48In that regard, it must be recalled that, where the Court rules, in proceedings under Article 267 EC, that an act of the European Union is invalid, its decision has the legal effect of requiring the institutions concerned to take the necessary measures to remedy that illegality, as the obligation laid down in Article 266 TFEU in the case of a judgment annulling a measure applies in such a situation by analogy to judgments of the Court declaring an act of the European Union to be invalid (see, to that effect, judgment in Régie Networks, C‑333/07, EU:C:2008:764, paragraph 124 and the case-law cited).
