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.
Article Three of the United States Constitution
The Supreme Court is the only federal court that is explicitly established by the Constitution. During the Constitutional Convention, a proposal was made for the Supreme Court to be the only federal court, having both original jurisdiction and appellate jurisdiction. This proposal was rejected in favor of the provision that exists today. Under this provision, the Congress may create inferior (i.e., lower) courts under both Article III, Section 1, and Article I, Section 8. The Article III courts, which are also known as "constitutional courts", were first created by the Judiciary Act of 1789, and are the only courts with judicial power. Article I courts, which are also known as "legislative courts", consist of regulatory agencies, such as the United States Tax Court.
