9In support of its plea of inadmissibility, the Commission explains that the applicants are neither an undertaking nor an association within the meaning of the ECSC Treaty. It recalls that, in its case-law concerning the admissibility of actions for annulment of ECSC decisions, the Court of Justice has confined itself to applying the clear provisions of Article 33 of the Treaty and has expressly refrained from extending the right to bring proceedings to other categories of person. Moreover, it points out that the EC Treaty clearly cannot apply to proceedings brought against a decision which is based exclusively on the ECSC Treaty.
10The Commission adds, furthermore, that the application for suspension of the operation of the decision is inadmissible on the ground that it was not submitted in a separate document.
11The applicants have not submitted any observations on the plea of inadmissibility. In their application, they explained that they were acting not only in their capacity as trade-union committee chairmen but also as employees of Forges de Clabecq. They claim that the contested decision obliged the directors to announce the undertaking's insolvency and that it consequently caused the loss of their jobs. The applicants conclude that in their capacity as workers and defenders of workers' rights, they are differentiated from all other persons and that the contested decision is therefore of individual concern to them.
12The applicants consider that the decision is also of direct concern to them because it leaves no margin of discretion to the Belgian authorities. They suffer the effects of the decision without it being open to the State to guarantee their right to work under the Belgian Constitution.
13According to the applicants, in its decision the Commission applied or should have applied not only the ECSC Treaty, but also the EC Treaty. In that respect, they acknowledge that they are not entitled to seek the annulment of the contested decision under the ECSC Treaty and claim that the Commission should therefore have also applied other provisions, which would have enabled them to bring the present proceedings. They conclude that, in so far as it is easier to bring an action for annulment under Article 173 of the EC Treaty than under Article 33 of the ECSC Treaty, declaring this application inadmissible would amount to a breach of the principle of equal treatment.
14Article 104(3) of the Rules of Procedure requires that an application for suspension of operation of a measure be made by a separate document, which is not the case here. That part of the application must therefore be dismissed as inadmissible (order in Case T-107/94 Kik v Council and Commission [1995] ECR II-1717, paragraph 38).
15Secondly, Article 33 of the ECSC Treaty provides an exhaustive list of the persons entitled to bring an action for annulment of a measure (Case 222/83 Commune de Differdange and Others v Commission [1984] ECR 2889, paragraph 8).
16As regards legal persons in particular, actions for annulment of a measure may be brought under that provision, under certain circumstances, by undertakings or by associations referred to in Article 48 of the ECSC Treaty. In that respect, it should be noted that the associations referred to in Article 48 of the ECSC Treaty are associations of undertakings (Joined Cases 140/82, 146/82, 211/82 and 226/82 Walzstabl-Vereinigung and Thyssen v Commission [1984] ECR 951, paragraph 18).
17It follows that the applicants have no right of action under Article 33 of the ECSC Treaty as they themselves expressly acknowledged in the application.
18Finally the Court considers that Article 173 of the EC Treaty cannot apply to the present application for the annulment of a decision adopted under the ECSC Treaty. In particular, the applicants cannot rely on the principle of equal treatment, by complaining that actions for annulment under Article 173 of the EC Treaty may be brought by a broad group of natural and legal persons, whilst actions under Article 33 of the ECSC Treaty may be brought only by two clearly denned groups of legal persons. It is clear from Article 232 of the EC Treaty that the provisions of that Treaty do not affect those of the ECSC Treaty which, consequently, retain their own scope (see Case 239/84 GerUch v Minister for Economic Affairs [1985] ECR 3507, paragraph 9 and Case 328/85 Deutsche Babcock Handel v HauptzolUmt Lübeck-Ost [1987] ECR 5136, paragraph 10).
19It follows from all the foregoing that the application must be declared inadmissible in its entirety.
