59The Commission refers to the case which gave rise to the judgment of the Court of Justice in Denkavit v Commission (Case 14/78 [1978] ECR 2497), in which the applicant complained that the Commission had waited 21 months before taking measures, in circumstances comparable to those in this case. It points out that, in the judgment in that case (paragraph 20), the Court of Justice held that the Commission could not be blamed for having waited until it was fully informed before adopting a decision on a matter as complex as the presence in feeding-stuffs of substances which might prove to be undesirable from the point of view of human or animal health.
