Publications by Christophe Hillion
- C. Hillion, The European Union and its East-European Neighbours – A laboratory for the organisation of EU external relations (Oxford, Hart Publishing, 2009)
Often used by the EU as a laboratory for experimenting with new constitutional devices and as a testing ground for innovative institutional practices, the EU Partnerships with the Russian Federation and Ukraine have also foreshadowed change in the system itself. The book seeks to illuminate the general functioning and evolution of the EU system of external relations by examining the development of these Partnerships.
- C. Hillion and P. Koutrakos (eds.), Mixed Agreements Revisited (Oxford, Hart Publishing 2009)
This book provides a comprehensive and up-to-date analysis of the legal and practical problems raised by mixed agreements. In doing so, it brings together the leading international scholars in the area of EU external relations, including two sitting Judges at the European Court of Justice and a Judge at the EFTA Court, along with legal advisors from EU institutions, Member States, and third countries.
- C. Hillion and R. Wessel, ‘The fuzziness of horizontal competence distribution in EU external relations: lessons from the ECOWAS case’, 46 Common Market Law Review (2009)
The paper examines the consequences of the European Court of Justice’s judgment in the ECOWAS case. It notably shed light on the function of the Court jurisdiction under Article 47 TEU, on the demarcation between the European Community development policy and the EU Common Foreign and Security Policy, and examines the impact of the judgment on the quest for coherence in the EU external action.
- C. Hillion, ‘Tous pour un, Un pour tous! Coherence in the External relations of the European Union’, in M. Cremona (ed.), Developments in EU External Relations Law, Collected Courses of the Academy of European Law (Oxford, Oxford University Press 2008), pp. 10-36
The paper sheds light on the notion of coherence in the specific context of EU external relations law, by distinguishing it from the notion of consistency. The paper also examines the contribution of different EU law principles in achieving such coherence (e.g. attribution of powers, principle of supremacy, the duty of cooperation).
- C. Hillion, ‘The EU’s Neighbourhood Policy towards Eastern Europe’, in A. Dashwood and M. Maresceau (eds), Law and Practice of EU External Relations – Salient Features of a Changing Landscape (Cambridge, Cambridge University Press 2008), pp. 309-333
This chapter examines the specific policy that the EU has developed in relation to its Eastern neighbours, notably on the basis of the European Neighbourhood Policy (ENP). Established outside the EU Treaty framework, this policy is all-encompassing in substance and involves integrated institutional arrangements which contribute to its coherence. The paper also identifies fundamental flaws in the ENP, which may undermine its sustainability.
- C. Hillion and R. Wessel, ‘Restraining External Competences of EU Member States under CFSP ’, in M. Cremona and B. De Witte (eds.), EU Foreign Relations Law: Constitutional Fundamentals (Oxford, Hart Publishing 2008), pp. 79-121
This Chapter envisages the impact of the CFSP normative framework on Member States' freedom to conclude international agreements, either inter se or with third parties. Potential restraints that are based on CFSP primary and secondary norms, the nature of the EU competence to conclude international agreements in the field of CFSP, and the effects such EU agreements may have on Member States' foreign policy powers are discussed.
