287However, even without determining the validity of that explanation by reference to the documents relied on by the Commission, it must be pointed out that it is settled case-law that the reasons for a decision must appear in the actual body of the decision and that, save in exceptional circumstances, explanations given ex post facto cannot be taken into account (Case T-61/89Dansk Pelsdyravlerforening v Commission [1992] ECR II-1931, paragraph 131; Case T-295/94Buchmann v Commission [1998] ECR II-813, paragraph 171; and Joined Cases T-374/94, T-375/94, T-384/94 and T-388/94European Night Services and Others v Commission [1998] ECR II-3141, paragraph 95). It follows that the decision must be self-sufficient and that the reasons on which it is based may not be stated in written or oral explanations given subsequently when the decision in question is already the subject of proceedings brought before the Community judicature (Case T-16/91 RV Rendo and Others v Commission [1996] ECR II-1827, paragraph 45).
