The book adopts a critical approach and focuses on the application of the fundamental principles of EU law by Cypriot courts, with an emphasis on the public law sector. The approach of the Supreme Court of the Republic of Cyprus regarding the constitutional principles of EU law (principle of supremacy and direct effect) is analyzed in detail with references to relevant national case law and guided by the established jurisprudence of the Court of Justice of the European Union (CJEU).

The same approach is applied to the structural principles of EU law (obligation to interpret and preliminary references). Additionally, the book examines two case studies to assess the impact of the Supreme Court's case law on particularly complex areas of EU law (data retention and free movement of EU citizens' family members).

Overall, the monograph identifies and explains the case law related to the EU from the Supreme Court and proposes specific improvements to the Cypriot approach. Furthermore, the analysis is placed within the broader context of Cypriot public law, and the conclusion highlights a systemic divergence from the traditional approach of the Supreme Court in other areas of public law.

The work is essential for every student of Cypriot public law and EU law and is useful for anyone involved in the study of the coexistence of national and supranational legal orders.
