Judgment_paragraph 83 · European Commission v Jiangsu Seraphim Solar System Co. Ltd and Council of the European Union v Jiangsu Seraphim Solar System Co. Ltd (C-439/20 P)

83It must be borne in mind that, under Article 170(1) of the Rules of Procedure of the Court of Justice, the subject matter of the proceedings before the General Court may not be changed in the appeal. Thus, according to settled case-law, the jurisdiction of the Court of Justice in an appeal is limited to review of the findings of law on the pleas and arguments debated before the General Court. A party cannot, therefore, put forward for the first time before the Court of Justice a ground of challenge which it has not raised before the General Court since that would allow that party to bring before the Court of Justice, whose jurisdiction in appeal proceedings is limited, a wider case than that heard by the General Court (judgment of 6 October 2021, Sigma Alimentos Exterior v Commission, C‑50/19 P, EU:C:2021:792, paragraphs 37 and 38).
