Judgment_paragraph 93 · Caisse de retraite du personnel navigant professionnel de l'aéronautique civile (CRPNPAC) v Vueling Airlines SA v Vueling Airlines SA and Jean-Luc Poignant (C-370/17, C-37/18)

93In that regard, the Court has already held that every case in which the question arises as to whether a national procedural provision makes the application of EU law impossible or excessively difficult must be analysed by reference to the role of that provision in the procedure, its operation and its particular features, viewed as a whole, before the various national bodies. For those purposes, account must be taken, where appropriate, of the basic principles of the domestic judicial system, such as protection of the rights of the defence, the principle of legal certainty and the proper conduct of procedure (judgment of 3 September 2009, Fallimento Olimpiclub, C‑2/08, EU:C:2009:506, paragraph 27 and the case-law cited).
