152The purpose of Article 26 of the Staff Regulations is to guarantee an official's right to a fair hearing by ensuring that decisions taken by the appointing authority affecting his administrative status and his career are not based on matters concerning his conduct which are not included in his personal file (Perakis v Parliament, cited in paragraph 130 above, paragraph 27; Case T-496/93Allo v Commission [1995] ECR-SC I-A-127 and II-405, paragraph 75; Case T-302/02Kenny v Court of Justice [2003] ECR-SC I-A-235 and II-1137, paragraph 32; and Case T-144/03Schmit v Commission [2005] ECR-SC I-A-101 and II-465, paragraph 133). It applies to promotions, since the abovementioned phrase ‘administrative status’ covers, inter alia, the main career events (Schmit v Commission, paragraph 134).
