There's a bit of confusion as to how the process works in terms of putting a new State Comptroller in place. Ann Lousin [[ Lou-SEEN ]], who was a researcher during the 1970 Constitutional Convention, explains her take on the situation.
Lousin says Bruce Rauner would have the authority to fill the slot after January 12th, since he's the incoming governor. But some people have a different understanding of what the state's constitution actually means. It says the governor can appoint someone to serve until an "elected officer qualifies or until a successor is elected and qualified." Some people believe that gives Quinn the right to put someone in place until a new person is actually elected. Attorney General Lisa Madigan is supposed to weigh in on the matter soon.
