Thank you, that makes sense. I think I really just wanted to type His Honour Judge John Judge's name again although my question was also sincere and I appreciate your response!Not sure, honestly. I haven't followed the Daybell-Vallow case very closely, which is the only other murder case in Idaho that could provide an example of judge selection.
Perhaps Judge John Judge is just presiding over the arraignment, or presided over the GJ and so is signing off on the court orders leading to the arraignment.
I'm guessing based on watching other cases that by the time there is a prospective trial, things could be different in terms of which judge is available and best qualified or suited for the type of trial it will be, but don't know, and the Idaho Criminal Rules available online don't seem that specific.
