22The Parliament maintains, as a preliminary point, that, on a literal interpretation of the applicant's letter to it of 27 April 1995 and of the application, the applicant is clearly calling upon the defendant to adopt an approach which is legally impossible and unlawful. The applicant has requested the Parliament to propose to the competent institutions an amendment to the Staff Regulations, and complains of the Parliament's unwillingness to do so. The Parliament contends, however, that it is not competent to submit to the other institutions proposals for the adoption or amendment of legal acts. The only provision which might be read as having that meaning is the second paragraph of Article 138b of the Treaty; however, the applicant has not called for the implementation of that provision.
23The Parliament concedes, nevertheless, that the applicant's request may be interpreted as an attempt to prompt the institution to take such steps as may be appropriate in order that the applicant may be placed in a more favourable legal position. It leaves it to the Court to decide whether such an interpretation accords with the criteria of admissibility laid down in Article 175 of the Treaty.
24The Parliament asserts, in any event, that, even if Article 175 of the Treaty can be used for that purpose, the action is still inadmissible. It advances in that regard one main plea and four alternative pleas.
25As its principal argument, the Parliament pleads that it has not failed to act, inasmuch as the Parliament's position in relation to the applicant's request was expressly denned by the chairman of the Petitions Committee in his letter of 20 July 1995. The admissibility criteria laid down in Article 175 of the Treaty were therefore not fulfilled. Moreover, the fact that the Parliament defined its position after the expiry of the period of two months referred to in Article 175, but before the action was brought, and that it did not satisfy the applicant, is irrelevant to the question of admissibility (Case C-25/91 Pesqueras Echebastar v Commission [1993] ECR I-1719, paragraphs 11 and 12).
26The first plea in the alternative alleges that the act which the institution is said to have failed to address to the applicant is not one which would have been addressed to her. The defendant observes that the third paragraph of Article 175 of the Treaty permits a person to apply for a ruling against an institution for failure to address an act to that person. By contrast, applications for the adoption of legal acts to be addressed to third parties are inadmissible (Case 246/81 Lord Bethell v Commission [1982] ECR 2277, paragraph 13 et seq.; order in Case T-3/90 Prodifarma v Commission [1991] ECR II-1, paragraphs 33 and 34). In the present case, the action should be declared inadmissible in so far as the applicant's request called for steps to be taken in relation to other institutions.
27The second plea in the alternative concerns the nature of the act. Article 175 of the Treaty cannot be relied upon to obtain a ruling against an institution which has declined to adopt a measure of general application, in particular a regulation (Case 15/71 Mackprang v Commission [1971] ECR 797, paragraph 4, Case 134/73 Holtz & Willemsen v Council [1974] ECR 1, paragraph 5, and Case 90/78 Granaria v Council and Commission [1979] ECR 1081, paragraph 14; order in Case 60/79 Fédération Nationale des Producteurs de Vins de Table et Vins de Pays v Commission [1979] ECR 2429). In so far as the present action indirectly seeks the adoption of a regulation relating to the Staff Regulations, it should also be declared inadmissible.
28The third plea in the alternative concerns the binding nature of the act. The Parliament maintains that it is apparent from the third paragraph of Article 175 of the Treaty that the measure sought must be an act which is legally binding on the person calling for its adoption. Nonbinding acts do not fall within the scope of the third paragraph of Article 175 (Case 15/70 Chevalley v Commission [1970] ECR 975, paragraph 13; order in Cases 83/84 and 84/84 N. M. v Commission and Council [1984] ECR 3571, paragraph 10). A measure taken by the Parliament in the procedure for adopting or amending the Staff Regulations would be an act of that kind as regards the applicant. The action should thus be declared inadmissible.
29The fourth plea in the alternative relates to the Parliament's discretion in the exercise of its powers. Even on the assumption that it was under an obligation to act — which it denies — it enjoyed a wide discretion. This is apparent from the fact that there were several different ways of resolving the applicant's problem, of which amendment of the Staff Regulations was but one. The Parliament is covered, therefore, by the case-law on the inadmissibility of actions for failure to act brought by individuals against a refusal by the Commission to initiate infringement proceedings against a Member State, which is designed to safeguard the discretion enjoyed by the Commission in that sphere (order in Case C-371/89 Emrich v Commission [1990] ECR I-1555, paragraph 4 et seq.; orders in Case T-13/94 Century Oils Hellas v Commission [1994] ECR II-431, paragraph 12 et seq., and Cases T-479/93 and T-559/93 Bernardi v Commission [1994] ECR II-1115, paragraph 31).
30In her observations on the objection of inadmissibility, the applicant states, in response to the Parliament's preliminary observation concerning the impossibility of acting on her request, that the aim of that request was to prompt the institution to use all its powers to bring about the amendment of the Staff Regulations. Consequently, her request also related to Article 138b of the Treaty. The second subparagraph of Article 24(1) of the Treaty establishing a Single Council and a Single Commission must therefore be construed as conferring on the Parliament the right to request the Commission to submit appropriate proposals concerning the Staff Regulations.
31In response to the Parliament's main plea, the applicant claims that the conduct of that institution constitutes an unlawful failure to act, inasmuch as it did not take sufficient action with regard to her right to present a petition and disregarded its obligations under the Treaty in relation to cooperation with a view to amending the Staff Regulations. In any event, in the interests of protecting the rights of individuals, the adoption by the Parliament of an act rejecting the applicant's request is not enough to displace her legal interest in bringing proceedings.
32In opposition to the first of the Parliament's pleas in the alternative, the applicant argues that the parallel, emphasized in the relevant case-law, between the forms of action provided for in Articles 173 and 175 of the Treaty, together with the need to protect the individual, may justify upholding the admissibility of an action concerning an act addressed to a third party. She refers in that regard to the Opinion of Advocate General Dutheillet de Lamothe in Mackprang v Commission, cited above. In addition, the applicant claims that the action does not seek the adoption of an act addressed to a third party, inasmuch as it is she who is its potential addressee. The applicant denies that the case-law cited by the defendant is applicable to the present case. This case is concerned with cooperation between the Community institutions, whereas the action in Lord Bethell v Commission concerned the initiation of an investigation in relation to the Member States and the dispute in Prodifarma v Commission related to the mandatory provisions of Article 15 of Regulation No 17 of the Council of 6 February 1962: First Regulation implementing Articles 85 and 86 of the EEC Treaty (OJ, English Special Edition 1959-1962, p. 87), of which Prodifarma was not a potential addressee.
33In response to the second of the pleas in the alternative, the applicant claims that the term ‘act’ in the third paragraph of Article 175 of the Treaty includes regulations, provided that they constitute individual measures. In view of the fact that the act which has not been adopted would be of direct and individual concern to the applicant, inasmuch as the amendment of the Staff Regulations would be directly beneficial to her, that amendment constitutes an individual decision by implication, thus rendering the action admissible.
34As regards the third plea in the alternative, the applicant claims that she is seeking to bring about a legal effect which will directly influence her situation, with the result that the act in question must be binding.
35With regard to the fourth alternative plea advanced by the defendant, the applicant denies that the principles elicited in the case-law on the Commission's discretion with regard to the initiation of infringement proceedings against a Member State are applicable. The Commission and the Parliament perform different functions in the legislative process, and the Commission's discretion cannot therefore be compared with that of the defendant institution. In the present case, the Parliament has no discretion and must, in accordance with the Treaty, choose the most effective means of enabling the applicant to remain covered by the Joint Sickness Insurance Scheme.
36Where an institution to whom a request has been made pursuant to the second paragraph of Article 175 of the Treaty defines its position, even if it does so after the period of two months laid down by the Treaty has expired, the conditions prescribed by that article are not fulfilled (judgment in Pesqueras Echebastar v Commission, paragraph 11).
37In the present case, the Court notes that on 20 July 1995 the Parliament, in the person of the chairman of the Petitions Committee, replied to the applicant's letter of 27 April 1995. In its reply, the Parliament described the representations made to the Commission and the German authorities with a view to resolving the applicant's problem, and stated that there was nothing further that it could do. Having regard to that letter, which set out the steps which had been taken and defined the position of the defendant institution in relation to the applicant's request, the Parliament cannot be said to have failed to act. The fact that the Parliament's reply did not satisfy the applicant is immaterial in that regard. Article 175 of the Treaty refers to failure to act in the sense of failure to take a decision or to define a position, not the adoption of a measure different from that desired or considered necessary by the persons concerned (Joined Cases 166/86 and 220/86 Irish Cement v Commission [1988] ECR 6473, paragraph 17, and Joined Cases C-15/91 and C-108/91 Buckl & Söhne and Others v Commission [1992] ECR I-6061, paragraph 16).
38In those circumstances, it must be stated, without there being any need to determine whether the Parliament was empowered in the present case to adopt the measures sought by the applicant, that there has been no failure to act on its part.
39In any event, and for the sake of completeness, the Court observes that natural or legal persons may have recourse to the third paragraph of Article 175 of the Treaty only for a declaration that the institution has failed to adopt acts of which they are the potential addressees, thereby infringing the Treaty {Bernardi v Commission, cited above, paragraph 31). The acts which, according to the applicant, the Parliament failed to adopt would not in any event have been addressed to her.
40The action must therefore be dismissed as inadmissible.
