How backsliding government parties defend democratic backsliding in the European Parliament
How do backsliding government parties defend democratic backsliding in the European Parliament? Analyzing manually and large language model-coded data, I find that the backsliders’ arguments do not strongly reflect their illiberalism. Instead, they rely on alleging bias and misconduct by opponents and the advocacy of sovereignty, complemented by situational arguments about election results, Russia, and other member states, among others. Regressio…

International actors and democracy protection: Preventing the spread of illiberal legislation in Eastern Europe and Central Asia
Strengthening mainstream consensus? The effect of radical right populist parties on the defense policies of left parties
We study how the electoral success of radical right populist parties (RRPPs) affects mainstream parties' defense policy positions. The success of RRPPs threatens the credibility of established left-wing parties with coalition and international partners due to substantive overlap between their and RRPPs' defense-skeptical position. We argue that left parties adopt more assertive defense positions to distinguish themselves from RRPPs, thus increasi…
National Differentiation Experience and Citizen Support for Differentiated Integration
This article examines the determinants of public opinion on differentiated integration (DI) in the European Union (EU). Specifically, it tests whether citizen attitudes are informed by the national experience of opt‐outs and exclusions from full participation in EU policies. The study generally finds that support for DI strongly depends on the mode of DI. Even though ‘multi‐speed DI’ is only temporary, it is evaluated more critically than durable…
Does differentiated integration weaken parliamentary involvement? Evidence from the European Union's interparliamentary conferences
Does differentiated integration undermine the motivation of parliamentarians from less integrated member states to become involved in European Union affairs? Focusing on the European Union's new interparliamentary conferences in economic governance, and justice and home affairs, this study examines whether voluntary and involuntary as well as comprehensive and partial differentiation influence parliamentary involvement, measured as participation …
Cascading opt-outs? The effect of the Euro and migration crises on differentiated integration in the European Union
Do integration crises reinforce legal differentiation in European integration? Are differentiated EU policies under stress prone to cascading opt-outs? We argue that integration crises as such are unlikely to cause further fragmentation in already differentiated EU regimes. If the EU decides to adopt new treaties and laws in response to the crises, however, these are likely to reproduce and extend pre-existing patterns of differentiation. Empiric…
The institutional position of national parliaments in the European Union: Developments, Explanations, Effects
This article reviews the literature on the institutional position of national parliaments in the EU. It focuses on new institutional developments, explanations, and effects discussed over the course of the last decade. Existing datasets on parliamentary oversight institutions in EU affairs and economic governance have been extended to 2020 to inform the discussion. A systematic overview of new analyses of the effects of oversight institutions in …
Internet Fragmentation, Political Structuring, and Organizational Concentration in Transnational Engineering Networks
Is the internet at risk of fragmentation? Whereas the literature has examined this question with a focus on domestic policies, communication standards, and internet governance institutions, we analyze fragmentation and alternative outcomes in transnational engineering networks. These networks constitute the social foundations of the unified or ‘global’ internet. Our contributions include: (1) broadening the debate beyond fragmentation‐related net…
The European Semester and Parliamentary Oversight Institutions Inside and Outside of the Euro Area
The European Semester is a challenge for national parliaments but also an opportunity to reform domestic oversight institutions. Drawing on data from all member states, this study examines the conditions under which national parliaments use this opportunity. Is Euro area membership a prerequisite for parliamentary adaptation to the European Semester and, if so, which further combinations of conditions account for variation among Euro area countri…
Citizen-centred or state-centred? The representational design of International Parliamentary Institutions
As a result of the spread of International Parliamentary Institutions (IPIs), international organisations face crucial questions of representational design. We introduce a distinction between citizen-centred and state-centred IPIs in international organisations (IO). Drawing on original data, we show that, even though parliaments might seem likely to foster citizen representation in the international realm, they in fact often follow state-centred…
Ever Looser Union?: Differentiated European Integration
Differentiated integration is a durable feature of the European Union and a major alternative for its future development and reform. This book provides a comprehensive conceptual, theoretical and empirical analysis of differentiation in European integration. It explains differentiation in EU treaties and legislation in general and offers specific accounts of differentiation in the recent enlargements of the EU, the Euro crisis, the Brexit negotia…
Government Euroscepticism and differentiated integration
It is common to consider mass politics and Eurosceptic politicization as 'post-functionalist' constraints that encourage differentiated European integration. This study argues that the relevance of Euroscepticism depends on who wins the domestic competition for government office. European mass politics are organized as delegation systems. These systems concentrate authority in the government and give little influence to parliaments and publics. I…
Grand theories, differentiated integration
Even though differentiation has become a core feature of the EU, the grand theories have focused almost exclusively on uniform integration. In this article, we derive hypotheses about differentiated integration from liberal intergovernmentalism, neofunctionalism, and postfunctionalism. In an analysis of EU treaty making between 1992 and 2016, we find evidence that heterogeneity of both wealth and identity, integration in the area of core state po…
Is parliamentary attention to the EU strongest when it is needed the most? National parliaments and the selective debate of EU policies
When do parliaments debate European Union policies? Normative arguments suggest that debates enhance government accountability. Others warn of government bias, declining debate near elections, and parties avoiding Eurosceptic publics. Our conclusions are more differentiated. We argue that rank-and-file parliamentarians rather than leaders initiate debates. Political incentives guide their debate selection towards salient policies in the countries…
Opting out from European Union legislation: The Differentiation of Secondary Law
Differentiated integration in the European Union (EU) has been primarily discussed and analysed at the treaty level, whereas lack of systematic data has hampered the examination of secondary-law or legislative differentiation. We present a new data set of differentiation in EU legislation from 1958 to 2012, a descriptive analysis and a comparison of the patterns of primary- and secondary-law differentiation across time, member states and policies…
Eastern enlargement and differentiated integration: Towards Normalization
Against the background of theoretical arguments and the historical record, enlargements of the European Union tend to increase differentiated integration. The actual development of differentiation of the 2004 and 2007 accession countries can, therefore, be seen as an indicator of the Union’s integration capacity. We map the newcomers’ differentiated integration since accession, and also distinguish between exemptions and discrimination. Furthermo…
Explaining differentiation in European Union treaties
Since the early 1990s, European integration has become increasingly differentiated. Analysing the conditions under which member states make use of the opportunity to opt out of, or exclude other countries from, European integration, we argue that different explanations apply to treaty and accession negotiations, respectively. Threatening to block deeper integration, member states with strong national identities secure differentiations in treaty r…

From capacity to sovereignty: Legislative politics and differentiated integration in the European Union
The literature suggests that legislative politics among European Union Member States is characterised by economic exchanges, and constrained by the social norms of a European community of legislators. Both views draw a clear line between the legislative process and the conflicts over sovereignty that have left their mark on treaty making and European public opinion since the 1990s. This article suggests revisiting this view, based on an analysis …
Party groups and committee negotiations in the European Parliament: Outside Attention and the Anticipation of Plenary Conflict
We study the relationship of the European Parliament's (EP) standing committees and party groups. According to recent studies, committees are the centre of EP policy-making, while party groups enable the transmission of policy positions from specialists to generalists through the mechanism of 'perceived preference coherence' (Ringe 2010 Ringe, N. (2010) Who Decides, and How? Preferences, Uncertainty, and Policy Choice in the European Parliament, …
Parliamentary co-evolution: National parliamentary reactions to the empowerment of the European Parliament
Existing research on the European Union's (EU) multilevel parliamentary system builds on the hypothesis of parallel evolution, situating explanations for European Parliament (EP) empowerment at the EU level and explanations for national parliamentary powers in EU affairs at the national level. We propose the hypothesis of co-evolution, which specifies a connection between national and European arenas of parliamentarization. We study whether the E…
Bureaucracy and Democracy: Intra-Parliamentary Delegation in European Union Affairs
Recent literature notes that national parliaments’ growing relevance in European Union (EU) affairs might have led to the empowerment of legislative bureaucrats rather than elected politicians, an argument that we may label the “bureaucratisation thesis”. This paper suggests that a delegation approach is most suitable for studying the democratic relevance of legislative bureaucracy in EU affairs. From a delegation perspective, however, parliament…
Instrumental and Constitutional Differentiation in the E uropean U nion
Differentiation has become a salient feature of E uropean integration. Yet systematic empirical evidence is lacking about its origins, duration and variation across countries and policies. This article provides such evidence from a new data set on differentiation in E uropean U nion treaty law. In addition, it is argued that two logics of treaty‐based differentiation are at work. ‘Instrumental differentiation’ originates in enlargement and is mot…
National Parliamentary Control of European Union Affairs: A Cross-national and Longitudinal Comparison
Recent research on national parliamentary control of European Union affairs relies primarily on cross-sectional, contemporary data, whereas information on the nature and frequency of changes within countries and over time is currently lacking. This lack of data not only limits our substantive knowledge of the role of national parliaments in EU affairs but also constrains studies of the causes of parliamentary control. This research note offers a …

European integration and national parliamentary oversight institutions
This article analyses to what extent and why national parliaments have created oversight institutions to adapt to European integration. Employing data from 22 member states from 1984–2006, the analysis suggests that government-supporting parliamentary groups create oversight institutions to enhance policy participation as integration becomes more important. Moreover, parliamentarians improve their access to information about government policy if …

Technical or Political? An Exploration of the Work of Officials in the Committees of the European Parliament
In conjunction with the gradual empowerment of the European Parliament, interest in its internal politics and in particular its committee system has increased considerably. While much has been learned about the influence of parliamentarians, little is known of the role of their unelected supporters. Although the literature indicates that officials are involved in the policy process, it remains open to question whether their work is fundamentally …

Legislative negotiations in the European Parliament
In order to capitalize on its increasing legislative powers, the European Parliament (EP) has had to specialize internally. The scholarly literature has predominantly studied the structural manifestations of specialization, such as the allocation of committee seats among parliamentarians. This article sheds light on a second selection process: participation in legislative negotiations. For every given legislative dossier, parliamentarians have to…
