That’s not quite right either. Right about JR not being directly applicable, but not right that the court can’t have a supervisory role and look into procedural elements of the decision making. The Fallon case is the one to look at. Essentially the HC would step into a JR style role. If they didn’t see evidence in PL decisions that the high standards needed to assert fraud/deliberate bad faith CAS did (see projectrivers previous post on that) then the HC could effectively make them. The court won’t be the final decision maker, they’d send it back to the PL. But the steer would be v clear.
Just my take as an (ex) lawyer with a bit of experience in this.
Oh, and Panncik represented Fallon ;-)
