Arizona DUI Trial in Absentia:
What State v. Ruiz-Estrada Means If You Missed Court
NOTICE: This case is a memorandum decision which means it is not for official publication under Arizona Supreme Court Rule111(c). The decision is not precedential and may be cited only as authorized by rule. Although not official precedent it does give an indication of what the court of appeals thinks about these issues.
An Arizona appeals court just confirmed that a jury can convict you of DUI — and you can be sentenced — even if you were never in the courtroom. Here is what happened, what the law says, and what to do if it applies to you.
In April 2025, the Arizona Court of Appeals issued a ruling that every person charged with DUI in Arizona should read. In State v. Ruiz-Estrada, 2 CA-CR 2024-0164, the court upheld a DUI conviction entered after the defendant stopped showing up to court, disappeared for years, and was ultimately tried and convicted without ever walking into the courtroom. The case raises important questions about what rights you have, when you can lose them, and what happens if you are in a similar position right now.

What Happened in This Case
In January 2013, Arthur Ruiz-Estrada crashed his car into another driver’s vehicle in Pima County. The other driver suffered a broken thumb, and her car was totaled — later valued by insurance at roughly $9,200. When police arrived, they observed Ruiz-Estrada with red and watery eyes, slurred speech, an unsteady stance, and a strong odor of alcohol. A sealed bottle of vodka was found in his car. He reportedly told officers he could not believe what he had done to his boss’s vehicle.
Ruiz-Estrada was charged with aggravated assault with a dangerous instrument (his vehicle), criminal damage, and multiple DUI counts. He was arraigned, appeared at some early hearings, and then began missing court dates. A bench warrant was issued. He eventually appeared and had the warrant quashed in August 2014 — but then missed court again in October 2014. Another bench warrant was issued.
Trial was scheduled for November 2015. Ruiz-Estrada did not appear. His own attorney told the judge he had not been able to reach his client since 2014. The court noted that Ruiz-Estrada had been warned at least three times that trial could proceed without him. Trial went forward. The jury convicted him of DUI, aggravated assault, and criminal damage.
Then nothing happened — for nearly a decade. In May 2024, Ruiz-Estrada was arrested on the outstanding bench warrant. He was sentenced in 2024 to concurrent three-year probation terms, with one-year jail terms for the assault and damage charges. He appealed.
What the Arizona Court of Appeals Decided
Issue 1: Was It Legal to Try Him Without Him Present?
Yes, the court ruled. Arizona Rule of Criminal Procedure 9.1 permits a court to proceed with trial in a defendant’s absence if the defendant had actual notice of the trial date, notice of the right to be present, and notice that trial could go forward without them. All three conditions were satisfied here: Ruiz-Estrada had signed written acknowledgments on multiple occasions, had been verbally admonished at hearings, and his attorney confirmed no contact since 2014.
A court may infer that a defendant’s absence from trial is voluntary if the defendant “had actual notice of the date and time of the proceeding, notice of the right to be present, and notice that the proceeding would go forward in the defendant’s absence.”
The court also noted that an out-of-custody defendant has a duty to stay in contact with both the court and their attorney. Ruiz-Estrada cut off all communication. That failure, combined with the prior warnings, was enough to treat his absence as voluntary — and to proceed without him.
Critically, the court confirmed there is no requirement that a defendant be re-warned of their rights after every single continuance, and no requirement that the court hold a special hearing to determine voluntariness of absence unless the defendant asks for one. Ruiz-Estrada’s attorney made no attempt to rebut the voluntary-absence presumption at trial, and Ruiz-Estrada himself said nothing about voluntariness at sentencing years later. The court found no abuse of discretion.
Issue 2: Was There Enough Evidence to Convict Without a Blood Test?
Yes, again. This is the ruling’s second significant point for anyone facing a DUI charge in Arizona.
Important for DUI defendantsArizona’s standard DUI statute does not require the prosecution to prove a specific blood alcohol concentration. Under A.R.S. § 28-1381(A)(1), it is enough to prove you were driving while impaired to the slightest degree. The court in Ruiz-Estrada upheld the conviction based entirely on officer observations and a toxicologist’s testimony — no blood alcohol number needed.
Ruiz-Estrada argued that the blood sample evidence had chain-of-custody problems and should have been discounted, making the remaining case entirely circumstantial. The court disagreed. Because the DUI charge under A.R.S. § 28-1381(A)(1) requires only impairment to the slightest degree — not a specific BAC — the physical observations alone were sufficient. Red eyes, slurred speech, swaying, the odor of alcohol, the crash itself, and expert testimony confirming those symptoms are consistent with alcohol consumption: that was enough for a reasonable jury to convict.
It is unlawful to drive or be in actual physical control of a vehicle “while under the influence of intoxicating liquor” and “impaired to the slightest degree.” No specific blood alcohol concentration is required for a conviction under this subsection.
What This Ruling Means for You
If you are currently charged with DUI in Arizona, or if you have missed a court date or have an outstanding bench warrant, the Ruiz-Estrada decision has direct practical consequences.
You can be convicted in your absence — and it is legal
Arizona courts are not required to wait for you. If you have signed an acknowledgment at arraignment (virtually every defendant does), you have already been put on notice that trial can proceed without you. Missing court does not stop the clock; it starts it.
A conviction can follow you for over a decade
Ruiz-Estrada was convicted in 2015 and arrested in 2024. The bench warrant never expired. It showed up on routine law enforcement checks. There is no statute of limitations on a bench warrant; you cannot wait it out.
You do not need to fail a breath test to be convicted of DUI
If you refused a breath or blood test, or if you believe the test results can be challenged, that does not automatically win your case. The prosecution may pursue conviction under A.R.S. § 28-1381(A)(1) based on observable signs of impairment alone. An experienced DUI attorney can evaluate whether the physical evidence in your case is sufficient and how to challenge it.
Your attorney cannot protect you if you disappear
The court placed significant weight on the fact that Ruiz-Estrada stopped communicating with his own lawyer. In Arizona, an out-of-custody defendant has a legal duty to stay in contact with counsel. When defendants go silent, attorneys lose the ability to file motions, negotiate plea agreements, or mount any meaningful defense.
What to Do If You Are in a Similar Situation
- Do not ignore a bench warrant. It will not expire. Every traffic stop, every background check, every interaction with law enforcement is an opportunity for arrest. Address it proactively.
- Call a DUI attorney before you go to court. An attorney can often file a motion to quash a bench warrant and negotiate your return to court in a way that minimizes your risk of immediate custody. Do not walk into the courthouse alone.
- Understand the DUI charges against you fully. If you were charged under A.R.S. § 28-1381(A)(1), the prosecution does not need a BAC number to convict you. The strength of the physical evidence in your case — what officers observed, what they documented — matters enormously.
- Act within 30 days of a DUI arrest. Arizona law gives you only 30 days from a DUI arrest to request an MVD hearing and contest your license suspension. That deadline does not pause while you decide what to do.
- Stay in contact with your attorney. The single most avoidable mistake Ruiz-Estrada made was cutting off all communication. Courts interpret silence as indifference. Your attorney is your best asset — but only if they can reach you.
Frequently Asked Questions
Can an Arizona court really hold a DUI trial without me present?
Yes. Under Arizona Rule of Criminal Procedure 9.1, if you had actual notice of your trial date, notice of your right to be present, and notice that trial could proceed without you — all of which are standard arraignment acknowledgments — the court can and will proceed in your absence. The Ruiz-Estrada ruling from April 2025 confirms this. The defendant was convicted on DUI, aggravated assault, and criminal damage charges at a trial he did not attend.
What happens if I miss a DUI court date in Arizona?
The court will typically issue a bench warrant for your arrest. If you have previously been warned that trial can proceed without you, the court may schedule and conduct your trial anyway. You could be convicted and sentenced without being present. The warrant will remain active indefinitely — there is no expiration. Contacting an experienced Arizona DUI attorney as soon as possible is critical.
Can I be convicted of DUI in Arizona if I did not take a breath or blood test?
Yes. Arizona’s standard DUI statute, A.R.S. § 28-1381(A)(1), prohibits driving while impaired to the slightest degree — and does not require the prosecution to prove a specific blood alcohol concentration. In State v. Ruiz-Estrada, the court upheld a DUI conviction based entirely on officer observations: red watery eyes, slurred speech, unsteady gait, strong odor of alcohol, and a crash — with no blood alcohol number in evidence.
I have an outstanding DUI bench warrant in Arizona. What should I do?
Contact an Arizona DUI attorney immediately — before the warrant leads to an arrest at a time and place you do not control. An attorney can often file a motion to quash the warrant and arrange a voluntary court appearance on terms that reduce your risk. Do not try to handle a bench warrant situation on your own.

How long does an Arizona bench warrant stay active?
Indefinitely. Bench warrants in Arizona do not expire. The Ruiz-Estrada case is a striking example: the defendant was convicted in 2015 and the bench warrant sat open until his arrest in May 2024 — nearly nine years later. There is no safe amount of time to wait.
