Arizona criminal court system is the set of municipal, justice, and superior courts that handle misdemeanor and felony cases under Arizona law. Municipal and justice courts handle most misdemeanors and citations, while superior court hears felony cases and many contested matters, under A.R.S. 22-301 at azleg.gov. If you are charged in Phoenix or anywhere nearby, act fast. A first DUI under A.R.S. 28-1381(A)(1) or (2) is usually a class 1 misdemeanor, with at least 10 days in jail, a $250 minimum fine plus assessments, and 90-day license suspension. A second DUI can mean 90 days to 4 months in jail and longer revocation. Call a lawyer immediately to protect deadlines and request a court and MVD hearing before the deadlines expire.

How does the Arizona criminal court system work?
The Arizona criminal court system works by sorting cases into courts with different jurisdiction, then moving them through charging, hearings, motions, trial, and sentencing under Arizona law. Municipal and justice courts usually handle misdemeanors, while superior court handles felonies and many more serious proceedings, including jury trials and post-conviction matters.
The main jurisdiction statutes are A.R.S. 22-301 for justice courts, A.R.S. 22-402 for municipal courts, and A.R.S. 12-123 and related provisions for superior court authority. Arizona courts also follow the Arizona Rules of Criminal Procedure and local court rules, which control deadlines, release conditions, and how evidence is challenged.
What are the municipal, justice, and superior courts?
Municipal courts, justice courts, and superior court are Arizona’s three main criminal trial courts, and each one handles a different level of case. Municipal courts hear city ordinance violations and many misdemeanor state charges, justice courts hear misdemeanors and preliminary felony proceedings, and superior court is the state’s general jurisdiction trial court.
A.R.S. 22-402 gives cities and towns authority over municipal courts, while A.R.S. 22-301 limits justice court criminal jurisdiction. Superior court, by contrast, is where felony cases are filed, where jury trials usually occur, and where serious pretrial litigation and sentencing often happen after a case is transferred or indicted.
How does a case move from arrest to resolution?
A case usually moves from arrest to resolution by starting with a police stop or arrest, then an initial appearance, release conditions, charging, pretrial hearings, negotiation, and either dismissal, plea, trial, or sentencing. If the charge is a felony, prosecutors may file a complaint or seek a grand jury indictment in superior court.
Arizona defendants can challenge the legality of the stop, search, statements, or identification early in the case, because those issues can affect whether evidence stays in the case. Many cases resolve through plea negotiations, but the exact path depends on the charge, the court, and the evidence.
How do criminal cases play out in local Arizona courts?
Criminal cases in local Arizona courts often begin in the city or justice court closest to where the alleged conduct happened, then move toward dismissal, plea, or trial based on the facts and the prosecutor’s position. In practice, that means Phoenix, Mesa, Scottsdale, Glendale, and Tempe courts all handle different calendars, procedures, and case volumes.
If your case is in the East Valley or West Valley, local counsel matters because court rules, judicial assignments, and prosecutor practices can vary by courthouse.
