From GOHS Holiday DUI Task Force arrests to MCAO filings, our Tempe office is minutes from Central Court, positioning us to act fast across Phoenix metro courts.
Enforcement & Courts in Maricopa County
Maricopa County is Arizona’s most populous county and the hub of Phoenix metropolitan DUI enforcement. Countywide operations surge during the Holiday DUI Task Force coordinated by the Governor’s Office of Highway Safety (GOHS), which deploys thousands of officers during major holiday periods across Phoenix, Scottsdale, Mesa, Tempe, Chandler, Gilbert, Glendale, Peoria, Surprise & Goodyear. These concentrated patrols and checkpoints generate large arrest numbers that are filed quickly into the county’s court system.
Where your case lands in Maricopa County depends on the arrest location and charge level. Felony DUI cases are heard at Maricopa County Superior Court, with felony arraignments and trials commonly set at the Central Court building at 201 W Jefferson St, Phoenix. The Maricopa County Attorney’s Office (MCAO) prosecutes those Superior Court felonies and typically handles DUI misdemeanors in the county’s justice courts, while municipal DUI cases within city limits proceed in each city’s own court and are prosecuted by that city’s prosecutor’s office.
There are 26 justice court precincts in Maricopa County, grouped into six physical locations. If DPS, MCSO, or another agency arrests you in an unincorporated area or on a state highway within the county, your misdemeanor DUI may be filed in the applicable justice court precinct rather than a municipal court. Understanding the distinction between a justice court docket and a municipal docket in Maricopa County is critical because procedures, case calendars, and plea practices vary by location and by the prosecuting authority.
Prosecutorial policies in Maricopa County also shape outcomes. MCAO screens DUI files originating from countywide enforcement, seeks felony indictments where aggravated elements are present (e.g., suspended license or prior felony DUI), and coordinates with law enforcement for discovery and lab reports. Meanwhile, Phoenix Municipal Court and other city courts (such as Scottsdale City Court, Mesa Municipal Court, and Tempe Municipal Court) operate high‑volume DUI calendars with their own standing orders, local forms, and conference settings. A defense tailored to Maricopa County must account for the courthouse, the prosecuting office, and the realities of the Phoenix metro’s enforcement cadence.

That proximity allows rapid in‑person filings, prompt jail visits within the Maricopa County footprint, and same‑day appearances when urgent issues arise after a GOHS task‑force stop or a late‑night Phoenix metro arrest.
Firm leadership brings direct Maricopa County bench experience to your defense.

He left the bench in 2014 and founded this firm in 2016. Attorney David Tangren, a University of Arizona College of Law graduate and a former prosecutor with the Pima County Attorney’s Office, adds significant prosecutorial perspective that is readily applicable to MCAO negotiations and Phoenix‑area municipal court practice.

Penalties are influenced by venue. For example, plea cutoff dates, motion calendars, and trial assignment differ between Phoenix Municipal Court and a Maricopa County justice court precinct. MCAO felony policies at Superior Court also affect treatment offers on aggravated DUI aligned with the Central Court’s scheduling blocks. A defense plan in Maricopa County must fit the precise courthouse and prosecuting agency handling your file.
