46As regards the principle of legal certainty, it should be borne in mind that that principle requires that legal rules be clear and precise and that their application be foreseeable by those subject to them, so that those concerned may know precisely the extent of the obligations which the legislation in question imposes on them and that they may be able to ascertain unequivocally what their rights and obligations are and take steps accordingly (see, to that effect, judgments of 25 July 2018, Teglgaard and Fløjstrupgård, C‑239/17, EU:C:2018:597, paragraph 52 and the case-law cited, and of 16 February 2022, Poland v Parliament and Council, C‑157/21, EU:C:2022:98, paragraph 319).
