49The applicant refers in that regard to a judgment of the Court of Justice holding that an action challenging a communication from the administration which is merely an act preparatory to a subsequent decision by the appointing authority is admissible where its content and the nature of its source are such that it may be objectively considered as constituting a final decision taken by the appropriate administrative authority (Joined Cases 161/80 and 162/80 Carbognani and Another v Commission [1981] ECR 543). He also refers to a judgment of the Court of First Instance holding that an official may bring an action against a list of officials found to be most deserving of promotion when his name does not appear on that list because, even if that list is not the final one, there is no real chance for the official in question of being promoted (Case T-82/89Marcato v Commission [1990] ECR II-735, paragraph 52). He concludes that an action brought against an act which is only preparatory is admissible if it appears clearly from that act that a negative decision has been taken against an official and that that decision cannot be amended.
