The requirement for a hand-written signature of the applicant’s representative ensures, with the aim of legal certainty, the authenticity of the application and excludes the risk that it is not the work of the lawyer or counsel authorised for that purpose. Thus, the latter, as an officer of the court, fulfils the essential role conferred on him by the Statute of the Court of Justice and the Rules of Procedure of the Civil Service Tribunal by enabling, through his ministry, the applicant to have access to the Tribunal. That requirement must therefore be regarded as an essential procedural requirement and be strictly applicable, so that the failure to comply with it renders the action inadmissible.

It follows from the third paragraph of Article 19 and the first paragraph of Article 21 of the Statute of the Court of Justice that every applicant must be represented by a person authorised for that purpose and that, consequently, an action may be validly brought before the Courts of the European Union only if that person signs the application. Under Article 7(1) of Annex I to the Statute of the Court of Justice, those provisions are also applicable to the procedure before the Civil Service Tribunal. No derogation or exception to that obligation is provided for in the Statute of the Court of Justice or the Rules of Procedure of the Civil Service Tribunal.

In the context of European Union civil service judicial proceedings, for the purpose of the lodging of the original of every procedural document within the prescribed period, Article 34 of the Rules of Procedure of the Civil Service Tribunal does not allow the representative of the party concerned to place two separate, hand-written signatures, even if they are authentic, one on the document sent by fax to the Registry of the Tribunal and the other on the original that will be sent by post or delivered by hand to the Registry.

In those circumstances, if it is apparent that the original of the document which is physically lodged with the Registry within 10 days of a copy thereof being sent to the Civil Service Tribunal by fax does not bear the same signature as that on the document sent by fax, it must be held that two separate procedural documents arrived at the Registry of the Tribunal, each bearing a distinct signature, even if the signature was placed on the relevant document by the same person. Since the lodging of the text sent by fax does not satisfy the conditions of legal certainty required by Article 34 of the Rules of Procedure of the Civil Service Tribunal, the date on which the copy was sent by fax cannot be taken into account for the purpose of compliance with the period prescribed for bringing an action.

Furthermore, the period for bringing an action is laid down in Article 91(3) of the Staff Regulations, from which the Rules of Procedure of the Civil Service Tribunal cannot derogate. Consequently, the original of the application must be drawn up no later than the end of that period. From that point of view, sending a document by fax is not just a mode of transmission, but also serves as proof that the original of the action received at the Registry of the Tribunal after that period has expired had already been drawn up within the period prescribed for bringing an action.
