Judgment_paragraph 37 · CW v European Parliament (F-124/13)

37By virtue of the duty to provide assistance, the administration, when faced with an incident which is incompatible with the good order and tranquillity of the service, must intervene with all the necessary vigour and respond with the rapidity and solicitude required by the circumstances of the case so as to ascertain the facts and, having done so, to take the appropriate action in full knowledge of the matter. To that end, it is sufficient that the official who is seeking the protection of his institution provide prima facie evidence that the attacks of which he claims to have been the victim actually took place. When such evidence is provided, the institution concerned is then under an obligation to take the necessary measures, in particular to carry out an inquiry, with the cooperation of the complainant, to determine the facts which gave rise to the complaint (judgments in Koutchoumoff v Commission, 224/87, EU:C:1989:38, paragraphs 15 and 16; Tallarico v Parliament, T‑5/92, EU:T:1993:37, paragraph 31; Campogrande v Commission, T‑136/98, EU:T:2000:281, paragraph 42; Schochaert v Council, T‑136/03, EU:T:2004:229, paragraph 49; and Lo Giudice v Commission, EU:T:2007:322, paragraph 136).
