Government of Indiana
The Supreme Court of Indiana is the highest judicial body in Indiana. The court oversees the lower courts and commissions that jointly make up the judicial branch. The other courts include the Indiana Tax Court, the Indiana Court of Appeals, and circuit, superior, and city or town courts. Every county in the state has a circuit court, in which all matter of suits may be filed, and the larger cities (such as Indianapolis, Fort Wayne, South Bend, Evansville, and Terre Haute) have courts of concurrent jurisdiction that act as superior or municipal courts. The courts are assisted by several commissions that are also part of the judicial branch, including the Judicial Nominating Commission.
United States Constitution
Courts established by the Constitution can regulate government under the Constitution, the supreme law of the land. First, they have jurisdiction over actions by an officer of government and state law. Second, federal courts may rule on whether coordinate branches of national government conform to the Constitution. Until the twentieth century, the Supreme Court of the United States may have been the only high tribunal in the world to use a court for constitutional interpretation of fundamental law, others generally depending on their national legislature.
