104With regard to the appropriate conclusions to be drawn from any annulment, it must be recalled that, although, in accordance with settled case-law, it is not the function of the European Union judicature to issue directions to the EU institutions or to substitute itself for those institutions when exercising its powers of review, it is however for the institution concerned, under Article 266 TFEU, to adopt the measures required to give effect to a judgment delivered in an action for annulment (see judgment of 30 May 2013, Omnis Group v Commission, T‑74/11, not published, EU:T:2013:283, paragraph 26 and the case-law cited).
