The Pennsylvania Commonwealth Court is a specialized court in the state of Pennsylvania that primarily handles cases involving state and local government agencies. It was established to provide a forum for disputes related to administrative law, including issues like zoning, taxation, and public employment. This court is unique because it serves as both a trial court and an appellate court for certain cases. Decisions made by the Commonwealth Court can be appealed to the Pennsylvania Supreme Court, making it an essential part of the state's judicial system.
