This research investigates the use of comparative law within the Council of the EU, particularly in the field of labour law, with the aim of filling gaps in the literature and improving the understanding of EU legislative processes. The study examines the theoretical and practical frameworks of comparative legal analysis, focusing on its application within the Council Legal Service (CLS). Using a multidimensional methodology encompassing both doctrinal and empirical approaches, the research integrates a critical literature review, participant observation and interviews. Through a comprehensive synthesis of academic studies and practical insights, the study sheds light on the Council’s interpretive methods, decision-making processes, and the role of comparative law within it. It delves into the CLS’s methods of normative analysis, highlighting the importance of comparative legal analysis in resolving legal antinomies, particularly in labour law. By bridging the gap between academic discourse and institutional practice, this research contributes to an understanding of comparative law analysis methods within EU legislative bodies, fostering the transparency, effectiveness, and coherence of legal decision-making processes.
