THE NUANCED CONSTITUTION: AN ESSAY ON COMMON LAW CONSTITUTIONAL RIGHTS Candidate: Eva Christina Lienen Institution: UCL Degree: PhD 1 DECLARATION OF AUTHENTICITY ‘I, Eva Christina Lienen, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis.' Signed: Dated: 2 ABSTRACT This thesis argues that the examination of judicial reasoning in public law cases shows that the UK constitution is best described as ‘nuanced’, rather than by reference to either political or common law constitutionalism. One manifestation of the nuanced constitution is the concept of common law constitutional rights, i.e. human rights under the English common law, which have recently been revived by the UK Supreme Court in cases such as UNISON v Lord Chancellor. I examine these rights with a view to portraying the inner workings of the nuanced constitution as well as its shortcomings. Drawing on the historical development and the contemporary characteristics of common law constitutional rights, I contend that the latter have been negatively impacted by the ambiguities underlying the wider constitutional framework. As the Privacy International litigation shows, the senior Judiciary is in significant disagreement about some of the core aspects of the UK constitution. Indeed, we cannot detect a principled constitutional philosophy guiding decision-making; the nuanced constitution is torn between the irreconcilable tenets of political and legal constitutionalism. Due to this tension the range and scope of common law constitutional rights remains unclear, and their legitimacy contested. Furthermore, given the continued role of Parliamentary Sovereignty, common law constitutional rights are at constant risk of being abrogated by clear statutory language. Having found that the nuanced constitution - despite the resurgence and increased weight of common law constitutional rights - is unable to adequately protect essential constitutional values, I advance an alternative approach to constitutional rights protection. Abandoning Parliamentary Sovereignty, which is riddled with conceptual and normative shortcomings, I propose a more principled framework that effectively protects those rights that are constitutive of a liberal democracy, properly understood. 3 IMPACT STATEMENT This thesis calls for a more explicitly theoretically grounded analysis of UK public law. It highlights the current low levels of engagement with substantive constitutional values both in the academic literature and in judicial reasoning. Greater coherence in common law constitutional rights jurisprudence could be achieved if scholars and judges were to adopt a less institutional legitimacy-centric approach, focusing instead on the core values of a liberal democracy. In the course of writing this thesis I have sought to contribute to the debate on judicial reasoning in public law adjudication by publishing some of my work in two highly regarded law journals (‘Common law constitutional rights jurisprudence: public law at a crossroads?’ [2018] Public Law 649 and ‘Judicial Constitutional Comparativism at the UK Supreme Court’ (2019) 39(1) Legal Studies 166). Additionally, I have highlighted the significance of this line of jurisprudence by regularly contributing to widely read law blogs, such as the UK Constitutional Law Association Blog (2017), the UCL Constitution Unit Blog (2017) and the IACL- AIDC Blog (2019). I also spoke at numerous conferences about the opportunity the current resurgence of common law constitutional rights jurisprudence offers to re-examine our constitutional arrangements more broadly. In particular, I highlighted the significance of the UK Supreme Court judgment in UNISON at the Public Law Conference co-organised by the University of Cambridge and the University of Melbourne (2018). I was able to further contribute to comparative legal analysis by presenting my research to an audience of academics and practitioners from Canada and other common law jurisdictions at the Unwritten Constitutional Norms and Principles: Contemporary Perspectives Symposium hosted by the University of Ottawa (2019). 4 Going forward, this thesis’ critique of the current lack of a principled approach towards autochthonous case law based human rights protection is likely to influence future legal debate and scholarship. While this research is likely to have the clearest impact within academia, there is a strong potential for it to also benefit judges and politicians. To that end, apart from my ambition to convert this thesis into a monograph, I will explore other disseminating outputs to make my findings and proposals available to a wider audience. For instance, the political ambition to abolish the Human Rights Act 1998 has been unhelpfully bolstered by the mistaken assumption that the English common law offers the same or a highly similar level of human rights protection. This thesis challenges that assumption, and its findings could potentially benefit NGOs that raise awareness about the importance and indispensability of the Act. 5 TABLE OF CONTENTS ACKNOWLEDGEMENTS p. 11 INTRODUCTION p. 13 1.
