20That principle is also applicable, subject to certain conditions, where the breach at issue stems from a decision of a court adjudicating at last instance. In the light of the essential role played by the judiciary in the protection of the rights derived by individuals from rules of EU law and of the fact that a court ruling at last instance constitutes, by definition, the last instance before which those individuals can enforce the rights conferred on them by those rules, the Court considers that the full effectiveness of those rules would be called in question and the protection of those rights would be weakened if individuals were precluded from being able, under certain conditions, to obtain reparation when their rights are affected by a breach of EU law attributable to a decision of a court of a Member State adjudicating at last instance (see, to that effect, judgments of 30 September 2003 in Köbler, C‑224/01, EU:C:2003:513, paragraphs 32 to 36 and 59; of 13 June 2006 in Traghetti del Mediterraneo, C‑173/03, EU:C:2006:391, paragraph 31, and of 9 September 2015 in Ferreira da Silva e Brito and Others, C‑160/14, EU:C:2015:565, paragraph 47).
