National parliaments and European integration

The role of national legislatures in European integration first received serious attention in the mid-1990s in connection with debates on the EU’s democratic deficit. After that, both academics and politicians have entered a lively debate on how to best involve national parliaments in EU affairs. The purpose of this paper is to critically examine the state of the research on the role of national parliaments in European integration and to suggest avenues for further research. The main argument is that through focusing almost exclusively on scrutiny of European affairs, the literature has failed to acknowledge the multiple constraints that impact on legislatures. There is a demand for more theory-driven analyses of actual behaviour that extend beyond describing formal procedures and organizational choices. Future research should also pay more attention to the strategies of political parties and to the incentives of individual MPs to become involved in European affairs.
