This short comment offers two additional arguments, missing from Geir Ulfstein’s account, which may bolster the case for constitutionalisation of the ECtHR. The first is about the ‘pilot judgments’ through which the Court addresses systemic deficits in national legal systems and thus ensures a minimal synchronisation of human rights protection throughout the CoE system. The second manifestation of constitutionalisation of the ECHR system is the increasing role of the ECtHR in the implementation of its own judgments. Ultimately, the legitimacy for the constitutional ambitions of Strasbourg Court should be located primarily in the argumentative resources of the court and in its pursuit of ‘public reason’.
