In several rulings from 1962, 1992, and 2003, the French Constitutional Court (Conseil constitutionnel) has denied jurisdiction over constitutional amendments. This article shows that this solution can only be understood in the light of the doctrinal background that provides its intellectual justification. While refusing to judicially review constitutional amendments, the Constitutional Court is in fact deeply involved in the ongoing process of altering the Constitution. Also, while the quasi-official doctrinal analysis insists on the absence of material limits to the amendment of the Constitution, and on the absence of any “supra-constitutional” rules, an analysis of the language used by the Court in these rulings offers reasons to diverge from this view. While the Court has refused to review constitutional amendments, it has done so in a way that comes very close to the language used by those courts that stated that such amendments were justiciable. Far from adhering to a mere policy of neutrality and self-restraint, the Constitutional Court speaks a “language of eternity” with a rich substantive content.
