition of tax law. It first outlines the general framework of EU institutions, with a particular focus on the set of regulations regarding taxation with reference to the stage of formation of EU rules and the potential contrast with national legal systems. It then explores the general principles emerging from the European treaties that typically involve the taxation system, and examines in detail the fiscal importance of European freedoms, the principle of tax non-discrimination, the balance between national interest and EU values, tax harmonization, state aids and other general principles applicable in tax jurisdiction. Lastly, it offers an overall assessment of the development of the European integration process, with particular regard to the nexus between taxation power and sovereignty, in order to highlight the possible and desirable next stages of the evolution of “European tax law”.

Non-discrimination is a central obligation under both tax treaty and trade law. However, in seeking to strike a balance between national and international interests, its application differs in the two areas of practice. This deeply researched and authoritative work, which explains the policy issues and how non-discrimination analysis works, provides a comprehensive review of non-discrimination rules in WTO and tax treaty law, combining a critical commentary on case law with proposals for an innovative concept for solving cases of discrimination in tax treaty law. Among the practical issues affecting non-discrimination examined in detail are the following: implications that can be drawn from the concepts of non-discrimination under WTO law and Article 24 of the OECD Model; direct and indirect discrimination and analysis of comparability in WTO law and tax treaty law; the MFN and NT rules under the GATT and GATS; the meaning of ‘likeness’ and ‘less favourable treatment’; claiming non-discriminatory tax treatment before tax administrations and courts under a tax treaty; justification of measures against harmful tax competition, low taxation and hybrid mismatch arrangements; thin capitalisation rules, progressive tax rates, foreign losses, group taxation and relief from juridical and economic double taxation under Article 24 of the OECD Model; and integrating a justification defence into any stage of a non-discrimination analysis. The author establishes to what extent formal, substantive and subjective approaches may be applied in a non-discrimination analysis, providing the reasons for the approaches taken. A two-step comparability procedure is applied to selected cases of potential tax discrimination, demonstrating how policy arguments can be addressed under Article 24 of the OECD Model. Drawing on over a half-century of case law in both areas of practice, this comprehensive study of the non-discrimination rules under WTO law and international tax law will be invaluable in systematically solving cases of tax discrimination under Article 24 of the OECD Model and putting forward arguments at any stage of a WTO analysis. Policymakers will benefit from the author’s clear explanation of how national law should comply with international obligations. Also, taxpayers’ advisers will proceed confidently in claims of tax treaty discrimination, and academics will discover an incomparable overview and analysis of anti-discrimination rules in international trade law and double taxation conventions.
