Along with the progressive insertion of the right to an effective remedy in instruments of secondary legislation in different sub-areas of EU migration and asylum law, the question of interplay between the right to an effective remedy guaranteed at the level of primary law (Article 47 of the EU Charter of Fundamental Rights) and secondary law has been gaining more and more importance for the determination of boundaries between matters covered by EU law and those governed by national legislation. The present contribution will seek to examine the interactions between Article 47 of the Charter and the relevant provisions of secondary law in the field of migration and asylum. It will demonstrate that despite dense codification of the right to an effective remedy in different instruments of secondary law, Article 47 of the Charter continues to play a significant role in the case law of the Court of Justice of the EU concerning procedural guarantees conferred upon migrants and asylum seekers. A particular emphasis will be put on the analysis of recent case law developments that reveal the potential of Article 47 of the Charter to serve as a main tool for readjustment of national procedural rules.
