Reviewing some of the judgments handed down recently, this judgment came up as making clear what a member State should do if a judgment of the Court of Justice handed down in a preliminary ruling procedure declares that national legislation is incompatible with EC law.
Most of the judgment in Joined Cases C-231/06 to C-233/06 Office national des pensions v. Emilienne Jonkman concerns sex discrimination and statutory pension funds. That is a fairly well-trodden path and we don't propose to go down it here.
What we'll concentrate on now is the obligation of a member State as a consequence of a preliminary ruling.
It is obvious that the referring court must apply the ruling of the Court of Justice to the case of which it is seised. But what of the obligations of the member State more generally if its legislation is held incompatible with EC law ? The judgment does give a timely reminder that a member State must adapt its legislation following a judgment given by the Court on an order for reference from which it is apparent that national legislation is incompatible with EC law.
The Court recalls first that under the principle of cooperation in good faith laid down in Article 10 EC, member States are required to nullify the unlawful consequences of a breach of EC law (Case C-201/02 Wells, at paragraph 64).
The Court makes clear that following a judgment given by the Court on an order for reference from which it is apparent that national legislation is incompatible with EC law, it is for the authorities of the member State concerned to take the general or particular measures necessary to ensure that Community law is complied within that state (see, to that effect, Wells again, paragraphs 64 and 65, and Case C-495/00 Azienda Agricola Giorgio, Giovanni e Luciano Visentin and Others, at paragraph 39). While member States are free to choose the measures to be taken, they must in particular ensure that national law is changed so as to comply with EC law as soon as possible and that the rights which individuals derive from EC law are given full effect.
Finally the Court held that in situations of discrimination contrary to EC law, for as long as measures reinstating equal treatment have not been adopted, observance of the principle of equality can be ensured only by granting to persons within the disadvantaged category the same advantages as those enjoyed by persons within the favored category. In such a situation, a national court must set aside any discriminatory provision of national law, without having to request or await its prior removal by the legislature, and apply to members of the disadvantaged group the same arrangements as those enjoyed by the persons in the other category (Case C‑408/92 Avdel Systems, at paragraphs 16 and 17; Case C‑442/00 Rodríguez Caballero, paragraphs 42 and 43, and Case C‑81/05 Cordero Alonso, at paragraphs 45 and 46).
