The high European judiciaries from Strasbourg, to Luxembourg, to Paris have become powerful institutional actors whose authority has moved past the interpretive, to the normative, to the political, and to the constitutional levels. At the very moment, however, that the judiciary blossoms into a full-fledged institution of government, it must find some new way to construct its legitimacy. This chapter thus sketches out two case studies that offer different, yet related, attempts to reconstruct judicial legitimacy in contemporary Europe. The first focuses on the judicial appointments reforms concerning the Court of Justice of the European Union and the European Court of Human Rights. The second turns to ongoing debates concerning the use of judicial analytics, the reform of the traditional French mode of composing judicial decisions, and other measures designed to increase access to French judicial reasoning. In a long series of interlocking reforms, both the French and European high courts have managed to further increase their already burgeoning clout.
