135Thus, where the Director of SatCen does not reply to a request for assistance for the purposes of Article 2(6) of the SatCen Staff Regulations, within the two-month period laid down in Article 28(1) of those staff regulations, it may be considered that there has been an implied decision rejecting that request for assistance. In that case, it must be presumed that the Director of SatCen considered that the evidence produced in support of the request for assistance did not constitute some evidence of the reality of the alleged facts triggering the duty of assistance, which may result in the opening of an administrative investigation where the alleged facts are classified as psychological harassment (see, by analogy, judgments of 25 October 2007, Lo Giudice v Commission, T‑154/05, EU:T:2007:322, paragraph 41, and of 24 April 2017, HF v Parliament, T‑570/16, EU:T:2017:283, paragraphs 53 to 57).
