Effective Pre-Trial Motions Can Lead To A Dismissal Of A DUI Charge In Arizona

If a case cannot be resolved without a trial, both the defense and the prosecution are given an opportunity to file motions, called the pre-trial motions. A motion is simply a request made of the court to grant some relief in a case. Usually, motions request that some part of the State’s evidence be excluded from trial when the case goes to court. This evidence could include the breath or blood test result, or field evaluations.

Rule 16. Pretrial Conferences; Scheduling; Management

Pre-trial motion practices for both the prosecution and defense in DUI or criminal case are governed by Rule 16 of the Arizona Rules of Criminal Procedure. The following sub-sections are listed under Rule 16 of the Arizona Rules:

  • Purposes of a Pretrial Conference
  • Scheduling
  • Attendance and Matters for Consideration at a Pretrial Conference
  • Pretrial Orders
  • Final Pretrial Conference and Orders
  • Sanctions

Pre-trial Motions Defined Under Arizona Rules

The Pre-trial motion practices take place before the trial, following the defendant’s arraignment.

The following types of motions can be filed:

  • Motion in Limine
  • Motion to Suppress
  • Discovery Motion
  • Pitchess Motion
  • Motion to Strike Prior DUI/DWI Convictions

Once a pre-trial motion is filed, a short hearing is held with the judge where both the defense attorney and the prosecutor are present. Both sides are allowed to argue their position and the judge will then rule on it. This ruling could either be a ‘grant’ or ‘denial’. The court must decide every pretrial motion before trial unless it finds good cause to defer a ruling.
DUI Pre-Trial Motions

At a DUI pre-trial motion, the defense attorney can raise specific concerns and questions to the judge. These concerns could include:

  • Modifying release conditions that seem unduly harsh or unjustified
  • Reducing the charges from a felony to a misdemeanor
  • Excluding certain evidence or testimony from being admitted in court
  • Prohibiting the use of any prior conviction
  • Complete dismissal of charges

Your defense attorney may file any of these motions for a number of reasons. However, he or she must be able to present an effective argument for the court to be able to ‘grant’. Based on the ruling given by the judge, it determines whether or not your DUI case even goes to trial.

You also get an idea of how much negotiating room your DUI attorney has with the prosecution to get your charges reduced. In case the defendant is convicted of the crime, pre-trial motions assist the parties and the judge to determine the appropriate DUI penalties the person will be facing.

Court Provisions

According to the Arizona Criminal Rule of Procedure 16, the following provisions or requirements must be met:

  • Motions must be made 20 days before trial
  • Opposing party has 10 days to file their response
  • Motions to dismiss charges may be raised at any time

Any motion, defense, or objection that is not made timely will be precluded. However, exceptions may be granted by the court if reasonable diligence was exercised.

Contact An Experienced Attorney

Pre-trial motions are most effective when they are determined and filed by an experienced criminal defense attorney. An experienced attorney will know that the pre-trial motions have to be filed early and adequate legal research and proper legal citations must be included in the motion. He or she will also know that motions must be plausible and material.

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career focused on DUI Defense representation, having personally defended more than 4,100+ DUI clients in the past 18+ years.

If you’re looking for a divorce attorney, tax attorney, or civil attorney, then I can comfortably say: "I’m not the one for you".

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are "aggressive", or "will fight for you", are a dime a dozen. They use these phrases because that is what they think people want to hear. The truth of the matter is, being "aggressive" rarely gets the client anywhere in these court systems. Being "aggressive" isn’t the same as being good, and is often used to put on a show for a client to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the lawyers that claim to do DUI Defense... and Criminal Cases..., and Accident cases..., and Divorces. A Jack-of-all-Trades is a master of none. By handling all different sorts of cases, they take away from their ability to truly focus on DUIs, and keep up to date on the latest changes in DUI Defense Representation.

What I offer is intelligent, quality DUI Defense, at an exceptional price.

I am one of only a handful of Arizona DUI Lawyers that focuses solely on DUI Defense representation.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I produce DUI Legal Guides used by defense lawyers across Arizona.

I am one of the most award-winning DUI Defense Lawyers in Arizona; have been recognized nationally, including in a 2022 issue of USA Today; and there are only a few lawyers in Arizona who have personally defended more DUI cases than I have. I am also one of the most reasonably-priced DUI Lawyers, as I pride myself on charging a Flat Rate only for the legal services you need, and not for the legal services you don’t.

I am also the lawyer who people call once they realize that their original lawyer screwed something up, gave them false hope or false promises, or simply just took their money and didn’t do much on the case. You would be surprised at how often this happens.

Save yourself the trouble of hiring the wrong lawyer, and hire the right DUI Defense Lawyer from the start.

You can reach me on my personal cell phone: 480-720-7839.

Let me know if you have any questions!
