Judgment_paragraph 115 · E.ON Energie AG v European Commission (C-89/11 P)

115As regards the failure by the General Court to order measures of inquiry, it should be borne in mind that, according to well‑established case‑law, the General Court is the sole judge of any need to supplement the information available to it concerning the cases before it. The question whether the procedural documents before it are convincing is a matter to be appraised by it alone, which, again according to well‑established case‑law, is not subject to review by the Court of Justice, unless the facts or evidence have been distorted (see Case C-119/97 P Ufex and Others v Commission [1999] ECR I-1341, paragraph 66; and Case C-315/99 P Ismeri Europa v Court of Auditors [2001] ECR I-5281, paragraph 19).
