29In order to comply with a judgment annulling a measure and to implement it fully, the institution is required, according to settled case-law, to have regard not only to the operative part of the judgment but also to the grounds which led to the judgment and constitute its essential basis, in so far as they are necessary to determine the exact meaning of what is stated in the operative part. It is those grounds which, on the one hand, identify the precise provision held to be illegal and, on the other, indicate the specific reasons which underlie the finding of illegality contained in the operative part and which the institution concerned must take into account when replacing the annulled measure (Joined Cases 97/86, 99/86, 193/86 and 215/86 Asteris and Others v Commission [1988] ECR 2181, paragraph 27, and Case C-458/98 P Industrie des poudres sphériques v Council [2000] ECR I-8147, paragraph 81).
