72Likewise, the Court has stated that, while Member States are still, in principle, free to determine the requirements of public policy and public security in the light of their national needs, those grounds must, in the EU context and, in particular, as derogations from a fundamental freedom enshrined in the TFEU, be interpreted strictly, so that their scope cannot be determined unilaterally by each Member State without any control by the EU institutions. Thus, public security may be relied on only if there is a genuine and sufficiently serious threat to a fundamental interest of society (see, to that effect, judgments of 18 June 2020, Commission v Hungary (Transparency of associations), C‑78/18, EU:C:2020:476, paragraph 91 and the case-law cited, and of 13 July 2023, Xella Magyarország, C‑106/22, EU:C:2023:568, paragraphs 66 and 67).
