Overview of the Pennsylvania Courts

The Pennsylvania Constitution organized the judiciary into a Unified Judicial System, consisting of the Supreme Court, Superior and Commonwealth Courts, Courts of Common Pleas, and Minor Courts.  The Unified Judicial System of Pennsylvania has an interactive diagram of the courts with more information.

Dating back to 1684, the Supreme Court of Pennsylvania is the highest court in the Commonwealth and the oldest appellate court in the nation. It hears appeals from the Superior and Commonwealth Courts. Its decisions are binding on all state courts in Pennsylvania, and on all matters of Pennsylvania state law. It also possesses administrative power over the Unified Judicial System, with several committees and boards responsible for writing and enforcing rules for judges, attorneys, and litigants.  

The Commonwealth Court is an intermediate appellate court that is primarily responsible for matters involving state and local governments and regulatory agencies, including election cases, real estate tax appeals, eminent domain cases, zoning cases, and appeals from decisions made by state agencies. It also acts as a trial court when the Commonwealth itself is the plaintiff or defendant in a lawsuit.

The Superior Court is an intermediate appellate court with jurisdiction over civil and criminal appeals that do not fall within the Commonwealth Court's jurisdiction.

The Courts of Common Pleas are the trial courts of Pennsylvania; they also hear appeals from the Minor Courts. They are organized into 60 judicial districts that usually are coterminous with county borders, although some cover two counties. 

The Minor Courts are the first level of Pennsylvania's judiciary and are presided over by magisterial district judges and municipal court judges. They are responsible for matters such as preliminary arraignments, preliminary hearings, bail, and traffic violations.

In the federal judicial system, Pennsylvania is located within the Third Circuit.
