  Article 50TEU acknowledges the right of Member States to withdraw from the EU, and contains a specific procedure. It also constitutes the legal basis of an exceptional EU competence whose purpose is to ensure that a Member’s departure is “orderly”. This qualification entails the conclusion of an agreement between the parties on the terms of the withdrawal, but also presupposes that the withdrawal does not undermine the integrity of the EU legal order, while contributing to the fulfilment of the Union’s integration objective. The unprecedented exercise of that competence has enriched the law of European integration: core components of the constitutional identity of the EU have been (re)affirmed, the role of its institutions bolstered, and Union membership law further articulated. Paradoxically, withdrawal may therefore be envisaged as an integration-friendly process.

  Since it concerns Member States of the European Union, the process referred to as ‘Transition 2.0’ is necessarily embedded in EU law. As EU members, transitioning States must restore their constitutional democracies in compliance with the relevant requirements of the Union as common legal order, particularly as they derive from Article 2 TEU. Such a compliance is critical to rebuild trust in the transitioning States’ ability to participate in the EU. The paper discusses the significance of the duty of ‘non-regression’ in structuring the process of transition, and envisages its possible operationalisation in terms of obligations binding the transitioning States, the other Member States and EU institutions, respectively.

  In the European Union (EU), glimmers of democratic renewal have pierced a somber decade of democratic erosion. Since the illiberal Law and Justice (PiS) government in Poland was voted out of office in October 2023, scholars and policymakers have been grappling with how to restore liberal democracy and what role the EU should play. After PiS came to power in 2015, it made systemic and often unconstitutional changes to Poland’s political edifice by undermining judicial independence, coopting the media, and dismantling the rule of law. The pro-democracy Civic Coalition’s electoral victory in October 2023 was therefore celebrated as a rare exemplar of democratic restoration in a context where liberal democracy remains threatened in Europe and around the world. But undoing the damage of years of seeping autocratization and “democratic backsliding” is proving to be much harder than simply winning an election. In a new paper, we illuminate the promises and perils of what we call democratic “frontsliding”—the piecemeal restoration of liberal democratic institutions and practices after a period of democratic backsliding. Unlike other pathways to democratization that build democracy from scratch—sweeping revolutions, for example, that trigger the sudden collapse of an autocratic state—democratic frontsliding proceeds incrementally as a patchworked process that begins (but hardly ends) with electoral change.

  There was a sigh of relief at the European Council meeting, in December 2020.1 After weeks of uncertainty, the Hungarian and Polish governments were persuaded not to veto the adoption of the new EU financial package. The Multiannual Financial Framework (MFF) and the “Next Generation EU” (NGEU) instrument were seemingly saved; the recovery of COVID19- afflicted Europe could finally begin. The way the settlement was reached is, however, less cause for celebration.

  After countless warnings of a democratic recession, there are glimmers of democratic renewal, especially in the European Union. As an illiberal government in Poland was voted out of office, policymakers began debating how to restore liberal democracy and what role the EU should play. We answer by theorizing “democratic frontsliding” –the piecemeal restoration of liberal democratic institutions and practices after a period of democratic erosion– and explain how obstructions to frontsliding can be overcome, leveraging Poland as an exemplary case study. Frontsliding confronts the problem of “autocratic enclaves:” illiberal elites who survive a democratizing election and wield their institutional powers to obstruct democratization. To dismantle autocratic enclaves, we argue that a government may need transgressive acts of defiance and conscientious rule-breaking, which we call “restorative disobedience.” We develop normative criteria for restorative disobedience to prevent its abuse and explain how the EU can mandate, incentivize, and support restorative disobedience.

  For decades, Norway has cooperated with the European Union in matters of foreign policy, security and defence. It has thus participated in EU civilian and military operations, aligned itself with EU political declarations and restrictive measures against states and/or individuals, and collaborated with the European Defence Agency. Unlike other frameworks of cooperation between the EU and Norway, such as the EEA and Schengen agreements, the cooperation in foreign policy, security and defence does not rely on a single setup, with elaborate institutional arrangements and dynamic obligations. Rather, Norway joins forces with the Union in an ad hoc fashion and often based on informal arrangements. This allows for flexibility, but also entails that Norway has few formal channels for exerting influence on EU CFSP decisions to which it subsequently subscribes. Against this backdrop, and as the EU has become more active in this policy area, Norway has shown a renewed interest in deepening its relationship with the Union in CFSP matters. This report examines the ways in which Norway can enhance its cooperation and develop its institutional arrangements with the EU in this fast-evolving field. The discussion is based on an assessment of what the EU is able to offer in view of its constitutional framework, as informed by its on-going discussions with the UK on a future security partnership post-Brexit. Given the increasing interactions between the CFSP and other fields of the EU’s activities, the analysis also discusses whether Norway may draw a cooperation dividend from its participation in the single market through the EEA, to build a deeper and more participatory cooperation with the EU in CFSP matters. The report envisages four possible ways of enhancing the Norway-EU cooperation in the area CFSP: an extension of the present cooperation by ad hoc participation in new CFSP initiatives, a more active use of other existing EU-Norway frameworks of cooperation including the EEA, the setting up of a distinct EU-Norway CFSP agreement and the participation in a multilateralised EU-UK CFSP partnership.

  By leaving the European Union, the United Kingdom withdraws from all EU international commitments. The disentanglement of the UK from the EU, Brexit, will thus affect third states and organisations with which the EU entertains relations. Norway will be no exception, particularly in view of the many agreements the country has concluded with the EU, covering a wide range of areas and entailing a high degree of integration with the Union’s legal order, the EEA being the most important of these agreements.

  Abstract Det følgende omfatter to delrapporter som tjener som underlagsmateriale for sammenfatningene i hovedrapporten TTIP og Norge: Virkninger og handlingsvalg; henholdsvis delrapport I: Norsk deltakelse i handels-partnerskapet mellom EU og USA og delrapport II: Investeringsbeskyttelse og investor-stat tvisteløsning i TTIP – implikasjoner for Norge. Rapportene behandler spørsmålet om eventuell norsk tilknytning til TTIP fra et rettslig perspektiv. Vi peker i den sammenheng på relevante konstitusjonelle problemstillinger norsk deltakelse kan komme i berøring med. Utgangspunktet for vår analyse er at Grunnloven åpner for at Norge påtar seg omfattende folkerettslige forpliktelser. Det viktige er at Stortinget vet hva det gjør og har kontroll med fremtidig utvikling. Derfor er det særlig konkret anvendelse og videreutvikling av traktatforpliktelsene som er interessant å studere nærmere fra et rettslig perspektiv. Slik dynamikk finner sted gjennom regulatorisk samarbeid som leder frem til nye forpliktelser, og ved tvisteløsning – særlig den planlagte investorstat tvisteløsningsmekanismen. Delrapportene er blitt til gjennom samarbeid oss tre imellom. Delrapport I er i hovedsak ført i pennen av Tarjei Bekkedal mens delrapport II i hovedsak er ført i pennen av Ivar Alvik.
