Judgment_paragraph 35 · NC v European Commission (T-151/16)

35In that regard, first of all, it should be recalled that, according to a generally accepted principle and save as otherwise provided, a new rule applies immediately to situations yet to arise and to the future effects of situations which arose under the old rule. On the other hand, it does not normally apply to legal situations that have arisen and become definitive under that old rule (see, to that effect, judgments of 9 December 1965, Singer, 44/65, EU:C:1965:122, p. 1200; of 15 February 1978, Bauche, 96/77, EU:C:1978:26, paragraph 48; and of 26 March 2015, Commission v Moravia Gas Storage, C‑596/13 P, EU:C:2015:203, paragraph 32). It is otherwise, subject to the principle of the non-retroactivity of legal acts, only if the new rule is accompanied by special provisions which specifically lay down its conditions of temporal application (see judgment of 7 November 2013, Gemeinde Altrip and Others, C‑72/12, EU:C:2013:712, paragraph 22 and the case-law cited).
