Illinois Petition To Advance is a legal document used in the state of Illinois to apply for a court order to advance a case to a higher court. This petition is typically used when the court's ruling is challenged and the petitioner wants the case to be heard in a higher court. There are two types of Illinois Petition To Advance: Direct Appeal and Discretionary Leave. Direct Appeal is filed when a party believes that the court's ruling is incorrect and requests for the court to review the ruling, while Discretionary Leave allows the petitioner to request a leave of court to advance the case to a higher court.
