171That obligation is also incumbent on national courts before which an action against a national measure including such a consent has been brought. The detailed procedural rules applicable to such actions are a matter for the domestic legal order of each Member State, under the principle of procedural autonomy of the Member States, provided that they are not less favourable than those governing similar domestic situations (the principle of equivalence) and that they do not render impossible in practice or excessively difficult the exercise of rights conferred by the European Union legal order (the principle of effectiveness) (see, to that effect, judgment of 28 February 2012, Inter-Environnement Wallonie and Terre wallonne, C‑41/11, EU:C:2012:103, paragraph 45 and the case-law cited).
