36It also held that, in order to comply with principles of legal certainty and the protection of legitimate expectations, the basic rules of EU law must, in principle, be interpreted as applying only to situations existing after their entry into force (see, to that effect, judgment of 24 September 2002, Falck and Acciaierie di Bolzano v Commission, C‑74/00 P and C‑75/00 P, EU:C:2002:524, paragraph 119). Thus, in general, the principle of legal certainty precludes an EU measure from taking effect from a point in time before its publication or its notification, as the case may be, since the Court has ruled that it may exceptionally be otherwise, where the purpose to be achieved so demands and where the legitimate expectations of those concerned are duly respected (see, to that effect, judgments of 30 September 1982, Amylum v Council, 108/81, EU:C:1982:322, paragraph 4; of 26 April 2005, ‘Goed Wonen’, C‑376/02, EU:C:2005:251, paragraph 33 and the case law cited; and of 28 November 2006, Parliament v Council, C‑413/04, EU:C:2006:741, paragraph 75 and the case-law cited).
