84Next, it likewise follows from established case-law that, in the context of a claim for damages brought by an official or other staff member, in order for the institution to incur liability, three conditions must be satisfied, concerning the unlawfulness of the conduct alleged against it, the reality of the harm suffered and the existence of a causal link between the act and the harm allegedly suffered. The three conditions giving rise to the institution’s liability are cumulative, which means that if one of them is not met, the institution does not incur liability. Furthermore, the EU Courts are not required to examine those conditions in any particular order (see order of 11 June 2020, Vanhoudt and Others v EIB, T‑294/19, not published, EU:T:2020:264, paragraph 70 and the case-law cited).
