149It is apparent from Article 58 of the Statute of the Court of Justice of the European Union that the grounds of appeal must be based on arguments made in the proceedings before the General Court. Moreover, according to Article 170(1) of the Rules of Procedure, 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 confined to a review of the findings of law on the pleas and arguments debated before the General Court (judgment of 21 December 2021, Aeris Invest v SRB, C‑874/19 P, EU:C:2021:1040, paragraph 53 and the case-law cited).
