AbstractThis paper examines the impact of European Court of Human Rights (ECtHR) decisions on the field of religion and education in Greece around the issues of the content and objectives of religious education, the exemption thereof, and religious symbols in school. The findings indicate that despite the relevance of ECtHR case law with the specific field in Greece, the Court's role in influencing such national debates is minimal. Drawing on empirical research and discourse analysis, the paper argues that this is due to the doctrine of the margin of appreciation, apparently linked to strategic references to and varying interpretations of the Court's judgments; the unwillingness of actors to litigate in a potentially sensitive, lengthy, and costly procedure; and to a shared belief in the perceived primacy of constitutional provisions on religion and education that precludes the formation of structured mobilizations.
