Kernrechtsfrage
Whether the CAS panel was irregularly composed because arbitrator Ulrich Haas lacked independence or impartiality
Extrahierter Entscheid
The circumstances relied on did not objectively create a legitimate doubt as to Haas's independence or impartiality; the panel was not irregularly composed.
Extrahierte Begründung
Prior expert missions for the AMA were limited, remote in time, and performed independently. A party-appointed arbitrator must be independent and impartial, but contacts with sports bodies inherent in CAS practice do not suffice absent concrete objective doubts.
