116It is necessary, moreover, to note that, in accordance with the principle of procedural autonomy, in the absence of Union law on the subject, it is for the domestic legal order of each Member State to designate the courts having jurisdiction and to lay down the detailed rules governing legal proceedings designed to safeguard the rights which individuals derive from Union law. Thus, once the conditions for State liability have been met, which is to be determined by the national courts, it is within the framework of national liability law that it is incumbent on the State to make good the consequences of the damage caused to the individual by the breach of Union law in question, provided that the conditions laid down by the national laws applicable for that purpose are not less favourable than those applicable to similar claims based on a breach of national law (principle of equivalence) and are not so adjusted as to make it impossible or excessively difficult in practice to obtain reparation (principle of effectiveness) (judgment of 4 October 2018, Kantarev, C‑571/16, EU:C:2018:807, paragraphs 122 and 123 and the case-law cited). Compliance with those two principles must be examined in the light of the role of the rules concerned in the entire procedure, the conduct of the procedure and the particularities of those rules before the various national bodies (see, in this sense, judgment of 11 September 2019, Călin, C‑676/17, EU:C:2019:700, paragraph 31 and the case-law cited).
