DUI Case Process

Criminal Procedure 101:

If you are charged with the crime of intoxicated driving, in Michigan called Operating While Intoxicated or just “OWI” then your case will go through various procedures or stages. It should be noted that the more broadly used acronym for OWI is DUI, which for our purposes is a synonym for OWI. These stages often required by either the United States Constitution, Michigan's Constitution, along with those imposed by various statutes and court rules. The general purpose of these rules is to ensure fairness to the accused while protecting society for a potentially dangerous person while their case is being decided by a judge or jury.


Your case will usually start with an arraignment. In some courts, depending on the exact charges, the arraignment might be combined with a pretrial (see below). The arraignment is designed to accomplish two things. The first is for the court to advise you of the nature of the charges against you as well as the applicable punishments. The second part is the scheduling of bond. Your attorney will usually “waive the formal reading” in which case the court will assume you already understand the charges and penalty. Often your lawyer will also tell the court that for purposes of arraignment you are “standing mute.” Thereafter the court will enter a plea of not guilty on your behalf. The court will then move on to address the issue of bond.

Court Rule on Bond Conditions

There are two parts to the bond. The first part is the determination of what amount of money is necessary for you to post to assure that you will appear in the future. This can be anywhere from a personal recognizance and where no money is due, to $100,000.00 or more.

The second part of the bond hearing at the arraignment will consist of the court determining what conditions are necessary to keep the community safe will you are free to move about within the community. In the context of an DUI case, that usually consists of your being ordered to not use alcohol or any kind of illegal drugs, often including marijuana, some type of alcohol and/or drug treatment, and possibly also, participation in therapy of support group meetings.

If you violate your conditions of bond you risk having your bond “cancelled” in which case you would remain behind bars during the time your DUI case is pending with the court.


Discovery refers to all of the documents and things that will be used by the prosecutor as evidence in your DUI case. Usually the discovery in a DUI case will consist of the narrative police report or written description by the police officer of everything observed at the roadside, any witness statements taken, if applicable an accident report, copies of any video recordings from the patrol vehicle or the body cam of the police officers involved, a copy of the report from the chemical test, which is the breath, blood or urine alcohol or drug test, the maintenance and calibration records of the instrument used to test your bodily alcohol or drug content, a booking and/or inventory sheet from your persons and/or car, and any other item the prosecutor may have as evidence in their file. Most often your attorney will be able to obtain all these things by providing the prosecutor with a written request. Rarely, judges need to become involved, and where necessary and appropriate will order the prosecutor to produce discovery. In Michigan the rules of discovery are reciprocal, meaning your attorney will be obligated to provide the prosecutor with any evidence they may have in their fiel.

Pre-trial Hearing

After the arraignment the case will be set for a pretrial. A pretrial is just that, a hearing that takes place before trial. The purpose of a pretrial is for the court to learn whether the case can be resolved without a trial, and to provide the prosecutor and defense with a scheduling order providing deadlines as to when discovery must be provided, motions filed etc. Often this will include a trial date and a plea cut-off date. After the first pretrial one of four things will happen: (1) a new date for pretrial will be provided, usually because discovery is ongoing and incomplete, (2) a motion or evidentiary hearing will be set, (3) a plea will be entered, or; (4) the case will be set or proceed to trial. Thus, a first pretrial is usually succeeded by the scheduling of another court date for one of these four options.

DUI Motions

If your lawyer thinks that the court needs to provide guidance on a legal issue, such as where the defense attorney thinks the charge is not supported by the evidence, or that some of the evidence that supports the charge is not admissible, then they may file a written legal argument called a motion. Most often motions will bring to the court’s attention and will address statutory and constitutional violations. An example would be where your attorney believes that you were unlawfully stopped or arrested. In this case your lawyer would write out his/her reasoning in support of this contention, cite any applicable case law, and ask the judge to dismiss your case. The prosecutor will respond, the judge will review both arguments, and make a ruling.

DUI Evidentiary Hearings

Very often a legal motion will require the court to review the facts of the case and apply these facts to the law cited by the parties. In those instances where facts are disputed or the investigation is incomplete, the court may wish to hear testimony from one or more witnesses. In such instances, the case will be set for what is called an evidentiary hearing. Because witnesses are called and cross-examined, these hearings might look very much like trials, but they are actually quite different. The burden of proof is less, and with an evidentiary hearing the court is usually looking at one narrow issue. The result is a legal ruling bearing on the case, the result is not a finding of guilt or acquittal.

The DUI Trial

Most DUI cases are resolved through plea negotiations. However, if you are unable to resolve your case this way then you may wish to set your case for trial. The purpose of a trial is to allow the jury to decide issues of fact. Issues of law or reserved for the judge.

The trial begins with jury selection. After the jury is impaneled the prosecuting attorney will make an opening statement. The defense can also make an opening statement but is not required to do so. The reason the defense can waive its opening statement is because the defense does not have a burden of proof. After the opening statement, the prosecutor will call witnesses. When the prosecutor is done calling witnesses the prosecution will rest. At this point the defense can call witnesses as well. But again, there is no obligation to call witnesses because the prosecutor has the burden of proof. After the case is completed the parties will give their closing arguments. Then the case goes to the jury for decision. If you are acquitted, meaning found not guilty, your case will be dismissed as if it never happened. On the other hand, if the jury convicts you then he will be sentenced. Most DUI cases not involving injury or death will take between one and three days to try.

OWI Case Length

Every case and court is different, but as a general rule, most DUI cases take between four to six months to fully resolve; however, every case is unique, and the details and procedures of your case will determine how long it takes to reach its conclusion. If your case is set for trial, this can significantly lengthen the amount of time your case takes to reach its conclusion. And if appeals are involved, your case can sometimes takes years to fully resolve.

Client Reviews
Patrick Barone is the ONLY choice for DUI defense. He was realistic from the start and made it a point to look at my case before taking my money. As a business owner, when I think of attorneys, I think of the "shark infested waters. Patrick is a shark alright, but his prey is not the client; it's justice for his client. Ten stars Patrick!! Chris F.
Attorney Patrick Barone was very helpful and helped me understand the charge and sentence absolutely clearly. He also guided me through step by step helping me form a statement. His instructions were clear and detailed. It was obvious he cared about me understanding every important detail within my case. I would absolutely recommend this defense firm to anyone in need. Aaron B.
The Barone Defense Firm is the firm I recommend. They are truly concerned about the person, not just the legal issue, but the person as well. They are the most knowledgeable defense firm that I am aware of, having actually written the book on DWI Defense. If you are faced with a DWI you will not find a more professional and skilled law firm. But, most importantly, they care about how the accused individual recovers his or her life when the case is complete. Very remarkable group of lawyers. William H.
