19In its rejoinder the ESC, which refers to Article 7(1) and Article 29(1)(a) of the Staff Regulations, submits that, under the Staff Regulations, transfer is subject to rules strictly identical to those governing promotion. It follows from that which the Court has consistently held that promotions and transfers are to be considered as being ‘on a par’ (see, for example, the judgment of the Court of Justice in Case 55/70Reinarz v Commission [1971] ECR 379, paragraphs 4 and 5). Consequently, the case-law cited, according to which there is no obligation to give a statement of reasons in the event of a decision not to promote, does indeed apply even to a decision rejecting a request for a transfer. In the judgment in Case 233/85 in Bonino v Commission [1987] ECR 739, paragraph 4, the Court of Justice even applied that principle to decisions assigning an official to a new post.
