Criminal Court Process for Bonneville County Idaho
A Guide to Criminal Cases in the Bonneville County Courts at Idaho Falls
Bonneville County is the population center of eastern Idaho, and its criminal docket is the busiest in the region. Cases are filed at the county courthouse in Idaho Falls, the county seat, a growing city on the Snake River that is home to the Idaho National Laboratory's main offices. Like the rest of Idaho, Bonneville has a single District Court with a Magistrate Division. Magistrates handle misdemeanors, infractions, initial appearances and felony preliminary hearings; district judges hear felonies after they are bound over. The county is the largest member of the Seventh Judicial District, whose other counties are Bingham, Butte, Clark, Custer, Fremont, Jefferson, Lemhi, Madison and Teton.

It is a large facility, with an operational capacity of several hundred beds, so Bonneville rarely needs to send its own pretrial inmates elsewhere. Your citation, bond paper or summons lists the courtroom and time. Select the type of charge below to see how it is handled.
- Misdemeanor charges in Bonneville County (trespass, petty theft or petit theft from a store)
- Felony charges in Bonneville County (grand theft, arson or felony DUI)
- Violent felony charges in Bonneville County (armed robbery, aggravated battery or kidnapping)
Misdemeanor charges in Bonneville County (trespass, petty theft or petit theft from a store)
In Bonneville County, misdemeanor cases are heard by magistrate judges at the Capital Avenue courthouse in Idaho Falls. Two different prosecuting offices share the work. Offenses committed inside Idaho Falls city limits are generally prosecuted by Idaho Falls City Prosecution, a division of the City Attorney's Office. Misdemeanors from the unincorporated county, from smaller cities such as Ammon, Iona and Ucon, and from Idaho State Police stops are typically handled by deputy prosecutors in the Bonneville County Prosecuting Attorney's magistrate court branch. Your paperwork will show which office filed the charge.
After an arrest
A large share of Bonneville misdemeanors begin with a citation and a court date rather than a trip to jail. People who are booked go to the Bonneville County Jail. Idaho law requires a probable cause finding within 48 hours of any warrantless arrest, and the arrested person must see a magistrate without unnecessary delay. During that initial appearance, the Idaho Falls magistrate explains the charge and the person's rights and decides on bail or release conditions.
Your right to a lawyer
Bonneville County is one of the counties where the Office of the State Public Defender, which took over public defense across Idaho on October 1, 2024, runs its own staffed office. Anyone facing possible jail time who is unable to pay for a defense lawyer can apply at the courthouse; the magistrate decides whether to appoint the Bonneville SPD office on D Street, reachable at (208) 701-7300. If that office has a conflict, the appointment goes to the SPD's Alternate Counsel Division.
How Bonneville misdemeanors end
Most cases are settled by negotiation before trial. Idaho Falls magistrates frequently grant a withheld judgment under Idaho Code 19-2601; if the defendant completes probation, the Bonneville County guilty plea may be set aside and the Bonneville County case dismissed. Bonneville County has one of the most extensive sets of treatment courts in the state, including a misdemeanor/DUI drug court, a mental health court, a domestic violence court and a veterans treatment court that serves the Seventh District. A Bonneville County defendant who pleads not guilty is owed trial within six months, and a misdemeanor jury in Bonneville County seats six detainees who must reach a unanimous verdict.
Sentencing ranges
- Typical Idaho Falls misdemeanor: no more than 6 months in the Bonneville County Jail and a fine of no more than $1,000; certain offenses carry up to a year.
- First DUI in Bonneville County: up to 6 months in jail and a fine up to $1,000; a 30-day absolute driver's license suspension plus another 60 to 150 days, with restricted privileges sometimes allowed; a required alcohol assessment; and an ignition interlock device for a year after the Bonneville suspension ends unless an exception applies.
- Probation: commonly paired with fines, counseling or community service in place of jail time.
Many Bonneville misdemeanors are wrapped up within one to a few months; those set for trial or placed in a treatment court run longer.
Felony charges in Bonneville County (grand theft, arson or felony DUI)
All felonies in Bonneville County, including those that start with an Idaho Falls Police arrest, are prosecuted by the Bonneville County Prosecuting Attorney, whose criminal division appears in juvenile, magistrate and District Court. A felony case begins before a magistrate, then moves to one of the Seventh District judges assigned to the Idaho Falls courthouse once the charge is bound over. Defendants unable to post bail are held at the Bonneville County Jail throughout.
The Idaho Falls path to District Court
The prosecutor most often starts a felony by filing a complaint. A preliminary hearing must be held within 14 days if the defendant is in custody and 21 days if released, though the court can extend those deadlines. The magistrate decides if probable cause supports the charge. In some cases the prosecutor goes to a Bonneville County grand jury instead, and an indictment takes the place of the hearing. Once a case is bound over, the prosecutor files an "information," and the defendant is arraigned before a district judge.
Defense counsel
The Bonneville County office of the State Public Defender represents most felony defendants who qualify for appointed counsel. A person applies at the courthouse, and a judge alone can make the appointment. Conflict cases, such as co-defendants who cannot share a lawyer, go to the SPD's Alternate Counsel Division.
Trial, plea and sentencing
After the District Court arraignment, Idaho's speedy-trial statute calls for trial within six months. Most Bonneville felonies resolve by plea; those tried go to a 12-member jury that must be unanimous. Idaho sentences are unified: a fixed minimum term plus an indeterminate term, with parole decided by the Commission of Pardons and Parole. Judges may retain jurisdiction for up to 365 days, a "rider" during which the defendant completes IDOC programming before the court considers probation. Idaho Falls district judges may still withhold judgment in certain felony cases. Bonneville's felony drug court, young adult court and mental health court give qualifying defendants supervised treatment as an alternative to prison. A third felony conviction exposes a defendant to the persistent violator enhancement of 5 years to life. Bonneville County felony cases generally take 6 to 18 months.
Violent felony charges in Bonneville County (armed robbery, aggravated battery or kidnapping)
Homicides, sexual assaults and armed robberies in Bonneville County follow the standard Idaho felony route, but the stakes, the evidence and the length of the case grow considerably. The Bonneville County Prosecuting Attorney handles these prosecutions, often with experienced trial deputies assigned from the start, and the cases are heard by Seventh District judges in Idaho Falls.
Bail and pretrial detention
Under the Idaho Constitution, all defendants are bailable except in capital cases where the proof is evident or the presumption great. For other violent charges, bail is allowed but is usually set high, and release conditions can include no-contact orders and electronic monitoring. Defendants who cannot meet those terms remain at the Bonneville County Jail in Idaho Falls until trial or plea.
Representation in serious cases
Qualifying defendants are represented by the State Public Defender's Bonneville County office at (208) 701-7300, or by the Alternate Counsel Division if there is a conflict. When the State gives notice that it will seek death, the court must appoint attorneys qualified to try capital cases.
Idaho penalties for violent felonies
- Murder in the first degree: life in prison with no less than 10 years fixed, or death if the prosecution filed notice and the jury finds an aggravating circumstance.
- Murder in the second degree: no less than 10 years, up to life imprisonment.
- Rape: a term of 1 year to life.
- Robbery: a term of 5 years to life.
- Firearm or deadly weapon: Idaho Code 19-2520 permits up to 15 additional years for using one in certain felonies.
The persistent violator law can raise the sentence for a defendant with two earlier felonies. Crime victims in Bonneville County have constitutional rights under Article I, Section 22, including notice of hearings, the right to be present and heard at sentencing, and restitution for their losses.
Expected duration
Forensic testing, expert witnesses and heavy pretrial litigation mean a violent felony in Bonneville County commonly lasts one to three years or more. A capital prosecution can take substantially longer.

Criminal Court Process for Bonneville County Idaho
Bonneville County Idaho Criminal Court System - Definitions
It might be helpful to define some words that will be used on this site, when explaining the Idaho Court System and how it works. The definitions on this site are for general information and not legal advice. It is always preferred to follow information given by your attorney or local authorities.
If you scroll down below this content, and the listing of the courts in Bonneville County, you will find a simple flowchart diagram and a video that will help you visualize the stages of the Criminal Court Process.
Arrest is when Idaho, Bonneville County or local police take a person into custody and start the legal process. The arrested person may or may not be immediately jailed.
In less serious crimes, the person may only be given a citation ordering that they appear in magistrate or Bonneville County court on a certain date. In cases involving more serious crimes, the person is usually placed in the county jail until an arraignment, or a judge decides the next step.
Booking is when the Bonneville County sheriff or local police gather information such as the detainee’s name, address and why the person is being arrested. Booking also includes fingerprinting, criminal history, investigation, and verification of identity. Bail for lower-level crimes may be set right after booking so the arrested can “bail or bond out” before being detained.
The prosecution, sometimes called “the government” or “the people” or “the state” is the side that presses the charges and seeks punishment for the offense. These are attorneys that work for the state of Idaho, Bonneville County or a city or town. The prosecuting attorney for Bonneville County or the district is called the Deputy Prosecutor or Deputy County Prosecutor. A U.S. Attorney prosecutes federal cases.
Jurisdiction is an important term in the court system that means whether a court has the obligation or duty or right to handle a case. For example, if you run a red light in your town or city, a magistrate court would likely have jurisdiction over your case, but the next town or city over would not have jurisdiction over your case. If you attempted to flee from police when they attempted to stop you after you ran the red light, it becomes a more serious crime, and the magistrate court might not have jurisdiction so you might be assigned to a higher-level court that has jurisdiction over the more serious crime. Jurisdiction varies from state to state and sometimes county to county.
Arraignment is when a judge determines whether the charges are supported by the prosecution’s initial evidence and tells the arrested what they are charged with, and the person says whether they are guilty or not guilty. At this time, the person is called the defendant, and the opposing side is called the prosecution. If there is reason to believe that the arrested is guilty, the judge will set bail conditions or send the defendant to jail or release them ROR (release on recognizances). An arraignment is not a trial, and the defendant is entitled to a trial within a reasonable amount of time after the arraignment.
Bail is money paid that is held by the Bonneville County or magistrate court to make sure that the arrested does not flee the area before their trial. Bail amounts and other conditions are determined at the arraignment. Once the case is over, the bail money is returned to the defendant. If a person does not pay bail, they remain in the Bonneville County Jail until their trial.
Bail can be denied if the court feels that the arrested would be a danger to others if released. Sometimes the court decides that there is a good chance that the arrested will show up for trial and not flee so they are released on their own promise, or recognizance without having to pay bail.
A bond proceeding is the determination of how much bail is to be paid and usually happens at the same time as an arraignment. During bond proceedings, the defendant can have an attorney present but does not have the right to an attorney. A judge or court officer in the {county extended} or magistrate court sets bail. Judges in Idaho rely on a statewide bail schedule, which sets out a recommended range of bail amounts for different offenses. Judges can still exercise discretion in setting bail above or below the recommended range.
It is always important to have family involvement after being arrested. Not only can they make calls and communicate on your behalf (not all bond companies will accept collect calls), but family support will show the court that there are people who will make sure that the defendant makes it to court, not only for the defendant’s own good, but because they may have signed bond paperwork and responsible to pay if the defendant does not show in court. Chances of obtaining a bond from a bond company or clerk of court are better if family is involved.
(There have been phone scams where a bond company calls and informs a person that their family member has been arrested and they ask for financial information. A bondsman will not call asking for money without involvement of the arrested.)
A judicial public bond or personal recognizance bond is a bond where someone representing the defendant signs paperwork promising to pay the money if the defendant does not show up to court. If the defendant does not show, the full amount will be due and the people who signed the paperwork will be responsible for paying the court.
Cash percentage in lieu of bonds. If the bond order permits, the defendant pays a percentage of the amount, (sometimes up to 100%) to the court, which then holds the money until the case is over. The amount is returned if the defendant is acquitted or the case is dismissed, or it can be used toward paying any court fines incurred by the defendant.
Surety Bond is when defendant pays a percentage of the bond amount (usually 10–15%) to a professional bondsman or bail bond company licensed to do business in Idaho, {county extended}. The bondsman then signs the bond on behalf of the defendant. The defendant does not receive any of the money back. If the bondsman feels the defendant is a flight risk, they can refuse to give a bond or charge a higher fee. For example, a bondsman may determine a defendant is a flight risk if they are from a state other than Idaho.
A Property Bond is a bond in which the bond is pledged in land or home real estate (mobile homes are not accepted). Usually, the property must be in Bonneville County, and it must be worth at least the amount of the bond.
A criminal defense attorney (also called lawyer or counsel) is hired or retained to represent the arrested as early as possible after the arrest.
If there is a chance that the case might go to trial and the defendant cannot afford an attorney, the 6th Amendment of the U.S. Constitution requires that the court provide an attorney. This is called indigent representation and a public defender or assigned attorney would represent the defendant in all proceedings.
Indigent representation is only available misdemeanor and felony cases that could result in jail time, juvenile cases, and certain appeal cases. In Idaho, individual counties determine how the indigent representation will be managed. Some counties have public defenders, and some counties assign or contract for indigent services. Your court will be able to provide you with information on how to apply for indigent legal representation.
For less serious cases or civil cases, there are pro bono volunteers who volunteer legal services for free or for a small fee. They often will hold clinics to teach people how to represent themselves in court or expunge their record which means to legally erase or eliminate a criminal or arrest record from public view. This website provides contact information for pro bono services in Idaho.
Many courts will provide forms and help for people who want to represent themselves, called pro se. Here is a link for legal self-help centers in Idaho.
A district court can refer to the first level of the legal system, or a minor court. District courts are in the community. A district court can also refer to a U.S. Federal District Court that hears federal cases. There is one U.S. federal district court in Idaho, with offices throughout the state. It is important that you check the address of the court you are to appear in rather than to ask someone because that person might give you directions to the wrong “district” court. Being late to court can land you in custody as well.
Pretrial proceeding is the process where both sides (prosecution and defense) gather information, interview witnesses, request records, videos etc. Pretrial proceedings also include communications with the judge assigned to the case and these appearances are either in person or by on-line conferencing. Some pretrial proceedings may not require a defendant’s appearance, allowing an attorney to appear in their place. The information that is gathered is called discovery and both sides must share the information that they have gathered. This information does not include conversations between the arrested and their attorney.
Most cases do not go to trial because both sides reach a plea deal, where both sides try to reach a reasonable punishment based on what was learned in the pretrial proceedings. A plea deal can only happen if the accused person admits they are guilty in exchange for a lighter punishment. The reason they must admit guilt is because it would not be fair to punish someone who claims they are not guilty. There are times in plea bargaining when the prosecution agrees to give a lighter sentence in exchange for information leading to the arrest of a more serious criminal related to the crime.
Trial is where both sides share their information in front of a judge or a judge and jury. After listening to all the evidence, the judge or jury decides the verdict which is whether the person is guilty or not guilty. If a court has only a judge hearing both sides, it is called a bench trial. If a jury is selected, it is called a jury trial. If the defendant is found not guilty, they are released. If they are found to be guilty, the next step is sentencing.
Sentencing is the punishment that the judge decides the person should get. This could be jail or prison time, fines, community service, probation, or a combination.
Appeal is asking for a higher court to hear the case again at an appellate court. If the accused person thinks something went wrong at trial or has new information that was not available during the trial or that the sentence is too harsh, the defense attorney can ask for an appeal. It is not unusual for an appeal when there is a long jail sentence, but an appeal can be denied if the appellate court feels that the original trial or sentencing was fair.
Idaho Felony vs Misdemeanor
In Idaho, misdemeanors are not divided into classes or types and are punishable by imprisonment in a county jail for up to 6 months or up to $1000 or both.
A felony crime is a more serious crime than a misdemeanor and is punished by prison time in a state prison. Examples of felony crimes are murder, rape, theft, aggravated assault, drug trafficking, kidnapping and identity theft. In Idaho, felonies are divided into felony of the first, second and third degree.
The Bonneville County Clerk of Court is an elected official whose responsibilities for Criminal Court’s administrative issues include receiving criminal warrants, receiving bail, creating the trial schedule, receiving fees, fines and maintaining court records.
A warrant is used to get someone to appear in court or to law enforcement. There must be good reason to believe that the person is involved in a crime. The warrant gives authority to arrest the person and search for evidence for the investigation of the crime.
A criminal summons is issued to request that a person appear in court at a particular time and date. It does not involve an arrest. A traffic ticket, summary citation or lesser misdemeanor could be considered a summons if you are given a court date.
A summary citation, commonly referred to as a ticket, is a criminal summons by a law enforcement officer either in person or via mail accusing the defendant of a minor offense, stating potential fine, listing the court having jurisdiction and instructions for addressing the issue. Defendants may or may not be required to appear in court or handle the matter by entering a plea via mail.
Fines are usually paid to the District Court or clerk of court and payment methods can be found on the District Court or Bonneville County Clerk of Court website. If you do not pay your fine on time, you can lose your driver’s license, must pay additional fees or even have a warrant for your arrest. It is important to read the instructions on the ticket issued by the police officer or court at the time of your arrest. For a parking ticket or summary citation, the fine amount and how to send payment should be on the ticket.
Idaho Criminal Court System - How it Works
In Idaho, the court system is made up of magistrate courts, district courts, courts of appeal and one Supreme Court. Idaho does not have municipal courts. It is important that you get the address of the court that you are to appear at because going to the wrong courthouse is not always an accepted excuse for not showing to court.
Magistrate courts hear all misdemeanors and juvenile cases (up to 18 years), including traffic arrests. Preliminary felony hearings can be conducted before being transferred for prosecution to the district court. Each county in Idaho has at least one magistrate judge who does not necessarily need to be an attorney.
District courts prosecute criminal felony cases from beginning to end. The district court in Idaho can also hear appeals from the magistrate court.
Juvenile court is conducted through the magistrate court.
Courts of appeal conduct review of cases on appeal from magistrate and district courts.
The Idaho Supreme Court is like our United States’ Supreme Court because it has a panel of judges that rule on matters that have to do with someone’s constitutional rights or policies and laws. The Idaho State Supreme Court deals with the state constitution or laws or policies. Sometimes the Supreme Court will hear criminal cases on appeal when there is a question on the state laws or procedures that lead to the appeal.
The criminal cases are usually referred from the district courts of appeal.
Specialty courts or treatment courts are being adopted in many states to handle cases that involve non-violent and first-time offender cases in a way to where the offender can retain a job or responsibilities while following specific orders of the court as returned court appearances, periodic evaluations or testing for substances. Idaho offers the following: Felony Drug court, Misdemeanor/DUI Drug court, DUI court, Child Protection Drug court, Juvenile Drug court, Mental Health court, Juvenile Mental Health court, Veterans Treatment court and Domestic Violence Drug court.
The following link will provide information and locations of the Idaho Treatment Courts.
FEDERAL COURT
Federal Court deals with crimes involving violations of United States laws. Federal crimes include federal drug trafficking, federal tax evasion and fraud that crossed state lines and include crimes that occur on federal property as post offices or federal buildings.
Cases involving crimes that involve the FBI or DEA or Immigration agencies are federal crimes. Terrorism is a federal crime.
There are some differences in the Federal court system as compared to the Idaho state court system. For example, the attorneys who work for the courts are called United States Attorneys and Federal judges are called District Court Judges (not to be confused by local state district courts).
Federal Magistrate Judges hear the case early on, but they do not decide on the cases at a trial like the Federal District Court Judges. In a federal case, a grand jury is used for indictments.
There is one U.S. Federal Judicial District in Idaho.
