Judgment_paragraph 74 · Club Hotel Loutraki AE and Others v Ethnico Symvoulio Radiotileorasis and Ypourgos Epikrateias and Aktor Anonymi Techniki Etaireia (Aktor ATE) v Ethnico Symvoulio Radiotileorasis (C-145/08, C-149/08)

74The Court has consistently held that, in the absence of Community rules governing the matter, it is for each Member State to designate the courts and tribunals having jurisdiction and to lay down the detailed procedural rules governing actions for safeguarding rights which individuals derive from European Union 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 European Union law (principle of effectiveness) (see, to that effect, Case C-268/06 Impact [2008] ECR I-2483, paragraphs 44 and 46 and the case-law cited).
