Methodological issues pervade contemporary debates in EU law. EU lawyers largely agree on the need to go beyond the classical opposition between the two perspectives that have long dominated the field of European studies: on the one hand, the purely doctrinal approach, which limits itself to seeking answers to particular legal problems or to systematizing the state of the law, and on the other hand, the purely strategic perspective, which reduces law to external determinants. Lawyers are increasingly aware of the limits of a purely doctrinal model and debate how to improve it or how to replace it with new approaches. At the same time, scholars from other disciplines are increasingly taking the technical dimensions of EU law as their object and are more and more read by lawyers themselves. This raises the question of the singularity of a legal approach to EU law. If there is controversy about methods, it is because there is agreement on the need to debate but also awareness of what is at stake: a reconfiguration of European studies.
