158It follows from the settled case-law of the Court that the principle of legal certainty requires, on the one hand, that the rules of law be clear and precise and, on the other, that their application be foreseeable for those subject to the law, in particular, where they may have adverse consequences. That principle requires, inter alia, that legislation must enable those concerned to know precisely the extent of the obligations imposed on them, and those persons must be able to ascertain unequivocally their rights and obligations and take steps accordingly (judgment of 16 February 2022, Hungary v Parliament and Council, C‑156/21, EU:C:2022:97, paragraph 223 and the case-law cited).
