The present unified judicial  system is the product of a 1972 constitutional amendment and the implementing  legislation adopted in subsequent years.
	  
At the top of the system is a  five justice Supreme Court. Until 1980, justices were elected for eight-year  terms Under a constitutional amendment adopted that year, Supreme Court  justices no longer file petitions to have their names on the ballot, but are  instead subject to a retention election every eight years. All vacancies on the  Court are filled by gubernatorial appointment upon the recommendation of the  judicial qualifications commission. Justices represent each of five geographic  Supreme Court districts, and they elect among themselves the chief justice.
	  
The Supreme Court has limited  original jurisdiction. In practice, its work is almost entirely appellate. In  addition, the "Governor has the authority to require opinions upon  important questions of law involved in the exercise of his executive power and  upon solemn occasions."
	  
The state is also divided into  seven circuit court districts, each circuit electing a proportionate share of  the thirty-eight circuit court judges, which are the backbone of the system.  Judges are elected on a non-partisan basis for eight year terms. Vacancies are  filled by gubernatorial appointment upon the recommendation of the judicial  qualifications commission.
	  
The circuit court is considered  the keystone of the state's trial system and has broad jurisdiction. It has  exclusive jurisdiction over the trial of felonies and appellate jurisdiction as  specified by law. In civil matters, it tries cases that are beyond the  jurisdiction of the magistrate courts. It is the only court which may grant  divorces or annulments of marriage and determine the boundaries or title of  real property.
	  
Magistrate courts exist in each of the judicial circuits and function under the supervision of the presiding judge of the circuit court. Each circuit is authorized to have at least one full-time law-trained magistrate. Additionally, the presiding judge of each circuit is authorized to appoint lay magistrates to provide added judicial service for the counties and municipalities. The magistrate courts have limited jurisdiction.
