Maricopa County, Arizona

How a case moves here

Maricopa County follows Arizona law on arrests, release, and courts. These rules are the same in every county in the state; the full set covers prosecutors, defense, and jails too.

Who decides release first: A judicial officer sets release at the initial appearance. In Maricopa County, superior court commissioners, who are appointed lawyers, run the initial appearance court; elsewhere justices of the peace and municipal judges often do it. Arizona has no general jail bail schedule, though police may cite and release people for many misdemeanors.
A.R.S. sec. 13-3967 A.R.S. sec. 12-213 Ariz. Const. art. 2, sec. 22 A.R.S. sec. 13-3601
Time to see a judge: A person arrested must be taken before a magistrate within 24 hours, or released. If no complaint is filed within 48 hours of the initial appearance, the person must be released.

Money bail: Arizona allows money bail. A judicial officer releases a person on recognizance or on bail in an amount the officer sets, after weighing listed factors such as the charge, criminal history, danger, and the victim's views.
A.R.S. sec. 13-3967
Courts: The Superior Court, a statewide trial court with a branch in each county, tries felonies. Justice courts, run by justices of the peace in county precincts, and city municipal courts hear misdemeanors and petty offenses. Justice courts also hold felony preliminary hearings.

Judges and magistrates: In Maricopa, Pima, Pinal, and Coconino counties, the governor appoints superior court judges from a commission's list and voters decide in retention elections whether to keep them. In the other counties, superior court judges win nonpartisan elections. Either way the term is four years; justices of the peace are elected to four-year terms, and city councils appoint most municipal judges, some of whom need not be lawyers.

Read from the statutes and court rules cited, 2026-09-30. Rule 4.1 was read through the Supreme Court's own summary, not the rule text. Merit selection applies by constitution to counties of 250,000 or more; Coconino joined by vote in 2018. The constitutional no-bail rule for people in the country illegally (art. 2, sec. 22(A)(4)) was left out of the summary because federal courts struck down its statute in 2014; not re-checked.
