Other parties to the proceedings: European Commission and Council of the European Union

Forms of order sought

The appellants claim that the Tribunal should:

— Set aside the judgment of the Civil Service Tribunal of the European Union (Third Chamber) of 21 March 2013 in Case F-111/11 Chris Van der Aat and Others v European Commission;

— Giving judgment itself,

— Declare illegal Article 1 of Annex XI to the Staff Regulations and the methodological manual referred to in Annex I to Regulation No 1445/2007 of 11 December 2007;

— Declare illegal Article 3 of Council Regulation (EU) No 1239/2010 of 20 December 2010 fixing the correction coefficient for the calculation of the remuneration of staff assigned to Varese at 92.3;

— Annul the decisions establishing the applicants’ salary statements drawn up on the basis of the correction coefficient for the town of Varese set out in Council Regulation (EC) No 1239/2010 of 20 December 2010 applicable with effect from 1 July 2010;

— Order the Commission to pay the costs of both sets of proceedings.

Pleas in law and main arguments

In support of the appeal, the appellants put forward the following grounds of appeal.

1. First ground of appeal, alleging that the Civil Service Tribunal, when it examined the plea in law alleging breach of the obligation to state reasons, erred in law in holding that the Commission could confine itself to referring to Regulation No 1239/2010 (1) to substantiate its decision to apply a correction coefficient reduced by 4.8 percentage points to 92.3 % for the calculation of the appellants’ salaries in Varese, even though the Commission played a decisive role in the laying down of those weightings by assessing the statistical data and the methods used to set those coefficients. Thus, the Commission did not merely apply an act of general application without exercising discretion (paragraphs 27 and 28 of the judgment under appeal).

2. Second ground of appeal, alleging that the Civil Service Tribunal, when it examined the plea in law alleging breach of the right of access to documents, erred in law in holding that the Commission had no obligation to communicate the information requested by the staff representatives, members of the ‘Technical Group on Salaries’ (TGS), then by the appellants, in response to their claim. Inter alia, the appellants submit that: — in so doing, the Civil Service Tribunal misconstrued, inter alia, the nature of the contested acts, the complex procedure by which the correction coefficients are set which justifies the creation of a TGS, the very existence of that TGS and the subject-matter of the pre-litigation procedure; — the procedure recommended by the Civil Service Tribunal, which requires that the parties concerned must submit a request for access to documents outside the TGS and apply the remedies available to them, breaches the right to an effective remedy given the period in which the access to the documents could be obtained and as the analysis of the technical data will be difficult to carry out by the hundreds of agents concerned individually; — that position further misconstrues the ‘effectiveness’ of the constitution of a TGS and the nature of the lex specialis of the statutory remedies established to contest correction coefficients affecting remuneration.

3. Third ground of appeal, alleging that the Civil Service Tribunal, when it examined the plea in law alleging a manifest error of assessment, erred in law: — in holding that the disparity between the cost of living in Brussels and that in Varese, on the one hand, and the reduction of the correction coefficient of Varese as established by Regulation No 1239/2010, on the other, is not enough to support a conclusion that there was a manifest error of assessment and — in requiring that the appellants submit data as relevant and precise as that which only the Commission possesses even though the case-law does not require the production of a body of evidence sufficiently probative as to reverse the burden of proof and the presumption of legality of the contested coefficient.

(1) Council Regulation (EU) No 1239/2010 adjusting with effect from 1 July 2010 the remuneration and pensions of officials and other servants of the European Union and the correction coefficients applied thereto (OJ 2010 L 338, p. 1).
