I don't think the circuit court can arbitrarily interject itself in the proceedings of a lower court. I believe SP Smith would have to ask J Cannon to recuse herself and when she doesn't, he will have to file a motion with the circuit court to remove her, but what would be the grounds for recusal? Because she is ignorant of the law? Because she is stupid? Because she is a cult member? Not sure any of those qualify as legitimate reasons for the court to force her to recuse herself.
Of course I am not a legal expert.
