In challenging CAS decisions, what grounds are typically available?

• A. CAS decisions can be challenged on merits in national courts.
• B. CAS decisions can be challenged on limited grounds such as jurisdiction or procedural fairness.
• C. CAS decisions cannot be challenged at all.
• D. CAS decisions are automatically reversed if a national league disagrees.

Answer: (A)

Challenges to CAS decisions happen through a narrow set of grounds tied to the arbitration process, not through a re-weighing of the merits. The idea is to preserve the finality and efficiency of arbitration while providing a limited safety valve if the procedure or authority was faulty. Typically, issues raised focus on the arbiter’s jurisdiction or mandate—whether the CAS had the power to decide the dispute as framed by the contract or agreement—and on procedural fairness, such as whether the parties were treated fairly, given proper opportunity to present their case, and whether the arbitrator remained impartial. Depending on the governing law, grounds may also cover violations of mandatory law or public policy, where the award is so irregular as to violate fundamental norms. In short, you don’t challenge CAS awards on the merits in ordinary national court review; you challenge on these limited, process- and authority‑oriented grounds. The other options describe mechanisms that don’t align with how CAS challenges are normally structured: there is a pathway to challenge, but not a general merits review; and there isn’t automatic reversal simply because a league disagrees.
