As a Swiss arbitration organization, decisions of the CAS can be appealed to the Federal Supreme Court of Switzerland. Appeals of arbitration decisions are generally not successful, and no evaluation of the merits takes place, with the evaluation mainly based on whether procedural requirements have been met, and whether the award is incompatible with public policy. there have been seven successful appeals. Six of the upheld appeals were procedural in nature, and only once has the Federal Supreme Court overruled a CAS decision on the merits of the case. This was in the case of Matuzalém, a Brazilian football player. CAS decisions can be the subject of further appeal to the European Court of Human Rights.
