The Court has consistently held that the right of individuals to rely on the directly effective provisions of the Treaty before national courts is only a minimum guarantee and is not sufficient in itself to ensure the full and complete implementation of the Treaty (see, in particular, Case 168/85 Commission v Italy [1986] ECR 2945, paragraph 11, Case C120/88 Commission v Italy [1991] ECR I-621, paragraph 10, and C-119/89 Commission v Spain [1991] ECR I-641, paragraph 9).
