Pennsylvania Rule to Show Cause is a legal document that is issued by a court in Pennsylvania when a litigant fails to comply with an order or fails to appear in court. It is a court order that requires the party to appear in court and explain why the court should not take action against the party for failing to comply with the order or appear in court. There are two types of Pennsylvania Rule to Show Cause: Rule to Show Cause for Contempt and Rule to Show Cause for Default. Rule to Show Cause for Contempt is issued when a party fails to comply with a court order, while Rule to Show Cause for Default is issued when a party fails to appear in court. In both cases, the court order requires the party to appear in court and explain why the court should not take action against them.
