The courts which rank second highest in the Virginia judiciary are the Circuit Courts. The General Assembly has the power to arrange and re-arrange the judicial circuits of the state and to increase or diminish their number. However, no new circuit can be created containing less than forty thousand inhabitants according to the most recent census nor if such creation would result in reducing the number of inhabitants in any existing judicial circuit below forty thousand. There are thirty-seven judicial circuits in Virginia. The geographical composition of the circuit ranges from one county or city to five counties and one city. Each circuit has one judge chosen by the joint vote of both houses of the General Assembly for a term of eight years. He must possess the same qualifications when chosen as judges of the Supreme Court of Appeals and must live in the circuit area where the circuit court is located while he is in office. The number of sessions of the circuit courts to be held for each county and city is prescribed by law and the judge of one circuit may be required or authorized to hold court in another circuit or city. Circuit courts usually have original and appellate jurisdiction in (1) all civil cases involving twenty dollars or more and (2) certain criminal cases. Below the circuit courts in the court structure in Virginia are the city Hustings or Corporation Courts. They are courts of record also and have original jurisdiction except in cases of appeals from justices. These courts have the sole power to appoint electoral boards in cities where they are located. They have much concurrent jurisdiction with the circuit courts. They are criminal courts and can try cases of felonies committed within one mile of the corporation limits. There are sixteen such courts: Corporation Courts located in Alexandria, Bristol, Charlottesville, Danville, Lynchburg, Newport News, Norfolk (2), South Norfolk, Staunton, and Winchester; Hustings Courts located in Petersburg, Portsmouth, Richmond (2) and Roanoke. These city court judges must live in the city where the court is located. The Virginia Constitution divides the cities of Virginia into two classes as far as the judicial system is concerned: (1) cities having a population of at least ten thousand according to the last official census are called cities of the first class; (2) cities having a population of less than ten thousand according to the last official census are called cities of the second class. In each first class city there may be a corporation court in addition to a circuit court. In any city containing at least thirty thousand inhabitants, the General Assembly may provide additional courts with the number of judges it deems necessary for the public interest.
