Question juridique clé
Whether the arbitration appeal was admissible despite the arbitration clause and CAS rules
Solution extraite
The appeal was admissible because no valid written waiver of the right to challenge the award was shown; a mere statement that the award is final is insufficient.
Motifs extraits
Art. 192 LDIP requires an express written waiver. The CAS rules invoked by the respondent merely paraphrase that rule and do not bar an appeal absent such waiver.
