46In reliance upon the case-law of the Court of Justice and the Court of First Instance, the applicant considers that a trader to whom Community rules apply may challenge the validity of those rules where they fail to take account of his specific situation and where their effect is to deprive him of a right and to cause him damage, especially where the legal position of the trader in question is adversely affected by circumstances which differentiate him from all other persons and distinguish him individually in the same way as the person to whom the measure is addressed (Case 25/62Plaumann v Commission [1963] ECR 95, and Codorniu, cited above, paragraph 20; Case T-476/93FRSEA and FNSEA v Council [1993] ECR II-1187, paragraph 20, and Case T-489/93Unifruit Hellas v Commission [1994] ECR II-1201, paragraph 21). The applicant considers itself to form part of ‘a closed class the members of which are identifiable’, namely traders, whose specific rights are affected (Case 231/82Spijker v Commission [1983] ECR 2559, paragraph 8, Case C-152/88Sofrimport v Commission [1990] ECR I-2477, paragraph 10, and Case C-358/89Extramet Industrie v Council [1991] ECR I-2501, paragraph 17; Case T-99/94Asocarne v Council [1994] ECR II-871, paragraphs 20 and 21; Unifruit, cited above, paragraph 23).
