Facing Charges in Jefferson County, Idaho: How the Rigby Courts Work

Jefferson County lies just north of Idaho Falls in the upper Snake River valley, a farming county of small towns such as Rigby, Ririe, Menan and Roberts that has grown fast as a bedroom community. Its criminal cases are heard at the Jefferson County Courthouse in Rigby, the county seat. Idaho does not split its Jefferson trial courts into separate county and state systems. Instead, each county has one District Court with a Magistrate Division: magistrates take misdemeanors, Jefferson infractions, first appearances and felony preliminary hearings, and district judges take felonies after bind-over. Jefferson County is part of the Seventh Judicial District, together with Bingham, Bonneville, Butte, Clark, Custer, Fremont, Lemhi, Madison and Teton counties.

Offices involved in Jefferson County criminal cases:

  • Jefferson County Courthouse, Clerk of the District Court, 210 Courthouse Way, Suite 120, Rigby, ID 83442, (208) 745-7736
  • Jefferson County Prosecuting Attorney, Rigby, ID 83442 (contact through the courthouse)
  • Office of the State Public Defender, Jefferson County, 200 Courthouse Way, Rigby, ID 83442, (208) 701-7345
  • Jefferson County Jail, operated by the Jefferson County Sheriff's Office, Rigby, (208) 745-9210

The courthouse, the public defender's office and the sheriff's operations are clustered along Courthouse Way in Rigby. Anyone arrested in Jefferson County and held before trial is kept in the Jefferson County Jail under the sheriff's supervision. Pick a charge level below to follow a Jefferson County case of that type proceeds.

Misdemeanor charges in Jefferson County (battery, trespass or a first DUI)

Jefferson County misdemeanors are filed in the Magistrate Division at the Rigby courthouse. The elected Jefferson County Prosecuting Attorney brings misdemeanor charges under state law, whether the arrest was made by the Jefferson County Sheriff's Office, the Idaho State Police on U.S. Highway 20 or Interstate 15, or a local police department. Because the county has no large city, there is no separate big-city prosecutor's office handling a major share of the docket as in Idaho Falls or Boise.

The first 48 hours

Many minor offenses in Jefferson County end in a citation with a court date. When someone is arrested and booked into the Jefferson County Jail, Idaho law requires a judicial probable cause determination within 48 hours if there was no warrant, and an initial appearance before a Jefferson County magistrate without unnecessary delay. The Rigby magistrate covers the charge, the right to counsel and bail. All misdemeanors are bailable under the Idaho Constitution.

Public defense in Rigby

On October 1, 2024, the Idaho Office of the State Public Defender took responsibility for defending people who cannot afford a lawyer. Jefferson County has an SPD office of its own at 200 Courthouse Way, (208) 701-7345. Apply at the courthouse; the magistrate decides whether to appoint the office. Cases where the office has a conflict of interest are assigned to the SPD's Alternate Counsel Division.

Resolving the case

Most Jefferson County misdemeanors end with a negotiated plea. A withheld judgment under Idaho Code 19-2601 is common for first-time offenders; finishing probation allows the court to set aside the plea and dismiss. The upper valley counties of Jefferson, Madison and Fremont have shared treatment courts, including a Jefferson County misdemeanor/Jefferson DUI drug court and a Jefferson mental health court, for eligible Jefferson County defendants. A not-guilty plea triggers the right to trial within six months, and a Jefferson County misdemeanor jury in Jefferson has six members whose verdict must be unanimous.

Possible punishment

  • Most Jefferson County misdemeanors: a jail sentence capped at 6 months and a fine capped at $1,000, or both; a handful of offenses permit up to a year.
  • A first DUI in Jefferson County: up to 6 months in jail, a fine up to $1,000, a 30-day absolute license suspension followed by 60 to 150 more days (restricted privileges may be available), an alcohol assessment, and a one-year ignition interlock requirement after the suspension unless an exception applies.
  • Probation: the usual outcome, frequently combined with fines and classes.

Expect a Jefferson County misdemeanor to take one to several months, depending on whether it is tried.

Felony charges in Jefferson County (arson, aggravated assault or felony DUI)

Felony charges in Jefferson County are filed and prosecuted by the Jefferson County Prosecuting Attorney. The case begins in magistrate court in Rigby and, after probable cause is established, is heard by a Seventh Judicial District judge assigned to Jefferson County. People who do not post bail stay in the Jefferson County Jail for the life of the case.

Probable cause stage

Most Jefferson County felonies start with a complaint. The defendant has a right to a preliminary hearing within 14 days if jailed or 21 days if out of custody, and the court can extend either deadline. At the hearing, the magistrate decides whether the State has shown probable cause. A grand jury indictment is the alternative route and makes the preliminary hearing unnecessary. After bind-over, the Jefferson prosecutor files an "information" in District Court.

Arraignment and appointed counsel

The defendant enters a plea at arraignment in District Court, and the six-month speedy-trial period for felonies runs from that date. The State Public Defender's Jefferson County office handles most appointed felony cases; a judge must approve each appointment after the defendant applies at the courthouse. If the office has a conflict, the Alternate Counsel Division steps in.

Outcomes for Jefferson County felonies

Plea agreements resolve the majority of felony cases, and those that go to trial are decided by 12 jurors who must agree unanimously. Idaho uses unified sentencing, combining a fixed period with an indeterminate period, and the Commission of Pardons and Parole controls release after the fixed portion. A district judge may retain jurisdiction for up to 365 days, the "rider" program inside IDOC, and then decide whether probation is appropriate. A Rigby district judge may grant a withheld judgment to some felony defendants. The felony drug court serving Jefferson, Madison and Fremont offers intensive supervised treatment to those who qualify. A third felony conviction can bring a persistent violator sentence of 5 years to life. A felony here usually takes 6 to 18 months to resolve.

Violent felony charges in Jefferson County (aggravated battery, murder or rape)

Violent felonies are rare in Jefferson, a county of Jefferson's size, but when they occur they are prosecuted by the Jefferson County Prosecuting Attorney through the same complaint, preliminary hearing and District Court process that applies to other felonies. These cases demand more investigation and expert testimony, and the possible sentences are among the harshest a Jefferson judge can impose under Idaho law.

Holding the defendant

Idaho's constitution entitles every defendant to bail except in capital cases where the proof is evident or the presumption great. For other violent charges, a Rigby magistrate or district judge may set substantial bail and strict conditions. Defendants who cannot meet them are held in the Jefferson County Jail until the case concludes.

Lawyers for the defense

The State Public Defender's Jefferson County office, at (208) 701-7345, represents qualifying defendants in violent felony cases, with the Alternate Counsel Division covering conflicts. If the prosecutor files a notice seeking the death penalty, the court appoints counsel who meet Idaho's qualification standards for capital defense.

Sentences Idaho allows

  • First-degree murder: a death sentence, available only when the State has filed notice and the Jefferson jury finds an aggravating factor, or life with a fixed term of no less than 10 years.
  • Second-degree murder: between 10 years and life.
  • Rape: no less than 1 year, up to life in prison.
  • Robbery: no less than 5 years, up to life in prison.
  • Deadly weapon added: up to 15 more years under Idaho Code 19-2520 for using a firearm or other deadly weapon in certain felonies.

A defendant with two prior felony convictions may also face the persistent violator enhancement. Victims of violent crime in Jefferson County are guaranteed rights under Article I, Section 22 of the Idaho Constitution, including notice, the right to attend Jefferson hearings, the right to speak to the Jefferson judge before sentencing, and restitution.

Length of the case

A violent felony prosecution in Jefferson County typically lasts one to three years or more. Capital cases take the longest because of separate sentencing proceedings and mandatory review.

Criminal Court Process for Jefferson County Idaho

Jefferson 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 Jefferson 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, Jefferson 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 Jefferson 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 Jefferson 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, Jefferson County or a city or town.  The prosecuting attorney for Jefferson 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 Jefferson 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 Jefferson 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 Jefferson 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 Jefferson 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 Jefferson 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.
