53In that connection, it should be recalled that, according to settled case-law, in the absence of EU rules on the matter, it is for the national legal order of each Member State to establish procedural rules for actions intended to safeguard the rights of individuals, in accordance with the principle of procedural autonomy, on condition, however, that those rules are not, in situations covered by EU law, less favourable than those governing similar domestic situations (principle of equivalence) and that they do not make it excessively difficult or impossible in practice to exercise the rights conferred by EU law (principle of effectiveness) (see, to that effect, judgments of 13 December 2017, El Hassani, C‑403/16, EU:C:2017:960, paragraph 26, and of 15 September 2022, Uniqa Versicherungen, C‑18/21, EU:C:2022:682, paragraph 36).
