En konstatering af, at der under omstændigheder som de i hovedsagen foreliggende er tale om en støtte, som er retsstridig, fordi den ikke blev godkendt af Kommissionen, da den blev givet, og i givet fald forskelsbehandling af producenter som omhandlet i EKSF-traktatens artikel 4, litra b), som består i. at nogle producenter skal betale afgifter, mens andre er fritaget derfor, kan ikke føre til, at de producenter, som har været pålagt disse afgifter, er fritaget for dem med tilbagevirkende gyldighed.
In a situation such as that in the main proceedings, the finding of the existence of unlawful aid, on the ground that it was not authorised by the Commission at the time when it was granted, and, as the case may be, of discrimination between producers within the meaning of Article 4(b) of the Treaty, in that some producers were subject to the payment of royalties whereas others were exempt, cannot lead to producers who have been made subject to those royalties being retrospectively exonerated from them.
