It is likely that the European Court of Justice’s (ECJ) objection in Opinion 2/13 regarding the absence of judicial remedies in certain Common Foreign and Security Policy (CFSP) areas can hardly be accommodated in a future revised Accession Project to the European Convention on Human Rights (ECHR). This is basically due to obstacles to proceeding with reform of the EU Treaties or establishing an ECHR reservation clause. However, as a matter of fact, the exact dimension of this problem seems to be quite relative. First of all, this is because recent ECJ case-law is gradually eroding the Court’s lack of competence, in particular, after Rosneft. Next, this is because, in those cases where there is still an absence of effective judicial protection, national courts – as EU ordinary courts – could fill this gap. Finally, this gap could also be filled by creating accountability mechanisms in the area of human rights within the framework of Common Security and Defence Policy (CSDP) missions.
