Boulder County Criminal Courts: From Arrest to Sentencing

Boulder County runs its state criminal cases out of two courthouses. Both use the name Boulder County Combined Court, and both hold a County Court and a District Court. The County Court hears petty offenses, traffic cases, misdemeanors and the early steps in felony cases. The District Court hears felonies once they are filed there, plus cases about young people accused of crimes.

  • Boulder County Justice Center, 1777 6th Street, Boulder, CO 80302. Main court number: (303) 441-3750
  • Longmont courthouse, 1035 Kimbark Street, Longmont, CO 80501, serving Longmont and the county’s eastern plains towns; phone (720) 564-2522.

Boulder County is the whole 20th Judicial District, one of 23 in Colorado. Boulder County voters alone choose the District Attorney, whose office handles state criminal charges. Many cities also have their own municipal courts for breaking local laws, such as Boulder, Longmont, Louisville, Lafayette and Superior, and city attorneys prosecute those cases. (Denver, nearby, is a special case: its County Court is a city court run by the City and County of Denver, not the state.)

Free ways to look up a case: The Colorado Judicial Branch has no free online system for reading criminal case files. For free, you can search the statewide court docket page for hearing dates, ask for records with the branch’s online request form, or call the clerk in Boulder. Several paid websites let you search records for a fee, and the state lists them in its access guide for public records.

Federal crimes: Charges under U.S. law belong in Colorado’s federal district court, which hears Boulder County cases at the Alfred A. Arraj U.S. Courthouse, 901 19th Street, Denver. Common federal cases include online child exploitation, computer hacking, investment fraud and drug trafficking. Location can make a crime federal too. The Roosevelt National Forest and the Wild Basin corner of Rocky Mountain National Park are federal land, and so are federal science labs in Boulder. Boulder County has no Indian reservation.

Misdemeanor cases: shoplifting, a first DUI, minor assault, trespassing

A misdemeanor is a crime that can mean county jail, not state prison. In Boulder County, many people get a summons, a paper that orders them to court in Boulder or Longmont on a set day. People who are arrested go to the Boulder County Jail. Everyone booked on Airport Road is owed a judge without unnecessary delay; the bond decision is due within 48 hours of arrival at the jail. Bond is the list of conditions, sometimes with money, that lets someone leave while their case goes forward. For petty offenses and most traffic offenses, Colorado does not allow cash bond.

At the opening hearing, a Boulder judge states the charge, covers your rights, and takes your plea. The state public defender’s Boulder office is at 2555 55th Street, Suite D-200, Boulder, (303) 444-2322. Boulder judges appoint those attorneys when a defendant faces possible jail and lacks the money to hire counsel. Should the public defender be conflicted out, the Office of Alternate Defense Counsel supplies a replacement. People with active warrants can also use the court’s walk-in warrant process to clear them up.

A misdemeanor case may end in a plea bargain or a dismissal. Boulder's DA offers diversion, which lets people complete programs and avoid a conviction. If there is a trial, it has six jurors. Colorado’s current limits, in place since 2022, are 364 days and $1,000 for a class 1 misdemeanor and 120 days and $750 for class 2. A first DUI comes with its own required penalties, like alcohol education and license loss.

Under 18: Misdemeanors against minors are heard in the District Court’s juvenile division. A first case may go to the DA’s juvenile diversion program, where the young person makes up for the harm and the case is closed. City courts may hear some youth traffic or local-law cases. For a Boulder youth kept in custody, the detention hearing comes no later than 48 hours after being held, not counting weekends or holidays. Detained youth from the 20th District are held at state centers such as Prairie Vista Youth Services Center in Brighton or Platte Valley in Greeley.

Felony cases: burglary, identity theft, drug distribution, felony DUI

Felony cases, the ones that can mean state prison, start in County Court with an advisement and bond. After the DA files felony charges, the defense in more serious cases can request a preliminary hearing. This is not a trial. Instead, a Boulder judge simply checks for probable cause, meaning evidence strong enough that the person probably committed the crime, and must do so within 35 days of the defense’s request. If probable cause is found, the case moves up to District Court. Some Boulder cases are instead charged by a grand jury, residents who weigh evidence behind closed doors.

Then comes arraignment in District Court, where the person pleads. Once a defendant pleads not guilty, the 20th District has six months to begin trial, plus any extra time the defense requests. Felony juries have 12 members.

Felony classes go from 1 to 6, plus drug felonies DF1 to DF4. The presumptive prison range for each: class 2, 8 to 24 years; class 3, 4 to 12; class 4, 2 to 6; class 5, 1 to 3; class 6, 1 to 1.5 years. Some people get probation, community corrections or a treatment court instead. A fourth DUI is a class 4 felony.

Under 18: Teen felony cases stay in Boulder County’s juvenile court, where the judge can order probation, therapy, restitution or a state youth commitment. For serious charges, the DA may ask a judge to hold a transfer hearing to decide if the case should move to adult court.

Violent felony cases: murder, sexual assault, aggravated robbery

Boulder and Longmont courtrooms handle violent felonies in the same way, but bond is harder to get. A judge can deny bond in a first-degree murder case if the proof is strong. Many violent charges come with a “crime of violence” finding (C.R.S. 18-1.3-406), such as when someone was armed with a deadly weapon or left a victim seriously injured. That finding means prison no matter what, for a term between the midpoint and double the top of the standard range. In practice, a Boulder second-degree murder sentence falls between 16 and 48 years, and aggravated robbery between 10 and 32.

Colorado classifies first-degree murder as a class 1 felony, and an adult who is convicted is sentenced to life without parole. The death penalty was repealed as of July 1, 2020. Some sexual assault sentences have no fixed end; the parole board decides later if release is safe. Boulder crime victims have rights under article II, section 16a and the state Victims’ Rights Act, among them updates on each court date and a turn to speak when sentence is pronounced. The DA’s victim-witness staff helps them.

Under 18: Teens aged 16 or 17 can be charged in adult court from day one by Boulder’s DA, but only for the most serious felonies, those in classes 1 and 2, and for certain violent sex crimes; this is called a direct file. Other youth reach adult court only after a judge orders a transfer, and for the gravest crimes Colorado allows that from age 12. Life without parole is never an option for a crime committed under age 18. Juvenile court’s most serious option is the aggravated juvenile offender sentence, up to seven years with the Division of Youth Services.

Boulder County Colorado Criminal Court System - Definitions

It might be helpful to define some words that will be used on this site, when explaining the Colorado 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 Boulder 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 Colorado, Boulder 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 municipal or Boulder 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 Boulder 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 has the opportunity to “bail or bond out” before being detained.

The prosecution, sometimes called “the government” or “the people” or “the state” is the side that press the charges and seeks punishment for the offense. These are attorneys that work for the state of Colorado, Boulder County or a city or town. The prosecuting attorney for Boulder County or the district is called the District Attorney.  A U.S. Attorney or Assistant 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 municipal 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 municipal 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 or not 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 Boulder County or municipal 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 Boulder 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. Jailors, law enforcement and prosecutors do not have authority to set bail, a judge or court officer in the {county extended} or municipal court sets bail. Judges in Colorado 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 to 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 to pay the court.  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.  

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 Colorado, {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 Colorado.

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 Boulder County, and it must be worth at least the amount of the bond.

An Unsecured Bond is when the defendant is released without paying bail upfront, but they must pay the full amount if they do not appear in court.

A Secured Bond is when the defendant pays a portion of the bail up front. If they show to court, they would get the money back and if they don’t show up to court, would have to pay the entire bail amount.

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 Colorado, the state rather than local courts fund indigent defense and have a network of public defenders who handle the majority of the cases.

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. . The attached links have a list of pro bono organizations in Colorado. Here and here.

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 in Colorado.

A district court can refer to the first level of the legal system, or a minor court. District courts are located 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 courts in Colorado, 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 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 if 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 non-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.

Colorado Felony vs Misdemeanor

In Colorado, a misdemeanor is punishable by fine or jail time of up to 18 months or both. The person is put into a county jail and not a state prison. There are 3 main classes of misdemeanors, Class 1 being the most serious and Class 3 being the least serious and there are also Unclassified misdemeanors which carry their own fines and sentencing range.

Misdemeanors are further broken down into traffic misdemeanors, as in T1 or T2 traffic offenses and regular misdemeanors, M1, M2 and M3. Examples of misdemeanors are DUI and DWAI depending on priors, careless driving, some domestic violence, forgery, indecent exposure, obstructing a police officer, theft less than $2000, resisting arrest, prostitution and underage drinking.  

DM1 and DM2 are two classes of drug misdemeanors where the maximum possible punishment is 18 months.  

A felony crime in Colorado is divided into 6 different classes which are general guidelines and are based on the crime, prior criminal history and other factors. Class 1 is the most serious felony and Class 6 the least serious with a minimum of 18 months jail time. Examples of felony crimes are murder, rape, theft, aggravated assault, kidnapping, identity theft and four or more DUI/DWAI.  

Colorado also has 4 types of drug felonies with prison sentences ranging from 6 months to 32 years in prison.

It is important to note that depending on severity, crimes can be charged as either a misdemeanor or a felony. For instance, DUI or DWAI may be charged as a misdemeanor or a felony depending on how many prior convictions one has. There is misdemeanor child abuse and felony child abuse, misdemeanor domestic violence and felony domestic violence. Often, tickets are written by law enforcement for alleged crimes, but once the district attorney reviews the elements of the offense, adjustments are made to the level of what is actually charged. 

The Boulder 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 Boulder County Clerk of Court website. If you do not pay your fine on time, you can lose your driver’s license, have to 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. 

Colorado Criminal Court System - How it Works

In Colorado, criminal cases are handled in the county courts, district courts and appeals are heard in the Court of Appeals or Supreme Court.

Municipal courts, also named city courts handle cases that pertain to violations of city laws or lesser crimes that occur within the city limits.  Examples of cases seen in municipal courts include animal control issues, traffic tickets and disturbing the peace.

County courts handle misdemeanors and more serious traffic cases. The county court can also process felony cases that will be prosecuted in district court.

District courts handle misdemeanor trials that are referred from the municipal and county courts and prosecute felony cases that originated in the county court or in the district court.  

There is a juvenile division within the district courts for offenders under the age of 18. Here is a link to the Colorado juvenile justice and prevention site.

Specialty courts or problem-solving courts are being adopted in many states as a way 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. The state of Colorado has the following problem-solving courts: Adult Drug Courts, Juvenile Drug Courts, DUI Courts, Adult and Juvenile Mental Health Courts, Family and Dependency/Neglect Courts and Veterans Treatment Courts.  The following is a link to Colorado’s problem-solving court system.

The Colorado 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 Colorado 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 question on the state laws or procedures that lead to the appeal.  

The criminal cases are usually referred from the district courts of appeal.

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 Colorado 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 Colorado.
