With the exception of a refusal or a revocation because of a court order, the individuals do have legal recourse through a reference hearing at that point, in which case the CFO would have to demonstrate that the decision which he or she took was reasonable.

If the judge determined that the decision of the CFO was not reasonable, then, as Paula has indicated, they would have to give consideration to reversing their decision.
