Judgment_paragraph 72 · Criminal proceedings against Nikolay Kolev and Others (C-612/15)

72In accordance with the Court’s settled case-law, the reasonableness of the length of proceedings cannot be determined by reference to a precise maximum limit determined in an abstract manner. It must be assessed in the light of all of the circumstances specific to each case, the importance of the case for the person concerned, its complexity or the conduct of the competent authorities and the parties, where such complexity or delaying tactics on the part of the defence may be deemed to justify a period that is prima facie too long (see, to that effect, judgments of 26 November 2013, Groupe Gascogne v Commission, C‑58/12 P, EU:C:2013:770, paragraphs 85 and 86, and of 14 June 2016, Marchiani v Parliament, C‑566/14 P, EU:C:2016:437, paragraphs 99 and 100).
