The book adopts a critical yardstick and focuses on the implementation of fundamental principles of EU law by the Cyprus courts and places the emphasis on the field of public law. The approach of the Supreme Court of the Republic of Cyprus as to the constitutional principles of EU law (principle of the supremacy and direct effect) is thoroughly analyzed with reference to the relevant national case law and has as compass the established case law of the CJEU. The same approach is applied in relation to the structural principles of EU law (duty of interpretation and preliminary references). Moreover, the book examines two case studies in order to evaluate the impact of the case law of the Supreme Court in specifically complex areas of EU law (data retention and the free movement of members of EU citizens` family). Overall, the monograph identifies and explains the EU related jurisprudence of the Supreme Court and makes specific suggestions for improving the Cypriot approach. Furthermore, the analysis is placed in the broader context of Cypriot public law and the conclusion reached identifies systemic deviation 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 engaging in the study of the coexistence of national and supranational legal orders.
