112In that regard, it is necessary to bear in mind the principle that amending legislation applies, unless otherwise provided, to the future consequences of situations which arose under the previous legislation (see judgments of 29 June 1999 in Butterfly Music, C‑60/98, ECR, EU:C:1999:333, paragraph 24 and the case-law cited, and 29 January 2002 Pokrzeptowicz-Meyer, C‑162/00, ECR, EU:C:2002:57, paragraph 50). Although procedural rules are generally held to apply to all disputes pending at the time when they enter into force, substantive rules must be interpreted, in order to ensure respect for the principles of legal certainty and the protection of legitimate expectations, as applying to situations existing before their entry into force only in so far as it clearly follows from their wording, objectives or general scheme that such an effect must be given to them (see judgments of 24 September 2002 in Falck and Acciaierie di Bolzano v Commission, C‑74/00 P and C‑75/00 P, ECR, EU:C:2002:524, paragraph 119 and the case-law cited, and 1 July 2009 ThyssenKrupp Stainless v Commission, T‑24/07, ECR, EU:T:2009:236, paragraph 85 and the case-law cited).
