Judgment_paragraph 55 · Vicente v Delia (C-335/21)

55As regards the principle of effectiveness, which alone is the subject of the referring court’s questions, it is the Court’s settled case‑law that every case in which the question arises as to whether a national procedural provision makes the application of European Union law impossible or excessively difficult must be analysed by reference to the role of that provision in the procedure, its progress and its special features, viewed as a whole, before the various national bodies (judgment of 14 March 2013, Aziz, C‑415/11, EU:C:2013:164, paragraph 53 and the case-law cited).
