APPLICATION under Article 270 TFEU for annulment of the decisions of the Commission by which the appointing authority of that institution classified the applicants in the type of post administrator in transition or administrator resulting in the loss, with effect from 1 January 2014, of eligibility for promotion to a higher grade, as those decisions were confirmed by the decisions of the appointing authority of 3 July, 17 July and 6 August 2014,

THE GENERAL COURT (First Chamber),

composed of I. Pelikánová, President, P. Nihoul and J. Svenningsen (Rapporteur), Judges,

Registrar: M. Marescaux, Administrator,

having regard to the written part of the procedure and further to the hearing on 17 October 2018,gives the following<TI><P><HT TYPE="BOLD">Judgment</HT></P></TI><TI><P><HT TYPE="BOLD">Background to the dispute</HT></P></TI>1FZ and the nine other applicants whose names appear in the annex are grade AD 12 or AD 13 officials of the European Commission in the administrators’ (AD) function group.2It is apparent from Section A of Annex I to the Staff Regulations of Officials of the European Union in the version in force from 1 May 2004 to 31 December 2013 (the 2004 Staff Regulations) that officials in the administrators’ function group, classified in accordance with Article 5 of the Staff Regulations, could progress from grade AD 5 to grade AD 14, by way of promotion under Article 45 of the Staff Regulations, which shall be effected by appointment of the official to the next higher grade in the function group to which he belongs, and shall be exclusively by selection from among officials who have completed a minimum of two years in their grade after consideration of the comparative merits of the officials eligible for promotion. Accordingly, pursuant to the 2004 Staff Regulations, grade AD 12 or AD 13 officials occupying the post of administrator were eligible for promotion to a higher grade under Article 45 of those regulations.3Regulation (EU, Euratom) No 1023/2013 of the European Parliament and of the Council of 22 October 2013 amending the Staff Regulations of Officials of the European Union and the Conditions of Employment of Other Servants of the European Union (OJ 2013 L 287, p. 15) entered into force on 1 November 2013. Recitals 17, 18 and 19 of that regulation are worded as follows:

(17)The Council requested from the Commission a study and the submission of appropriate proposals on Article 5(4), Annex I, Section A, and Article 45(1) of the [2004] Staff Regulations with a view to establishing a clear link between responsibilities and grade and in order to ensure a greater emphasis on the level of responsibilities when comparing merits in the context of promotion.(18)Taking that request into account, it is appropriate that promotion to a higher grade should be made conditional on personal dedication, improvement of skills and competences, and the performance of duties the importance of which justifies the official’s appointment to that higher grade.(19)The career stream in the [administrators’ (AD) and assistants’ (AST)] function groups should be restructured in such a way that the top grades will be reserved for a limited number of officials exercising the highest level of responsibilities. Therefore administrators can only progress as far as grade AD 12 unless they are appointed to a specific post above that grade, and grades AD 13 and 14 should be reserved for those staff whose roles entail significant responsibilities. Similarly, officials in grade AST 9 can be promoted to grade AST 10 only in accordance with the procedure laid down in Article 4 and Article 29(1) of the Staff Regulations.

4Article 5(4) of the Staff Regulations, in the version in force from 1 January 2014 (the new Staff Regulations or the Staff Regulations), provides:

A table showing types of posts is given in Annex I, Section A [of the new Staff Regulations]. By reference to that table, the appointing authority of each institution may define in more detail the duties and powers attaching to each type of post after consulting the Staff Regulations Committee.

5It is apparent from point 1 of Section A of Annex I to the new Staff Regulations, which is entitled Types of posts in each function group, as provided for in Article 5(4), that, with regard to the AD function group:

officials newly appointed to the type of post administrator may progress from grade AD 5 to grade AD 12;

officials newly appointed to the type of post head of unit or equivalent may progress from grade AD 9 to grade AD 14; and

officials newly appointed to the type of post adviser or equivalent may progress from grade AD 13 to grade AD 14.

6Article 45 of the 2004 Staff Regulations was also amended by the addition, in the version of that provision set out in the new Staff Regulations, of the following sentence: Unless the procedure laid down in Articles 4 and 29(1) [of the Staff Regulations] is applied, officials may only be promoted if they occupy a post which corresponds to one of the types of posts set out in Annex I, Section A, for the next higher grade.7In the context of transitional measures set out in Annex XIII to the new Staff Regulations, Article 30 of that annex provides in paragraph 1 thereof:

By way of derogation from Annex I, Section A, point [1], the following table of types of posts in function group AD shall apply to officials in service on 31 December 2013:

[…][…]Head of unit or equivalentAD 9 – AD 14Adviser or equivalentAD 13 – AD 14Senior Administrator in transitionAD 14Administrator in transitionAD 13AdministratorAD 5 – AD 12

8Paragraphs 2, 3 and 4 of Article 30 of Annex XIII to the new Staff Regulations are worded as follows:

2.

With effect from 1 January 2014, the appointing authority shall classify officials in service on 31 December 2013 in function group AD in types of posts as follows:

…

(b)Officials who were in grade AD 13 on 31 December 2013 and who were not []Head of unit or equivalent[] or []Adviser or equivalent[] shall be assigned to the type of post []Administrator in transition[].(c)Officials who were in grades AD 9 to AD 14 on 31 December 2013 and who were []Head of unit or equivalent[] shall be assigned to the type of post []Head of unit or equivalent[].(d)Officials who were in grades AD 13 or AD 14 on 31 December 2013 and who were []Adviser or equivalent[] shall be assigned to the type of post []Adviser or equivalent[].(e)Officials who were in grades AD 5 to AD 12 on 31 December 2013 and who were not []Head of unit or equivalent[] shall be assigned to the type of post []Administrator[].

3.By way of derogation from paragraph 2, officials in grades AD 9 to AD 14 holding special responsibilities may be assigned by the appointing authority before 31 December 2015 to the type of post Head of unit or equivalent or Adviser or equivalent. Each appointing authority shall lay down provisions to give effect to this Article. However, the total number of officials benefiting from this provision shall not exceed 5% of the officials in function group AD on 31 December 2013.4.The assignment to a type of post shall be valid until the official is assigned to a new function corresponding to another type of post.

9On 16 December 2013, the Commission adopted Decision C(2013) 8968 final laying down general provisions for implementing Article 45 of the new Staff Regulations, published in Administrative Notices No 55-2013 of 19 December 2013. Under the second indent of Article 3 of those general implementing provisions, officials may be promoted [only] if … at the time of the launch of the promotion exercise …, they occupy a post which corresponds to one of the types of post set out in Annex I, Section A, or in Article 30(1) or Article 31(1) of Annex XIII to the [new] Staff Regulations for the grade to which they may be promoted.10Following the taking effect, on 1 January 2014, of the measures referred to in paragraphs 3 to 9 above, the grade AD 12 applicants were assigned to the type of post administrator, meaning that their career path allows for progression only between grades AD 5 and AD 12, whereas the grade AD 13 applicants were assigned to the type of post administrator in transition such that they were not eligible for promotion to a higher grade. On 30 December 2013, the appointing authority of the Commission thus amended, in the human resource management information system known as SysPer 2, the applicants’ individual files indicating their assignment to the new type of post held with the result that, from 1 January 2014, they were no longer eligible for promotion to a higher grade.11Between 12 and 31 March 2014, eight of the applicants each submitted a complaint in accordance with Article 90(2) of the Staff Regulations against the decisions of the appointing authority, both of general and of individual application, blocking any possibility of promotion for the applicants to a higher grade in the context of the annual promotion exercise provided for under Article 45 of the Staff Regulations.12On 11 and 24 April 2014 respectively, the other two applicants, namely GH and GC, each submitted a similar complaint.13By decisions of 3 July 2014, written in identical terms, the appointing authority rejected the applicants’ complaints submitted between 12 and 31 March 2014, with the exception of the complaint submitted by GK which had been rejected by decision of the appointing authority of 17 July 2014. In addition, by decision of 6 August 2014, the appointing authority rejected the complaints of 11 and 24 April 2014.<TI><P><HT TYPE="BOLD">Procedure and forms of order sought</HT></P></TI>14By application lodged at the Registry of the European Union Civil Service Tribunal on 20 October 2014 and initially registered under number F‑113/14, the applicants brought the present action.15By decision of 26 November 2014, the President of the Third Chamber of the Civil Service Tribunal decided, after hearing the parties, to stay the proceedings until the decisions closing the proceedings in U4U and Others v Parliament and Council (T‑17/14) and USFSPEI v Parliament and Council (T‑75/14) had become final.16On 10 December 2014 and 20 January 2015 respectively, the Council of the European Union and the European Parliament applied, pursuant to Article 86 of the Rules of Procedure of the Civil Service Tribunal, for leave to intervene in support of the form of order sought by the Commission. They were informed in that regard that their applications would be dealt with once the proceedings had resumed.17Pursuant to Article 3 of Regulation (EU, Euratom) 2016/1192 of the European Parliament and of the Council of 6 July 2016 on the transfer to the General Court of jurisdiction at first instance in disputes between the European Union and its servants (OJ 2016 L 200, p. 137), the present case was transferred to the General Court as it stood on 31 August 2016 and must henceforth be dealt with in accordance with the Rules of Procedure of the General Court. The case was accordingly registered under number T‑526/16 and assigned to the First Chamber.18Following the delivery of the judgment by the Court on 15 September 2016 in U4U and Others v Parliament and Council (T‑17/14, not published, EU:T:2016:489) and the judgment of 16 November 2017 in USFSPEI v Parliament and Council (T‑75/14, EU:T:2017:813), and the fact that no appeal had been brought against those decisions within the time limit provided for in Article 56 of the Statute of the Court of Justice of the European Union, the proceedings were resumed in the present case and the Commission was invited to lodge a defence which it did within the prescribed time limit, on 17 April 2018.19By decision of 19 April 2018, the Parliament and the Council were, in accordance with Article 144 of the Rules of Procedure, granted leave to intervene in support of the form of order sought by the Commission.20On 31 May 2018, the applicants lodged the reply in the context of the second exchange of pleadings which had been authorised by the Court.21On 31 May 2018, the Parliament and Council submitted statements in intervention, in respect of which the main parties made no observations.22Following the submission, in FZ and Others v Commission (T‑540/16), of an application for joinder of that case with the present case, the parties were given an opportunity to be heard in that regard and raised no objections.23Following the lodging of the rejoinder on 17 July 2018, the written part of the procedure was closed.24By decision of 18 September 2018, the parties having been heard, the present case was joined to Cases T‑525/16 (GQ and Others v Commission) and T‑540/16 (FZ and Others v Commission) for the purposes of the oral procedure.25The parties presented oral argument at the hearing on 17 October 2018. At the hearing, the Court asked the Commission to provide it, within two weeks, with certain information on the applicants’ current position under the Staff Regulations. Following the reply sent by the Commission on 31 October 2018 and the applicants’ observations of 13 November 2018, the oral part of the procedure was closed.26The applicants claim that the Court should:

primarily:

declare Article 45 of the new Staff Regulations and Annex I thereto, together with the corresponding transitional provisions, unlawful;

annul the decisions of the appointing authority, both of general and of individual application, to block any possibility of promotion concerning the applicants, as grade AD 12 or AD 13 officials, in the context of the 2014 annual promotion exercise;

order the Commission to pay the costs;

in the alternative:

annul the decisions of the appointing authority, of both general and individual and of a general scope, to block any possibility of promotion concerning the applicants, as grade AD 12 or AD 13 officials, in the context of the 2014 annual promotion exercise;

order the Commission to pay the costs.

27The Commission contends that the Court should:

dismiss the action;

order the applicants to pay the costs.

28The Parliament contends that the Court should reject the arguments of the applicants seeking a declaration that Article 45 of the new Staff Regulations and Annex I thereto, together with the corresponding transitional provisions, are inapplicable.29The Council contends that the Court should:

dismiss the action;

order the applicants to pay the costs.

<TI><P><HT TYPE="BOLD">Law</HT></P></TI><TI><P><HT TYPE="BOLD"><HT TYPE="ITALIC">Admissibility of the action</HT></HT></P></TI>30As a preliminary point, whilst concluding that the action is admissible, the Commission notes that, in actual fact, the action concerns only the decisions of the appointing authority assigning the applicants, as the case may be, to the types of post administrator in transition or administrator with effect from 1 January 2014. It observes, however, that although eight of the applicants submitted complaints against the acts adversely affecting them within the period prescribed, the same cannot be said for GH and GC. With regard to the latter, however, the Commission takes the view, in the light of paragraph 57 of the order of 16 July 2015 in FG v Commission (F‑20/15, EU:F:2015:93), that their complaints were submitted within three months from the communication of 14 April 2014.31In that regard, since the existence of an act adversely affecting an applicant within the meaning of Article 90(2) and Article 91(1) of the Staff Regulations is an essential requirement for the admissibility of any action brought by officials against the institution in which they serve, it is necessary, in the circumstances of the present case, to determine, first of all, which acts the applicants intend to challenge by means of this action and to assess whether they constitute acts adversely affecting them (see, to that effect, judgment of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 39, and order of 16 July 2015, FG v Commission, F‑20/15, EU:F:2015:93, paragraph 43). Then, since the admissibility of an action brought before the Court under Article 270 TFEU and Article 91 of the Staff Regulations is subject to the proper conduct of the pre-litigation procedure and will depend on compliance with the set time limits (see judgment of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 36 and the case-law cited), it will be necessary to determine whether, for each of the applicants, they submitted their respective complaints within the time limit provided for in Article 90(2) of the Staff Regulations.32In that regard, officials occupying an administrator post in grades AD 5 to AD 13 on 31 December 2013 could be assigned to different types of post such as administrator in transition, administrator, adviser or equivalent or head of unit or equivalent (see, to that effect, judgments of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 40, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 43).33Accordingly, the decisions of the appointing authority to assign the applicants, as the case may be, to the types of post administrator in transition or administrator took effect on 30 December 2013, as indicated by a reference made to the assignment of the applicants to those types of post in the applicants’ individual files in SysPer 2 (the contested decisions), adversely affect them, in so far as they lose, with effect from 1 January 2014, their eligibility for promotion to a higher grade (see, to that effect, judgments of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 42 and the case-law cited, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 45).34In addition, as acknowledged by the Commission, with the exception of GH and GC, those decisions were challenged by the applicants by way of complaints brought against them within a period of three months in accordance with Article 90(2) of the Staff Regulations.35As regards the two applicants who submitted their complaints on 24 and 11 April 2014 respectively, they can no longer be regarded as having been submitted out of time in the light of the three-month time limit provided for in Article 90(2) of the Staff Regulations. It is clear that the Commission is unable to confirm the dates on which the applicants in question became aware of the amendment, of 30 December 2013, made to their individual files in SysPer 2 on the ground that, in breach of Articles 25 and 26 of the Staff Regulations, it failed to notify the applicants of those decisions relating to them (see, to that effect, order of 16 July 2015, FG v Commission, F‑20/15, EU:F:2015:93, paragraph 46 and the case-law cited).36In such circumstances, it should be acknowledged that, even if the two applicants in question were aware before 24 and 11 January 2014 respectively of the amendment of type of post occupied made to their individual files in SysPer 2, the form in which those decisions had been communicated to them may have been misleading (see, to that effect, judgment of 5 April 1979, Orlandi v Commission, 117/78, EU:C:1979:109, paragraph 11).37In those circumstances, the present action must be declared admissible, in so far as it concerns the contested decisions. Furthermore, given the evolving nature of the pre-litigation procedure, the reasons given in the decisions rejecting the applicants’ complaints must be taken into account, since those reasons are deemed to be the same as those on which the contested decisions are based (see, to that effect, judgments of 9 December 2009, Commission v Birkhoff, T‑377/08 P, EU:T:2009:485, paragraphs 58 and 59, and of 16 January 2018, SE v Council, T‑231/17, not published, EU:T:2018:3, paragraph 22).<TI><P><HT TYPE="BOLD"><HT TYPE="ITALIC">The claim for a declaration of unlawfulness of certain provisions of the Staff Regulations</HT></HT></P></TI>38With regard to the claim that the Court should declare Article 45 of the new Staff Regulations and the corresponding transitional provisions unlawful, it should be borne in mind that, while it is true that, in the context of a claim for annulment of a decision of individual application concerning him, an official or other member of staff, that official or other member of staff may, under Article 277 TFEU, invoke the unlawfulness of an act of general application on the basis of which that decision was adopted. Only the Courts of the European Union are entitled, under the terms of Article 277 TFEU, to rule that an act of general application is unlawful and to draw the consequences of the inapplicability which results from this with regard to the act of individual scope contested before them (judgment of 27 October 2016, ECB v Cerafogli, T‑787/14 P, EU:T:2016:633, paragraph 49).39However, the finding of illegality made by the EU Courts in accordance with Article 277 TFEU does not have erga omnes effect since, while it entails the illegality of the individual contested decision, it leaves the act of general application in the legal order without affecting the legality of other acts which have been adopted pursuant thereto and which were not challenged within the period for appeal (see, to that effect, judgments of 21 February 1974, Kortner and Others v Council and Others, 15/73 to 33/73, 52/73, 53/73, 57/73 to 109/73, 116/73, 117/73, 123/73, 132/73 and 135/73 to 137/73, EU:C:1974:16, paragraphs 37 and 38, and of 27 October 2016, ECB v Cerafogli, T‑787/14 P, EU:T:2016:633, paragraph 53).40It follows that, in the context of a claim for annulment of an act of individual application having adverse effect, the Courts of the European Union do in fact have jurisdiction to establish, in passing, the unlawfulness of a provision of general application on which the contested act is based. However, they do not have jurisdiction to make such a declaration in the operative part of their judgments (see, to that effect, judgment of 21 October 2009, Ramaekers-Jørgensen v Commission, F‑74/08, EU:F:2009:142, paragraph 37).41Consequently, as the Commission rightly submits, the claim that the Court should declare unlawful Article 45 of the new Staff Regulations and Annex I thereto, together with the corresponding transitional provisions, must, in so far as it is not part of a plea of illegality raised under Article 277 TFEU seeking the annulment of the contested decisions, be declared manifestly inadmissible.<TI><P><HT TYPE="BOLD"><HT TYPE="ITALIC">The claim for annulment</HT></HT></P></TI>42In support of the claim for annulment, the applicants raise, principally, a single plea in law, alleging that Article 45 of the new Staff Regulations and Annex I thereto are unlawful. In the alternative, they raise two other pleas in law, the first relating to the infringement of Article 45 and the existence of a manifest error of assessment, and the second relating to the infringement of the obligation to state reasons.43The Commission, supported by the Parliament and the Council, contends that all of those pleas in law should be rejected as unfounded.<TI><P><HT TYPE="ITALIC">The first plea in law, alleging that Article 45 of the new Staff Regulations and Annex I thereto are unlawful</HT></P></TI>44According to the applicants, the system established under the new Staff Regulations making it impossible for grade AD 12 or AD 13 officials assigned to the types of post administrator or administrator in transition’ to be promoted to a higher grade under Article 45 of the new Staff Regulations, breaches the principle of equal treatment, the principle that officials should have reasonable career prospects, the principle of proportionality and the duty to have regard for the welfare of officials. In that context, they submit that, at the time of their recruitment, they were eligible for promotion to grade AD 14 without restriction. Accordingly, Article 45 of the new Staff Regulations and Annex I thereto infringed their acquired rights. They thus invoke the unlawfulness of Article 45 of the new Staff Regulations and Annex I thereto.45The Commission, supported by the Parliament and the Council, contends that the plea of illegality should be rejected as unfounded.46The first plea in law is broken down into six parts which will be examined in turn.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The first part of the first plea in law, relating to the breach of the principle of equal treatment and the principle that officials should have reasonable career prospects</HT></TXT></NP></TI>47In support of the first part of the first plea in law, the applicants claim that, under Article 5(5) of the Staff Regulations, which provides that identical conditions of recruitment and service career shall apply to all officials belonging to the same function group, the EU legislature infringed the principle of equal treatment and the principle that officials should have reasonable career prospects.48In that regard, the applicants consider that, by stating in Article 45 of the new Staff Regulations that unless the procedure laid down in Articles 4 and 29(1) [of the Staff Regulations] is applied, officials may only be promoted if they occupy a post which corresponds to one of the types of posts set out in Annex I, Section A, for the next higher grade, the EU legislature infringed the principle of equal treatment and the principle that officials should have reasonable career prospects by confining the applicants to the types of post administrator or administrator in transition thus blocking any possibility of promotion to a higher grade, with that grade being reserved for officials occupying the types of post head of unit or equivalent or adviser or equivalent.49According to the applicants, they will be treated differently to administrators in the same function group as them, since grade AD 5 to AD 11 administrators and grade AD 9 to AD 13 administrators performing the duties of a head of unit or equivalent or adviser or equivalent continue to be eligible for promotion based on a comparison of merits over time of officials holding such grades and types of posts whereas, in the case of the applicants, their promotion to grades AD 13 or AD 14 is possible only in accordance with the procedure set out in Article 4 and Article 29(1) of the Staff Regulations, which does not allow for promotion based on the demonstration of merits over time, since it is essentially based on the assessment of the competences of administrators wishing to be appointed to a vacant head of unit or equivalent or adviser or equivalent post.50In addition, whilst administrators of lower grades – AD 5 to AD 11 – are guaranteed promotion in the light of the number of promotions authorised annually by the appointing authority within the institution, the applicants face uncertainty as regards the number of vacancies for heads of unit or equivalent or advisers or equivalent that the appointing authority will decide to fill annually in accordance with the procedure set out in Article 4 and Article 29(1) of the Staff Regulations. Moreover, in the context of the appointment procedure for such posts, the appointing authority has more discretion than in the context of the promotion procedure, in particular due to the lack of input from the Joint Promotion Committee. The applicants add that, in the context of the appointment procedure, they are in competition not only with other Commission administrators, in the same way as for the comparison of merits carried out under the promotion procedure, but also with administrators from other institutions, which reduces the likelihood of promotion.51In that regard, it should be borne in mind that the legal link between an official and the administration is based upon the Staff Regulations and not upon a contract (see, to that effect, judgment of 19 March 1975, Gillet v Commission, 28/74, EU:C:1975:46, paragraph 4). Accordingly, the rights and obligations of officials may be altered at any time by the EU legislature and, in that context, amending legislation, such as the regulations amending the Staff Regulations adopted under Article 336 TFEU, applies, unless otherwise provided, to the future consequences of situations which arose under the previous legislation. That is so except for situations originating and becoming definitive under the previous legislation, which create acquired rights (judgments of 22 December 2008, Centeno Mediavilla and Others v Commission, C‑443/07 P, EU:C:2008:767, paragraphs 60 to 62, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 58).52According to the case-law, in the context of the reform of the Staff Regulations, a right is considered to be acquired only when the event giving rise to it occurred before the legislative amendment but that is not the case when the event creating the right did not take place under the legislation that has been amended. Accordingly, where, as in the present case, officials had, until the date on which the new Staff Regulations entered into force, only been eligible for promotion subject to a decision of the appointing authority promoting them to a higher grade which it had not yet adopted, in the present case on 1 January 2014, such officials cannot claim an acquired right to remain eligible for that promotion after that date (see, to that effect, judgments of 22 December 2008, Centeno Mediavilla and Others v Commission, C‑443/07 P, EU:C:2008:767, paragraphs 63 to 65, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 59).53In addition, officials cannot rely on the principle of protection of legitimate expectations in order to oppose the application of a new legislative provision, especially in a sphere in which the legislature enjoys a considerable degree of latitude (judgments of 22 December 2008, Centeno Mediavilla and Others v Commission, C‑443/07 P, EU:C:2008:767, paragraph 91, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 60). Accordingly, the applicants’ arguments relating to the breach of the principle of legitimate expectations and the alleged acquired rights to their continued eligibility for promotion to a higher grade, owing to the limitation allegedly placed on their career progression by the EU legislature and/or the Commission and on account of their assignment to the types of post administrator or administrator in transition, must be rejected.54Next, it should be noted that, in view of the wide discretion conferred on the EU legislature, the latter was legitimately entitled to consider, in recital 19 of Regulation No 1023/2013 and in point 1 of Section A of Annex I to the new Staff Regulations, that grades AD 13 and AD 14 should henceforth be reserved for a limited number of officials, in this case administrators exercising the highest level of responsibilities within the meaning of that recital, that is to say significant responsibilities.55In particular, contrary to what the applicants’ claim, the EU legislature was entitled to consider that access to a grade AD 13 or AD 14 post should no longer be possible in the context of a promotion procedure for administrators under Article 45 of the 2004 Staff Regulations which, according to the case-law, seeks to adjust the career progress of officials according to the effort they have made and the merits they have demonstrated, including over time (judgments of 11 July 2007, Konidaris v Commission, T‑93/03, EU:T:2007:209, paragraph 91, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 72), but should henceforth take place under the appointment procedure provided for in Article 4 and Article 29(1) of the Staff Regulations.56That procedure for filling a vacant post provided for in Article 29(1) of the Staff Regulations concerns, according to that case-law, the search, in the interests of the service, of the official, within the institution or in other institutions, for the official who is best able to perform the duties involved in the post to be filled. In view of the EU legislature’s objective of streamlining public expenditure and strengthening the correlation between functions and grade, the latter was entitled to consider that such a procedure was likely to enable the appointing authority to entrust the most significant and highest level of responsibilities to a limited number of officials with the most appropriate professional skills, in the present case to administrators exercising the responsibilities of a head of unit or equivalent and adviser or equivalent which are objectively more significant than those of lower grade administrators.57It should also be pointed out that the appointing authority has wide discretion in the organisation and structuring of its services and, therefore, the level of responsibilities it considers necessary to entrust to its officials and agents (see judgment of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 81 and the case-law cited), meaning that it is free, under the supervision of the budgetary authority, to determine and streamline the number of heads of unit or equivalent and advisers or equivalent it needs.58In that regard, contrary to what the applicants argue, the modifications to the Staff Regulations on the career structure for administrators do not conflict with the retention of Article 5(5) in the new Staff Regulations according to which identical conditions of recruitment and service career shall apply to all officials belonging to the same function group. Within the framework of the new Staff Regulations, regardless of the date of recruitment or entry into service, administrators are all subject to identical conditions as regards career progress, that is to say career progression up to grade AD 12 under the promotion procedure provided for in Article 45 of the new Staff Regulations and, if they wish to progress beyond that grade, the possibility to do so by filling posts involving significant responsibilities following the procedure provided for in Article 4 and Article 29(1) of the new Staff Regulations, organised in order to fill head of unit or equivalent or adviser or equivalent posts.59So far as concerns the principle that officials are entitled to reasonable career prospects, it should also be borne in mind that EU law does not specifically enshrine either a principle of continuity of career or a principle of entitlement to a career. By contrast, the case-law has set out the principle of career progression as the specific form of the principle of equal treatment applicable to officials (judgment of 5 March 2008, Toronjo Benitez v Commission, F‑33/07, EU:F:2008:25, paragraphs 87 and 88, and order of 27 September 2011, Lübking and Others v Commission, F‑105/06, EU:F:2011:152, paragraphs 81 and 82).60In that regard, it is apparent from Article 5(5) of the Staff Regulations that identical conditions of recruitment and service career shall apply to all officials belonging to the same function group. However, it follows from Article 45 of the new Staff Regulations that the EU legislature decided that, from 1 January 2014, unless the procedure laid down in Articles 4 and 29(1) is applied, officials may only be promoted if they occupy a post which corresponds to one of the types of posts set out in [Section A of Annex I to the Staff Regulations], for the next higher grade. Accordingly, as is apparent from recital 19 of Regulation No 1023/2013, the EU legislature intended, in the implementation of Article 5(5) of the Staff Regulations, which requires identical conditions of recruitment and service career for all administrators, to restructure the career stream in the administrators’ function group by retaining a basic career stream for administrators allowing for progress between grades AD 5 and AD 12 and, thereafter, specific career streams reserved for those exercising significant responsibilities such as those of heads of unit or equivalent or advisers or equivalent, allowing access to the highest grades, that is to say AD 13 and AD 14.61As the Council observes, by henceforth requiring that, unless the procedure provided for in Article 4 and Article 29(1) of the Staff Regulations applies, officials may be promoted only if they occupy a post corresponding to one of the types of post for the next higher grade, the EU legislature provided for a restriction which applies indiscriminately to all function groups and, within those groups, to all administrators and assistants, regardless of the date of recruitment or entry into service.62In any event, there is a breach of the principle of equal treatment, a general principle of EU law enshrined in Articles 20 and 21 of the Charter of Fundamental Rights of the European Union and applicable to EU civil service law, only where two categories of persons whose factual and legal situations are not essentially different receive different treatment in their classification and where that difference in treatment is not objectively justified. When that principle is applied, the situations to be compared must be examined taking account of all the factors characterising those situations (judgment of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 65; see also, to that effect, judgments of 22 December 2008, Centeno Mediavilla and Others v Commission, C‑443/07 P, EU:C:2008:767, paragraph 76; of 15 November 2011, Nolin v Commission, T‑58/11 P, EU:T:2011:664, paragraphs 37 and 38).63It is therefore necessary to determine whether grade AD 12 or AD 13 officials assigned to the types of post administrator or administrator in transition are in a comparable situation to that of administrators occupying lower grade posts – AD 5 to AD 11 – and that of officials belonging to the same function group but who perform the duties of a head of unit or equivalent or adviser or equivalent who, unlike the applicants, remain eligible for promotion beyond grade AD 12 or AD 13 under Article 45 of the Staff Regulations.64As for administrators in grade AD 5 to AD 11 who, like the applicants, do not perform the duties of a head of unit or equivalent or adviser or equivalent, it must be found that they are objectively not in the same situation as that of grade AD 12 or AD 13 officials, like the applicants, performing the duties of administrators since, unlike the latter, they have not yet reached the maximum grade for the type of post in which they have prospects for progression.65According to the case-law, the principle of equal treatment means that all officials promoted to the same grade should, where their merits are equal, have the same chance of promotion to the higher grade (see judgment of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 70 and the case-law cited).66Accordingly, it is now necessary to compare the situation of the applicants with that of grade AD 12 or AD 13 officials who perform the duties of a head of unit or equivalent or adviser or equivalent.67In that regard, given the nature of the duties performed by heads of unit, which are substantially more significant than those performed by administrators who report directly to those heads of unit, the applicants cannot claim that they are in a situation comparable to that of the heads of unit in question, in the present case those occupying grade AD 12 or AD 13 posts.68With regard to advisers or equivalent, it is apparent from the case-law that they, together with heads of unit or equivalent or officials recruited by the Commission for the specific post of senior expert, must perform different or additional duties in relation to those performed by administrators or even exercise supervisory responsibilities, resulting in significant responsibilities or possibly responsibilities that are more significant than before, which are such as to justify that, within the framework of the new Staff Regulations, legal advisers and senior experts occupy the post adviser or equivalent at grade AD 13 with the possibility of promotion to grade AD 14, contrary to the situation of administrators at grade AD 12 or AD 13 (see, to that effect, judgment of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 74).69In any event, the Court considers that the applicants, including those performing the duties of a deputy head of unit, have failed to demonstrate that the duties performed on 31 December 2013 were as significant or more significant than those performed by heads of unit or advisers at the same grade.70In the light of the foregoing considerations, the first part of the first plea in law must be rejected.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The second part of the first plea in law, relating to a breach of the principle of proportionality</HT></TXT></NP></TI>71In support of the second part of the first plea in law, the applicants claim that blocking any possibility of promotion beyond grades AD 12 or AD 13 as a result, in their opinion, of the new provisions of the Staff Regulations, is disproportionate in the light of the stated objective of the EU legislature to reserve the top grades for a limited number of officials exercising the highest level of responsibilities. On the one hand, such an objective was already fulfilled by blocking, under the 2004 Staff Regulations, access to grades AD 15 and AD 16 by administrators, since those grades were reserved for directors and directors-general only. On the other, the measure at issue in the present case cannot be considered an appropriate means of attaining the alleged objective, since the appointing authority could re-evaluate annually the number of grades considered to be reserved for senior officials in head of unit or equivalent or adviser or equivalent posts and, in doing so, unjustifiably reduce the career prospects of officials in the administrators’ function group who may not progress beyond grade AD 12 without being appointed to those types of posts.72In that regard, it should be borne in mind that the principle of proportionality requires that measures adopted by EU institutions do not exceed the limits of what is appropriate and necessary in order to attain the objectives legitimately pursued by the legislation in question; when there is a choice between several appropriate measures recourse must be had to the least onerous, and the disadvantages caused must not be disproportionate to the aims pursued. With regard to judicial review of compliance with those conditions the Court has accepted that in the exercise of the powers conferred on it the EU legislature must be allowed a broad discretion in areas in which its action involves political, economic and social choices and in which it is called upon to undertake complex assessments and evaluations. Thus the criterion to be applied is not whether a measure adopted in such an area was the only or the best possible measure. Where the EU legislature has a wide discretion, which is the case when adopting, under Article 336 TFEU, modifications to the Staff Regulations and the Conditions of Employment of Other Servants, its legality can be affected only if the measure is manifestly inappropriate having regard to the objective which the competent institution is seeking to pursue (judgment of 26 February 2016, Bodson and Others v EIB, T‑240/14 P, EU:T:2016:104, paragraphs 116 and 117).73In the present case, it is apparent that, with regard to the provisions of the reform, which entered into force on 1 January 2014 and which are at issue in the present case, the EU legislature set itself the legitimate objective of ensuring that promotion to a higher grade is subject to personal dedication, improvement of skills and competences and the performance of official duties the importance of which justifies the appointment of the official to that higher grade.74The EU legislature sought to improve the unsatisfactory state of affairs identified within the EU Civil Service whereby a clear link could not necessarily be established between the responsibilities and the grade of officials. In that regard, it is apparent in particular from the Commission’s Report of 30 March 2011 to the European Parliament and the Council on equivalence between old and new career structures (COM(2011) 171 final) that the … career structure [of the 2004 Staff Regulations] [could] have greater effects as regards salary structure within Units than originally anticipated and that for example, it [was] not impossible that a head of Unit might earn less than all other officials working in his or her Unit, including his or her secretary[; and that] Heads of Unit [could] be appointed at grade AD 9, whereas administrators [could] reach grade AD 14 (i.e. five grades more as opposed to only one grade more under the previous Staff Regulations) and secretaries/clerks grade AST 11 (two grades more than the entry grade of Heads of Units).75According to the EU legislature, the focus should therefore be more on the level of responsibilities when considering comparative merits in the context of promotion. In short, it is clear from Regulation No 1023/2003 that the EU legislature sought to put an end to the possibility provided for under the 2004 Staff Regulations of officials being inexorably promoted to the highest grades without having to establish a link between their responsibilities and the grade held, which may have resulted in officials in the administrators’ function group being appointed to grades AD 13 or AD 14 without necessarily undertaking high-level or additional responsibilities.76In the light of that legitimate objective, the EU legislature was entitled, without disregarding the principle of proportionality, to consider that grades AD 13 and AD 14, creating an entitlement to a particularly high level of remuneration, should be henceforth reserved for administrators carrying a high level of responsibility. Such a measure appears appropriate in order to remedy the lack of connection identified between, on the one hand, the high grade to which some administrators have been appointed under the promotion procedure provided for in Article 45 of the 2004 Staff Regulations, which is essentially based on merits over time and not on the competences and skills of the officials in question and, on the other, the level of responsibilities entrusted to those officials which are less significant than those exercised by heads of unit or advisers and which may not have varied over time.77The fact, put forward by the applicants, that, so far as concerns the administrators’ function group, grades AD 15 and AD 16 were, under the 2004 Staff Regulations, reserved only for directors or directors-general is irrelevant. Moreover, it should be noted that, in the context of the reform which entered into force in 2014, the EU legislature sought to exclude access to the highest grades only through the promotion procedure provided for in Article 45 of the new Staff Regulations both for administrators, who can no longer access grades AD 13 and AD 14 through that procedure alone, and assistants or assistants in transition for whom access to grades AST 10 and AST 11 through the promotion procedure alone is also henceforth excluded in favour of the appointment-promotion mechanism for the post of senior assistant under the procedure provided for in Article 4 and Article 29(1) of the Staff Regulations.78In the light of the foregoing, the second part of the first plea in law must be rejected as unfounded.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The third part of the first plea in law, relating to the breach of the principle of sound administration and the duty to have regard for the welfare of officials</HT></TXT></NP></TI>79Under the third part of the first plea in law, the applicants claims that, by adopting the contested decisions, the appointing authority failed to take sufficient account of their interests, thus breaching the principle of sound administration and the duty to have regard for the welfare of officials. In addition, they criticise the fact that from now on they will once again be subjected to aptitude tests to establish their ability to perform the duties of a head of unit or equivalent or adviser or equivalent even though they have not changed function group, the appointing authority already subjected them to such tests at the time of their recruitment and they have demonstrated their merits throughout their careers.80So far as concerns the breach, alleged by the applicants, of the principle of sound administration and the duty to have regard for the welfare of officials, it must be held that the appointing authority is not entitled, in accordance with those principles, to disregard the provisions of the Staff Regulations adopted by the EU legislature, which are, as such, binding on the appointing authority in the same way as the appointing authorities of other institutions, bodies, offices and agencies of the European Union. In particular, the duty to have regard for the welfare of officials cannot be interpreted as requiring the appointing authority to compensate for the loss of eligibility for promotion to grades AD 13 or AD 14, as laid down by the EU legislature, by means of internal measures designed to create more head of unit or equivalent or adviser or equivalent posts, because such a measure would cause the appointing authority to disregard the legislature’s intention by reducing the desired impact of the measures adopted in the context of that reform.81It is clear from Regulation No 1023/2013 that the EU legislature sought to put an end to the possibility provided for under the 2004 Staff Regulations that officials may be promoted inexorably to the highest grades without having to establish a link between their responsibilities and the grade held, which may have resulted in officials in the administrators’ function group being appointed to grades AD 13 or AD 14 without necessarily undertaking high-level or additional responsibilities.82Furthermore, the appointing authority could not classify the applicants in the types of post head of unit or equivalent or adviser or equivalent. On 31 December 2013, they were not performing duties corresponding to those types of post with the result that, since they had not submitted a request for assignment by way of derogation under Article 30(3) of Annex XIII to the new Staff Regulations, it had to assign them, respectively, to the types of post administrator or administrator in transition pursuant to Article 30(2) of Annex XIII to the new Staff Regulations (see, to that effect, order of 16 December 2015, Bärwinkel v Council, F‑118/14, EU:F:2015:154, paragraph 56).83Consequently, despite the applicants’ reported difficulties concerning their now more limited prospects of advancing to a type of post creating an entitlement to promotion to grades AD 13 or AD 14 in the light of the more stringent and selective rules regarding access to those types of post, it was not for the appointing authority to invoke the principle of sound administration or the duty to have regard for the welfare of officials as a reason for not applying the new provisions of the Staff Regulations.84It follows that the third part of the first plea in law must be rejected as unfounded.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The fourth part of the first plea in law, relating to the infringement of acquired rights</HT></TXT></NP></TI>85In support of the fourth part of the first plea in law, the applicants claim that, by blocking any possibility of promotion to grades AD 13 or AD 14 under the promotion procedure provided for in Article 45 of the Staff Regulations, the EU legislature infringed their acquired rights to have their relative merits compared to those of all grade AD 12 or AD 13 officials respectively.86In that regard, it is sufficient to point out that where, as in the present case, officials had, until the date on which the new Staff Regulations entered into force, been eligible for promotion subject to a decision of the appointing authority promoting them to a higher grade which it had not yet adopted, in the present case on 1 January 2014, such officials cannot claim an acquired right to remain eligible for that promotion after that date (see, to that effect, judgments of 22 December 2008, Centeno Mediavilla and Others v Commission, C‑443/07 P, EU:C:2008:767, paragraphs 63 to 65, and of 16 July 2015, EJ and Others v Commission, F‑112/14, EU:F:2015:90, paragraph 59). In this respect, the case-law of the International Labour Organisation (ILO), which does not concern the Staff Regulations, is irrelevant (see, to that effect, judgment of 13 December 2017, Arango Jaramillo and Others v EIB, T‑482/16 RENV, EU:T:2017:901, paragraph 113).87In addition, the applicants cannot validly claim that restricting access to grades AD 13 or AD 14 by means of promotion under Article 45 of the new Staff Regulations only for individuals selected for the post of head of unit or equivalent or adviser or equivalent following the procedure provided for in Article 4 and Article 29(1) of the Staff Regulations manifestly undermines the fundamental conditions of employment which are such as to determine [their] entry into and remaining in [the service of] the institutions of the European Union.88Under the new Staff Regulations, grade AD 12 or AD 13 officials, such as the applicants, are not excluded from access to the higher grades AD 13 or AD 14, but must, in order to attain such grades, demonstrate the qualities required by the appointing authority as responding to the high level of responsibilities expected from the holders of head of unit or equivalent or adviser or equivalent posts. It is not therefore a question of their careers being blocked but, as argued by the Council, a change in the procedure for obtaining a promotion to the highest grades available within the administrators’ function group, in this case by being selected for a new post accompanied by genuine high-level responsibilities justifying the associated high level of remuneration. Accordingly, it is still open for the applicants to participate in a selection procedure under Article 4 and Article 29 of the Staff Regulations in order to fill those types of post, thus making them eligible for promotion to a higher grade (see, to that effect, judgment of 28 April 2017, HN v Commission, T‑588/16, not published, EU:T:2017:292, paragraph 86). This is, moreover, what the majority of the applicants did which led to half of them being appointed to an expert post making them eligible for promotion to the higher grades AD 13 and AD 14.89For the sake of completeness, it should be noted that, in any event, the EU legislature provided, under Article 30(5) to (9) of Annex XIII to the new Staff Regulations, for an increase, subject to certain conditions, in basic salary for officials in grade AD 12 or AD 13, such as the applicants, and, moreover, that, pursuant to Article 30(10) and (11), if they are subsequently appointed head of unit, that increase in basic salary would be kept or they could be appointed to a higher step.90In the light of the foregoing, the fourth part of the first plea in law must be rejected.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The fifth part of the first plea in law, relating to the infringement of the rates provided for in Article 9 of Annex XIII and Section B of Annex I to the new Staff Regulations</HT></TXT></NP></TI>91By the fifth part of the first plea in law, the applicants claim that the new provisions of the Staff Regulations infringe the rules and principles relating to promotion rates, as provided for in Section B of Annex I to the new Staff Regulations and in Article 9 of Annex XIII to the new Staff Regulations, since they can no longer benefit from those rates or therefore expect a promotion to a higher grade.92In that regard, it must be stated that that argument cannot be upheld. It is with a view to ensuring greater correlation between grades AD 13 or AD 14 and the level of responsibilities of officials in those grades that the EU legislature ruled out access to those grades only through the promotion procedure provided for in Article 45 of the Staff Regulations which, previously, provided, to some extent automatically, that a certain number of administrators in grade AD 12 or AD 13 would be promoted to grades AD 13 or AD 14 every year without necessarily having to carry high-level or additional responsibilities.93It was therefore logical for the EU legislature to provide that, as a result, the number of head of unit or equivalent or adviser or equivalent posts would not be precisely determined, under the new Staff Regulations, in accordance with the rates applicable in the context of the promotion procedure. Indeed, the measure adopted in the context of the reform for the Staff regulations sought to ensure that the appointing authority would determine that number – which is, moreover, limited – in accordance with its genuine need for high-level personnel to be selected for those types of posts and no longer automatically.94In addition, in so far as the fact that the application of the promotion procedure, provided for in Article 45 of the Staff Regulations, which is excluded for the purposes of promotion to grades AD 13 or AD 14, is not contrary to the principle of equal treatment, it is not necessary, in the present case, to consider whether the mechanisms normally applicable under the promotion procedure should have been extended to the procedure provided for in Article 4 and Article 29(1) of the Staff Regulations.95On the one hand, limiting the number of posts at grade AD 13 and AD 14 to officials carrying high level responsibilities, in particular by removing such posts from the promotion procedure alone, is, moreover, an inherent objective of the reform of the Staff Regulations.96On the other, it is for the appointing authority to determine the number of head of unit or equivalent or adviser or equivalent posts it needs, the desired skills profile to fill those posts and, in addition, to obtain authorisation from the budgetary authority to create such posts. If the EU legislature had decided to require the appointing authority to create a given number of that type of post annually in order to guarantee the possibility of promotion for officials in grades AD 12 or AD 13 such as the applicants, that would have had the effect of indirectly re-establishing the promotion procedure which, in its view, failed to ensure that promotion to the highest grades – grades AD 13 and AD 14 – was subject to personal dedication, improvement of skills and competences and the performance of high-level or additional responsibilities.97Those considerations apply a fortiori to the rates provided for in Section B of Annex I to the Staff Regulations which, as the Commission rightly argues, were, in any event, intended to be applied only until 30 April 2011.98In the light of the foregoing, the fifth part of the first plea in law must be rejected.<TI><NP><NO.P>–</NO.P><TXT><HT TYPE="ITALIC">The sixth part of the first plea in law, relating to the infringement of the <QUOT.START CODE="2018" ID="QS0115" REF.END="QE0115"/>pact<QUOT.END REF.START="QS0115" CODE="2019" ID="QE0115"/> concluded between the trade union and staff associations and the Council at the time of the adoption of the previous reform of the Staff Regulations</HT></TXT></NP></TI>99Under the sixth part of the first plea in law, the applicants claim that, by adopting Regulation No 1023/2013, the EU legislature and the Commission infringed Article 10 of the Staff Regulations, which provides for consultation of the Staff Regulations Committee on all proposals to revise the Staff Regulations. That committee would certainly have been consulted on the initial Commission proposal. However, it did not contain a proposal on blocking the possibility of promotion for administrators in grades AD 12 and AD 13 because that proposal was added only at the suggestion of the Parliament in a resolution of 2 July 2013. Given the significance of the amendment made to the initial Commission proposal, the Staff Regulations Committee should have been consulted again, which was not the case.100In addition, the EU legislature and the Commission infringed the agreement concluded between the Council and the trade union and staff associations (OSPs) in the context of the previous reform of the Staff Regulations of 2004 and, more generally, failed in their obligation to liaise with the OSPs and, in particular, to consult meaningfully with them by providing the relevant information. So far as concerns, in particular, blocking any possibility of promotion for grade AD 12 or AD 13 administrators, no dialogue had been initiated and, in short, the OSPs were not at all or were badly informed of the planned modifications to the Staff Regulations. The applicants conclude that Articles 27 and 28 of the Charter of Fundamental Rights have been infringed.101In that regard, the Court has previously held that, although the Commission certainly exercised its power of legislative initiative by submitting the proposal to revise the Staff Regulations to the Parliament and to the Council on 13 December 2011, it did not, however, exercise that power to amend that proposal. Even if the Commission had participated in the trialogue negotiations held during the ordinary legislative procedure in question, the fact that the trialogue negotiations held at the first reading stage in Parliament resulted, with the participation of the Commission, in a compromise between the Parliament and the Council to amend the proposal to revise the Staff Regulations cannot constitute an amendment to that proposal by the Commission itself, within the meaning of the case-law which follows from the judgment of 11 July 2007 in Centeno Mediavilla and Others v Commission (T‑58/05, EU:T:2007:218). Moreover, the adoption at first reading by the Parliament of a text amending the proposal to revise the Staff Regulations also cannot be regarded as an amendment by the Commission itself of its initial proposal (judgment of 15 September 2016, U4U and Others v Parliament and Council, T‑17/14, not published, EU:T:2016:489, paragraphs 136 to 139).102Accordingly, the Commission was not required to consult the Staff Regulations Committee again under Article 10 of the Staff Regulations, neither after the conclusion of the trialogue negotiations held at the first reading stage in Parliament, nor after the adoption of its proposal at first reading by the Parliament (judgment of 15 September 2016,U4U and Others v Parliament and Council, T‑17/14, not published, EU:T:2016:489, paragraph 140).103In addition, the agreement concluded between the Council and the OSPs, in the context of the adoption of the reform leading to the 2004 Staff Regulations, relied on by the applicants, was concerned only with that reform and that, therefore, the subsequent adoption of Regulation No 1023/2013 was not such as to adversely affect that agreement since allowing such reasoning would limit the competence conferred on the EU legislature by Article 336 TFEU (see, to that effect, judgment of 16 November 2017, USFSPEI v Parliament and Council, T‑75/14, EU:T:2017:813, paragraphs 86 to 89).104As to whether the OSPs had been sufficiently informed and consulted during the procedure for the adoption of the new Staff Regulations, including in the light of the Articles 27 and 28 of the Charter of Fundamental Rights, the Court has already ruled in great detail on that matter by responding in full to the complaints raised in that regard by several OSPs in the judgments of 15 September 2016, U4U and Others v Parliament and Council (T‑17/14, not published, EU:T:2016:489, paragraphs 120 to 174) and of 16 November 2017, USFSPEI v Parliament and Council (T‑75/14, EU:T:2017:813, paragraphs 96 to 124).105In the absence of a substantively new argument in relation to those put forward in detail and substantiated by the OSPs themselves in the cases giving rise to the judgments referred to in paragraph 104 above, it is necessary, for the same reasons as those set out in those two judgments pending which the present case had been suspended, to reject the sixth part of the first plea in law.106In the light of the rejection of its different parts, the first plea in law must be rejected in its entirety.<TI><P><HT TYPE="ITALIC">The second plea in law, alleging infringement of Article 45 of the new Staff Regulations and manifest error of assessment</HT></P></TI>107In support of the second plea in law raised in the alternative, the applicants allege infringement of Article 45 of the Staff Regulations and manifest error of assessment directed, in essence, against recital 19 of Regulation No 1023/2013 adopted by the EU legislature. In essence, they claim that, in so far as the core of the promotion scheme provided for under Article 45 had not been modified by that regulation, the EU legislature was required to respect the principles that underpin that scheme and could not therefore exclude the applicants from any comparative evaluation of their merits with a view to their promotion to a higher grade. Accordingly, recital 19 of Regulation No 1023/2013 is in conflict with Article 45 of the Staff Regulations.108The Commission, supported by the Parliament and the Council, contends that the second plea in law should be rejected as unfounded.109In that regard, it should be borne in mind that the EU legislature may amend the Staff Regulations at any time by means of regulations adopted pursuant to Article 336 TFEU (see order of 23 April 2015, Bensai v Commission, F‑131/14, EU:F:2015:34, paragraph 40 and the case-law cited). However, when it decides to make such amendments, it cannot be criticised for failing to take account of the Staff Regulations since it is the author of them, including any modifications thereto, and the Staff Regulations are not therefore binding on it unlike higher-ranking texts such as treaties.110Moreover and in any event, assuming that the second plea in law can be regarded as a plea of illegality raised against recital 19 of Regulation No 1023/2013 and that it is admissible, even though, according to the case-law, a recital cannot, by itself, be the subject of an action for annulment (order of 17 September 2014, Afepadi and Others v Commission, T‑354/12, not published, EU:T:2014:798, paragraph 32), it is clear that, by adopting that recital, as well as the amendment to Article 45 of the Staff Regulations, the EU legislature clearly intended to amend the promotion procedure under Article 45 of the 2004 Staff Regulations by precluding its application to administrators in grades AD 12 and AD 13 who do not perform the duties of a head of unit or equivalent or adviser or equivalent, posts which must henceforth be filled following an appointment procedure under Article 4 and Article 29(1) of the Staff Regulations. In that regard, contrary to what the applicants claim, the legislature clearly added a sentence to the wording of Article 45 of the new Staff Regulations in order to preclude its application to situations such as those of the applicants in which officials have attained the highest possible grade for the type of post they occupy.111The second plea in law must therefore be rejected.<TI><P><HT TYPE="ITALIC">The third plea in law, alleging infringement of the obligation to state reasons</HT></P></TI>112By its third plea in law, raised in the alternative, the applicants criticise the Commission for failing to satisfy its obligation to state reasons by not explaining further, in addition to the explanations set out by the EU legislature in recitals 17 to 19 of Regulation No 1023/2013, the reasons why they were not considered to be exercising the highest level of responsibilities and can henceforth be promoted to grades AD 13 or AD 14 only if they are appointed, under the appointment procedure provided for in Article 4 and Article 29(1) of the Staff Regulations, to a head of unit or equivalent or adviser or equivalent post.113The Commission, supported by the Parliament and the Council, contends that the third plea in law should be rejected as unfounded.114In that regard, it should be borne in mind that the purpose of the obligation to state reasons laid down in the second paragraph of Article 25 of the Staff Regulations, which merely reproduces the general obligation set out in Article 296 TFEU, is, first, to provide the person concerned with sufficient information to make it possible to determine whether the act is well founded or whether it is vitiated by an error which may permit its validity to be contested before the EU Courts and, second, to enable those Courts to review the lawfulness of the act. The statement of reasons must therefore in principle be notified to the person concerned at the same time as the decision adversely affecting him or her, for failure to state the reasons cannot be remedied by the fact that the person concerned learns the reasons for the act during the proceedings before the EU Courts (judgments of 26 November 1981, Michel v Parliament, 195/80, EU:C:1981:284, paragraph 22, and of 28 February 2008, Neirinck v Commission, C‑17/07 P, EU:C:2008:134, paragraph 50).115However, those principles must be implemented in the light of the evolving nature of the pre-litigation procedure, under which the administrative complaint and its rejection, whether express or implied, constitute an integral part of a complex procedure, in so far as the drawing up of the act laying down the institution’s definitive position is completed only after the adoption of the appointing authority’s response to the complaint (see, to that effect, judgment of 21 May 2014, Mocová v Commission, T‑347/12 P, EU:T:2014:268, paragraphs 33, 34 and 45).116In that context, the Court has observed that the additional statement of reasons, at the stage of the decision rejecting the complaint, was consistent with the purpose of Article 90(2) of the Staff Regulations, on which the reasoned decision rejecting the complaint was based. That provision necessarily implies that the authority called upon to rule on the complaint is not bound solely by the reasons for the decision that is the subject of the complaint, which may be inadequate or non-existent (judgments of 7 July 2011, Longinidis v Cedefop, T‑283/08 P, EU:T:2011:338, paragraph 72, and of 21 May 2014, Mocová v Commission, T‑347/12 P, EU:T:2014:268, paragraph 35).117In the present case, the contested decisions were not accompanied by a specific statement of reasons from the appointing authority. In essence, the appointing authority merely implemented the provisions of the new Staff Regulations which took effect on 1 January 2014 and involved, in the case of the applicants, assigning them to the posts administrator or administrator in transition as indicated by a reference made in the applicants’ individual files in SysPer 2 with effect from that date.118However, in response to the applicants’ complaints, the appointing authority explained that its approach had been to implement the provisions of the Staff Regulations decided on by the EU legislature, without having any discretion in that regard, and it provided them with a detailed explanation of the challenges and arrangements for the implementation of the reform of the Staff Regulations introduced in 2014. Such explanations from the appointing authority are sufficient, in the light of its obligation to state reasons provided for in Article 25(2) of the Staff Regulations, as the author of the contested decisions adopted in the context of circumscribed powers.119In so far as, by the present plea, the applicants seek to criticise the EU legislature for failing to satisfy the obligation to state reasons set out in Article 296 TFEU, it has already been held, in specific connection with recitals 17 to 19 of Regulation No 1023/2013, that the statement of reasons on which the amendments to Article 45, and Annexes I and XIII to the new Staff Regulations, relating to the career structure of officials are based, clearly and unequivocally indicate the position of the Parliament and of the Council, thus making it possible for the applicants to know the justifications for the measure taken and for the Court to exercise its power of review (see, to that effect, judgment of 15 September 2016, U4U and Others v Parliament and Council, T‑17/14, not published, EU:T:2016:489, paragraphs 182 and 183).120Moreover, it is clear from the new Staff Regulations that it is only if the appointing authority decides, in accordance with its needs, to create head of unit or equivalent or adviser or equivalent posts, that, whilst they are to be appointed under Article 4 and Article 29 of the Staff Regulations, administrators or administrators in transition in grades AD 12 or AD 13, such as the applicants, will be eligible for promotion in the context of the procedure provided for in Article 45 of the new Staff Regulations. In addition, it is also clear from the decisions rejecting the complaints that the appointing authority has not acknowledged that the applicants exercised responsibilities as significant as those normally conferred on heads of unit or equivalent or advisers or equivalent.121It is apparent from the foregoing considerations that the third plea in law must be rejected. The action must therefore be rejected in its entirety.<TI><P><HT TYPE="BOLD">Costs</HT></P></TI>122Under Article 134(1) of the Rules of Procedure, the unsuccessful party is to be ordered to pay the costs if they have been applied for in the successful party’s pleadings.123As the applicants have been unsuccessful, they must be ordered to pay the costs, in accordance with the form of order sought by the Commission.124In accordance with Article 138(1) of the Rules of Procedure, the institutions which have intervened in the proceedings are to bear their own costs.125The Parliament and the Council must therefore bear their own costs.

On those grounds,

THE GENERAL COURT (First Chamber)

hereby:

1.Dismisses the action;2.Orders FZ and the other officials of the European Union whose names appear in the annex to pay the costs;3.Orders the European Parliament and the Council of the European Union to bear their own costs.
