Judgment_paragraph 83 · WS and Others v European Border and Coast Guard Agency (C-679/23 P)

83According to 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, 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 plea in law 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, paragraph 38 and the case-law cited).
