Niamh Nic Shuibhne, The Coherence of EU Free Movement Law: Constitutional Responsibility and the Court of Justice, (Oxford University Press, 2013)
Abstract: At the heart of the European Union is the establishment of a European market grounded in the free movement of people, goods, services, and capital. The implementation of the free market has preoccupied European lawyers since the inception of the Union's predecessors. Throughout the Union's development, as obstacles to free movement have been challenged in the courts, the European Court of Justice has had to expand on the internal market provisions in the founding Treaties to create a body of law determining the scope and meaning of the EU protection of free movement. In doing so, the Court has often taken differing approaches across the different freedoms, leaving a body of law apparently lacking a coherent set of foundational principles.This book presents a critical analysis of the European Courts' jurisprudence on free movement, examining the Court's constitutional responsibility to articulate a coherent vision of the EU internal market. Through analysis of restrictions on free movement rights, it argues that four main drivers are distorting the system of the case law and its claims to coherence. The drivers reflect 'good' impulses (the protection of fundamental rights); avoidable habits (the proliferation of principles and conflicting lines of case law authority); inherent ambiguities (the unsettled purpose and objectives of the internal market); and broader systemic conditions (the structure of the Court and its decision-making processes). These dynamics cause problematic instances of case law fragmentation - which has substantive implications for citizens, businesses, and Member States participating in the internal market as well as reputational consequences for the Court of Justice and for the EU more generally. However, ultimately the Member States must take greater responsibility too: only they can ensure that the Court of Justice is properly structured and supported, enabling it to play its critical institutional part in the complex narrative of EU integration.Examining the judicial development of principles that define the scope of EU free movement law, this book argues that sustaining case law coherence is a vital constitutional responsibility of the Court of Justice. The idea of constitutional responsibility draws from the nature of the duties that a higher court owes to a constitutional text and to constitutional subjects. It is based on values of fairness, integrity, and imagination. A paradigm of case law coherence is less rigid, and therefore more realistic, than a benchmark of legal certainty. But it still takes seriously the Court's obligations as a high-level judicial institution bound by the rule of law. Judges can legitimately be expected - and obliged - to be aware of the public legal resource that they construct through the evolution of case law.

Niamh Nic Shuibhne, Laurence Gormley, From Single Market to Economic Union: Essays in Memory of John A Usher, (Oxford University Press, 2012)
Abstract: The path from single market to economic union is a continuing — and controversial — story; raising questions about the present and future regulation, structures, and purpose of economic union within the broader objectives of the EU legal and political order. This book focuses on the evolution and regulation of the EU as an economic union, in tribute to the scholarship of the late Professor John A Usher. The process of treaty reform within the EU has now reached fruition and attention is being re-focused on substantive aspects of EU law and policy. The chapters in the collection consider the EU internal market in its broadest sense: the fundamental free movement provisions remain at the core, but the concept of the transnational market must also accommodate competing interests to which the EU is committed but the implications of which can nonetheless distort, and thus need to be carefully balanced within, the basic free trade framework (for example, intellectual property rights and the protection of innovation, and also the implementation of social policy objectives). The book also situates the market in its broader politico-economic context. The global economic climate remains precarious and questions about optimal financial and fiscal regulation, and monetary stability, remain critically significant, especially in a transnational context given the degree of inter-dependency generated by the EU integration project.

Niamh Nic Shuibhne, Michael Dougan, Eleanor Spaventa, Empowerment and Disempowerment of the European Citizen, (Hart Publishing, 2012)
Abstract: This collection of essays engages with a central theme in scholarship on EU citizenship – the emancipation of certain citizens, the alienation of others – and seeks to expand its horizons to interrogate whether similar debates and trends can be identified in other fields of European integration. The focus of the book is distinctly citizen focused. It delivers the potential for the opening out of analysis of the implications of European citizenship beyond the parameters of Articles 18-25 TFEU and beyond the disciplinary confines of legal analysis alone. The book construes 'EU citizenship' in its broadest sense, and explores the extent to which the European citizen is, or indeed is not, genuinely at the heart of EU law and policy-making. What is the purpose and role of this transnational, regional regulator, given that citizen concerns seem focused primarily at either the infra State or global levels? Within the broader theme of empowerment and disempowerment, the contributors reflect on a range of cross-cutting themes; for example, the extent to which channels of citizen participation (can) inform EU policy-making in a 'bottom-up' sense; or whether the EU is a catalyst for the construction of new spaces and new identities.

Niamh Nic Shuibhne, Regulating the Internal Market, (Edward Elgar Publishing, 2006)
Abstract: This collection explores the management of the internal market from a legal perspective. While the EU agenda is currently dominated by the processes of Treaty reform, this assessment of both market and constitutional governance evaluates the coherence or otherwise of the project at the very core of European integration. Confronted with a free market nearing completion, with a relatively formulaic application of internal market law, the book portrays how this is mirrored in a growing tendency to hand the market 'back' to the Member States and, increasingly, to authorities and bodies (both public and private) therein. We see too, however, an internal market framework that strains to cope with a series of challenges, both internal and external to the EU itself. The approach of the contributors is two-fold - on one hand, they reflect thematically on questions of regulation which cut across the spectrum of the market and its freedoms. On the other hand, they adopt more sector-specific lenses (including, for example, regulation of the media and the Internet) through which contemporary regulatory dynamics can be reconsidered. Providing analysis of contemporary challenges facing the internal market, this book will be of great interest to academics, researchers and students working in the field of EC law. It will also strongly appeal to national and community officials and policy makers due to its 'testing' abstract questions of principle surrounding constitutional character in the market sphere.

Niamh Nic Shuibhne, EC Law and Minority Language Policy: Culture, Citizenship and Fundamental Rights, (Kluwer, 2002)
Abstract: The European Community has pledged respect for the cultural and linguistic diversity of its Member States and has recognized minority languages as an inherent constituent in this regard. This development reflects a broader trend within the Community towards grappling with less obvious aspects of supranational governance. Minority language groups turn optimistically to Europe in response. But, despite rhetorical promises, just what can the EC actually be expected to do in the realm of minority language protection, a politically sensitive and traditionally domestic concern? Arguments put forward to date focus primarily on philosophical, moral, economic, and political discourse. While these considerations are a vital aspect of the debate on minority languages and on linguistic diversity more generally, the question of legal basis remains largely unanswered. This book traces comprehensively the existence of an appropriate legal basis for action undertaken by the EC in this domain, striving in particular to locate a pragmatic yet effective balance between legitimate possibility and acceptable limitations.


Niamh Nic Shuibhne, 'Limits rising, duties ascending: The changing legal shape of Union citizenship', (2015), Common Market Law Review, Vol 52, pp 889-937
Abstract: This article demonstrates that there has been a generational shift towards the rising significance of conditions and limits, and a less explicit but discernible ascension of duties, in the application and interpretation of citizenship rights. Articles 20 and 21 TFEU provide for the restriction of rights by both primary and secondary law, but the extent to which this now occurs calls into question the existence, and not just the exercise, of the foundational primary rights. The article argues that there has been a hegemonic attribution of supremacy to secondary law that fails to engage the constitutional protocols epitomizing the Union legal order more generally.

Niamh Nic Shuibhne, Marsela Maci, 'Proving Public Interest: The Growing Impact of Evidence in Free Movement Case Law', (2013), Common Market Law Review, Vol 50, pp 965-1005
Abstract: When national measures restrict free movement rights, Member States can argue that their actions are,nevertheless, justifiable and proportionate. But how do they actually demonstrate this? This article explores the standard that Member States must satisfy to prove their public interest claims successfully. It will be argued that a critical information gap on what the Court of Justice expects defendant States to establish has been narrowed through a more concerted focus on proof in recent case law; but that significant issues still demand further attention. While an evolving guidance framework can be pieced together by extracting key principles from relevant - especially more recent - case law, it is questionable whether this is sufficient for national courts and lawyers. The fact that more attention is being placed on proof and evidence in recent case law, however, also raises questions about the value or even propriety of applying a veneer of empiricism over the many complexities involved in adjudicating on public interest choices. As a case study, the article discusses the difficulty of unpicking economic arguments from public interest claims. It is suggested, overall, that knowing an appropriate standard of proof has to be reached is one thing; but knowing what it is and how to reach it is something else entirely.

Niamh Nic Shuibhne, 'Case Comment on Kik v Office for Harmonisation in the Internal Market ', (2004), Common Market Law Review, Vol 41, pp 1093-1111
Abstract: The rubric of a European Union in which Member States unite in their diversities is firmly sewn into the ideology of European integration; and the composite multilingualism of the EU is an obvious badge of diversity. Both the ideology and the multilingual reality must, however, find appropriate weightings in an equation of linguistic balance - a formula comprising: 1. culture and fundamental rights, 2. efficiency and economy, 3. communication and representation, 4. differentiation, 5. diversity, 6. progress and tradition, 7. preservation and innovation, and 8. participation, citizenship, governance, and respect. But for present purposes, the questions provoked by these competing values will be concentrated on just one aspect of EU language functions - the rules that govern the EU administration. In a series of 4 cases, it was sought to establish that the EU institutions have got the balance wrong.

Abstract: The European Community has pledged respect for the cultural and linguistic diversity of its Member States and has recognised minority languages as an inherent constituent in this regard. In turn, minority language groups turn to "Europe" in response to grapple with minority language issues when perhaps domestic response to their concerns is either not forthcoming or simply not enough. This paper submits, however, that while there is a justifiable role for EC involvement in minority language issues, this competence is necessarily limited by the function and capacity of the EC more generally.

Abstract: In considering how localized consumer tastes have to comply with the requirements set by both regional and national production, we realize that the free movement of goods in the European Community may bring about certain issues regarding compatibility. The need to find a balance between what local consumers and producers are already familiar with and currently practise and what the market is capable of providing has long been a concern of various Community institutions. As such, the Court of Justice (ECJ) has already come up with principles to be applied within issues of internal market law. While such issues have been the subject of various debates, ‘local’ interest is grounded on consumer protection, particularly on market breadth value and proper product labeling. This chapter examines whether cultural diversity should give more attention to issues regarding the free movement of goods and consumer protection.
