46The Court has consistently held that, in the absence of EU rules governing the matter, it is for each Member State, in accordance with the principle of the procedural autonomy of the Member States, to lay down the detailed rules of administrative and judicial procedures governing actions for safeguarding rights which individuals derive from EU law. Those detailed procedural rules must, however, be no less favourable than those governing similar domestic actions (principle of equivalence) and must not render practically impossible or excessively difficult the exercise of rights conferred by EU law (principle of effectiveness) (judgments in Club Hotel Loutraki and Others, C‑145/08 and C‑149/08, EU:C:2010:247, paragraph 74, and eVigilo, C‑538/13, EU:C:2015:166, paragraph 39).
