Judgment_paragraph 42 · Ziegler SA v European Commission (C-439/11 P)

42Second, according to the Court’s settled case-law, for a request for substitution of grounds to be admissible, the appellant must have an interest in bringing proceedings, in so far as the request must be capable, if successful, of procuring an advantage to the party making it. That may be the case where the request for substitution of grounds amounts to a defence to one of the applicant’s pleas (see, to that effect, Joined Cases C-501/06 P, C-513/06 P, C-515/06 P and C-519/06 P GlaxoSmithKline Services and Others v Commission [2009] ECR I-9291, paragraph 23, and the judgment of 21 December 2011 in Case C-329/09 P Iride v Commission, paragraphs 48 to 51).
