In the name of COVID: An Assessment of the Schengen Internal Border Controls and Travel Restrictions in the EU
(Policy Department for Citizen's Rights and Constitutional Affairs, European Parliament, 2020) Carrera, Sergio; Luk, Ngo Chun; Lazaruk, Monka, Laura
This study, commissioned by the European Parliament’s Policy Department for Citizens’ Rights and Constitutional Affairs at the request of the LIBE Committee, assesses the mobility restrictive measures adopted by the EU and its Member States in the fight against COVID-19. It examines the reintroduction of Schengen internal border controls and intra- and extra-EU travel restrictions. It assesses their compatibility with the Schengen Borders Code, including proportionality, non-discrimination, privacy and free movement. The research demonstrates that policy priorities have moved from a logic of containment to one characterized by a policing approach on intra-EU mobility giving priority to the use of police identity/health checks, interoperable databases and the electronic surveillance of every traveller. It concludes that Schengen is not in 'crisis'. Instead there has been an ‘EU enforcement and evaluation gap’ of Member States compliance with EU rules in areas falling under EU competence.

The international diffusion of expatriate dual citizenship
(Oxford Academic, 2019) Vink, Maarten; Schakel, Arhan H.; Reichel, David; Luk, Ngo Chun; de Groot, René
While the global increase of expatriate dual citizenship acceptance over the past decades has been widely observed, the temporal and spatial contexts of this trend have remained understudied. Based on a novel data set of expatriate dual citizenship policies worldwide since 1960, we find that dual citizenship toleration has increased in the last half century from one-third to three-quarter of states globally. We argue that these domestic policy changes should be understood in light of normative pressure in a world where restrictions on individual choice in citizenship status are increasingly contested and where liberalisation is reinforced through interdependence and diaspora politics. We apply Cox proportional hazard models to examine dual citizenship liberalisation and find that states are more likely to move to a tolerant policy if neighbouring states have done so and that they tend to do so in conjunction with extending voting rights to citizens residing abroad and receiving remittances from abroad. Contrary to other studies, we do not observe significant variation by regime type.
Love thy neighbour? Coronavirus politics and their impact on EU freedoms and rule of law in the Schengen Area.
(Center for European Policy Studies (CEPS), 2020) Carrera, Sergio; Luk, Ngo Chun
This Paper examines the legality of restrictions on intra-EU and international traffic of persons introduced in the name of COVID-19. It provides a typology of measures including the reintroduction of internal border controls, restrictions of specific international traffic modes and intra-EU and international travel bans. Many of these have been adopted in combination with declarations of a ‘state of emergency’, which affect to different degrees national checks and balances over executive action. These measures pose fundamental questions as to the raison d’être of the European Union, and the foundations of the Single Market, the Schengen system and European citizenship. The analysis shows a complex web of parallel and incoherent national regimes restricting unilaterally the entry/exit of people, and displaying wide divergences in the conditions for people to be allowed to move in the Schengen area for legitimate reasons. And while the Schengen rules envisage the possibility to reintroduce internal border checks, Schengen Ministries of the Interior do not have carte blanche. They need to justify that these policies are based on scientific analysis backing up not only their suitability and necessity, but also that they don’t disproportionately impact on essential fundamental rights and rule of law guarantees, including those that are non-derogable even in times of declared crises. Our assessment shows that this has not been the case. Many of the cross-border mobility restrictions unlawfully interfere with EU freedoms as well as undercutting the checks and balances envisaged in EU and national law. The Paper concludes by recommending the EU adopt an “EU-wide Schengen Stress Test”, which would provide a periodic country-by-country ‘quali-quantitative’ assessment of the state of free movement, Schengen rules and asylum legislation across the Union.
European Union Policies on Onward and Secondary Movements of Asylum-seekers and Refugees: A Critical Overview of the EU’s Migration Management Complex
(Center for European Policy Studies (CEPS), 2022) Carrera, Sergio; Luk, Ngo Chun; Mager, Friederike; Stefan, Marco
This report examines European Union policies designed to manage the irregular movements of asylum-seekers and refugees from selected African and Asian countries, and what the EU calls ‘secondary movements’ inside the Schengen Area. It provides a detailed qualitative assessment of the EU’s migration management complex i.e. the conglomerate of EU instruments and actors behind policies aimed at managing the unauthorised cross-border mobility by asylum seekers and refugees. The report analyses the conceptual and methodological biases behind the ‘pull and push migration theory’ and the predominant use of ‘migration maps’ representing arrows symbolising unauthorised human journeys following seemingly linear ‘migration routes’ and heading towards the EU. It proposes that these conceptual and visual tools should no longer be used, and instead the focus should be on the roles and impacts of the EU migration management complex in co-creating and reproducing the very phenomena that they are seeking to address, i.e. irregular human mobility across various world regions and within Europe. The assessment provides a cross-instrument and cross-actor examination characterising the policies that the EU currently implements in the scope of both its external and internal dimensions. The analysis comes with a set of visualisations and infographics illustrating EU instruments, and their prevailing priorities. The report finds that EU policies co-create irregularity and the unauthorised mobility of asylum seekers coming from certain non-European world regions. EU policies disregard individuals’ legitimate reasons for engaging (or not) in cross-border mobility and their agency to self-relocate in the Schengen Area. They create discrimination against nationals of certain African and Asian countries from accessing genuine and effective legal entry mechanisms and the ability to seek asylum in the Union. The report recommends the need to ensure a systematic use of ex ante, ongoing and ex post human rights impact assessments and the establishment of an independent, transparent and effective monitoring mechanism, in the form of an EU observatory, to monitor the hyper complexity emerging from EU external and internal migration policies, so as to ensure their accountability and consistency with EU rule of law and fundamental rights principles
