100As regards the alleged presumption of disguised discrimination, the applicant regrets that he is unable to provide further figures in support of his analysis which, he says, is based on common sense, whereas the Commission, by using existing electronic calculation methods, could easily provide a reply on that point. The Commission's statement (p. 12 of its defence) that the sickness insurance deficit is caused not only by officials in active service but also by retired officials confirms that the relevant administrative authority is in a position to provide further information. The applicant therefore considers that, applying the judgment of the Court of Justice in Case 109/88Danfoss [1989] ECR 3199 by analogy, it is for the Commission to rebut that presumption.
