70As regards the claim seeking annulment of the decision ruling on the complaint, it should be borne in mind that, according to settled case-law applicable to legal matters involving the EU civil service, the administrative complaint such as referred to in Article 90(2) of the Staff Regulations and its rejection, whether express or implied, thus constitute an integral part of a complex procedure and are no more than a precondition for bringing the matter before the judicature. Consequently, the action before the judicature, even if formally directed against the rejection of the complaint, has the effect of bringing before the judicature the act adversely affecting the applicant against which the complaint was submitted (judgment of 17 January 1989, Vainker v Parliament, 293/87, EU:C:1989:8, paragraphs 7 and 8), except where the scope of the rejection of the complaint differs from that of the measure against which that complaint was made (judgment of 25 October 2006, Staboli v Commission, T‑281/04, EU:T:2006:334, paragraph 26).
