31According to Article 176 of the Treaty, the institution whose act has been declared void is required to take the measures necessary to comply with the judgment of the Court. As the Court held in its judgment in Joined Case 97/86, 193/86, 99/86 and 215/86 Asieris and Others v Commission [1988] ECR 2181, paragraph 27, in order to comply with the judgment and to implement it fully, the institution is required 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. The procedure for replacing such a measure may thus be resumed at the very point at which the illegality occurred (see the judgment in Case 34/86 Council v Parliament [1986] ECR 2155, paragraph 47).
