Politics of expertise in the European Parliament: discursive constructions and contestations of expertise by party-political actors

This article analyses the politics of expertise in the European Parliament (EP). We aim to understand how MEPs and political group staff discursively construct expertise, its role in parliamentary work, and how expertise is politicized in the EP. The qualitative analysis is based on an extensive interview dataset (n = 133) from the 8th and 9th legislative terms. It builds on a constructivist approach that sees expertise as constructed, legitimized, and institutionalized in discourses and practices and shaped by struggles and power relations. The article shows that expertise in the EP is a political rather than a technical question. Understandings of expertise and its role are constituted and contested, and political ideologies shape understandings of expertise. Although the role of technical policy expertise in the EP is broadly accepted, it is approached through a political lens, and political groups value and use expertise in different ways in internal policymaking.
