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.
Separation of powers under the United States Constitution
Many legislators hold the view that separation of powers means that powers are shared among different branches; no one branch may act unilaterally on issues (other than perhaps minor questions), but must obtain some form of agreement across branches. That is, it is argued that "checks and balances" apply to the Judicial branch as well as to the other branches—for example, in the regulation of attorneys and judges, and the establishment by Congress of rules for the conduct of federal courts, and by state legislatures for state courts. Although in practice these matters are delegated to the Supreme Court, the Congress holds these powers and delegates them to the Supreme Court only for convenience in light of the Supreme Court's expertise, but can withdraw that delegation at any time.
