To assist the Governor in carrying out his executive duties, numerous departments and agencies have been established by the Constitution or by legislative act. Most of the department names suggest the particular type of work for which each is responsible: the Department of Military Affairs, the Department of Law including the Division of Motion Picture Censorship and the Division of War Veterans' Claims, the Department of Accounts, the Department of Purchases and Supply, the Department of the Treasury, the Department of Taxation, the Department of State Police, the Division of Motor Vehicles, the Department of Corporations, the Department of Alcoholic Beverage Control, the Department of Labor and Industry, the Department of Agriculture and Immigration, the Department of Workmen's Compensation, the Department of Conservation and Economic Development, the Department of Education, the Department of Highways, the Department of Health, the Department of Welfare and Institutions, the Department of Mental Hygiene and the Department of Professional and Occupational Registration. The Division of Personnel, the Division of the Budget, the Division of Records and the Office of Civilian Defense are all located in the Governor's Office. Additional specialized commissions such as the Advisory Council on Virginia Economy, the Art Commission, the Safety Codes Commission, the State Library Board, the State Water Control Board, the Commission on Constitutional Government, the Potomac River Basin Commission and the Commission on Interstate Cooperation also participate actively in the carrying out of the financial, law enforcing, service rendering, conservation, preservation, and regulation functions of the executive department of the Commonwealth. The Judicial Department--Article VI concerns the Judiciary Department whose chief purpose is to interpret the laws properly. The State Constitution in Virginia provides for a Supreme Court of Appeals, Circuit Courts, City Courts and other inferior courts. The jurisdiction of these courts is regulated by law with the exception of jurisdiction granted specifically by the State Constitution itself. The General Assembly authorizes by law the appointment of judges pro tempore by the Governor.
