33According to settled case-law of the Court, in the absence of European Union rules in this area, it is for the domestic legal system of 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 litigants derive from European Union law, provided, first, that such rules are not less favourable than those governing similar domestic actions (principle of equivalence) and, secondly, that they do not render virtually impossible or excessively difficult the exercise of rights conferred by European Union law (principle of effectiveness) (see, inter alia, Case C-262/09 Meilicke and Others [2011] ECR I-5669, paragraph 55, and Case C‑603/10 Pelati [2012] ECR, paragraph 23).
