Every state and every county within each state has different court levels. In Coconino County, Arizona, we have the Superior Court, the Justice Courts, the Municipal Courts, and the Juvenile Courts.
The Justice Courts hear traffic cases and some criminal cases, domestic violence cases, harassment cases, and hold preliminary hearings on felonies which will be heard in the Superior Court ultimately if probable cause is found then the case then gets transferred up.
The Municipal Courts hear misdemeanor traffic criminal cases such as driving under the influence, hit-and-run, and reckless driving where no serious injuries occur. This court also issues search warrants and hears domestic violence and harassment cases.
The Superior Court hears felony and misdemeanor cases and appeals from the lower courts, which are Justice and Municipal Courts.
The Juvenile Court hears all criminal cases where someone is under 18 years of age. There are exceptions to this when a person under the age of 18 is charged with committing a highly serious crime such as rape or murder, but those are rare instances in which someone who is a juvenile can be charged and tried as an adult.
Our court system in Coconino County Arizona also has different court programs such as Drug Court and Veteran's Court as forms of diversion and rehabilitation instead of typical prosecution.
