67Thus, the Court has already held that, while certain objective and subjective factors connected with the concept of fault under a national legal system may be relevant, in the light of the case-law referred to in paragraph 51 of the present judgment, for the purpose of determining whether or not a given breach of EU law is sufficiently serious, the fact remains that the obligation to make reparation for loss or damage caused to individuals cannot depend upon a condition based on any concept of fault going beyond that of a sufficiently serious breach of EU law. Imposition of such a supplementary condition would be tantamount to calling in question the right to reparation founded on the EU legal order (see Brasserie du Pêcheur and Factortame, paragraphs 78 to 80, and Haim, paragraph 39).
