themselves the: initiative of laws, referendum of other legislative acts, and recall of office holders. Judiciary The judiciary of Colorado is defined by Article VI of the Colorado Constitution as well as the law of Colorado. The administration of the state judicial system is the responsibility of the Chief Justice of the Colorado Supreme Court as its executive head, and is assisted by several other commissions. Colorado courts include the: Colorado Supreme Court, Colorado Court of Appeals, Colorado district courts, Colorado county courts, Colorado water courts, Colorado municipal courts. All of the courts above, other than municipal courts and Denver's county court, are part of the state court system. In Denver, county and municipal courts are integrated and are not part of the state court system for administrative purposes, and the Denver Probate Court and the Denver Juvenile Court have jurisdiction over probate and juvenile matters, respectively. Outside Denver, these matters are within the jurisdiction of the district courts. Most crimes in Colorado are prosecuted by a district attorney. One district attorney is elected for each of the state's 22 judicial districts in a partisan election. The state attorney general also has power to prosecute certain crimes, and in rare circumstances a special prosecutor may be appointed to prosecute a crime on a case by case basis. Municipal ordinance violations are prosecuted by city attorneys. Local government Colorado is divided into 64 counties. Counties are important units of government in Colorado since the state has no secondary civil subdivisions, such as townships. Two of these counties, the City and County of Denver and the City and County of Broomfield, have consolidated city and county governments. A municipality may extend into multiple counties. The 272 Colorado municipalities operate under one of five types of municipal governing authority: 2 consolidated city and county governments 61 cities and 35 towns that are home rule municipalities 12 statutory cities 161 statutory towns 1 territorial charter municipality There are no township governments in Colorado, but there are more than 4,000 special districts. See Active Colorado Local Governments. Other political subdivisions include the University of Colorado Hospital Authority which supports education, research, and public service activities, and which provides patient care through UCHealth (University of Colorado Health). Other governments There are two federally recognized tribes that overlap Colorado: the Southern Ute Indian Tribe and the Ute Mountain Ute Tribe. There are no other known state-recognized tribes.
