Kernrechtsfrage
Whether the CAS award violated public policy because the urine samples were allegedly not traceable throughout the chain of custody.
Extrahierter Entscheid
No. The Court held that the CAS could find the external chain of custody sufficiently established and that the challenge mainly attacked evidence assessment, which is not reviewable.
Extrahierte Begründung
The arbitral findings showed sealed kits, recorded transfers, secure storage, intact seals on receipt, and no concrete indication of tampering or substitution. The argument remained appellatory.
