An Illinois Petition for Rule to Show Cause is a legal document used to address a situation where a party doesn’t comply with an order or does not follow the rules of a court. It is a document filed with the court that requests the court to require the person to appear and explain why the court’s order was not followed. The Petition for Rule to Show Cause is a way to ask the court to issue a “rule” that the person must appear in court or face the consequences. There are two types of Illinois Petition for Rule to Show Cause: an Order to Show Cause and an Adjourned Show Cause. An Order to Show Cause is a court order requiring a party to appear in court and explain why a specific order has not been followed. An Adjourned Show Cause is a court order that requires a party to appear in court at a later date and explain why a specific order has not been followed.
