21According to the Court’s settled case-law, in the absence of EU rules in the field, 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 individuals derive from EU law, provided, first, that such rules are not less favourable than those governing similar domestic actions (principle of equivalence) and, second, that they do not render virtually impossible or excessively difficult the exercise of rights conferred by EU law (principle of effectiveness) (judgment of 7 June 2007, van der Weerd and Others, C‑222/05 to C‑225/05, EU:C:2007:318, paragraph 28 and the case-law cited).
