Judgment_paragraph 53 · United Kingdom of Great Britain and Northern Ireland v European Commission (T-503/12)

53In that regard, according to the case-law, although it is for the Commission to prove that EU rules have been infringed, once it has established such an infringement it is for the Member State to demonstrate, if that be the case, that the Commission made an error as to the financial consequences to be attached to that infringement (see, to that effect, judgments of 24 April 2008 in Belgium v Commission, C‑418/06 P, ECR, EU:C:2008:247, paragraph 135, and in Austria v Commission, cited in paragraph 52 above, EU:T:2009:305, paragraph 181).
