Constitutional Disintegration and Disruption

The United Kingdom's unprecedented withdrawal from the European Union in 2020 may be regarded as the first example of European 'disintegration'. This moment, however, was preceded by decades of 'disruption' as the UK, Ireland, and Denmark pursued opt-outs from the supranational constitutional order. Constitutional Disintegration and Disruption: Withdrawal and Opt-Outs from the European Union provides the first comprehensive analysis of these two phenomena. The book presents the European Union as an order that is legitimated by individuals playing a dual role as both nationals of Member States and citizens of the European Union; in turn, individuals are both democratic subjects and juridical objects within this order. The EU Treaties have instituted a 'triptych' for the exercise of 'constituted constituent power' by these individuals: Article 49 TEU allowing accession, Article 48 TEU enabling amendment, and Article 50 TEU as a mechanism for the repatriation of power through withdrawal. Opt-outs are an iterative anomaly that have arisen through the retention of amendment power by representatives of Member State nationals. Reservations of constituent power have been operationalized in Protocols to the Treaties. By contrast, the withdrawal clause was proactively inserted into the Treaties as a sovereign right for Member State nationals subject to an orderly supranational procedure for the benefit of all EU citizens. The book presents narratives of disruption and disintegration that provide comprehensive historical overviews of how opt-outs and withdrawal arose and developed. Constitutional Disintegration and Disruption concludes with criticism of the consequences of these phenomena for individuals, and proposes reforms to the EU Treaties that would enable citizens to more fully realize their dual role in the European constitutional space.
