Questão jurídica principal
Whether the CAS panel was improperly constituted or biased
Decisão extraída
The challenge was inadmissible because Pechstein did not object during the CAS proceedings despite knowing the composition; in any event, the allegations did not establish objective doubts about independence.
Fundamentação extraída
A party must raise objections to arbitral independence immediately on pain of forfeiture. The generalized accusations about IOC influence, the president's alleged 'hard line', and the CAS secretary's role were speculative and insufficient.
