Hence the idea of allowing the court, when it annuls an administrative decision, to include in its judgment specific orders as to whether and when the annulment will produce effects and, if so, which persons might be in a special position. Such a discretion has been used for a long time by both European courts. The European Court of Human Right’ judgment in Marckx v. Belgium (1979-80) 2 E.H.R.R. 330, is an apt illustration. As for the ECJ, it construed broadly the second paragraph of Art. 231 EC (formerly Art.174) according to which: "In the case of a regulation, however, the Court of Justice shall, if it considers this necessary, state which of the effects of the regulation which it has declared void shall be considered as definitive". This derogation to the ex tunc effect has been applied in cases relating not only to regulations, but also to preliminary rulings concerning interpretation (Case C-43/75 Defrenne v. Sabena (1976 E.C.R. 455; Case C-61/79 Denkjavit Italiana (1980 E.C.R. 1205; Case C-4/79 Societe Cooperative Providence agricole de la Champagne (1980 ECR 2823; Case C-109/79 Maiseies de Beauce (1980 E.C.R. 2882; Case-145/79 Societe Roquette Freres (1980 E.C.R. 2917), directives (Case C-295/90 European Parliament v. Council (1992 E.C.R. I4193) and decisions (Case C-22/96) European Parliament v Council (1998 E.C.R. I-3231). The ECJ held that the use of such a power was justified in order to take into account "imperious considerations of legal certainty relating to all interests at stake, public and private". In doing so, however, the Court’s decisions could harm the rights of the very petitioners who wanted the Court to arrive at the decision it took. Hence the dissenting decisions of several national higher courts, such as the Italian Constitutional Court (April 21, 1989, Fragd) and the Conseil d’Etat (June 28, 1985, Office national interprofessionnel des cereales o Societe Maiseries de Beauce, concl. Genevois, RTDE, 1986, 145; July 26, 1985; Office national interprofessionnel des cereales, p.233, concl. Genevois AJDA, 1985; June 13, 1986, Office national interprofessionnel des cereales, concl. Bonichot, RTDE 1986, 533). This is why the ECJ took some precautions to protect the rights of persons who had previously brought an action or an equivalent claim. Some ECJ judgments led to the inclusion of special clauses into the EC Treaty, as shown by the Maastricht Treaty Protocol 2 (the "Barber Declaration") following the ECJ’s judgment in Case C-262/88 Barber v. Guardian Royal Exchange Assurance Group (1991 (1) Q.B. 344). This Protocol limits the effects ratione temporis (before May 17, 1990) of Article 141 EC. The ECJ has been explicit on the considerations it takes into account to use such powers. They relate, on the whole, to legal certainty lato sensu, i.e. to the concrete effects of its decision on existing legal situations, and the desirability of avoiding the creation of a legal void. Many European constitutional courts have a similar power.
