58That being so, subject to any EU rules on the matter, it is, in accordance with the principle of procedural autonomy, for the national legal order of each Member State to establish procedural rules for the remedies referred to in paragraph 56 of the present judgment, on condition, however, that those rules are not – in situations governed by EU law – less favourable than in similar domestic situations (principle of equivalence) and that they do not make it impossible in practice or excessively difficult to exercise the rights conferred by EU law (principle of effectiveness) (see, to that effect, judgment of 10 March 2021, Konsul Rzeczypospolitej Polskiej w N., C‑949/19, EU:C:2021:186, paragraph 43 and the case-law cited).
