The article promotes a new methodological approach to examining the development of European law that significantly advances our understanding of European legal integration. Building on interdisciplinary debates on European law between historians, lawyers, and political and social scientists, the article argues for analysing European law by approaching a legal text from a bottom-up perspective. Our understanding of legal text includes all texts that jurists consider as legal and use in judicialised conflicts.
Examining how a range of actors have used legal text to shape conflicts instead of taking ‘integration’ (or lack thereof) as the ontological lens yields important new insights into the functioning of European law over time. The case studies in this special issue trialling our methodological approach show that, first, certain areas of European law come into view including non-discrimination, the environment, and human rights. Second, social actors in the Member States and beyond were from the beginning involved in co-creating these areas of law, which indicates that European legal integration has always been more than an elite-driven project. Third, actors have mobilised European law for various reasons, often not tied to ‘Europe’. They have used European law to translate a range of political issues into legal questions. Finally, legal knowledge and expertise – and lawyers – have been central to European integration even if this is not reduced to an understanding of the binary relationship between European institutions and the Member States.
