As the European Union (EU) was slowly re-emerging from the COVID-19 pandemic, it faced another unprecedented shock: Russia's large-scale military invasion of Ukraine. In responding to Russia's invasion, however, the EU was able to build on the legal and policy measures that it had developed to address the COVID-19 pandemic. In particular, NextGenerationEU (NGEU) and the use of common debt provided a template that the EU could use to mobilize financial resources to support Ukraine against Russia's aggression.

The article examines the legal structure and constitutional consequences of ‘Next Generation EU’ (NGEU)—the innovative recovery fund that the European Union (EU) established to address the socio-economic consequences of the COVID-19 pandemic. The article sheds light on the complex normative constellation that was used to erect NGEU, and explains how this was satisfactorily done within the existing Treaty framework, by resorting to current legal bases. At the same time, however, the article underlines the profound constitutional consequences that NGEU has on the EU's architecture of economic governance. To this end, the article contrasts the strategy chosen to respond to the COVID-19 pandemic to that embraced to tackle the euro-crisis a decade ago, and concludes emphasising how NGEU significantly contributes to the federalisation of the EU, endowing its fiscal union with a fiscal capacity analogous to that of other federal regimes.

This article explores the challenges of the extraterritorial application of the right to be forgotten and, more broadly, of EU data protection law in light of the recent case law of the ECJ. The paper explains that there are good arguments for the EU to apply its high data protection standards outside its borders, but that such an extraterritorial application faces challenges, as it may clash with duties of international comity, legal diversity, or contrasting rulings delivered by courts in other jurisdictions. As the article points out from a comparative perspective, the protection of privacy in the digital age increasingly exposes a tension between efforts by legal systems to impose their high standards of data protection outside their borders – a dynamic which could be regarded as ‘imperialist’ – and claims by other legal systems to assert their own power over data – a dynamic which one could name ‘sovereigntist’. As the article suggests, navigating between the Scylla of imperialism and the Charybdis of sovereigntism will not be an easy task. In this context, greater convergence in the data protection framework of liberal democratic systems worldwide appears as the preferable path to secure privacy in the digital age.

This article analyzes the recent judgment of the European Court of Justice (ECJ) in Gauweiler, answering the first preliminary reference ever by the German Constitutional Court (BVerfG), on the legality of the Outright Monetary Transaction (OMT) program of the European Central Bank (ECB). As the article explains, the ECJ rejected any possible claim of illegality of a key program devised by the ECB at the height of the Euro-crisis. However, because the BVerfG had defined the OMT program as ultra vires, and had threatened to strike it down if the ECJ did not reach the same result, the article defends the principle of the supremacy of European Union (EU) law, indicating that a possible nullification of the OMT program by the BVerfG would be clearly unlawful. To re-affirm the supremacy of EU law, the article argues that this principle is functional to ensure the equality of the member states before the law, preventing each country of the EU from cherry-picking which provisions of EU it likes or not. As the article suggests, respect of the principle of the supremacy of EU law – including by the BVerfG – is ultimately in the interest of every EU member state, including of Germany.

On 23 July 2008, the President of the French Republic promulgated – two days after the final vote of the two chambers of Parliament sitting jointly in Congrès (Congress) – the constitutional revision bill “de modernisation des institutions de la Vème République” (of modernization of the institutions of the Fifth Republic) n° 2008–724. The bill was mainly based on the research work done by a comité des sages (expert committee) “de réflexion et de proposition sur la modernisation et le rééquilibrage des institutions de la Vème République” (for the reflection and the proposition on the modernization and rebalancing of the institutions of the Fifth Republic). It had been presented by the Government to Parliament on 23 April 2008 and twice voted for by the Assemblée Nationale (National Assembly) and the Sénat (Senate).

This article examines how the Euro-crisis and responses to it have affected the horizontal relations of power between the EU Member States. It is argued that, whereas the EU institutional system had been designed since its foundation to strike a balance between state equality and state power, the Euro-crisis and the responses to it have increasingly upset this balance. A dynamic of inter-state domination is evidenced by the intergovernmental modes of governance within the European Council, as well as by the legal reforms in salient areas such as economic assistance, financial stabilisation and banking resolution, which have entrenched asymmetries between the states. In this article, it is argued that this dynamic constitutes a worrying development, given the anti-hegemonic nature of the EU integration project, and shows how intergovernmentalism paradoxically caters for powerful Member States. The article ends by considering options for institutional reforms, cautioning against the proposal to parliamentarise the EU and emphasising the potential of a new separation-of-powers system to restore a proper balance between the Member States.
