214According to the case-law, the sanction for a breach, by an EU Court, of its obligation to adjudicate within a reasonable time must be an action for damages, not an action for annulment and for cancellation or reduction of the fine, since the former constitutes an effective remedy (see, to that effect and by analogy, judgments of 26 November 2013, Gascogne Sack Deutschland v Commission, C‑40/12 P, EU:C:2013:768, paragraph 89, and of 21 September 2017, Feralpi v Commission, C‑85/15 P, EU:C:2017:709, paragraph 54).
