Judgment_paragraph 55 · SP SpA and Others v Commission of the European Communities (T-27/03, T-46/03, T-58/03, T-79/03, T-80/03, T-97/03, T-98/03)

55The Commission points out that the EC Treaty and the ECSC Treaty form part of one and the same legal system, that is to say the Community legal order (Opinion 1/91 [1991] ECR I-6079, paragraph 21). It explains that, given the unique character of that legal order, the Community judicature has interpreted the provisions of the ECSC and EAEC Treaties with reference to the provisions of the EC Treaty on the basis of common principles to which all the Community treaties adhere (Case C-221/88 Busseni [1990] ECR I-495, paragraphs 16 and 21). Article 65 CS has therefore been interpreted consistently with Article 81 EC (Case 13/60 Geitling Ruhrkohlen-Verkaufsgesellschaft and Others v High Authority [1962] ECR 83; Case T-141/94 Thyssen Stahl v Commission [1999] ECR II-347, paragraphs 262, 266 and 277).
