In that regard, it need only be stated that the question whether partial annulment would alter the substance of the contested measure is an objective criterion, and not a subjective criterion linked to the political intention of the authority which adopted the measure at issue (see Case C-239/01Germany v Commission [2003] ECR I-10333, paragraph 37, and Case C-244/03France v Parliament and Council, cited above, paragraph 14).
