Prospective overruling

The paper analyzes the recent jurisprudence about prospective overruling on national administrative measures governed by EU law (Council of State judgment nos 17 e 18/2021) to test its compliance with ECJ’s jurisprudence. Indeed, it’s in the Court of Justice’s exclusive jurisdiction to determine if a declared violation of UE law may be tolerated for the time necessary to avoid the infringement of a legitimate expectation. So sentences of national judge about prospective overruling concerning EU law are ultra vires.
