57It is only quite exceptionally that the Court may, in application of the general principle of legal certainty inherent in the EU legal order, be moved to restrict the opportunity, open to any person concerned, of relying on a provision which it has interpreted with a view to calling into question legal relationships established in good faith. Two essential criteria must be fulfilled before such a limitation can be imposed: those concerned must have acted in good faith and there must be a risk of serious difficulties (judgment of 24 November 2020, Openbaar Ministerie (Forgery of documents), C‑510/19, EU:C:2020:953, paragraph 74 and the case-law cited).
