92In addition, according to settled case-law, the Commission may not limit itself to presuming that the irregularities in question exist but must prove to the requisite legal standard that those irregularities were not limited to the specific cases examined by it. Thus, in order to show that the irregularities are not limited to the specific cases which it examined, it is sufficient for it to adduce evidence which gives rise to a serious and reasonable doubt as to the lawfulness of the entirety of the checks carried out by the Member State concerned. It is not obliged to demonstrate exhaustively that all the checks are inadequate (see, by analogy, Case C-334/01Germany v Commission, paragraph 58).
